How to deal with the various health care products on the market is the time to test our wisdom. When taking health care products that are considered effective, it is very necessary to confirm the amount of active ingredients in the drug. Some cheap products, although the pills are large, contain very little of the most important ingredients. Of course, the manufacturing process of the product must be completely trustworthy. In particular, don’t think that big companies that advertise on TV are fine. Unlike medical drugs that have been approved through rigorous testing, many health products on the market are counterfeit.
In particular, products that claim to be “effective against cancer” are questionable. Cancer patients have a hope of survival and hope to catch a life-saving straw, so they must judge calmly. These businesses are doing business by grasping the psychology of patients. For example, with glucosamine, the New England Journal of Medicine published definitive results on the use of glucosamine versus a placebo-controlled trial. Needless to say, the effect of placebo, glucosamine has no effect on the treatment of joint diseases such as knees.
Cod liver oil preparations are not out of date, and have been regarded as the latent power of excellent food supplements since ancient times.
Cod liver oil is liquid fat extracted from the liver of cod, shark and other fish. It is rich in vitamin A, vitamin D, minerals and other high-quality ingredients.
Whether it is meat, fish or vegetables, vitamins and minerals will be lost to a large extent during the heating process. Cod liver oil can supplement these nutrients for us. It can be said that cod liver oil has contributed to maintaining the health of modern people, and it is an ancient and fresh element. Even now, there are drops and tablets on the market, so you might want to try them.
Vitamin D may prevent cancer, but because it is fat-soluble, it is dangerous to take too much.
A research team from the Japanese National Cancer Research Center and Public Health Institute studied the relationship between the concentration of vitamins in the blood and the risk of cancer, and their research results were published in the British Medical Journal.
The survey began in 1990, accepting 8 prefectures in Japan (Iwate, Akita, Nagano, Ibaraki, Niigata, Kochi, Nagasaki, Okinawa) aged 40 to 69 A total of 34,000 male and female residents provided blood samples, and a continuous follow-up survey was carried out until 2009. About 4500 people were measured blood vitamin D concentration, and these people’s data were divided into four groups for the study. The results showed that the group with the lowest blood levels of vitamin D had a higher rate of cancer than the other groups.
Compared with the highest group, the lowest group had a lower incidence rate of many cancers except leukemia and thyroid cancer. The most notable of these is liver cancer. In addition, lung cancer, breast cancer, prostate cancer, lymphoma, gallbladder cancer, etc. also showed a low incidence rate. It can be seen that if the concentration of vitamin D in the blood can be maintained at a certain level, it is beneficial to the prevention of cancer.
Foods rich in vitamin D include mackerel, salmon, tuna and other fatty fish, as well as beef liver , Nuts, etc. However, the amount that people can ingest from food is very limited. Therefore, we can resort to health supplements. However, unlike water-soluble vitamin C and B vitamins, vitamin D is fat-soluble, so it cannot be excreted in urine. Excessive intake may cause hypercalcemia, kidney stones and other diseases, so pay more attention when using it.
However, vitamin D is different from water-soluble vitamin C and B vitamins. It is a fat-soluble substance, so it cannot be excreted in urine. Excessive intake may cause hypercalcemia, kidney stones and other diseases, so pay more attention when using it. The upper limit for vitamin D intake is 4000 IU per day. Therefore, when you are under 50 years old, you can take 1/10 of the upper limit, which is about 400IU per day, which should be used as a reference standard. People over the age of 50 can double their daily intake of 800IU. People over fifty, especially women, have an increased risk of developing osteoporosis. Vitamin D supplementation can promote calcium absorption.
