Intelligence of the human brain

National Train Your Brain Day is observed annually on October 13. The observance was created to encourage all of us to exercise our brain and improve our cognitive skills. Doing word puzzles and number games, playing Bridge and reading are every-day activities that are good for the brain. But there are many other things you can do.

  1. Dance as though no one is watching. My book “Calmer Waters: The Caregiver’s Journey Through Alzheimer’s and Dementia” includes a 21-year-long study that was summarized in an article that appeared in the New England Journal of Medicine in 2003. The study found that when compared to 11 other activities including team sports, swimming and bicycling, dancing is the best activity for supporting cognition and staving off mental decline. In fact, the more complex the dance, the better it is for enhancing problem-solving skills and memory. You don’t have to be a great dancer. Just put on your favorite dance music and let loose in your living room. Or, find a dance partner and learn how to salsa, tango, or swing.
  2. Play an instrument. Numerous studies have indicated that listening to music and playing an instrument can reduce anxiety and depression and support cognitive functioning. Playing an instrument sharpens your concentration, boosts listening skills, and supports your time management and organizational skills. The efficacy of music therapy A Study done at the Auditory Neuroscience Laboratory at Northwestern University in Evanston, Illinois, and led by Nina Kraus, shows that musicians suffer less from aging-related memory and hearing losses than non-musicians. It is believed to be the first study to provide biological evidence that lifelong musical experience has a good impact on the aging process. Kraus says the research shows that playing an instrument helps hearing and memory, which is among the most common complaints from normal aging.
  3. Exercise! Dr. Monika Fleshner, researcher/professor at the University of Colorado, Boulder, and contributor to “Calmer Waters,” has spent her career showing that exercise is vital to reducing stress and supporting healthy mental function. “Physically active individuals are stress robust,” says Fleshner. “They demonstrate both stress resistance and stress resilience.” Exercise seems to buffer many of the deleterious consequences of stress, including poor memory. Scientists have also found that exercise encourages the growth of new brain cells in the hippocampus, the area that is crucial to memory and learning.
  4. Say it out loud. When I meet someone for the first time, I inevitably look in the person’s eyes and don’t even listen to their spoken name. As a result, I rarely remember the person’s name. Next time, I will heed the expert advice of repeating the person’s name. This is considered the easiest way to remember everything from where you put your keys to your grocery list. Say it out loud to yourself, or mouth the words, in order to remember quickly.
  5. Get a good night’s sleep. According to a study published in the journal Neuroscience (June 30, 2005) sound sleep triggers changes in the brain that help to improve memory. New memories are formed within the brain when a person engages with information to be learned (for example, memorizing a list of words or mastering a piano concerto). However, these memories are initially fragile. In order to “stick” they must be solidified and improved. This process of “memory consolidation” occurs when connections between brain cells as well as between different brain regions are strengthened, and for many years was believed to develop merely as a passage of time. More recently, however, it has been demonstrated that time spent asleep also plays a key role in preserving memory. So, do your best to work on sleep hygiene. Unplug at least an hour before bed, soak in tub filled with Epsom salts, play soothing music, make sure the room is not too warm, etc. And, never go to bed mad.
  6. Doodle. In memory tests, doodlers performed 29% better than non-doodlers when asked to recall names and places, Experts say doodling doesn’t tax the mind and allows us to concentrate on the task at hand. It stops us daydreaming, too, which is distracting. The same theory holds for coloring in the beautiful new adult coloring books that have become popular the past several years.
  7. Learn something before bed. If you want to consolidate a memory go through the information right before you fall asleep. You’ll have few, if any, interfering memories so you’ll remember it the next day.
  8. Feed your neurotransmitters. These are the chemicals that allow your neurons to talk to one another. They are vital to memory, focus, learning, energy and happiness. Acetylcholine is the primary carrier of thought and memory, and if you don’t have enough of this important neurotransmitter, you will probably have memory and cognitive problems. For healthy acetylcholine production, make sure you’re getting the nutrients that it is made from. Dr. Dharma Singh Khalsa, author of Brain Longevity (Warner Books, Inc. 1997) and the president and medical director of the Alzheimer’s Research and Prevention Foundation in Tucson, Arizona, suggests supplementing with choline, which is present in high amounts in lecithin. Lecithin is available in capsule, granule, liquid, tablet and powder form. The recommended therapeutic dose is 2500 to 3000 mg. four times a day, for a total daily dose of 10,000 to 12,000 mg. In addition, it’s important to take 1000 mg. vitamin C, three times a day, along with 100 mg. of B5, which are needed to transform lecithin into acetylcholine. It’s also advisable to take B6 and zinc, which help in the synthesis of acetylcholine. The nutrient DMAE (dimethylaminoethanol) helps build acetylcholine levels. It is present in your brain in small quantities, and is also found in seafoods, including sardines. Since it is stimulating to the central nervous system, Dr. Khalsa suggests starting out with a low dose of about 40 mg. twice a day, and building up to 200 mg. daily, if you don’t feel overstimulated. 

