Healthy Oils For A Healthy Body

Healthy oils for a healthy body? Quite frequently the news are full of articles that want to inform you what fat or oil to eat. At the end the consumer often faces information overload and confusion.

Here I am reviewing what we know about the various oils.

1. Coconut oil not as good as it was thought

This review article pointed out that coconut oil does elevate the bad cholesterol, called LDL cholesterol. This is not a desirable effect, as it can lead to heart disease and possibly heart attacks. On the other hand coconut oil also elevates HDL cholesterol, the good cholesterol that mobilizes LDL cholesterol. The article points out that coconut oil may be a better choice than butter. Butter does not elevate HDL cholesterol to offset the effects of LDL cholesterol. Researchers felt that the occasional use of coconut oil instead of butter would be justifiable. But they advised strongly against the daily use of coconut oil. Instead they recommended olive oil, canola or soybean oil, along with nuts and seeds, as your primary fats. I agree with olive oil, but have concerns about canola or soybean oil, as I explain it later in this article.

Dr. Andrew Weil reviewed coconut oil in Self Healing August 2014. He said that the effect on cardiovascular health remains largely unclear. He is not aware of any “study that has shown using coconut oil leads to significant weight loss”. It is basically a thumbs down assessment for coconut oil. You may want to use it occasionally for baking or a special Thai food meal.

Let’s remember that the long-lived populations such as in Okinawa and others never used coconut oil.

2. Polyunsaturated fatty acids used in processed food

news release in 2016 describes new FDA food guidelines. They recommend that saturated fat should not exceed 10% of the total daily caloric intake, but there are still different opinions: some studies show that saturated fat may not be responsible for hardening of the arteries. Other studies have shown that breast cancer is more common in persons who consume more saturated fat .

In the 1980’s the news came out that saturated fats would be bad for arteries. At that time there was a switch to polyunsaturated fatty acids. These consist of safflower oil, canola oil, sunflower seed oil, corn oil, soybean oil and grape seed oil.

However, the irony is that these vegetable oils were highly unstable and lead to oxidation causing heart disease and cancer.

In contrast olive oil is a much more stable oil. And long-lived populations in the Mediterranean seem to be the proof, that it is a healthy fat source for them and for us.

Personally I have cut out polyunsaturated fatty acids out of my food and I suggest you do the same. We know now that polyunsaturated fatty acids lead to inflammation via the arachidonic acid pathway. This can cause gout, arthritis, diabetes, and inflammation of the arteries with subsequent clots causing heart attacks and strokes. I don’t need all of these diseases, I am doing fine without polyunsaturated fatty acids.

3. Omega-6 to omega-3 ratio

The cell membrane consists of two lipid layers at a specific ratio of omega-6 essential fatty acids and omega-3 essential fatty acids. It also contains triglycerides, phospholipids and protein. Safflower oil, canola oil, sunflower seed oil, corn oil, soybean oil and grape seed oil are mostly omega-6 fatty acids and the type of polyunsaturated fatty acids that prevail in processed foods. With the consumption of too much processed food the body has a problem constructing cell membranes. As you can see by this link when you compare the metabolism of omega-6 fatty acids with that of omega-3 fatty acids, there is a fundamental difference. The linoleic acid of omega-6 fatty acids metabolizes into arachidonic acid, which causes pro-inflammatory mediators, PGE2 and LTB4. On the other hand with omega-3 fatty acids alpha-linolenic acid (ALA) is metabolized into EPA, DHA and the anti-inflammatory mediators PGE3 and LTB5.

Disbalanced omega-6 to omega-3 ratio

It is easy to understand why a surplus of omega-6 fatty acids from processed foods will disbalance the omega-6 to omega-3 ratio. This ratio should be 1:1 to 3:1, but many Americans’ omega-6 to omega-3 ratio is 6:1 to 18:1. Omega-6-fatty acids cause arthritis, heart disease and strokes. Be particularly careful in avoiding soybean oil, which is the most popular oil in the last few decades to foul up the omega-6 to omega-3 ratio through processed foods. Read labels to avoid soybean oil and other omega-6 fatty acids.

