Chronic Inflammation Can Cause Many Diseases

We knew since the mid 1990’s that chronic inflammation can cause many diseases. Among these are cancer, hardening of the arteries (atherosclerosis), arthritis, dementia (Alzheimer’s disease), frailty and other degenerative disorders. LifeExtension reviewed this topic in 2019.

Older people often accumulate chronic inflammation, which associates with the aging process. Persistent pain is one of the symptoms that chronic inflammation can cause.

Doctors use tests like the C-reactive protein, hemoglobin A1C, homocysteine and the erythrocyte sedimentation rate to measure chronic inflammation.

When the doctor diagnoses chronic inflammation, it is important to find ways to inhibit it and finally resolve it. Curcumin, ginger and non-steroidal anti-inflammatories are examples of measures that help inhibit inflammation. But it is only lately that scientists have found specialized pro-resolving mediators (SPM) that help to resolve chronic inflammation. They are polyunsaturated fatty acids, which health food stores offer as supplements.

Specialized pro-resolving mediators (SPM)

Researchers isolated several pro-resolving mediators that are metabolites of omega-3 fatty acids. This link discusses an experiment where researchers obtained synovial fluid from arthritis patients who took omega-3 fatty acids. They compared this to synovial fluid from volunteers who also took omega-3 fatty acid supplements. Within 4 weeks there was a big difference for the arthritis patients with higher levels of E- and D-series SPMs in synovial fluid and plasma. Dr. Silverman reviewed the action of SPMs here. He points out that they can be taken as supplements and that they are safe, because they do not have any side effects. Conditions such as asthma, irritable bowel syndrome and various musculoskeletal conditions with chronic inflammation respond very well to SPM supplements. Omega-3 fatty acid supplements (EPA) metabolize into the E-series resolvins.  On the other hand, Krill oil with Docosahexaenoic acid (DHA) metabolizes into protectins, maresins and the D-series resolvins.

Three vital tasks of pro-resolving mediators

SPMs fulfill three vital tasks, called remove, restore and renew.  First, they activate macrophages, which remove dead cells and cellular debris as a result of chronic inflammation. Second, they restore the healthy balance of inflammatory compounds and anti-inflammatory substances. Third, SPMs help renew tissues that were damaged by chronic inflammation.

Some examples where SPM’s were helpful resolving inflammation in health conditions

  • Alzheimer’s disease patients had reduced SPMs in cerebrospinal fluid of living patients and in the hippocampus of corpses who had Alzheimer’s disease.
  • A research group showed that defective SPM resolution can be responsible for missing resolution of atheromatous plaques in arteries. This leads to more and more hardening of arteries until a heart attack or stroke occurs.
  • With obesity or metabolic syndrome insulin resistance develops. Researchers found that certain SPM’s are missing in obesity, which causes chronic inflammation. However, they also found that precursors of SPMs such as 17-hydroxydocosahexaenoic acid (17-HDHA) can serve as a novel treatment agent to treat obesity-related complications.

Newer studies about SPMs

  • 62 patients with knee osteoarthritis had the precursor of resolvins, 17-HDHA tested in the blood. Compared to controls with no arthritis the 17-HDHA level in the arthritis patients was low. When levels of 17-HDHA were high, there was no pain in osteoarthritis patients.
  • Chronic periodontitis is a chronic inflammatory condition in the mouth. In a rabbit model this condition was cured with resolvin E1 derived from omega-3 fatty acids.
  • Delayed wound healing is typical for type 2 diabetes. In a mouse model with diabetic mice researchers inflicted skin wounds on mice. Subsequently they showed that with resolvins mice wounds healed much faster than in control mice.
  • Chronic kidney failure, liver impairment, diabetes, obesity and coronary heart disease showed abnormalities in the SPM system in humans. Potentially they will be healed with the help of resolvins or their precursors, which includes the omega-3 fatty acids EPA and DHA.