 

 

 

 

 

5 Ways to get into the Zen of Caregiving

Posted on by

purity of the zen massageI have caregiver burnout. I cared for my husband, who had Alzheimer’s disease, for 10 years. Before that I flew back and forth from Colorado to Florida whenever one of my parents had a health crisis (which was frequent). My daughter just had a baby, and I’d love to be there for her, but my mother has pneumonia and congestive heart failure. I am torn between helping my daughter and her beautiful, young family, and my elderly failing mother. I am flying to Florida for a few days and then back to Colorado. And I will probably be doing this again in the coming month. I tell myself, “you need to take care of yourself. You need to keep your head above water.” Easier said than done. But I learned a lot during the course of my husband’s illness. I know how important it is to meditate, do yoga, dance and eat and sleep well.

Caregiving is a huge challenge, and it’s very easy to let the responsibility of caring for an ill friend or relative become a yoke around one’s neck. But with practice and mindfulness it can turn into a spiritual practice. How?

  1. When you wake up in the morning let your first thought be, “I’m going to have a great day. It will be filled with joy and laughter, and I will maintain equanimity.” Be grateful for your ability to see, hear, walk, and serve your loved one. Other affirmations that you might like: I will remain calm and present throughout the day. I welcome peace, trust, and acceptance into my life. I’m feeling strong and healthy today. I am a kind, compassionate caregiver.
  2. Instead of reacting with anxiety or impatience to a stressful situation or annoying behavior such as constant complaining, asking the same question repeatedly, pacing up and down the hall, stop and breathe. Take a deep breath and let it out slowly. Do it again, and again. Now stop and ask yourself how you feel? Not too bad. Stretch your arms straight up towards the ceiling. Lower them and do it again, one at a time. Roll your head gently to the right and then to the left, and then slowly in a circle. Look to your right, center and then to the left. Take another deep breath and let it out slowly. Feel your body relax.
  3. Focus on the present. Instead of worrying about taking your loved one to a doctor’s appointment and anticipating how he or she will react or what news you will hear, put your attention on something beautiful—inside your home or out the window. If the sky is blue, appreciate its beauty. Listen to the birds singing and appreciate the miracle of their song. Look at a painting on the wall and really look at the colors, the brush strokes, and the image. Imagine the spark that inspired the artist during the creative process, and let it inspire you to get through the day while maintaining a positive outlook.
  4. Light a candle and have your care partner sit down next to you. Enjoy the glow, letting it calm your nerves. Match your breathing to your care partner’s and find your peace.
  5. Keep a journal. It’s a wonderful, easy way to get your concerns, fears, hopes, and dreams out without relying on your therapist or best friend. Use a writing prompt to get you going such as “I never thought. . . . It’s so hard to . .. “I’ll always remember . . .

These are just a few things that can ease the stress of caregiving. Have courage; find strength from the simple things.

Do you still need to floss?

Teeth with dental floss for healthcare

Recently the Associated Press reported that there is very little scientific evidence backing the effectiveness of flossing. However, dentists agree that you absolutely should still floss. Here’s why: More than 500 different types of bacteria are found in dental plaque. Brushing removes most of the plaque from the surface of your teeth. But the plaque that hides in the hard-to-reach places, such as between your teeth and along your gum, can trigger an inflammatory response leading to gum disease (periodontal disease).

What is dental plaque?

