Omega-6 Fatty Acids Compromise Your Health

In an editorial of the October 2019 edition of LifeExtension William Faloon explained that omega-6 fatty acids compromise your health. He focused particularly on memory loss and the development of Alzheimer’s disease.

After a review of the medical literature he noted that Americans are eating too many foods that are laden with omega-6 fatty acids. Part of it is due to food processing with the wrong oils ). But the other problem is that processed foods also are full of omega-6 fatty acids. The merchants like omega-6 fatty acids, because they prolong the shelf life of products. But recent evidence shows that a high ratio of omega-6 to omega-3 ratio in our food can interfere with our memory and may even lead to dementia.

Evidence that omega-6 fatty acids are interfering with brain function

A recent publication analyzed 116 non-demented subjects aged 69 on average.

Blood tests were taken where 32 nutrients related to a Mediterranean diet were analyzed. In addition the researchers from the University of Illinois did functional MRI scans to assess higher brain function. The researchers also did cognitive tests to assess mental functioning.

  • The results of these experiments showed that higher lycopene levels had an association with better memory and higher executive function.
  • Subjects with higher carotenoids and trans lutein showed higher intelligence on testing.
  • B-vitamins that reduce homocysteine (vitamin B2, folate and vit. B12) and vitamin D showed an association with better executive functioning.
  • Two parts of memory testing showed that a proper balance of omega 6 to omega 3 ratio resulted in a better memory.
  • Higher omega-3 levels in the blood associated with higher overall intelligence and better executive function.

Impact of omega-6 on brain function

Researchers have proven that omega-3 fatty acids can help controlling inflammation in the body. This can prevent cardiovascular disease and neurodegenerative disorders like Alzheimer’s disease. However, our western food contains a surplus of omega-6 fatty acids, which causes inflammation in the body. It depends on our food choices, but it also depends on the preparation of the food. One chicken leg with skin contains about 1800 mg of omega-6 fatty acids. The process of deep-frying the same chicken leg increases the content to 4322mg of omega-6.

One deep fried KFC chicken breast with skin has 12,663 mg omega-6 fatty acids The reason is that a lot of the deep-frying oil is full of omega-6 fatty acids.

Cooking oils

Here is a run down of cooking oils. All of the cooking oils have a different mix of omega-3 and omega-6 fatty acid composition. Many also contain oleic acid, which is an omega-9 fatty acid.

Researchers have proven that omega-3 fatty acids can help control inflammation in the body. This can prevent cardiovascular disease and neurodegenerative disorders like Alzheimer’s disease.

As it is obvious from the table in the second last link olive oil contains 71.27% oleic acid, 9.76% omega-6 and 0.76% omega-3. It is the content of the majority of oleic acid (omega-9), which makes olive oil such healthy oil. Only two table spoons of olive oil per day will prevent heart attacks and strokes because oleic acid lowers the bad LDL cholesterol and increases the good HDL cholesterol. Olive oil removes beta-amyloid plaques inside the brain, which means it prevents Alzheimer’s disease.

Recommendation of best cooking oil

Considering that olive oil has such powerful healing properties, I recommend that you cook and bake with olive oil. Also use olive oil as part of your salad dressing. On the other hand avoid these oils: corn oil, sunflower oil, soybean oil, cottonseed oil and safflower oil. They contain too much inflammatory omega-6 fatty acids.

Our western food contains a surplus of omega-6 fatty acids, which causes inflammation in the body. It depends on our food choices what is in the food. But it also depends on the preparation of the food. One chicken leg contains about 1800 mg of omega-6 fatty acids. When it is deep fried with skin it contains 4322mg of omega-6.

One deep fried KFC chicken breast with skin: 12,663 mg Omega-6 fatty acids. One of the reasons is that a lot of the deep-frying oil is full of omega-6 fatty acids.