When it comes to balancing omega-3 and omega-6 fatty acids in your diet, be aware that nutritional balancing can help you restore the ideal omega-6 to omega-3 ratio of 1:1 to 3:1. An easy way is to simply cut out processed foods as much as possible. Supplement with molecularly distilled fish oil capsules to add more omega-3 fatty acids into your food intake.

4. Fish oil

What we learned from this is the importance of fish oil as a supply of omega-3 fatty acids. But nuts also supply us with omega-3 fatty acids. Eating fish three times per week is another way to get enough fish oil on board. There is a word of caution. Our oceans are so contaminated with mercury that you want to be careful and eat only fish low in mercury content. Avoid swordfish, tuna fish or grouper.

But wild salmon and mackerel are fish low in mercury and safe to eat. I would recommend that you eat seafood at least three times per week to have a good source of omega-3 fatty acid. In addition I would also recommend you take omega-3 supplements. I take it in the form of molecularly distilled high potency omega-3. I take 2 capsules twice a day. In addition I take 750 mg of krill oil once per day, another source of molecularly distilled marine omega-3 supplement.

5. Cold pressed virgin olive oil

Organic olive oil contains monounsaturated fatty acids that are neutral in terms of effects on the cardiovascular system. But it also contains a lot of polyphenols and among these in particular hydroxytyrosol that lower blood pressure and protects you from hardening of the arteries. This likely is the main reason why the Mediterranean diet is so healthy, apart from its emphasis on vegetables, which further makes it desirable. In a 2012 study from Spain it was found that mortality from heart attacks was 44% lower than that of a control group who did not incorporate olive oil in their diet.

Only two tablespoons of virgin olive oil per day protect you from heart disease. It does so by reducing the total cholesterol level in the blood as well as the LDL cholesterol level. At the same time the more polyphenol is contained in olive oil (such as in extra virgin olive oil), the more HDL your body will produce, which is essential to extract oxidized LDL from arterial plaque. On top of that polyphenol rich olive oil will increase the size of the HDL particles (these larger particles are called HDL2), which are more efficient in extracting oxidized LDL from arterial plaque.

Effects of olive oil

Olive oil has been shown to lower blood pressure and prevents heart attacks and strokes.

Sept. 2014 study in humans showed that higher polyphenol olive oil as found in extra virgin olive oil caused an increase in the more effective HDL2 particles, which cleans out plaque from arteries more efficiently than the regular, cheaper olive oil. You should use mainly olive oil for your regular cooking. Cold pressed, virgin olive oil is more expensive than the regular olive oil, but this is what has been proven to enhance health and to prolong life, if you consume it regularly.

Conclusion

Sometimes it is useful to think about what fats you are consuming. We tend to eat too many omega-6 fatty acids from processed foods. These are polyunsaturated fatty acids found in safflower oil, canola oil, sunflower seed oil, corn oil, soybean oil and grape seed oil. Food merchants use these polyunsaturated fatty acids to have a longer shelf life of their products. But the more omega-6 fatty acids we consume, the higher the omega-6 to omega-3 ratio gets. This leads to inflammation in the body and the arteries. It causes heart attacks, strokes and other illnesses. Years ago I cut polyunsaturated fatty acids out of my food intake. Instead I use organic cold pressed extra virgin olive oil. It is full of polyphenols (and among these in particular hydroxytyrosol). It lowers blood pressure and prevents heart attacks and strokes. I am not convinced that the hype around coconut oil can be verified. At this point I would suggest only occasional use of it.

You need to eat fish three times per week and other seafood as a source of omega-3 fatty acids. This is important to keep your omega-6 to omega-3 ratio well balanced. I also take fish oil supplements regularly like krill oil once daily and fish oil capsules twice a day. You can buy these molecularly distilled to ensure they are mercury contamination free.

Fish, The Good And The Bad

I am going to review fish, the good and the bad. Fish can be very nutritious, because it contains a lot of healthy omega-3 fatty acids. But because of pollution it also has various degrees of mercury, PBC’s and other impurities.