Bacterial plaque is the principal cause of cavities and tartar. It is a thin, invisible film to the naked eye, which adheres firmly to the surface of teeth and gums. The bacteria in plaque develop by feeding on the residuals of food (especially the ones rich in sugar). These bacteria these bacteria then produce enzymes and acid substances that attack the enamel of the teeth, which gives rise to cavities. Eventually, dental plaque transforms into tartar and then into gum disease, which can degenerate into pyorrhea, a slow and relentless loss of teeth. This is how bacteria destroy the teeth.

Periodontal disease has been linked to diabetes, heart disease and Alzheimer’s disease.

Oral bacteria can migrate to distant sites in the body. Elderly and immuno-compromised patients, such as those suffering from cancer, diabetes or rheumatoid arthritis, may be especially vulnerable to systemic oral pathogens. Now researchers are asking if oral pathogens can also infect the brain with subsequent neuropathological consequences. Another theory is that pathogenic periodontal bacteria do not “infect” the brain but rather induce a systemic inflammatory response leading to injury of brain tissue.

Periodontal disease is also associated with weight loss and wasting, which might contribute to cognitive decline. Gum disease often results in tooth loss, which often leads to problems with chewing, swallowing and food selection. Individuals also poorly absorb nutrients from food when it is not chewed well. Evidence from several studies indicates deterioration in nutritional status in individuals missing teeth.

One study examined lifestyle factors of more than 100 pairs of identical twins. All of the pairs included one twin who had developed dementia and one who hadn’t. Because identical twins are genetically indistinguishable, the study involved only risk factors that could be modified to help protect against dementia.

Twins who had severe periodontal disease before they were 35 years old had a five-fold increase in risk of developing Alzheimer’s disease, the researchers found. Periodontal disease may be a marker for chronic exposure to disease that provokes an inflammatory response. Chronic inflammation can damage tissue, including the brain, which may contribute to the development of the disease. Based on the association with tooth loss, further investigation of inflammatory load as a risk factor for Alzheimer’s disease is warranted.

According to the U.S. Centers for Disease Control and Prevention, one out of every two American adults over the age of 30 has some form of gum disease. Flossing is a low-cost and low-risk way to prevent gum disease. Dentistry is definitely a medical profession that is attempting to decrease the number of patients it sees every year. With that said, despite what the Associated Press found in its research, almost every dentist in America will tell you to floss on. It’s a very easy way to prevent a host of other health problems.

 

10 Things to Remember if You Love a Person with Dementia

Mother and daughter

Daughter caring for her mother

It’s sometimes hard to love a family member who has dementia or Alzheimer’s disease. People with dementia can be quarrelsome, uncooperative, negative, whiney, belligerent or combative. They might get their nights and days mixed up, pace the floor for hours, wring their hands non-stop, or cry like a baby. They might ask you the same question twenty times in a row, refuse to budge when you need to get them to an appointment, or refuse to eat what you’ve made for dinner.

When the going gets tough, it helps to remember that you love the person who resides inside that body that is tight and tense and inflamed from amyloid plaque that has strangled the neurons and disrupted the neurotransmitters that allow thoughts to flow and emotions to stay even. He or she is the same person you married, the same loving parent who nurtured and guided you, the same sibling you shared holidays and outings with, or the same friend who offered a should to cry on or who helping you move to a new home.

When you’re about to lose it, walk out, or hide in the closet, stop for a moment and remember at least one of these 10 things about the person you lovingly take care of.

People with dementia and Alzheimer’s often feel:

