Does an apple a day keep the doctor away?

Apples keep the doctor away for a day, spinach makes you strong, and carrots give you night vision. This is a rather silly statement that people have been making for a long time to determine children to eat right. But where do they come from and what is the truth in them?

There is no doubt that fruits and vegetables play an important role in maintaining our health and well-being. It is best to eat 2 servings of fruit a day (and follow the rule no more than 5 servings a day, add at least 3 servings of vegetables on top). However, the daily dose of fruit should not include apples. Turnbull does not know where that old fortune came from and, although it is certainly not harmful, the variety is good for the body. If you insist on seasonal products, you can mix and match, and if you are lucky enough to eat a delicious bunch that fell from a tree, you know how delicious seasonal food can be. (Hint: She likes a handful of blueberries for breakfast, raisins for lunch, and oranges to sweeten vegetable juices.) The World Health Organization (WHO) says it's beneficial to eat fruits and vegetables every day as it reduces risk of heart disease and some cancers.

Spinach makes you strong

Of course, this green leafy vegetable contains iron. But this myth, perpetuated by the notorious Popeye and his swallowing of cans, is actually based on some fluff. At that time, someone made a mistake in the nutritional analysis and put a comma in the wrong place in the spinach and it seemed to contain a lot more iron than there actually is! 

Iron alone will not make you strong. It gives the body more energy by producing red blood cells, makes the brain work better and strengthens immunity. Although meat is full of iron, one of the foods rich in iron is parsley. 

Carrots improve night vision.

There is a good story about which carrots were praised for helping to see in the dark.

In other words, yellow fruits and vegetables contain beta-carotene. The liver converts it into vitamin A, which keeps the skin healthy, suppresses the immune system and improves vision. This was the basis of the myth started by the RAF in World War II. They did not want to give up the new radar technology, so they said that human accuracy depends on all its roots. However, eating more carrots does not change your appearance if you have a deficiency.
