Longevity has to do with several factors. One of them is food and a healthy diet that prepares the body to live longer.
Aging is a continuous process that takes place throughout life. Therefore, our health is highly conditioned by our diet throughout our lives. Recent scientific research has shown a very close relationship between diet, diet, and aging.
Currently, people over 65 years of age represent more than 17% of the population in most so-called developed countries. In this context where there is and will be progressive aging of the population, and also considering that we want to live not only longer but also better, lifestyles are important. In this sense, nutrition is, without a doubt, a relevant aspect that can help us achieve years of life and maintain the quality of life at this stage.
The aforementioned studies have attempted to characterize dietary patterns associated with longevity and have focused on analyzing the dietary intake of, especially long-lived people. The results of these studies show that populations with an unusually high prevalence of centenarians tend to be very physically active, non-obese, and short-stature populations, which suggests a certain degree of caloric restriction (CR).
Long-term calorie restriction, without malnutrition, with adequate nutrient intake, could produce several metabolic adaptations, which reduce the risk of developing type 2 diabetes, cardiovascular disease, or cancer. However, it is possible that some of these beneficial effects are not due exclusively to caloric restriction, since there are studies that suggest that the degree and time of onset of CR, the time of food intake, and the composition of the Diet also play an important role in promoting health and longevity.
On the other hand, different epidemiological studies have found that diets based on vegetables, fish, olive oil, and lower consumption of processed foods are associated with better cardiovascular health, less cognitive deterioration, and greater longevity. Among these investigations is the eating pattern of the Mediterranean Diet.
In this sense, the macronutrient balance of diets, the number of carbohydrates, proteins, and fats, as well as the source and composition of amino acids in proteins can have a significant impact on longevity and metabolic health.
As neither calorie restriction nor macronutrient distribution alone explains, or at least so far, the differences or benefits found in the prevention of certain pathologies and in longevity, micronutrients and certain substances with antioxidant and/or role Anti-inflammatory drugs have also been the object of different studies to assess their potential in preventing the appearance of certain pathologies related to age or longevity.
A food pattern that meets the aforementioned characteristics is based on a frugal diet, with plant foods, olive oil as the main fat, rich in micronutrients. In addition, she opts for seasonal vegetables, aromatic herbs, and condiments and that includes a number of other aspects related to lifestyle such as active life, socializing meals, or promoting cooking from fresh products.