  1. Embarrassed when you say, “ I just told you . . ..” Instead of reminding them that they forgot what you told them a second ago rephrase it, breaking it down into a simple sentence . . . or completely change the subject.
  2. Fearful because they don’t see things spatially the same way we do. Their sense of space is distorted and their vision gets skewed, not because there is something physically wrong with their eyes. But rather, the brain interprets what the eyes see, and when the brain doesn’t work right our perception gets distorted. Two things you can do to help are to put extra lights in dark areas of the living quarters and remove throw rugs in order to reduce falls.
  3. Lonely because they can’t communicate well, or some of their friends have “jumped ship.” Set up times for family or friends to visit or take your loved one on an outing.
  4. Confused because they don’t understand why they can’t drive anymore, or why they can’t go for a walk alone, or why they can’t remember where they live or what their son’s or daughter’s name is.
  5. Angry because the keys to the car have been taken away, or because they get frustrated when they can’t express their feelings or thoughts.
  6. Sad because they can’t read a book or newspaper, or can’t manage to engage in their favorite hobby or sport.
  7. Anxious because they can’t move as fast or get dressed by themselves or put on their shoes easily. Or, because they hear sounds that are disturbing or are bothered by someone else’s behavior.
  8. Nervous because they have lost their sense of balance and feel unsteady on their feet. Or because they don’t like the feel of water on their skin and don’t want to bathe and don’t want to be forced.
  9. Frustrated because they can’t write a check, figure out how much tip to leave, or remember how to use the TV remote control.
  10. Paranoid because they think someone is stealing their money or prized possessions.

When all else fails, take a deep breath and put on some music. It almost always uplifts the spirit—for both the caregiver and the person being cared for.

8 Ways to Eat Your Way to Healthy Aging

Posted on by

It’s Healthy Aging Month and it’s a good time to ask yourself “what am I doing to stave off chronic illnesses such as cardiovascular and Alzheimer’s disease, arthritis, Parkinson’s, osteoporosis and other age-related diseases? How can I age gracefully?”

Senior African American Couple Drinking Orange Juice

 