Chronic Inflammation Can Cause Many Diseases

Conclusion

New compounds have been detected that derive from the omega-3 fatty acids EPA and DHA. They have the name specialized pro-resolving mediators (SPM). Included are the resolvins D1 and D2, the resolvins E1, E2 and E3 as well as the precursors 18-hydroxyeicosapentaenoic acid (18-HEPE) and 17-hydroxydocosahexaenoic acid (17-HDHA). The function of these compounds is to stimulate macrophages to clean up areas of chronic inflammation and remove cell debris and injured cells that cannot survive. While anti-inflammatories like ginger and curcumin only tone down the inflammation, SPMs help to resolve chronic inflammation. Various chronic clinical conditions were identified as being due to chronic inflammation. Chronic kidney failure, liver impairment, diabetes, obesity and coronary heart disease showed abnormalities in the SPM system. We may soon see alternative approaches treating these conditions with specialized pro-resolving mediators.

The Quality of Food is Important

Many authors wrote books about food; the quality of food is important. Recently I came across a book review regarding the book “The Way We Eat Now” by Bee Wilson. In the March 2020 edition of the health magazine “LifeExtension” Laurie Mathena interviewed Bee Wilson about her book.

Bee Wilson explained that there is a distinct history about the production of food throughout the centuries. She described 5 phases.

  1. During the hunter/gatherer time people were eating a low-fat diet with berries, wild greens and wild animals.
  2. Stage two began around 20,000 BC. It was the agricultural age with a switch to cereals. At that time the population experienced rapid growth.

More stages

  1. Only a couple of centuries ago, agriculture made progress with crop rotation and by adding fertilizers. This led to a more varied diet. People ate more vegetables, less starchy food and animal protein.
  2. After the Second World War there was a major food transition. Processed food was introduced. People started eating more fat, meat, sugar and a lot less fiber. We are now experiencing a phenomenon that we are simultaneously overfed, but undernourished. We get too many calories, but our diet is poor in nutrients. This type of diet causes obesity and degenerative type illnesses.
  3. Stage 5 involves people abandoning junk food and eating more vegetables and fruit again. The more knowledgeable people are about the link between a good diet and health, the healthier people eat. This stage requires governments and other organizations to do their part in assisting people to make that food transition.

Food labeling changes in Chile

Here is one example of how governments can make a difference. This happened in Chile. Chile used to have the highest consumption of sugary beverages in the world. Prior to 2016 the average consumer in Chile bought more than 50% of the food as ultra-processed. This resulted in Chile having the second highest obesity rate after Mexico. The government of Chile decided in 2014 to introduce very simple labels for every food item. The government of Chile demanded that all the foods with too much sugar, high saturated fat, food high in salt and high in calories had proper labels. These labels are simple, hexagonal warning labels.

Warning labels

For instance, if a food product had too much salt in it, it would say in the hexagonal label: “Warning: high in salt”. As the labels had the effect of lowering sales, the food companies reformulated their products very quickly to stay under the threshold triggering the food warning. In 2016 Chile also decided to tax unhealthy foods higher. The government taxed sugar-sweetened colas with an 18% extra tax. Schools had to abandon junk foods sales.

Quality of food

When you start cutting out junk food and other processed foods, the quality of your food intake is improving. Eat more vegetables, and fruit. Eat wild salmon, which provides omega-3 fatty acids. Do not consume vegetable oils like soybean oil, canola oil, safflower oil, corn oil and grape-seed oil. They all contain omega-6 fatty acids. Omega-6 fatty acids are essential fatty acids and they convert mainly into energy. But the problem is that our western diet contains too many omega-6 fatty acids. Omega-6 fatty acids can convert 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.

The omega-6 to omega-3 ratio is important

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. No wonder people get sick with degenerative diseases.

Brain health maintained by eating enough omega-3 fatty acids

Here is a study that 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, preventing Alzheimer’s disease.

