The supplements in the diet of the elderly.

You define dietary supplements those products specifically designed to facilitate the intake of certain nutrients not found in foods by improper diet. In General, an appropriate and balanced diet can provide all the elements necessary to the maintenance of good health. For a particular lifestyle or for different reasons, there is growing custom to supplement the intake of certain nutrients in the diet through dietary supplements.

The supplements are recommended in cases where the body has no shortage of certain foods: thus do not have healing properties, but are used to supplement a normal diet, supplementing it. For their nutritional properties, must be taken within safe limits, taking into account the RDA (recommended dietary allowances), namely the recommendations of specialists. Elder living in today’s society, when welfare is widely spread, is typically better nourished than it had in a past not too far, but they are always numerous seniors who, for various reasons, practice an inadequate nutrition, not quantitatively as qualitatively: excessive use of refined foods precooked or heated foods, easy consumption, cheeses, meats, salt, low intake of fibre plants and therefore important for the intestinal transit, fish and liquids. Oral supplements (Oral Nutrition Supplement, ONS) may be useful in people malnourished or at risk of malnutrition in which supplementation (food fortification) using natural foods was found to be ineffective but they are still able to hire with natural foods at least half of their needs, when they experience an overall reduction of ingested foods evaluated in about half the amount of carbohydrates and proteins usually taken in the period leading up to the event in question. In recent years the range of ONS went widely expanding both in terms of composition bromatologica, both variants buds with better product palatability. This allowed a more targeted use nutritionally and favoured the patient compliance in taking hold. A recent meta-analysis, in fact, demonstrated statistically significantly increased body weight with reduced mortality in the elderly treated with oral supplements protein-calorie malnutrition.

But what are the causes?

Advanced age is particularly at risk of nutritional deficiencies, due to various factors, some of which are a result of aging:

• Senile Changes of digestive function, loss of appetite due to the reduction of taste and smell, the greater need for calcium and vitamin D, especially by women in menopause and post menopause, etc.