  1. Eating fish such as wild-caught salmon, sardines and other cold-water fish can protect you against Alzheimer’s disease and other forms of dementia. Numerous studies have shown that elderly people who did not have dementia had high blood levels of docosahexaenoic acid (DHA), an essential fatty acid found in cold-water fish, in comparison to those with dementia, who had on average 30% to 40% lower blood levels of DHA. Ways to increase your DHA intake: eat cold-water fish such as wild-caught salmon, sardines and mackerel, at least twice a week. Add flax meal to cereal and baked goods, sprinkle flax oil on your salad, eat a small handful of walnuts at least several times a week.
  2. Eat breakfast! It is the meal that you break your fast with. During the night our blood sugar levels drop, so it’s especially important to eat within one hour of arising and by 10am. Eating breakfast restores healthy blood sugar levels, but make sure your breakfast isn’t coffee and a doughnut. Have some protein and a healthy fat such as an omelet and avocado and a piece of whole grain or gluten-free toast. It’ll provide you with the energy you need to get through the morning while maintaining a sense of equilibrium. My favorite cool weather breakfast is eggs (any way you like them), a side of beans such as black or pinto, and a pile of sautéed greens. When the weather is hot, I prefer home-made granola made with oats, a bit of coconut oil and maple syrup, coconut flakes, and lots of nuts including almonds, walnuts, cashews, and pumpkin seeds. Add chia seeds, flax meal, yogurt and fresh berries and you’ve got a breakfast for champions.
  3. Avoid commercially processed meats and favor grass-fed meats, free-range chickens and eggs fed an organic, non-GMO diet. And limit your meat consumption to no more than twice a week.
  4. Eat like a rabbit to reduce your risk of stroke, dementia, macular degeneration, and other chronic illness. Veggies are low in calories and high in fiber. Fruits are also high in fiber and like veggies, contain numerous vitamins and minerals. Just like people, fruits and vegetables come in a variety of shapes, sizes and colors. And it’s the colors that identify many of the bioactive substances called phytonutrients that give us antioxidant protection and other special health benefits. The scientific community has produced a large body of research showing the potential of these super nutrients. Compared with people who eat few fruits and vegetables, populations that consume a large variety and generous amounts of plant foods enjoy longevity and reduced risk of disease. For example, the people of Okinawa have a long life expectancy, numerous centenarians, and a low-risk of age-associated diseases. Their diet is low in calories, fat, sugar, salt, and meat and dairy products. Instead, Okinawans eat fish, tofu, whole grains, and lots of fruit, dark green leafy vegetables, onions, green peppers, sea vegetables and sweet potatoes—which are all dense in phytonutrients and antioxidants. These islanders are known for a low-stress, carefree and relaxed attitude. Their rates of stroke, dementia, cancer and heart disease are also the lowest in the world. For every 100,000 people in Okinawa, 30 have passed their 100th birthday, one of the highest rates in the world.
  5. Eliminate soft drinks; they increase your risk of insulin resistance and diabetes. Instead, drink plenty of water to hydrate your brain and body.
  6. A cup of Joe will do you good . . . just don’t overdo it and don’t add lots of cream of sugar. Researchers from the University of Scranton found that coffee is the number one source of antioxidants in the U.S. diet. Coffee has been shown to improve mental acuity. In fact, a study published in the Journal of Alzheimer’s Disease (2012) found that people older than 65 who had higher blood levels of caffeine developed Alzheimer’s disease two to four years later than people with lower caffeine levels. The study included 124 people who had mild cognitive impairment (MCI). Typically, 15% of people with MCI will go on to develop full-blown Alzheimer’s disease each year. The study participants who had less than 1,200 ng/ml of caffeine levels in their blood developed Alzheimer’s disease. This is equivalent to drinking several cups of coffee a few hours before their blood was taken. The people whose memory loss did not progress to full-blown Alzheimer’s disease had higher levels of caffeine in their blood. Coffee appeared to be the only source of caffeine for the participants in the study. Some big caveats: if you have high blood pressure limit your coffee intake to 2 cups a day, and avoid drinking it before exercise or physical labor which both naturally raise blood pressure. Coffee acts as a diuretic, depleting the body of necessary fluids, so make sure you drink a glass of water for every cup of coffee you drink. Coffee can raise homocysteine levels, an indicator and risk factor for cardiovascular disease. It can also cause headaches, fatigue, depression, anxiety and drowsiness if a coffee drinker forgoes his or her usual daily dose of caffeine. So be smart and listen to your body.
  7. If you can’t drink coffee, consider green tea. Scientists have found evidence that green tea extract can help fight everything from glaucoma to prostate cancer and leukemia. Now, a research team composed of chemists, biochemists and biophysicists at the University of Michigan has found a new potential benefit of green tea extract: preventing the clumping of proteins associated amyloids in the brain, which is associated with Alzheimer’s disease and other neurodegenerative conditions. The study found that the specific molecule in green tea, ( — )-epigallocatechin-3-gallate, also known as EGCG, prevented aggregate formation and broke down existing aggregate structures in the proteins that contained the metals copper, iron and zinc.At Tohoku University Graduate School of Medicine, researchers tracked the green tea consumption of nearly 14,000 people over age 65 for three years. The participants’ quality of life (measured in day-to-day activities such as getting dressed, walking the dog, and performing household chores) was examined in relation to how much green tea they drank. The authors found that the more green tea participants consumed, the longer they were able to ward off the difficulties associated with old age. The people who drank at least five cups a day were one-third less likely to develop disabilities than those who had less than a cup per day. Those people who averaged three or four cups a day had a 25 percent lower risk. Just remember that while green tea and its extracts are considered safe in small amounts, they do contain caffeine and small amounts of vitamin K, which means it could interfere with drugs that prevent blood clotting. So the next time you feel the need for a cup of coffee or black tea, consider drinking a cup of green tea instead. It just might help you maintain clarity of mind, healthy bones, and cardiovascular health well into your senior years.
  8. Herbs or adaptogens can be helpful for increasing energy without stimulation. An adaptogen is a natural substance—usually an herb—that helps the body adapt to stress by producing a calming effect on the whole physiology, and stress is often blamed with being the root cause of many illnesses and diseases. Phytosterols, the plant compounds in the herbs ashwaghanda, gotu kola, passion flower, schizandra, skullcap, rhodiola, and cordyceps have been scientifically shown to support the adrenal glands and healthy blood chemistry, and enhance the body’s ability to resist the ravages of stress. Valerian, Siberian ginseng, kava kava, oat straw, and hops also help reduce stress. These herbs can be taken as a tea or in the form of a nutritional supplement. Culinary herbs also have numerous health benefits. Turmeric, the spice used in Indian cooking, has dozens of studies backing up its ability to reduce inflammation, another major cause of chronic disease, and risk of Alzheimer’s disease. Cinnamon helps to stabilize blood sugar levels, which is vital to healthy aging. Oregano contains antioxidants that offer antibacterial protection. Garlic has been called the natural antibiotic, and ginger root has been used for thousands of years for its anti-inflammatory and anti-microbial effects. The list goes on and on.

