Omega-3 and vitamin E: A powerful duet for heart health

I. Introduction: Heart as a center of life and risks of cardiovascular diseases

The heart is a tireless engine that provides the life of the whole organism. It constantly pumps blood, delivering oxygen and nutrients to each cell. Heart health is a key factor in general well -being and longevity. Unfortunately, cardiovascular diseases (SSZ) remain one of the leading causes of mortality around the world. Risk factors for the development of SSZ are diverse and include high blood pressure, high cholesterol, smoking, obesity, diabetes, improper nutrition and lack of physical activity.

Understanding the mechanisms underlying the development of the CVD, and the search for effective prevention and treatment strategies are priority tasks of modern medicine. In recent decades, scientific studies are increasingly paying attention to the role of certain nutrients, in particular, omega-3 fatty acids and vitamin E, in maintaining the health of the heart and the prevention of SVD.

II. Omega-3 fatty acids: unsaturated miracle workers

A. What is omega-3 fatty acids?

Omega-3 fatty acids is a class of polyunsaturated fatty acids that play an important role in maintaining human health. They relate to indispensable fatty acids, that is, the body cannot synthesize them on its own and should receive them from food or additives.

The main types of omega-3 fatty acids that are relevant to the health of the heart:

  1. Eicopentenic acid (EPA): EPA is mainly contained in fatty fish and has a strong anti -inflammatory effect.

  2. Dokosagexenoic acid (DHA): DHA is also contained in fatty fish and is an important component of cell membranes, especially in the brain and eyes.

  3. Alpha-linolenic acid (ALA): ALA is contained in plant sources, such as flaxseed, chia and walnuts. The body can convert Ala into EPA and DHA, but this process is not always effective.

B. Omega-3 action mechanisms in maintaining heart health

Omega-3 fatty acids have a multifaceted positive effect on the cardiovascular system:

  1. Reducing the level of triglycerides: Omega-3, especially EPA and DHA, effectively reduce the level of triglycerides in the blood. A high level of triglycerides is a risk factor for the development of SVD. Omega-3 affect the enzymes involved in the synthesis of triglycerides in the liver, reducing their production.

  2. Reduced blood pressure: Omega-3 can provide a moderate decline in blood pressure, especially in people with hypertension. The mechanism of this effect includes an improvement in the function of the endothelium (inner vascular membrane) and a decrease in the activity of the sympathetic nervous system.

  3. Improving the function of the endothelium: The endothelium plays an important role in the regulation of the tone of blood vessels, blood coagulation and inflammation. Omega-3 contribute to the production of nitrogen oxide (No), a powerful vasodilator that relaxes the vessels and improves blood flow.

  4. Anti -inflammatory action: Inflammation plays an important role in the development of atherosclerosis (the formation of plaques in the arteries). Omega-3 has anti-inflammatory properties, suppressing the production of pro-inflammatory cytokines and inflammation mediators. They also contribute to resolving inflammation, stimulating the production of resolvines and protectins.

  5. Antiarrhythmic action: Omega-3 can stabilize the electrical activity of the heart and reduce the risk of dangerous arrhythmias, such as atrial fibrillation and ventricular tachycardia.

  6. Reducing the risk of blood clots: Omega-3 can reduce platelet aggregation (bonding of platelets) and improve the rheological properties of blood, thereby reducing the risk of blood clots that can lead to myocardial infarction or stroke.

  7. Reducing the growth of atherosclerotic plaques: Studies show that omega-3 can slow down the progression of atherosclerosis, reducing the size and stability of atherosclerotic plaques.

C. sources of omega-3 fatty acids

  1. Fat fish: Salmon, mackerel, herring, tuna, sardines – excellent sources of EPA and DHA. It is recommended to consume fatty fish 2-3 times a week.

  2. Plant sources: Flaxseed, chia, walnuts contain ALA, which can be transformed into EPA and DHA, but this process is not always effective.

  3. Enriched products: Some products, such as eggs, milk and yogurt, can be enriched with omega-3.

  4. Supplements: Fish oil, krill oil and vegetarian algae additives are a good source of EPA and DHA, especially for those who do not use enough fat fish.

D. Recommendations for the reception of omega-3

The recommended daily dose of Omega-3 varies depending on individual needs and health status. To maintain the overall health of the heart, the American cardiological association (AHA) recommends using at least 500 mg EPA and DHA per day. People with a high level of triglycerides or other risk factors of the SCZ may need a higher dose, from 1000 to 4000 mg per day, under the supervision of a doctor.

E. Possible side effects and warnings

Reception of omega-3 fatty acids is usually safe, but in some cases side effects can occur, such as:

  1. Gastrointestinal disorders: Nausea, diarrhea, bloating.

  2. Fish taste: It can occur after taking fish oil.

  3. Increasing the risk of bleeding: Omega-3 can dilute blood, so people taking anticoagulants should be careful and consult a doctor.

