Antioxidants - what are they, products and preparations with antioxidants

It is perhaps difficult to find a person who has not heard the word “antioxidants”. Various distributors of anti-aging potions and preparations are very fond of speculating with this term. And most often this word has a magical effect on the consumer. If you mention that a particular product contains antioxidants, then this increases interest in the product significantly, although no one can really explain what kind of “beast” this antioxidant is and why it is needed at all. For most, this definition is associated with incredible benefits, and therefore anything that contains antioxidants should be consumed frequently and in exorbitant quantities. Is this really so and what are the incredible benefits of these same antioxidants, and where can you get them?

Antioxidants: what are they?

Before defining this concept, we should consider a related one - the free radical theory of aging, in connection with which these same antioxidants have gained popularity, the benefits of which everyone knows today. This theory was first put forward by Denham Harman back in the 50s of the last century. The brief essence of the free radical theory of aging is that the cause of aging in the body is cell damage caused by free radicals. Free radicals are particles (atoms or molecules) that in their structure contain unpaired electrons at the outer electronic level. Free radicals cause damage to proteins, lipids, nucleic acids and other types of biomolecules. Damage to cells by free radicals leads to disorders in the body and, as a result, to aging and death. There is an assumption that mitochondria are involved in the formation of free radicals.

What are free radicals? Free radicals are reactive forms of oxygen, which are produced by mitochondria. How to neutralize the effect of free radicals on the body? First of all, you need to follow a low-calorie diet - we will consider this issue below. There is also a version that accelerated metabolism is the cause of oxidation of the body and the formation of free radicals. Versions have already been expressed more than once in scientific and pseudo-scientific circles that life expectancy depends on breathing rate. That is, the more often we breathe, the shorter our life expectancy. And if we consider this theory using the example of animals with different respiratory rates, then it fully justifies itself.

For example, a dog that breathes too frequently lives at best for a couple of decades, while a turtle that breathes about two per minute can live over 500 years. Thus, it can be assumed that the respiratory rate actually influences the rate of oxidation of the body, as a result of which it ages. It is also worth paying attention to professional athletes who, due to extreme physical exertion, regularly perform rapid breathing: their career most often ends by the age of 30, and by this time their health in most cases leaves much to be desired. It is possible that the reason for this is an inadequate frequency of respiratory cycles on a regular basis.

How can we neutralize the effect of free radicals on our body and prevent cell oxidation?

• First, change your breathing rate. If the theory is that accelerated metabolism, which occurs as a result of high breathing rates, leads to aging, then you should gradually accustom yourself to deeper breathing and thereby reduce its frequency. For this, there is a special breathing practice Apanasati Hinayana, as a result of which we gradually stretch our breathing and thereby slow down our metabolism.
• Secondly, the human internal antioxidant system should be launched. The human body has already developed a system for rejuvenation and restoration of damaged cells; you just need to adjust its functioning. The pineal gland in the human brain produces the most important hormone - melatonin, which has a powerful antioxidant effect. The function of the pineal gland is inhibited by an incorrect daily routine (primarily staying awake at night) and an unhealthy diet with a predominance of fatty, fried, flour, sweet, salty and the presence of animal foods in the diet. Inverted asanas will help improve the functioning of the pineal gland and the production of the hormone melatonin.
• Thirdly, you should eat natural foods that contain natural antioxidants.

Antioxidant Products

As already mentioned, to neutralize the effects of free radicals on our body, we should follow a low-calorie diet. Fresh vegetables and fruits saturate our body with inhibitors of free radical reactions - antioxidants. Antioxidants can be enzymatic, that is, produced by our body, and non-enzymatic, that is, coming from the outside. In principle, nature designed it so that each cell itself can destroy free radicals entering the body, but if the amount of these free radicals exceeds the norm, then enzymatic antioxidants become insufficient. In this case, non-enzymatic antioxidants, that is, those supplied with food, will come to the rescue. The main non-enzymatic antioxidants are:

• vitamin C,
• vitamin E,
• provitamin A,
• lycopene,
• flavin and flavonoids,
• tannins,
• anthocyanins.

Vitamin C, vitamin E and provitamin A are found in fresh fruits, and lycopene is found in tomatoes. Flavin and flavonoids are found in fresh vegetables, tannins are found in cocoa, coffee and tea, but given the negative consequences that these drinks have, it is better to exclude them, since there will be more harm than good. Anthocyanins are found in berries, mainly red ones.

Operating principle

This introduction will help you understand what antioxidants are and how they work.

In all living organisms, metabolic processes occur - metabolism, in which oxygen plays an important role. Thanks to it, oxidation occurs, during which fats, carbohydrates, proteins and other beneficial substances necessary for the healthy functioning of all body systems are absorbed.

Under the influence of unfavorable conditions during oxidation, free oxygen atoms or free radicals are sometimes left behind. They are aggressive and tend to attach themselves to other molecules. For this, they are ready to break important but weak connections, thereby causing harm to the body.

Antioxidants are molecules that suppress free radicals. They balance the oxidative process, create balance and are a powerful preventive measure against a number of serious diseases, including degenerative changes in the retina, arthritis, Parkinson’s disease and Alzheimer’s.

What foods contain antioxidants?

Antioxidants are found in the following foods: prunes, plums, rowan berries, currants, pomegranate, mangosteen, acai, sea buckthorn, blueberries, grapes, cranberries, chokeberries, black plums, raisins, blackberries, strawberries, kiwi, fresh apples with peel, tangerines, gooseberries , blueberries, grapefruit, raspberries, orange, cherry, cabbage, spinach, Brussels sprouts, fresh tomatoes, fresh cucumbers with peel, raw pumpkin, alfalfa sprouts, rose hips, broccoli, beets, red peppers, eggplant, fresh corn, fresh radishes, cabbage fresh white cabbage, raw potatoes, as well as some legumes: small red beans, regular red beans, artichokes, black beans, peas. Among the nuts: walnuts, hazelnuts, hazelnuts, pistachios.

It should, however, be recalled that no matter what benefits certain natural and fresh products provide, overeating and abusing them will not be beneficial. Any food that is consumed in excess is not adequately digested and becomes poisonous. You should also be careful about mixing different types of products - this leads to fermentation and rotting. Thus, fruits and foods high in protein are best consumed separately from the rest: they are not compatible with other types of foods, as well as with each other. Protein products can only be combined with low-starch vegetables, but they cannot be combined with vegetables that have a high starch content.

Summarize

• Adequate intake of antioxidants is essential for your body's health, although some studies suggest that supplementation in high doses may be harmful.
• The best strategy is to get your daily dose of antioxidants from healthy plant-based foods such as fruits and vegetables.