Bon appetite!

The loneliness of caregiving: How to stay socially connected

Posted on by

Woman with mobile phone

My husband had younger-onset Alzheimer’s disease. The hardest thing for me during the duration of his illness was that I lost my companion. He was the person I made important decisions with. The person I went to movies with, ate dinner with, had interesting conversations with, traveled with, and shared delight with over the accomplishments of our children. He was the one I could complain to if I had a headache, stomach ache, or sore throat, without worrying about being called a hypochondriac or a baby. He was also the person who always cheered me on when I succeeded in achieving my goals.

When it came time to make the decision to move him to a memory care home, I especially missed having him help me decide on which room he’d live in, what type of furniture to buy, and the mattress he would sleep on. When it came time to bury him, it was agonizing for me to choose the plot of land where he would be laid to rest, and where I will be eventually interred.

During my many years of caregiving, I would often hide behind a mask of cheerfulness. It helped. I didn’t feel like a prisoner because I hired people to take my husband out to see a movie. Several of his friends kindly took him to lunch on a regular basis. It takes an effort to maintain friends and to stay socially involved, especially if you no longer work outside the home.

I promised myself that I wouldn’t let my husband’s disease ruin my life. I kept an active calendar filled with dance classes, lunches with friends, and even pursued a certificate in nutrition–all the while he was ill.

But it took planning and some might think I was a bit selfish. But when you look at the grand picture of caregiving, taking care of your personal needs is anything but being selfish. Studies show that 40 to 70 percent of family caregivers experience symptoms of clinical depression. One of the reasons, besides the daily stress, is isolation and loneliness.

Now for the lecture part: If you are a caregiver it is vital that you maintain a social network. Here are some ideas:

  • Stay connected with friends and family either through Facebook or another social media outlet, or by telephone or email, etc.
  • Make a lunch date with a friend at least once a week.
  • Many places of worship offer support for caregivers and families, including social events.
  • Go to a class—any kind of class: knitting, dance, weight training.
  • Join a support group—The Alzheimer’s Association offers classes and workshops for caregivers and for the person with memory loss.
  • Ask your friends and family for respite care. Have someone come over for a couple of hours a week so you can at least get out for a walk or go grocery shopping.
  • Go to the movies with a friend. It’s a great way to escape into another world for a few hours.
  • Call a best friend who is happy to talk; call someone who makes you laugh–laughter is truly the best medicine.
  • Bring your loved one to a Memory Cafe/Alzheimer’s Cafe. The challenges of living with memory loss can sever social connection at a time when it is needed most. Throughout the US and Europe, this casual social meeting is for caregivers and their care partner (the person they are caring for). Memory Cafes offer a way to socialize, explore art, music, poetry and listen to discussions and presentations. A Dutch psychologist opened the firs Memory Cafe in Holland. today there are about 200 Memory Cafes in the U.S.
  • Chat online with other caregivers. The Alzheimer’s Association offers chat rooms and so does the American Cancer Society. Check Elder Care Online for chat room and caregiver forum links. ElderCare Online’s Caregiver Support Network brings together online resources, groups and experts to create a virtual community dedicated to improving quality of life for you and your loved ones.

Antioxidants: Are they protective against dementia and stroke?

Posted on by
1

The journal Neurology recently published a study indicating that antioxidants do not reduce stroke or dementia risk. This study contradicted what other studies have shown and I want to present the opposing viewpoint.

“These results are interesting because other studies have suggested that antioxidants may help protect against stroke and dementia,” said study author Elizabeth E. Devore, ScD, of Harvard Medical School in Boston and Erasmus Medical Center in Rotterdam, Netherlands. “It’s possible that individual antioxidants, or the main foods that contribute those antioxidants—rather than the total antioxidant level in the diet—contribute to the lower risk of dementia and stroke found in earlier studies.”

Devore add that “This differed from an Italian study that found the higher total antioxidant levels were associated with a lower risk of stroke, where the variation from coffee and tea was lower, and the contribution from alcoholic beverages, fruits and vegetables was higher.”