Math to calculate retained omega-6 from deep-frying

You notice that many cooking oils are high in omega-6. Soybean oil has 50.42% omega-6 in it. If you cook French fries or chicken in it and the food retains only 1 teaspoon of oil in it, that’s 5000 mg times 50.42%, which is 2521 mg of omega-6 added just from deep-frying your food.

Balancing omega-6 and omega-3 fatty acids

Omega-6 fatty acids are essential fatty acids that are mainly used for energy. But the problem is that in our western diet too many omega-6 fatty acids are in our food. Omega-6 fatty acids can be converted into arachidonic acid, which causes inflammation. This in turn can cause heart attacks and strokes on the one hand and arthritis on the other hand. In the past a healthy ratio between omega-6 and omega-3 was 4:1 or less. The average American now eats food with 16-times the amount of omega-6 fatty acids than omega-3’s. This is an omega-6 to omega-3 ratio of 16:1.

KFC chicken breast example

In the example of a KFC chicken breast with skin 12,663 mg omega-6 fatty acids are consumed. To balance this with omega-3 fatty acids the person would have to consume 3166 mg omega-3 fatty acids. One serving of wild salmon provides 2000 mg of omega-3. I take 3600 mg of molecularly distilled fish oil every day as a supplement (2 capsules in the morning and 2 at night). Together with the wild salmon this is 5600 mg of omega-3. This would result in an omega-6 to omega-3 ratio of 2.26:1, which is considered to be well balanced. But generally people do not consume so much seafood and fish oil supplements to balance the omega-6 fatty acids with omega-3. It comes down to be selective with your food choices.

Prevention of Alzheimer’s disease (dementia)

Since the mid 1980’s dementia cases have reduced by an average of 25%.

This is because people have become more conscious of healthier eating habits and supplements. More people take lycopene, a carotenoid supplement that helps prevent heart disease. Whatever helps the heart also helps the brain. Omega-3 supplements and consumption of seafood, especially wild salmon, is also useful. If people will reduce their omega-6 to omega-3 ratio to 4:1 or less, which too can help prevent Alzheimer’s disease.

Study to show that omega-3 fatty acids preserve the brain in older age

The following study looked at brain structure using MRI scans. 3660 participants aged 65 received MRI brain scans. The researchers recorded their food intake with questionnaires. They rescanned 2313 of these individuals 5 years later. The group highest in omega-3 consumption was compared to the group with the lowest omega-3 consumption. Blood tests were also done both initially and 5 years later to verify the omega-3 intake. The researchers found that the higher omega-3 group had less subclinical infarcts and the white matter of the brain was of a better grade. They concluded that fish consumption, the major source of omega-3 fatty acids, had a beneficial effect on brain health later in life.

Omega-6 Fatty Acids Compromise Your Health

Omega-6 Fatty Acids Compromise Your Health

Conclusion

Omega-6 fatty acids are abundantly present in junk food, deep fries, processed foods and polyunsaturated oils like corn oil, sunflower oil, soybean oil, cottonseed oil and safflower oil. Because food processors like the long shelf life of processed food made with these oils, people’s intake of omega-6 fatty acids has been climbing. Now the omega-6 to omega-3 ratio regarding the average American food consumption is about 16:1. It should be 4:1 or less. It is important that you learn what contains omega-6 fatty acids and that you start cutting down. You do need a certain amount of omega-6 fatty acids for cell energy, but most people do not get enough marine based omega-3 fatty acids. Wild salmon and other seafood provides omega-3 fatty acids.

Balancing omega-6 with omega-3

I have shown using an example how you can balance omega-6 and omega-3. Having the right ratio of omega-6 to omega-3 will also help you prevent dementia down the road. Consuming more olive oil can prevent heart disease and dementia as well. This contains oleic acid (an omega-9 fatty acid), which lowers LDL cholesterol and raises HDL cholesterol.

