For vitamins, not only foreigners favor, the Chinese often love it, and they eat it every day as a good supplement. However, a number of studies have found that even supplements are not suitable for everyone. The British "Daily Mail" published an article on September 17, summarizing "the supplements that different diseases should avoid" and ringing alarm bells for the majority of patients.
1. Psoriasis: Avoiding Vitamin A
Traditional retinoids of psoriasis, a derivative of vitamin A, are stored in the liver after entering the body. Overdose (more than 0.7 mg per day for men and more than 0.6 mg per day for women) produces toxins in the body, leading to conjunctivitis, hair loss and Skin disease worsened.
2, heart disease: Do not add vitamin E and potassium
A 7-year, large-scale study involving 10,000 patients with heart disease found at McMaster University in Canada found that patients with heart disease were given a large dose of vitamin E (400 IU per day, equivalent to 363 mg), and heart failure and after onset Hospitalization risks increase by 13% and 20% respectively. Excessive potassium (more than 3,500 mg daily) increases the risk of heart palpitations and arrhythmias.
3, Diabetes: Avoid vitamin B3
A large number of vitamin B3 supplements (more than 17 mg and 13 mg per day for men and women, respectively) in diabetics can lead to elevated blood glucose. The larger the dose, the more serious the blood sugar problem.
4. Osteoporosis: Avoid Vitamin A and Phosphorus
Phosphorus levels in the blood are too high (additions of more than 1000 mg/day) can lead to loss of bone calcium and increase the risk of osteoporosis. The British Health Guide recommends no more than 250 mg of phosphorus per day. High-dose vitamin A supplementation is closely related to the decrease in bone mineral density. Daily supplementation of more than 1.5 mg of vitamin A increases the risk of decreased bone density by 6% to 14%. At present, the recommended amounts of vitamin A for men and women are 0.7 mg and 0.6 mg respectively.
5, gastric ulcer: avoid vitamin A
The study found that taking vitamin A supplements at the same time as taking medications for gastric ulcers severely impairs the efficacy of the latter.
In addition to vitamins, it is best not to supplement calcium in patients with kidney disease and prostate cancer.
The two common causes of kidney disease are hypertension and diabetes. Calcium supplementation of more than 700 mg per day (recommended daily) will cause calcium build-up in the kidneys, and long-term calcium supplementation will lead to kidney stones.
At the same time, the Wake Forest Baptist Medical Research Center found that the loss of bone minerals is more serious in prostate cancer patients who are supplemented with 500-1000 mg of calcium per day. Exercise is an effective way to increase bone strength.
