Nutrition and diet
The dietary imbalance (excess fat, sugar and alcohol), poor distribution of dietary inputs during the day (inadequate or nonexistent breakfast), an inadequate quantity of certain constituents (fibre, vitamins, minerals and trace elements) promote, by their recurrence, onset or worsening of diseases of greatest concern today: cardiovascular disease, obesity, diabetes, and probably some cancers. The more your food has been adapted to your needs during your life, the more it reflects on your health during the onset of old age. A healthy and balanced diet remains vital in the fight against aging. It will provide necessary inputs of fibre, minerals, vitamins, trace elements, essential fatty acids.
Three nutrients (carbohydrates, lipids and proteins) should be particularly monitored. First, the control of saturated animal fats, debilitating our arteries and leading to hypertension, atherosclerosis and stroke. Instead we must focus on polyunsaturated vegetable fats and those of marine origin, which are rich in omega 3. The omega 3 has a beneficial effect on sleep, immunity, brain regeneration and prevention of cardiovascular disease.
The other element is controlling the amount of sugar in our diet. Sugars are found in most consumer products, even in our water. Moreover, the food industry uses refined sugar without vitamins, which are just empty calories.
Regarding protein, plant proteins such as legumes and unrefined grains, low in saturated fat and rich in vitamins and fibre, must be promote.
Today, at least for part of humanity, food has increased in quantity but has lost in quality. Farming methods based on the use of chemical fertilizers, pesticides, etc.. ; methods of conservation by irradiation and drying; breeding methods (confined animal feeded hormones, steroids, antibiotics ...); methods of cooking which deprive our food of essential micronutrients (vitamins, minerals, trace elements, essential fatty acids). Food that produce "empty" calories, giving no energy. Those calories that contribute to overweight and developing heart disease.
The metabolism slows and caloric needs decline with age. Experts believe that after 50 years caloric requirements decrease by 10% every 10 years. That means that at 70 years a person needs 20% fewer calories, even less if she has become sedentary. If she keeps her intake, she gains weight and increases their risk of heart disease, diabetes and arthritis. As the body absorbs less of some nutrients, it must often increase the intake of certain nutrients: especially calcium to prevent osteoporosis, vitamin D that helps calcium absorption, vitamin B12 for red blood cells renew and maintenance of the neurological system, some minerals like zinc and potassium and folic acid to produce DNA and red blood cells.
Some studies suggest that vitamin deficiencies may still occur in the elderly who are feeding well. Some doctors therefore recommend daily supplements of vitamins and minerals, to ensure that the aging person continues to receive 100% of their recommended intake. However, it must also avoid supplements in high doses, unless on a specific recommendation by a doctor, because they often lead to metabolic imbalance.
We should drink six to eight glasses of fluid per day. Water is a nutrient as essential as vitamins and minerals. Water helps carry nutrients to cells and helps remove waste. In older people thirst is less felt, which can cause dehydration, confusion, headache, fatigue and other ailments.
Acid / base Plan
You feel tired, stressed, you have chronic pain and you have a few extra pounds. All your worries may have a single cause: the acidity of your body. This goes back to the rapidly changing dietary patterns, which are sometimes harmful to the body. At the beginning of humanity, people were hunters and gatherers, they had much exercise and ate mostly fruits and vegetables and lean meats. But the settlement was accompanied by the breeding and cultivation of plants. Moreover, because of the stresses to which they have been subjected, men have changed. There was therefore an acidification of the body. We measure the acidity with the pH or potential hydrogen. The more the body goes towards 1, the more he is acid, the more the body goes to 14, the more he is basic. The blood pH is 7.4 and does everything to remain as stable as possible.
Our bodies systems normally neutralize acids which help restore the acid-base balance of blood. It will thus make use of its reserves base to neutralize acids. Using, for example, the bone calcium to fight against acids. But if the imbalance is too large and chronic, fatigue, aching muscles and joints appears. In addition, it will have an effect on the bone stock, with a gradual softening, particularly in women. In general, acidification of the body will cause premature aging.
The daily stress for instance is responsible for acidification of the body, linked to levels of a hormone: cortisol. Lack of physical activity is also linked to acidification. But beware; too much exercise is harmful by producing acid. And of course, food is essential to change or restore the balance between acids and bases. The important thing is not to avoid acidifying foods and not eat the others, but to balance his meals.
No question of demonizing food: nothing is forbidden, the important thing is balance and compensation. Overall, the ideal is to put in his plate 70% alkaline foods and 30% acidic foods. And for the more refractory, food supplements rich in bases can counteract acidification.
