C
Now, we know that if we do not get enough vitamins, we are at the risk of devel?oping a number of diseases. As a result, vita?min supplements(补品)，though expensive, are popular with people who worry that they are not get?ting enough vitamins from the foods they eat. But contrary to what many people think,medical experts have found lit?tle evidence that most supplements do anything to improve health or protect against diseases.
In fact, medical experts warn that taking too many of some vitamins can be harmful. For example*too much vita?min E can cause bleeding. People should discuss what vita?mins they take with their doctors, as some vitamins can produce harmful side effects when mixed with medicines.
Experts, however, do say that sometimes vitamins can help prevent diseases. People who know they lack a particular vitamin should take vitamin supplements. Some older adults, for example, may not have enough vitamin twelve. This is because, as people get older, their body loses its ability to take it from foods. Also, people who spend much time in?side may need some extra vitamin D as the skin makes this vitamin from sunlight.
Different vitamins are found in different foods. Vita?min A is found in fish liver oil. It's also in the yellow part of eggs. Sweet potatoes, carrots and other darkly coloured fruit and vegetables contain substances that the body can change into vitamin A. Vitamin B-twelve is found in green leafy vegetables and other foods, like fruit. Vitamin K can be found in pork products.
In fact, for most people, a balanced diet can ensure enough vitamins our bodies need. So,it is important for us to eat a mixture of foods every day to ensure that we get enough vitamins.