Cook your own food, do not eat out frequently

When you cook your own food, you can choose the right foods as you shop. Stay away from the “dirty dozen”, which is poisoned with insecticides, herbicides or pesticides. Instead you can buy organic foods that have not been sprayed with toxic substances. When you eat out, you have no choice about what you eat. Food in restaurants also contains food preservatives that are not labeled in North America, but that would be labeled in restaurant menus in Europe. In addition, food in restaurants often contains too much salt, too much sugar and the wrong oils. Omega-6 fatty acids are much cheaper than olive oil, and as a result this is what the chef uses.

Transition from stage 4 to stage 5

When you want to transition from stage 4 to stage 5 regarding your food composition you are swimming against the stream of establishment. At this point you are more or less alone when you want to abandon French fries, processed food bars, hamburgers and sugary soft drinks. But the more you eat at home, the more you take out your lunch box with food prepared at home, the more you are winning the war against convenience foods. It is what you put into your mouth, which is the fuel for your body. Don’t compromise regarding the quality of your food!

The Quality of Food is Important

The Quality of Food is Important

Conclusion

The quality of food is important. We have been inundated by ads from the food industry that we should eat fast foods (hamburgers, French fries), processed foods like power bars and drink sugary drinks. We have met the entire lineup on television! But it is best to buy basic foods and prepare all your food from scratch. Be careful that you avoid the “dirty dozen” foods. If you want to eat these, buy the organic food versions. This way you avoid pesticides and other poisons. Stick to extra virgin olive oil as a fat source and avoid vegetable oils. Soybean oil, canola oil, safflower oil, corn oil and grape-seed oil contain a lot of omega-6 fatty oils.

Inflammation caused by vegetable oils

These cause inflammation in your blood vessels and joints. The end result are heart attacks, strokes and arthritis. I also eat a lot of wild salmon and other seafoods, a great source of omega-3 fatty acids. In addition, I take two capsules of molecularly distilled fish oil in the morning and at night. Eat more vegetables and fruit. You are now paying attention to the fact that the quality of food is important.

Eat Right for a Long Life

Dr. Felice Gersh gave a talk at a conference in Las Vegas stressing the importance to eat right for a long life. This was at the 27th Annual World Congress on Anti-Aging Medicine in Las Vegas from Dec. 13 to 15th, 2019. The actual title of her presentation was “Nutrition for Longevity”.
Dr. Gersh has a fellowship in Integrative Medicine at the University of Arizona School of Medicine.

In the first place she pointed out that an anti-inflammatory diet consists of vegetables, fruits, nuts, whole grains, healthy oils like olive oil and fish. This is a modified Mediterranean diet. On the other hand, with a pro-inflammatory diet or Western diet, you eat high fat, cholesterol, lots of protein from red beef, high sugar, excessive salt and a lot of processed and fast-food.

Prevention of diseases

It is important to realize that for prevention of cardiovascular disease, cancer and degenerative diseases you need to eat fruits and vegetables, which contain important phytochemicals. They contain a wide variety of molecules, like carotenoids, vitamins and polyphenols. Another key point is that cruciferous vegetables (broccoli, Brussels sprouts, and kale) contain glucosinolates, which are sulfur-containing compounds. They protect you from cancer.

Vitamins and magnesium

It must be remembered that in order to strengthen the immune system and prevent hardening of the arteries (atherosclerosis) we need the following: omega-3 and omega-6 fatty acids, the enzyme Co-Q10, vitamin A, B complex, C, D, E, carotenoids, phytosterols, stilbenes and flavonoids. Another key point is that magnesium is extremely important. Many of our dietary habits have reduced magnesium intake to a minimum. Our soils are depleted of magnesium, it is no longer in drinking water, and it is absent in processed foods. However, magnesium is involved as a co-factor in more than 700 enzymatic reactions in our bodies. Magnesium is involved in heart contractions, is important to maintain our blood pressure and is important for glycemic control. It is also important for bone development and for DNA and RNA synthesis. Magnesium binds serotonin and dopamine to their receptors and plays a role in many more body functions.