Slow Down Aging And Prevent Disabilities

You have seen it many times before: a man or a woman retires at age 65; for a while you see them around at social functions; then they are not seen any more and they return in a wheel chair only to die prematurely. You ask yourself: what can I do better to avoid this death trap?

There are several aspects to this equation: first, we would like to slow down the aging process. Part of this is to retain our physical functioning. In the following I am discussing the ingredients that are necessary to achieve the goal of aging in dignity, but avoiding disability.

It starts with a healthy mind set

You need to be optimistic and have a mindset of believing in yourself that you can do it. With a negative attitude, you will manage to find something to complain about, no matter how perfect the day has been. Negative thinking is rampant, and depression tends to be higher in the older population. If you suffer from depression or you had negative events such as accidents or abuse in the past, it is important to do some house cleaning. Do not be hesitant seeking professional help and counseling from a health professional to help you build up your self-esteem.

Regular exercise is important

A regular exercise program helps you to get your day organized. If you think that you are too busy to find the time to exercise, you are sacrificing your wellness and in fact you sabotage your health. It’s time to rethink your lifestyle! The reason you need exercise is to set the automatic pilot on staying healthy and active. If you are accustomed to sitting down in front of the computer or television set for hours, your muscles do not get the exercise they need. Fast-forward several decades and you will be one of those who rely on walkers, wheel chairs and assisted living establishments. Without training your muscles you are more prone to falls and injuries. Your balance organ is not getting the impulses it needs on an ongoing basis to prevent you from falls later in life. People in their 80’s are often stable up to the point where they trip and fall. I have seen many patients like this arrive in an ambulance where I was doing my shift as the emergency physician in a community hospital. When I summarize the fate of all of the people in their 80’s who had falls and broke their hips over the years, 50% of them made it through the surgery and went back home (often with a walker or in a wheel chair) or ended up in a nursing home; the other 50% died from complications of the surgery, often from heart attacks during the surgery or from clots in their pelvic veins or in the leg veins that dislodged and turned into pulmonary emboli. A fracture and in particular a hip fracture in your 80’s is a serious, potentially deadly accident. So, you need strong muscles and joints and you need strong bones. All of this comes free to you from years of regular exercise in your 60’s and 70’s.

Slow Down Aging And Prevent Disabilities

You guessed right: good nutrition is important!

Eat right and your body will function right. This is where a lot of people are sent on the wrong path due to clever advertising from the Agro Industry, Big Pharma, the American Dietetic Association and the United States Department Of Agriculture. So they preach that wheat and wheat products are good for you, but the lab tests show that it induces hyperinsulinemia and leads to diabetes. The genetic changes of wheat (“accomplished” through forced chemical hybridization in the 1970’s) are responsible for the metabolically very active wheat belly (accumulation of visceral fat) that Ref. 1 has described in detail. But others have researched this topic as well. Ref. 2 for instance confirms that gliadin, the glue in wheat, which allows dough to stick and makes it easy to create bread, bagels and pasta, is responsible for neurological issues like numbness of fingers and feet (peripheral neuropathy), balance problems and cognitive decline all the way to Alzheimer’s disease. If you continue to eat wheat and wheat products (all contained in conveniently packaged “processed” foods), you may very well find that your balance and muscle control will deteriorate by the time you are in your eighties. This condition is not new: one of the lecturers I listened to at McMaster University in Hamilton, Ontario in 1977 referred to those unfortunate individuals who were severely disabled as the “tea and toasters”. The tea in this case was probably the lesser evil, but the wheat induced malabsorption and malnutrition was a reality already in the mid and late 1970’s.

