According to recent estimates, children born in the early twenty-first century have a life expectancy of around one hundred years.
The aging of the Italian and global population is under everyone's eyes; thanks to the progress of science and an overall improvement in the quality of life, we are witnessing a constant increase in the average age of individuals.
Aging actively and in self-sufficiency therefore represents the fundamental premise for enjoying this long period of life in serenity.
Some simple precautions, to be adopted from childhood, can help us face old age with serenity and vigor.
Importance of the ideal weight
On the tables of industrialized countries, food has never been as abundant as in recent decades. Despite this, the qualitative aspect of food is often insufficient to maintain the optimal efficiency of the precious human machine. It is in fact a high-calorie food, not very satiating and poor in nutritional principles such as mineral salts and vitamins.
This paradox is at the root of the growing rate of obesity, a serious problem that is spreading in a frightening and worrying way.
One of the fundamental prerequisites for extending and improving your life is to maintain your body weight in the normal range. This trick, not always easy to adopt, is able to prevent, by itself, a very long list of pathologies. Furthermore, according to the studies conducted with success on many laboratory animals, an overall reduction in caloric intake would seem to be one of the best ways to persist in the state of psychophysical efficiency that characterizes youth.
Without getting to malnutrition, which is an "aggravating factor of the aging process, it is important to cover the needs of all the essential nutrients (proteins, fats and carbohydrates but also, and above all, vitamins and minerals) without overdoing the calories.
Vitamins
On a qualitative level, the nutrients that are most frequently lacking in the diet of Westerners are precisely minerals such as calcium, iron and zinc, and some vitamins (A, E, D, Folate, B1, B2 and C). It is therefore essential to ensure a correct intake of foods rich in vitamins and minerals such as fruit, vegetables, good fats (vegetable oils with the exception of tropical ones) and whole foods with the diet. Some vitamins and in particular E, or tocopherol, have demonstrated very strong antioxidant properties capable of attenuating, on their own, the impact of aging

Antioxidants, Diet and Sport
To defend itself against free radicals, our body combines the antioxidants deriving from the diet with very effective endogenous systems. A relationship has been demonstrated between the efficiency of these mechanisms and the lifespan of many animal species. The best way to increase the power of these endogenous antioxidant systems is through regular physical activity. This healthy habit explains why physical exercise makes people who practice it regularly appear more beautiful and younger. Sport also contributes to building a winning mentality and improving the mind-body relationship. Psychological crises caused by the inability to react. in a strong way to some unpleasant life events, they contribute to accelerate the physical decay of the organism.
Sport is also the best way to establish a positive hormonal picture in a completely natural way.
There are several theories, very popular in the States and lately also in our country, which portray hormone replacement therapy as the best method to win the fight against premature aging.
The production and secretion of the hormones on which this therapy is based (GH, testosterone and its precursor DHEA), is in fact significantly higher in subjects who practice an active life and maintain their weight within the norm.
Diabetes and Cholesterol
One of the most dangerous allies of aging is hyperglycemia, a condition typically associated with diabetes. We know that in most cases there is a genetic predisposition to the disease and that this is heavily influenced by the person's lifestyle (diet too high in sugar and reduced physical activity).
The fibers contained in fruit, vegetables and whole foods have a long list of beneficial factors including: stabilizing effect on blood sugar, increase in the sense of satiety, cholesterol-lowering action, prevention of overweight and obesity, improvement of the functionality of the gastrointestinal tract and reduction the incidence of some cancers.
Tumors
Risk factors in the diet
Esophagus tumor
Abuse of wine, beer and especially spirits;
deficiency of vitamin C, iron, zinc (lack of fresh fruit and vegetables); Nitrites and nitrates of preserved meats; frequent consumption of very hot food
Stomach Cancer
Nitrates and especially the nitrites contained in sausages, dried and smoked foods; see the dedicated article: nitrites and nitrates
Colorectal cancer
Excessive consumption of preserved meats, red meat, trans and hydrogenated fats, very salty foods; calcium supplements (relationship uncertain) and / or lack of fiber in the diet
Pancreatic cancer
Excess of alcohol, Excessive consumption of red meat
Water and Hydration
In the elderly, but also in many adults and very young people, dehydration is an often underestimated problem.
The decrease in the stimulus of thirst linked to aging, associated with a diet that too often replaces water with alcohol and sugary drinks, is responsible for a reduction in protein synthesis and an increase in adipose tissue. This worsening of body composition opens the doors to obesity and decreases physical and mental efficiency.
We should therefore strive to sip water throughout the day, even in the absence of thirst.