The study followed more than 5,000 participants aged 55 years and older who provided information about their diets. Devore pointed out that most (90%) of the difference in the antioxidant levels in people’s diets was due to how much tea or coffee they consumed.

Researchers from the University of Scranton found that coffee is the number one source of antioxidants in the US diet. Study leader, Joe Vinson, Ph.D., said “Americans get more of their antioxidants from coffee than any other dietary source. Nothing else comes close.”

Sure, coffee offers some antioxidant protection. But you can get more bang for your buck with 5 to 7 servings of fruits and vegetables every day.

How many fruits and vegetables do you eat each day?

If you’re like most Americans, you’re probably not getting the recommended five to seven servings. Now more than ever we know why getting your greens, blues, reds, oranges and yellows is absolutely essential to good health and longevity.

Just like people, fruits and vegetables come in a variety of shapes, sizes and colors. And it’s the colors that identify many of the bioactive substances called phytonutrients that give us antioxidant protection and other special health benefits.

What are phytonutrients?

Phyto comes from the Greek word that means plant. Phytonutrients are the natural chemicals found in all plant foods—including grains, nuts and seeds—that help fine-tune all bodily functions and support our health. Phytonutrients contain potent antioxidants and other compounds that help slow down the aging process and prevent chronic diseases, including cardiovascular disease, diabetes and some cancers. On a day-to-day basis, phytonutrients help boost our immunity and support our overall well being, so we feel energized, uplifted and have a sparkle in our eyes.

How do phytonutrients reduce risk of disease?

  • Provide antioxidant protection
  • Support healthy immune response
  • Convert to vitamin A (from alpha- and beta-carotene)
  • Support healthy estrogen metabolism

Proven results

The scientific community has produced a large body of research showing the potential of these super nutrients. Compared with people who eat few fruits and vegetables, populations that consume a large variety and generous amounts of plant foods enjoy longevity and reduced risk of disease.

Take for example the people of Okinawa, who live on an island between Japan and Taiwan. They have a long life expectancy, numerous centenarians, and a low-risk of age-associated diseases. Their diet is low in calories, fat, sugar, salt, and meat and dairy products. Instead, Okinawans eat fish, tofu, whole grains, and lots of fruit, dark green leafy vegetables, onions, green peppers, sea vegetables and sweet potatoes—which are all dense in phytonutrients and antioxidants. These islanders are known for a low-stress, carefree and relaxed attitude. Their rates of stroke, dementia, cancer and heart disease are also the lowest in the world. For every 100,000 people in Okinawa, 30 have passed their 100th birthday, one of the highest rates in the world.

Free radicals and antioxidants

You’ve heard the terms a million times, but what exactly are they?

Free radicals are dangerous, highly reactive, unstable molecules that produce oxidative stress or cellular damage throughout the body, and play a primary role in the aging process. It’s impossible to be alive and not have some free radical damage—because free radicals are produced by normal processes in the body (like the release of adrenaline), and from environmental sources such as ultraviolet radiation, tobacco smoke, food additives and other pollutants.

You’ve seen what happens to an apple that sits on the counter for too long. It turns brown, just like the rusty nail that has been exposed to sun and rain. These are examples of oxidation. Once free radicals are released they multiply geometrically in chain reactions causing oxidative damage, unless they are stopped by antioxidants.

Antioxidants are molecules that donate an electron to the free radical. The free radical stabilizes and stops wreaking havoc in the body. Vitamins C and E are well-known antioxidant vitamins, and phytonutrients exert antioxidant protection, as well.

It’s important to get a variety of phytonutrients

Every plant contains several types of phytonutrients. These phytonutrients work synergistically with each other and with the phytonutrients in other plants to produce the beneficial effects in your body. This is why it’s important to eat a varied diet containing fruits and vegetables of all colors of the rainbow. For example, scientists are discovering that if the only vegetable you ate for dinner was carrots, the amount of antioxidant protection you’d get, and your body’s ability to convert alpha-carotene to vitamin A would be far less than if you ate carrots and kale and broccoli at the same meal.

The Okinawans enjoy their tea. But they also include plenty of vegetables and fish in their diet, which is something that is making headlines right now in regard to the benefits of the Mediterranean diet.