  4. Interaction with drugs: Omega-3 can interact with some drugs such as warfarin.

III. Vitamin E: Powerful antioxidant to protect the heart

A. What is vitamin E?

Vitamin E is a group of fat -soluble compounds with powerful antioxidant properties. The most active form of vitamin E is alpha-tocopherol. Vitamin E plays an important role in protecting cells from damage by free radicals, which are unstable molecules formed in the process of normal metabolism and under the influence of external factors, such as environmental pollution and smoking.

B. Vitamin E action mechanisms in maintaining heart health

  1. Antioxidant Protection: Vitamin E protects lipids (fats) in the blood, such as LDL (low density lipoproteins, or “bad” cholesterol), from oxidation. Oxidized LDLs are more atherogenic, that is, they contribute to the formation of atherosclerotic plaques.

  2. Improving the function of the endothelium: Vitamin E can improve the function of the endothelium, protecting it from damage by free radicals and inflammation.

  3. Decreased platelet aggregation: Vitamin E can reduce platelet aggregation, thereby reducing the risk of blood clots.

  4. Anti -inflammatory action: Vitamin E has anti -inflammatory properties, suppressing the production of pro -inflammatory cytokines.

  5. Cardiomyopathy protection, induced chemotherapy: Some studies show that vitamin E can protect the heart from damage caused by some chemotherapeutic drugs.

C. Sources of vitamin E

  1. Vegetable oils: Sunflower, safflore, corn, olive oil.

  2. Nuts and seeds: Almonds, hazelnuts, sunflower seeds.

  3. Green sheet vegetables: Spinach, broccoli.

  4. Avocado.

  5. Enriched products: Some cereals and flakes for breakfast.

  6. Supplements: Vitamin E is available in the form of additives, usually in the form of alpha-tocopherol acetate.

D. Recommendations for taking vitamin E

The recommended daily dose of vitamin E for adults is 15 mg (22.4 IU). Most people get a sufficient amount of vitamin E from food. However, in some cases, for example, in case of violation of fat absorption, an additional intake of vitamin E may be required in the form of additives.

E. Possible side effects and warnings

Vitamin E intake in high doses can lead to side effects, such as:

  1. Increasing the risk of bleeding: Vitamin E can dilute blood, so people taking anticoagulants should be careful and consult a doctor.

  2. Gastrointestinal disorders: Nausea, diarrhea.

  3. Muscle weakness.

  4. Interaction with drugs: Vitamin E can interact with some drugs such as warfarin and statins.

IV. Synergic action omega-3 and vitamin E

The combination of omega-3 fatty acids and vitamin E can have a synergistic (mutual) effect on the health of the heart. Vitamin E, as a powerful antioxidant, can protect omega-3 fatty acids from oxidation in the body, increasing their effectiveness. In addition, both nutrients have anti-inflammatory properties and can enhance antioxidant protection of the cardiovascular system.

V. Clinical studies: evidence of effectiveness

Numerous clinical studies studied the effect of omega-3 fatty acids and vitamin E on the health of the heart.

A. Omega-3 fatty acids:

  1. Gissi-prevention Trial: This major study showed that taking omega-3 fatty acids reduces the risk of death from cardiovascular diseases in people who have suffered myocardial infarction.

  2. JELIS trial: This Japanese study showed that the addition of EPA to statins reduces the risk of developing large coronary events in people with a high level of cholesterol.

  3. REDUCE-IT trial: This study showed that taking a high dose of EPA (4 grams per day) significantly reduces the risk of cardiovascular events in people with a high level of triglycerides and the SSZs or a high risk of its development.

  4. The meta-analyzes of numerous studies have shown that taking omega-3 fatty acids can reduce blood pressure, triglycerides and risk of arrhythmias.

B. Vitamin E:

The results of clinical studies on the study of the effect of vitamin E on the health of the heart are contradictory.

  1. Some studies have shown that the intake of vitamin E can reduce the risk of developing CVDs in certain groups of the population, such as women in postmenopausa.

  2. However, other studies did not reveal the significant effect of vitamin E on the risk of the SVD, and in some cases even showed an increase in the risk of death from all causes when taking high doses of vitamin E.

  3. The ambiguity of the results can be associated with various factors, such as doses of vitamin E, the duration of the reception, the characteristics of the studied population and other related factors.

C. The combined action of omega-3 and vitamin E:

Research directly studying the combined effect of Omega-3 and vitamin E on the health of the heart is relatively few.

  1. Some studies have shown that the joint reception of Omega-3 and vitamin E can improve the function of the endothelium and reduce the level of inflammation.

  2. Other studies did not reveal significant advantages from the joint administration of Omega-3 and Vitamin E compared to the only Omega-3 technique.

VI. Practical recommendations for the inclusion of omega-3 and vitamin E in the diet

  1. Increase the consumption of fat fish: Try to eat fatty fish (salmon, mackerel, herring, tuna) 2-3 times a week. Prepare the fish steamed, bake or grill, avoiding deep frying.

  2. Add Omega-3 plant sources to the diet: Include linseed seeds, chia, walnuts and linseed oil in your diet. Add seeds and nuts to salads, yogurts and cereals.
