The elderly should be reasonable calcium

The proportion of calcium and phosphorus in the diet must be properly defined as calcium and phosphorus and a pair of “mysterious partners”. When the normal person maintains a proper ratio (2:1) of calcium and phosphorus in the plasma, “calcification” reactions can occur and calcium can be deposited. To the bones, the ability of the intestine to absorb these two elements can be brought into full play. The first few aquatic products with calcium-to-phosphorus ratio in this range, such as alfalfa, shrimp, kelp, seaweed, snail, and fish, should be eaten more.

Less salt, sugar, and more vinegar, the body's absorption and utilization of calcium is constrained by many factors, such as sodium and calcium reabsorption in the same way in the kidney, too much salt will inevitably increase sodium excretion, affect the recovery and reuse of calcium Sugar can inhibit intestinal absorption of calcium, while sugar is acidic foods, after eating more, the body to maintain acid-base balance, it is necessary to consume too much alkali, so that the consumption of calcium increased. Inadequate acidity of the gastrointestinal tract also affects the absorption of calcium, and proper vinegar is used when cooking foods, which can convert calcium in food into easily absorbed calcium acetate.

Do not forget to take calcium before going to bed. The calcium needs of the body are a continuous process. During the day, people can obtain calcium from the food they eat. However, when they go to sleep, they no longer eat, and they can only obtain it from the bones. The American professor Morris suggested that before going to bed, it is necessary to make up for a certain amount of calcium. The simplest and most effective method is to drink a glass of milk or two slices of calcium matrix before going to bed.

Elderly calcium supplements do not forget the absorption of calcium and phosphorus in sunbathing human body has a close relationship with vitamin D. Vitamin D can participate in the formation of a calcium-binding protein that is easily absorbed by calcium in combination with this protein. The 7-dehydrocholesterol in human skin can be transformed into vitamin D by ultraviolet irradiation in sunlight. Therefore, the elderly should often enter outdoor activities, more exposure to sunlight, in order to promote the absorption and utilization of calcium.
