Life expectancy is a phenomenon on which many factors affect: environmental, behavioral, socio-demographic and dietary. It is believed that food helps to extend the life and prevent the appearance of deaths. However, scientists have proven: food - far from the main thing.
Modern cell aging theory
Cellular aging is a slow deterioration of features at the cellular level and body level. In total, on the theory of heiflica limit, limiting the number of cell division at the DNA level, there are three stages of cell aging:
1) Reducing the protein molecule associated with DNA replication
2) Reduced RNA synthesis and related proteins
3) Reducing the overall speed of protein synthesis
It is believed that aging is associated with the oxidation process. The theory of active forms of oxygen (AFC) assumes that free radicals cause damage at cellular and tissue levels. To recover after microtravum, the body synthesizes new cells, but due to the natural limitation of the division cycle over time, it ceases to cope. Then there are dangerous sickness: injuries of bones and joints, tumors and so on.

What scientists say
You can find many materials in which the chief council of authors - there are many vegetables, fruits and berries. However, blueberry cups are not enough to stop the powerful biological process. Healthy nutrition really affects our well-being, muscle strength, the speed of thinking and other factors, but cannot give us eternal life. The mitochondrial theory of radical aging (MFRTA), first proposed in the 1950s, as we noted above, explains the process of aging as a result of "oxidative stress". This theory is confirmed by some laboratory results, during which they noticed the dependence of the life expectancy of the animal from its metabolic rate. Studies also showed that an increase in the level of antioxidants in animals increases the duration of their lives.
The power limit was established as the main factor that slows down the production of active forms of oxygen (AFC), which are the most common free radicals in the body - it is they cause aging.
Spaces in theory
It would seem that you can stay in place and stop exploring this topic by accepting the theory for Axoma. However, scientists decided to explore the topic deeper: for the past recent years, they polled the MFRTA researchers and noticed that not all the provisions of the theory converge with practice. More detailed practical studies on animals suggest that the long-livers animals have a low level of damage to AFC simply because their organism by nature produces less free radicals. In fact, the entire connection of oxidative damage with longevity is destroyed.

What really affects aging
Although MFRTA was a useful and developed scientific hypothesis, soon the controversial provisions will be disproved by torture scientists. So leave expensive antioxidant additives on store shelves - you do not need them. As for the prescription of youth and vitality at older age, the main thing is good genes and regular exercise.
