From carrots that can improve your eyesight to drinking milk, here are 20 tips on health that are actually just myths.
1. Milk is very good for adults’ body
This type of advertising is very well entrenched in people’s minds. Department of Agriculture from the United States promoted that drinking four glasses of milk per day has enough calcium and vitamin D for adults. Countless studies have yet to find a link between milk consumption and the low number of broken bones.
2. Organic food without pesticides is healthier
Organic food is not necessarily without pesticides nor healthier.
Farmers who grow organic products may use chemicals derived from natural products and in some cases are more harmful to the environment than synthetic ones. The level of both pesticides in organic food and in the non-organic is low and it does not have a negative effect when eating. Eating organic food does not bring a higher nutrient intake than non-organic food.
3. It is ok to eat food that you dropped on the floor if you pick it up in less than five seconds
Five seconds rule is not real, the bacteria can contaminate food in milliseconds.

4. Tryptophan chemical from turkey makes you sleepy

6. An apple a day keeps the doctor away!

7. Natural sugar, like honey, is healthier than processed sugar
A cereal bar that has honey instead of fructose is better for health.
The sugar from natural products such as fruits or products is the same: “researchers would be surprised to hear about the superiority of honey since there is no consensus of the biological effects of fructose or honey, ” said Professor Alan Levinovitz.
The problem is that synthetic products such as candies contain a dose of sugar too high.
8. Coffee stops the growth
Most investigations have not found any correlation between caffeine intake and bone development of children. For adults, drinking coffee can slightly limit the absorption of calcium, but the impact is so small that a spoonful of milk could offset the effect of a cup of coffee.

A letter cannot banish numerous studies, according to the National Institute of National Health. “The idea that refined sugar causes ADHD is very popular, but most research discredited this assertion”.
13. The blood turns blue when there is no oxygen
It is said that blood changes the color dark red when no longer carry oxygen, but the reason the color is blue it is because the blood is covered by several layers of tissue that changes its color.
14. People have five senses