Brassica vegetables

This group of vegetables consists of broccoli, cauliflower, green cabbage and Brussels sprouts. Notably, they have long been recognized to lower the risk of many cancers. The first thing to remember is that the active ingredients in them are glucosinolates and isothiocyanates. Certainly, food preparation has a lot of influence on maintaining beneficial substances in the brassica vegetables. To emphasize, finely shredded vegetables had a marked decline of their glucosinolate levels by 75% within only 6 hours. On the negative side, microwave cooking destroys 74% of glucosinolates, but on the positive side, storage in room air preserves almost all of the glucosinolates for 1 week. In addition, stir frying brassica also preserves the glucosinolates. This reference points out how fruit and vegetables can contribute to cancer prevention.

The gut microbiome

The Western diet leads to a change in the gut flora with Gram-negative bacteria taking over the healthy gut flora and disrupting the intestinal barrier. To emphasize, this result is called endotoxemia. Part of this is increased serum endotoxin, which mainly consists of lipopolysaccharides. Indeed, it causes gut inflammation and a breakdown of the gut barrier. When this happens, autoimmune antibodies are produced. To put it another way, the Western diet undermines your health. In a word, high fat foods and added sugars (refined carbohydrates) lead to increased Gram-negative bacteria and the disruption of the intestinal barrier.

An unhealthy diet causes disease

In the long run this causes autoimmune diseases, leads to higher heart attack rates and to diabetes. Healthy gut bacteria in fact help to digest fibre, which leads to three short-chain fatty acids: butyrate, acetate and propionate. For the most part, they are important as energy source, affect cardiometabolic health and appetite. On balance, butyrate also helps to maintain the blood brain barrier.

Importance of fiber

Higher fiber content in food leads to less cardiovascular disease, has positive effects on obesity and the metabolic syndrome. Fiber changes the microbiome in the gut, leads to less gut permeability and more short-chain fatty acids production.

The best diet

  • 60% to 70% complex carbohydrates are the foundation of a healthy diet. It consists of vegetables, green leafy and root vegetables, beans, legumes, whole grains and fruit.
  • Eat healthy fats from nuts, olives, seeds, krill or fish oil. Limit fat intake to 18 to 28% of your daily calorie intake. Avoid hydrogenated fats. Limit your saturated fatty acid intake. 85% chocolate is OK. Otherwise consume olive oil and omega-3 fatty acid containing foods (from seafood and fish).
  • Add about 12% of the daily calorie consumption as protein per day. Choose fish, seafood, lean cuts of chicken, only the occasional red meat (organic or grass-fed meat)
  • Eat lots of fiber, eat organic and minimally processed food. Limit sugar, fat and salt. Avoid antibiotics from the agricultural industry, sweeteners, gluten and excessive alcohol intake. Take a daily probiotic and eat probiotic food. Eat three meals a day, a big breakfast, a moderately-sized lunch and a small dinner. A fasting mimicking diet once per month for 5 days activates your longevity genes.
Eat Right for a Long Life

Eat Right for a Long Life

Conclusion

Dr. Felice Gersh gave a talk at a conference in Las Vegas. This was at the 27th Annual World Congress on Anti-Aging Medicine in Las Vegas from Dec. 13 to 15th, 2019. She said that we need to eat right for a long life. She gave a thorough outline of what to eat and what not to eat. It is important to note that she suggested to cut out additional refined sugar and processed food. The bacteria in the gut must be normal, or the gut barrier breaks down. This failure can cause autoimmune diseases. Eating lots of vegetables and fruit as well as fiber will help to keep your gut bacteria normal.

What foods to eat

A Mediterranean type diet gives you the right foods that you need for your health. Avoid the Standard American diet as it is unhealthy and kills the good gut bacteria. Brassica vegetables like broccoli, cauliflower, green cabbage and Brussels sprouts prevent the development of many cancers. Eat three meals a day, a big breakfast, a moderately-sized lunch and a small dinner. This fits best into the diurnal rhythm of your gut bacteria.

Benefits Of Eating Nuts

You hear from time to time that there are benefits of eating nuts. But you don’t often see more details about it. I came across an article entitled “Nut lovers rejoice: Your favorite snack protects your heart”. It stressed that nuts prevent heart attacks. I will review some of this information here, but also touch on other aspects.