I will discuss the good about fish oil first. Later we will learn that wild salmon is one of the best fish to eat, while we should avoid tuna due to mercury pollution.

The good about fish

Omega-3 fatty acids, also called marine oil, is an essential fatty acid. It balances omega-6 fatty acids of which we eat too much. Processed foods are full of omega-6 fatty acids, because they keep a long time on the grocery shelves without turning rancid. But when the omega-6 to omega-3 ratio is getting higher than 3:1 we are experiencing a problem. The body stimulates the arachidonic acid pathway, a metabolic pathway that produces inflammatory substances and arthritis. An old home remedy for arthritis is to use fish oil (cod liver oil). It changes the omega-6 to omega-3 ratio back to more normal levels, which can help arthritis patients. Early stage of arthritis can even heal.

Many processed foods contain only omega-6 fatty acids, because this is the cheapest way to produce them (they are based on vegetable oils). Instead of this you want to eat healthy fats like omega-3 fatty acids contained in nuts and fish. You can also add molecularly distilled, high potency omega-3 fatty acids (purified fish oil) as a supplement to help restore the balance between omega-6 and omega-3 in the food you eat. Avoid omega-6 fatty acids that are derived from corn oil, safflower oil, grape seed oil, soybean oil, cottonseed oil, canola oil and peanut oil.

Compare the metabolism of omega-6 fatty acids with that of omega-3 fatty acids.

The linoleic acid of omega-6 fatty acids gets metabolized into arachidonic acid, which causes pro-inflammatory mediators, PGE2 and LTB4 as shown in the metabolism link. On the other hand with omega-3 fatty acids alpha-linolenic acid (ALA) is metabolized into EPA, DHA and the anti-inflammatory mediators PGE3 and LTB5.

It is easily understandable why a surplus of omega-6 fatty acids from processed foods will disbalance the omega-6 to omega-3 ratio. This ratio should be 1:1 to 3:1, but many Americans’ omega-6 to omega-3 ratio is 6:1 to 18:1. Omega-6-fatty acids cause arthritis, heart disease and strokes. Be particularly careful avoiding soybean oil. It has become the most popular oil in the last few decades to foul up the omega-6 to omega-3 ratio. We consume it through processed foods and cooking oils.

Omega-3 supplements

When it comes to balancing omega-3 and omega-6 fatty acids in your diet, be aware that nutritional balancing can help you restore the ideal omega-6 to omega-3 ratio of 1:1 to 3:1. An easy way is to cut out processed foods as much as possible. Supplement with molecularly distilled fish oil capsules to add more omega-3 fatty acids into your food intake. Here is an example of rheumatoid arthritis patients that received omega-3 supplements. After 24 weeks their joint swelling and tenderness decreased significantly.

Rebalancing the omega-6 to omega-3 ratio was able to treat depression as this research showed. This makes you wonder how much depression may be caused by overconsumption of processed food.

Dr. Blatman suggested the following doses of omega-3 supplementation for various purposes:

  • 1 gram/day as supplementation for healthy adults with a good diet
  • 1-3 grams/day for people with cardiovascular disease
  • 5-10 grams/day for patients with an autoimmune disease, with chronic pain or with neuropsychiatric conditions

He mentioned that these doses are empirical, but in his experience this is what really works. Due to quality differences he suggested that you buy fish oil capsules in a health food store. Stay away from discount stores (the quality is the worst) and drug stores.

Other healthy oils are olive oil and coconut oil. They are also useful for cooking.

The bad about fish

1. Mercury and other pollutant

Pollution of the air, soil and rivers is causing accumulation of mercury and other heavy metals in ocean water.

This affects fish that live in the ocean. There is a pecking order of predators with the larger fish feeding on the smaller fish. The bigger the predator fish, the more mercury and other pollutants they accumulate. According to this link the safest seafood is wild salmon, pollock and oysters.