However, if you start eating organic foods to avoid the chemicals and estrogen-like xenoestrogens from pesticides, and you cut out sugar, high-density carbs and wheat products, you will no longer have problems with weight control and you will maintain your muscle, brain and nerve function. This is not what you learn from the regular agencies mentioned at the beginning of this paragraph, but Ref. 1 and 2 will fill you in on the details. Essentially, I follow a Mediterranean diet without sugar, starchy foods and wheat or wheat products. Ref. 2 stressed the importance of enough saturated and healthy fat (omega-3 fatty acid rich oils) in a balanced diet consisting of 20% protein and low carbs. No specific numbers were given regarding the %-age of fat. I would say that a limit of about 25 to 35% for fat would be reasonable except for the Inuit who are used to a fat content in their diet of 80%. The new thinking is that healthy fats are good for your brain and heart. Healthy fats are omega-3 fatty acids (EPA and DHA) derived from fish oil as they are very protective (anti-inflammatory) oils, so is olive oil and coconut oil. These latter two are anti-inflammatory monounsaturated fatty acids. Keep in mind that you want to change the ratio of omega-3 to omega-6 fatty acids (the ratio in this link is cited as omega-6 to omega-3) more in the direction of omega-3 fatty acids, so that the ratio will be between 1:1 and 1:3. Most Americans are exposed to ratios of 1:8 to 1:16 (too many omega-6 fatty acids in fast food and processed foods), which leads to inflammation of the arteries as well. Omega-6 fatty acids, found in safflower oil, sun flower oil, grape seed oil and canola oil are bad for you when not balanced by enough omega-3’s (flax seed oil and fish oil) as they lead to inflammation through the arachidonic acid system in the body. It may be a surprise to you that saturated fats are OK: animal fat like butter, lard, cream, ghee (clarified butter), and other animal fats provided they come from clean (not antibiotic or bovine growth hormone treated) animals. Buy organic and buy organic meats as well such as grass fed beef and bison, chicken and turkey.

Here is an example of what a day would look like nutritionally in terms of a breakfast, lunch and dinner (recipes by Christina Schilling):

Breakfast:  Great Greens Omelet

(2 servings)

1 tablespoon olive oil or coconut oil

3 chopped green onions

3 cups spinach leaves or a mix of greens: kale, spinach, Swiss chard

1 red pepper cut into strips

3 eggs and 3 egg whites

2 tablespoons grated Parmigiano

In non-stick pan sauté green onion, greens and pepper strips in oil, stir eggs and egg whites and pour over the vegetables, sprinkle with Parmigiano. Cook on medium heat, till the egg mixture has started to set. Turn over and briefly let cook. Remove from pan, divide into two portions and sprinkle with a bit of salt (optional). Serve with salsa and guacamole.

Lunch: Oriental Salad

(2 portions)

1 small Sui choy cabbage (Napa cabbage)

2 cups mung bean sprouts

1 small daikon radish, shredded to yield 1 cup

1 red pepper, cut into thin slices

3 green onions, chopped

1 medium sized carrot, cut into matchstick size pieces

1 can sliced water chestnuts, rinsed.

Dressing: 2 tablespoons sesame oil,

2 tablespoons rice vinegar,(light balsamic vinegar works too)

1-tablespoon tamari soy sauce

1 tablespoon Thai sweet chilli sauce

1-teaspoon fresh grated ginger

3 tablespoons chopped fresh cilantro

Prepare all vegetables and put into salad bowl. Stir all dressing ingredients together and pour over vegetable mix. Stir gently, cover and refrigerate. This salad can be consumed immediately or kept refrigerted for a day. To complete the salad with a protein portion add your choice of 6 oz. cooked shrimp or the same quantity of cubed or sliced grilled chicken.

Dinner:  Florentine Chicken

(2 servings)

1 large boneless chicken breast

1 tablespoon of chopped fresh basil-alternatively use 1 teaspoon dried basil.

