In order to have a healthy body, many people can be described as "rushing to the front line of health care". They can't stop buying all kinds of supplements and strictly control their diet and exercise ... but sometimes they seem to be in health, and they may take a detour if they are not careful. Myth 1: I am keen on taking supplements for health. In recent years, high-grade tonics such as ginseng, velvet antler, ganoderma lucidum and cordyceps sinensis have begun to enter the homes of ordinary people and are also sought after by many health lovers. However, experts say that on the one hand, obesity, three highs, cardiovascular diseases and other diseases are inseparable from the usual diet, so people with these diseases do not need to be nourished; On the other hand, for some people with weak spleen and stomach, deficiency does not make up, and eating nourishing supplements can not only be digested and absorbed well, but also increase the burden on the stomach. Suggestion: For ordinary people, a balanced diet is enough to meet the nutritional needs of the body; In addition, if you want to make up, you should choose those foods with the same origin of medicine and food, such as yam, red dates, peanuts and so on. And be sure to distinguish your physique before eating.

Myth 2: Old people should take calcium tablets every day. When they get old, their absorption and utilization of calcium will decline, and the loss will be more serious during metabolism, so they are relatively prone to calcium deficiency. In order to avoid osteoporosis, many people are keen to take calcium tablets to supplement calcium, and even some people always feel that the more they supplement and absorb, the better they will be for their bones. But everything has gone too far. For people over 60 years old, it is recommended to take 1000 mg of calcium every day. Excessive calcium supplementation will not only strengthen bones, but also endanger health. For example, excessive calcium supplementation will obviously inhibit the absorption of iron, zinc, magnesium and phosphorus; It may also lead to an increase in blood calcium content, accelerate the formation of deposits in arteries, and increase the risk of vascular calcification and heart disease.

Whether you need to take calcium tablets, whether it is suitable for eating calcium tablets, and how much you need to eat, you'd better consult your doctor first, and don't blindly supplement it yourself. Myth 3: Oil-free and salt-free antihypertensive and lipid-lowering research found that long-term intake of too much salt will increase the risk of hypertension; Eating too much cooking oil can easily lead to high blood lipids and accelerate arteriosclerosis and thrombosis. Worried about these two points, some "health-conscious" people simply don't eat oil and salt and want to completely eliminate risks.

However, this practice is counterproductive: too much salt restriction will lead to insufficient sodium intake, imbalance of osmotic pressure inside and outside cells of the body, leading to water entering cells and inducing brain edema, ranging from conscious disturbance to increased heart rate, nausea and vomiting. Not eating cooking oil at all will not only lead to the lack of some fat-soluble vitamins (such as vitamins A, D, E and K), but also lead to the lack of essential fatty acids, which can stabilize blood pressure and blood sugar and can only be obtained from the outside world.
