In life, many people think that the food, in which a lot of extra nutrients or drug ingredients are added, with certain effects, should actually be health products. They have their own applicable people and the use of the amount of contraindications, not everyone can eat. Cod liver oil Cod liver oil is a fatty oil extracted from the liver of sea fish, the main components of vitamin A and D, can help prevent rickets in infants and children, to maintain normal vision, which is completely different from the people’s understanding of “fish oil”. And vitamin A and D are fat-soluble vitamins, excessive intake can not be properly excreted through the urine, will be a burden on the liver and kidneys, so cod liver oil must be taken under the guidance of a doctor, suffering from urinary stones or weak people, should not take, so as not to aggravate the symptoms or poisoning. Energy drinks In general, energy drinks contain glucose, fructose and B vitamins in addition to taurine, lysine, caffeine, inositol and other ingredients. Caffeine can reduce human fatigue, but the most important feature of this central nervous system stimulant is that it is addictive, that is to say, one can may have a refreshing effect before, but if you drink it for a long time, you may need to increase the dose afterwards. Therefore, children and pregnant women should not consume it as it may affect their development. Healthy adults also need to be aware that although these drinks do contain some nutrients, it is not advisable to become dependent on them, especially not to use them instead of drinking water and using them to fight the “sleepyhead” for a long time. Hungry to eat, sleepy, tired to sleep, do not feel fatigue does not mean not fatigue. Long-term consumption of energy drinks “refreshment”, will overdraw the body, increase the cardiovascular burden, very undesirable. Nutrient gummies Common nutrient gummies are generally children’s health products, these nutrient gummies are gummy sugar, children eat easily cause airway blockage. Many of them contain calcium and vitamin D. In general, children with normal and reasonable diets do not need additional vitamin supplements, and many parents are always worried that their children do not have enough nutrients, so they give them to eat these nutrient supplements alone. The most important thing to know is that these nutrients can be toxic in excess, cause stones or affect the development of the child’s body, and bring health risks. Many people do not know what kind of body they are, so they take health care wine with aphrodisiac and other effects without permission. This is not only unaware of the fact that this is not health care, but also hurts the body. In fact, people with Yang or Yin deficiency and fire should not drink this kind of medicinal wine. In addition, it is not suitable for children, pregnant women and patients with cardiovascular diseases. It should also be reminded that the slimming plum sold online is claimed to be “a natural green food with plum as the carrier, extracting active ingredients from herbs such as romaine fruit and sunflower leaves, without any chemicals”. But in fact, this kind of product with weight loss effect should also belong to health care products. Therefore, before taking health products, patients should consult a doctor or pharmacist at a regular hospital and buy products with health product approval numbers. Health products are not a substitute for drugs, and if you suffer from a disease, you still need to go to a regular hospital for consultation and treatment, and under the guidance of a doctor, take medication for standard treatment.