1 tablespoon grated Parmigiano

4 thin slices prosciutto

1 tablespoon olive oil

2 tomatoes- cut into halves

3 chopped green onions

2 cups baby spinach leaves

pinch of salt

Spread chicken breast flat and top it with the basil, Parmigiano and prosciutto slices. Fold into half an hold the stuffed chicken breast together at the edges with a toothpick or two. Heat olive oil in frying pan, add onion and tomato slices and put the chicken breast on top. Put lid on the pan, and cook at medium heat till the chicken is cooked through. If you test with a fork, the juices will be clear. Remove vegetables and chicken from pan, put on serving plate and keep warm. Remove toothpicks from meat, and cut chicken breast into two portions. Put spinach into pan and let the leaves wilt at medium heat (cover with lid). Put spinach on the side of the chicken and tomatoes, and sprinkle with a bit of salt.

Dessert after dinner: Berry Sorbet

(2 servings)

2 cups of deep frozen berries (strawberries, blueberries or a berry mix, no sugar added)

¾ cup of organic yogourt or goat’s milk yogurt

a few drops of liquid stevia or small amount of powdered stevia-to taste.

Put into blender and process till smooth. You will have to open the blender jar to stir the contents in between. Serve with a dollop of whipped cream,  if desired.

What about the “slow down” of menopause and andropause?

It is a fact that as we age, our hormone glands do not produce as much hormones as when we were in our 20’s and 30’s. But if you find a health care provider who is interested in anti-aging medicine (there are about 26,000 physicians, chiropractors and naturopaths who are members in the A4M), your hormones can be measured accurately from saliva and blood tests. This will tell whether you are hypothyroid, deficient in sex hormones and whether you should be supplemented with the missing hormones in adequate doses through bio-identical hormones. For instance, women are often deficient in progesterone in menopause and men deficient in testosterone. Treatment needs persistence and patience, as it often takes months for the patient to feel better and up to 2 years, to find the exact balance for you where the hormones are re-balanced and your symptoms of tiredness, insomnia, hot flushes etc. disappear. All our body cells have hormone receptors that require stimulation for the cells to function normally. Your health professional needs to pay attention to this and not just treat your symptoms symptomatically. When your hormones are in balance and you take a few supplements, your bones will be strong (no osteoporosis), your brain will be clear, your hearing perfect, and your balance great. You will be much less likely in your eighties to fall and break a bone and your mind will be clear and sharp.

Stress management

As the baby boomers age, they need to be aware of the stress in their lives. You may have been accustomed to having lots of energy when you were in your child rearing years or in your active professional career. Often we do not even notice that there may be stress in our lives. But your adrenal glands know. This is really a subpart of what I said of hormones: they need to be in balance. But cortisol, which is produced in your adrenal glands, is different from the menopause/andropause hormones. Corticotrophin-releasing hormone (CRH) from the hypothalamus and adrenocorticotrophin hormone (ACTH) from the pituitary gland are the rulers of the adrenal glands. And it is how you handle stress when you are in your 40’s, 50’s and 60’s which will determine whether you come down with adrenal fatigue, various degrees of adrenal insufficiency or not. Ref. 3 is a whole book that deals with this topic. Here I like to mention only that the best test to diagnose adrenal problems is a four-point saliva hormone test for cortisol. You connect the four points and get a curve where the cortisol level is expressed as a function of time. If this curve is below the lower normal range, which the laboratory provides for you, you need to be managed by a knowledgeable health care professional in order to build up the reserves of your adrenal glands. Yoga, meditation, deep prayer, self-hypnosis and enough regular sleep are all proven methods to overcome any stress related issues. Sometimes more effort is needed to rebuild the adrenals by specific herbs or porcine adrenal gland cortex extracts. Your health care provider can tell you more regarding this.