Tuna is too high in mercury, so is swordfish, and shark is even worse. I only consume fish from freshwater lakes or rivers, as well as salmon, oysters and shrimp. This way I get the lowest exposure to mercury. Why is mercury bad for you? It is a neurotoxin. It can harm your brain, heart, kidneys, lungs and the immune system. Specific symptoms can include loss of peripheral vision and lack of coordination with balancing problems. There may be impairment of speech and hearing. The key is to avoid mercury exposure.

2. Rancidity of fish oil

Rancid fish oil contains free radicals that attack the lining of the arteries. There would be no point in taking fish oil, if it is rancid and destroyed what you want to protect. When fish oil is stored, it can interact with oxygen and form lipid peroxides, which are free radicals. The Council for Responsible Nutrition’s quality standards monitors rancidity in fish oil. Get fish oil that meets or exceeds the Council’s standards. If you refrigerate fish oil, it stays fresh longer.

Managing mercury pollution

  1. The first line of defense is to stick to the smaller fish. They are they prey of the large predator fish. The following fish/mussels belong into the low mercury group (alphabetical order): anchovies, catfish, clam, crab, crawfish, flounder, haddock, herring, mackerel, mullet, oyster, perch, pollock, salmon, sardines, scallops, shrimp, sole, squid, trout and whitefish.
  2. You may want to supplement your omega-3 fatty acid intake by fish oil capsules. It is important that you choose the more expensive higher potency products. A molecular distillation process that removes mercury, PCB and other heavy metals creates these higher potency products. This way you only get the enriched omega-3 fatty acids in pure form. EPA and DHA in one capsule should be in the 900 mg to 1000 mg range, not less. I take 2 capsules twice per day as a daily supplement. This helps you as indicated above to balance the omega-6 to omega-3 ratio, which cuts down any inflammatory process in you.

More good news about omega-3 fatty acids

Omega-3 fatty acids have multiple anti-inflammatory effects. This helps for treating arthritis, osteoporosis, preventing heart attacks and brain shrinkage. Even depression can be influenced positively when krill oil and fish oil are both taken at the same time. It is best to think about krill oil and omega-3 fatty acids (fish oil) as complementary marine oils that have multiple beneficial effects on the body.

Studies have shown that arthritis and osteoarthritis are helped by krill oil, but also by fish oil. Similarly, heart attacks and strokes are prevented with both krill oil and omega-3 fatty acids. It appears that both oils reduce inflammation in the arteries that is associated with high blood pressure, diabetes, obesity and the metabolic syndrome in obese people. C-reactive protein measuring inflammation was reduced by krill oil up to 30% compared to placebo within 30 days. Patients with arthritis had 20% and more reduction in stiffness and pain.

Krill oil is well absorbed into the brain and can prevent age-related brain shrinkage, preserve cognitive function and memory, prevent dementia and also possibly depression.

Other health conditions improve on both krill oil and omega-3 fatty acids like osteoporosis (in combination with vitamin K2, vitamin D3 and calcium), a weak immune system, diabetes, high triglyceride levels and cholesterol problems. Both marine oils prevent LDL cholesterol from being oxidized, which helps to prevent atheroma formation and hardening of the arteries. This prevents heart attacks and strokes.

Conclusion

In the past cod liver oil was given to children to prevent rickets. In the 1960’s Dale Alexander wrote a book called “Arthritis and Common Sense”. Since then medicine has been revolutionized in the late 1990’s by the idea that inflammation in the body is responsible for high blood pressure, diabetes, heart attacks, strokes, arthritis and even Alzheimer’s disease. It is in this area that omega-3 fatty acids are an important supplement as fish oil capsules and krill oil capsules. These supplements can be bought molecularly distilled to be free of mercury and other pollutants. The anti-inflammatory effect of omega-3 fatty acids is a powerful preventative for all these diseases mentioned. It no longer is a question, whether these supplements work. It has become a fact backed up by large studies including mortality statistics. Even the FDA has included seafood into their food recommendations. The key is to rebalance your omega-6 to omega-3 ratio and incorporate marine oils in your diet. Your body will thank you for it with a longer, healthier life.
