Scientists have discovered 14 kinds of vitamins. If we do not get enough of the vitamins we need, we are at risk of developing a number of diseases. Scientists also find that it is better to eat vitamin-rich foods to prevent disease instead of eating them to cure a disease after it has developed. Which foods should be eaten to keep us healthy? Let us look at some important vitamins for these answers.
Vitamin A helps prevent skin and other tissues from becoming dry. People who do not get enough vitamin A cannot see well in darkness. Vitamin A is found in fish liver oil and the yellow part of eggs. Vitamin C is needed for strong bones and teeth. The body stores little vitamin C, so we must get it in foods such as fruits and tomatoes. Vitamin D prevents the children from getting rickets (佝偻病). In some countries, milk producers add vitamin D to milk so children will get enough. Vitamin K is needed for healthy blood. It thickens the blood around a cut to stop bleeding (流血).
Experts agree that everyone needs vitamins so that their bodies can operate normally. They also note that taking too much of some vitamins can be harmful and people should discuss what vitamins they need with their doctors.
If we do not get enough of the vitamins we need, we will______.
