Staying fit despite the years is possible thanks to foods that remove intracellular waste and stimulate regeneration.
As we age, changes occur in the body’s organs. Skin wrinkles and grey hair, the most obvious outward signs, are not harmful.
On the other hand, memory loss, weakening of the bones or hearing and vision impairments, which affect communication, significantly affect the quality of life.
How and why we age
But why do we age? How does this process work? Do some parts of the body age earlier than others? Two theories have more scientific support: free radicals and for telomere shortening.
Living beings are exposed to infections, radiation from the environment and a range of toxins (food additives, pesticides, plastics…). All these elements generate free radicals. On the other hand, the organism naturally produces this type of oxidative molecules as a result of its own metabolism and respiration.
Free radicals are dangerous because they attack cellular components, especially polyunsaturated acids in membranes, some proteins and genetic material, damaging them and altering their function.
The accumulation of damage in the genome causes shortening of telomeres (the outermost parts of DNA), which are already shortened at each cell replication. When the loss reaches 20% of the chromosomal chain, the cell is no longer able to reproduce and dies. Thus, both mechanisms are involved in cell ageing and senescence.