What nuts contain

Nuts contain fiber, unsaturated fatty acids, protein, vitamin E, folate and many minerals (zinc, potassium, magnesium). These ingredients have their own positive effects on your metabolism. For instance the fiber will lower cholesterol and triglycerides in your blood, which are risk factors for heart attacks. Vitamin E is a powerful antioxidant. Here is a review that shows why eating nuts makes a difference for your health. Despite all of the good that nuts do, you need to keep an eye at the overall quantity of nuts you eat. Nuts can contain up to 80% as oil, even though they are good oils. But the extra calories associated with the oil can make you gain some weight. When you add nuts to your diet you need to subtract some of the lesser quality saturated fats, so that your overall calorie balance does not change.

How do we know that nuts are healthy?

A British study from 2016 did a meta-analysis of people who ate nuts versus people who did not include nuts in their diet. 10 studies showed that eating nuts reduced mortality from all causes by 19%. In 5 studies where cardiovascular mortality was measured, a reduction of 27% was noticeable. Congestive heart disease in 3 studies showed a reduction by 34% when the patients consumed nuts. Stroke mortality was 17% less, as 3 studies showed. This is just an example of a few studies that show how effective supplementation of your diet by a few nuts here and there can be on the general mortality. It especially applies to mortality which is due to heart disease and strokes. Other effects of nut consumption are the reduction of atrial fibrillation, congestive heart failure and abdominal aneurysm (each by 15 to 20%).

Allergic reactions to nuts

A small percentage of people are allergic to various nuts. Nuts can cause a severe asthma attack, if the person has been sensitized to them in the past. They can cause angioneurotic edema in a small portion of people who may have inherited this condition. Tree nut allergies can cause anaphylaxis as is explained in this link.

The right dosage of nuts

This Australian website says that 30 grams of nuts, which is a handful of them would be the right dose per day. This is about 1 ounce per day. By including a variety of nuts your nutritional content will equal out. Some nuts have more calcium (almonds); others have more plant sterols (pistachios) or more fiber (pecans).

How bias can get introduced into medical literature

The Karolinska institute in Sweden analyzed the lifestyle and behavior pattern of nut lovers. Nut lovers were also into other healthy lifestyles: they smoked less than non-nut lovers. Nut lovers were leaner, physically more active and drank less alcohol.

They also ate more fruit and vegetables. Nut-lovers’ blood pressure was lower than the blood pressure of non-nut lovers. And people who consumed nuts on average had better education. Some of these lifestyle patterns can also protect the heart and contribute to less strokes. The researcher must be vigilant to control for the other lifestyle patterns except for the difference in the nut consumption when looking for the effect of nut consumption. If this is not done, there could be confounding, which introduces a bias into the final results.

Combine nut supplements and adopt a healthy lifestyle

This said, you know now about the results of good research. It is best to not be concerned about biases any more. For the average consumer it is important to apply what we know: use nuts regularly (about 30 grams per day, which is a handful). But it would not be a bad idea to adopt some of the other healthy lifestyles that nut eaters tend to have. In other words, exercise regularly, don’t smoke, cut out sugar, drink less alcohol and eat fruit and vegetables regularly. This way you will amplify the health promoting effect of the nut supplements.

Benefits Of Eating Nuts

Benefits Of Eating Nuts

Conclusion

We learnt that nut consumption is healthy. Only a small number of people who are allergic to nuts have to avoid them. The majority of people benefit from incorporating a small amount of nuts into their diet. Research has shown that it lowers mortality in general, lowers cardiovascular mortality and mortality from congestive heart disease. Eating nuts also reduced stroke mortality and lowers the risk of atrial fibrillation. When research is done, confounding factors like healthy lifestyles have to be controlled. But when an individual wants to reduce health risks, it does not harm to use healthy lifestyle factors along with nuts to reduce any risk. It will amplify the healthy effects of eating nuts.

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 memranes. 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.

Healthy Oils For A Healthy Body

Healthy Oils For A Healthy Body

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.
