7 myths of health, refuted by modern scholars
Pseudo-scientific myths are not so easy to move real events. We told you to do 10 thousand steps a day, buy gluten-free foods and drink just half an hour after eating. However, all these beliefs are not confirmed by science.
1. Gluten is harmful to health
The researchers compared more than 650 gluten-free products with their traditional counterparts and found that the first contains more calories, sugar, fat and less protein. There are people who have to eat gluten free because they have allergies or are sick of celiac disease and that gluten consumption can harm the small intestine (approximately 1 in 100 people in the world). For healthy people that limit the amount of whole grains in the diet it can increase the risk of heart disease.
2. Activated carbon will help with a hangover
The symptoms of a hangover derive from the fact that alcohol in the liver becomes toxic acetaldehyde, which then enters the blood. Activated carbon binds to the toxins of the human body through adsorption and helps with rapid excretion through the intestine, but it is only effective in the first hours after poisoning. To associate something in the stomach in the morning – a meaningless idea.
To relieve headache, you can drink non-steroidal anti-inflammatory drugs such as ibuprofen, diclofenac and naproxen (but not paracetamol: it is not combined with alcohol), nor does the abundance of water.
3. There are negative caloric foods
Celery, grapefruit, broccoli, tomatoes and cucumbers are called negative caloric foods, but there is no scientific evidence confirming this idea. Although they are low calorie foods (7 to 30 kcal per 100 g), to be able to digest, the body requires even less energy. This is because they contain a lot of water and fiber, the processing of which the body spends a little effort.
4. You can not drink during meals
Drunk water during meals helps to wash particles eaten in the esophagus and stomach, breaks large amounts of food and also facilitates the access of acids and enzymes to food particles. It dilutes the enzymes of gastric juice, but it does not interfere with the stomach. The stomach can regulate the composition of gastric juice and a glass of drunk water during a meal, it only helps this process.
5. Bar soap transmits bacteria
Soap does not transmit infection. Even the hands of a person with the Ebola virus were washed, a bar of soap will remain safe. Scientists have conducted an experiment: they specifically infect bacterial hands, wash their hands and give the same piece of soap to the next participant in the experiment. As a result of the bacteria in the hands of a party they found.
6. Threat of antiperspirants
Antiperspirants work due to the fact that aluminum salts clog the pores from which it sweats. In 60 years, it was thought that aluminum causes Alzheimer's. The Alzheimer's International Association reports that studies have not confirmed the assumption that aluminum foil plays a role in the cause of Alzheimer's disease, and therefore there is no point in renouncing antiperspirants.
Also once, people believed that antiperspirants cause kidney disease. This myth is refuted by scientists from the National Renal Foundation. They explain that it is impossible to absorb enough aluminum through the skin to damage the kidneys.
In addition, aluminum and parabens in the antiperspirants were guilty of the onset of breast cancer. This myth was denied by the specialists of the National Cancer Institute of the United States and the National Cancer Society.
7. In the day to do 10 thousand steps
10 thousand steps is a totally arbitrary figure, which was invented in Japan for the promotion of the pedometer in the mid 60s. For people with chronic diseases, elderly people, diabetics and those who are accustomed to a sedentary lifestyle, the strong increase in activity can have adverse consequences. Some research suggests that maintaining enough health to make at least 5-8 thousand steps a day. Scientists who tried to calculate the exact number of necessary steps, say that it is desirable to aim at the figure of 7.5 thousand steps.