Useful supplements

1. On March 17, 2013 I wrote in a blog about prevention of osteoporosis the following summary:

“The best combination is 1000 mg (or 1200 mg as per National Osteoporosis Foundation recommendation) of calcium per day together with 400 to 800 IU of vitamin D3 (for cancer prevention you may want to take 4000 IU to 5000 IU of vitamin D3 per day instead monitored by a 25-hydroxyvitamin D blood level test through your physician) and 100 micrograms of vitamin K2 (also called MK-7). In the age group above 50 missing hormones such as bioidentical testosterone in men and bioidentical progesterone/estrogen combinations in women should be given as well. This works best, if you also watch your weight, cut down your alcohol consumption to a minimum (or better cut alcohol out altogether), exercise regularly (this builds up bone and muscle strength) and stick to a balanced diet resembling a Mediterranean or zone type diet (low-glycemic,  low fat, wheat free and no sugar).” I would add in view of Ref. 1 and 2 that “low fat” should now be replaced by “balanced fat diet”. With this I mean that nuts, almonds, olive oil, unsalted butter are allowed within reason. Lately there have been new insights that some cholesterol is needed for normal hormone production. What needs to be cut out are omega-6 fats and trans fats.

2. Omega-3-fatty acid supplements from molecularly distilled fish oil at a good dosage (3 to 6 capsules a day) will prevent chronic inflammation that often causes arthritis. Chicken cartilage (UC-II) from the health food store will desensitize your system in case you have rheumatoid arthritis or osteoarthritis. This will prevent crippling arthritic disease down the road.

3. Mitochondrial aging (the mitochondria are the energy packages in each body cell) is slowed down by the two supplements ubiquinol (=Co-Q-10, take 400 mg per day) and 20 mg of PQQ (=Pyrroloquinoline quinone). Co-Q-10 repairs DNA damage to your mitochondria and PQQ stimulates your healthy mitochondria to multiply. Between the two supplements you will have more energy.

4. Vitamin C 1000 to 2000 mg per day and a multivitamin supplement help to support the rest of your metabolism. Some may want to add PS (Phosphatylserine) 100 to 200 mg per day, which works together with vitamin D3 for Alzheimer’s prevention.

Conclusion

By now you noticed that nothing comes from ignoring the fact that we are aging. We need to pay attention to our body functions and think about what we can do to make us stronger. In the end we are our own caregivers. When we are in our eighties, we should still be active and our brains should function with a lot more experience than in our past. Our bones will be strong and our balance should prevent us from falling. I do not want to use assisted living and I do not like the confinement of a wheel chair. In the meantime I am going to carry on dancing.

Dietary Habits Help For Clear Skin

Acne can be a bothersome skin condition that is not only a source of embarrassment to adolescents but it can plague adults as well. A lot of foods have been associated with the annoying “zits” from chocolates to French fries or junk food. More research has come up in recent years, and some new facts have emerged. Clement Adebamowo of the Harvard School of Public Health in Boston studied 4,000 teenage boys and found a significant association between the intake of skim milk and the development of acne. There are numerous explanations for the dairy-acne connection. According to US doctors Alan Logan and Valori Treloar there are at least 4 precursors of the “acne hormone” dehydroepiandrosterone in milk from pregnant cows. Even though milk has a low glycemic index research has substantiated that milk based foods increase levels of insulin. Insulin in turn seems to be one of the major players when it comes to skin fat production (sebum). This leads to the blockage of skin follicles and the development of blackheads and acne. Lacks of dietary oxidants are also putting fuel on the fire of acne. Acne sufferers demonstrate lower antioxidant blood levels and as a result there is no ammunition to fight the skin inflammation of acne. Other foods contributing to this problem are omega-6 rich oils (sunflower, safflower and soybean).

Dietary Habits Help For Clear Skin

Dietary Habits Help For Clear Skin

Strong allies to fight the inflammatory process of acne are foods that are rich in omega-3 fatty acids such as salmon, mackerel or sardines. The intake of fruit and vegetables is beneficial (acne sufferers generally eat fewer fruits and vegetables than those who have a clear skin.) A trial by Robyn Smith of RMIT University in Melbourne, Australia showed that acne patients who were instructed to consume a low glycemic diet high in protein had significantly less acne lesions that their counterparts. This dietary approach reduces androgen levels. Beside a dietary approach there is still the need for dermatological input. Using both avenues acne sufferers will reap the most benefits.
