Removing some common misconceptions

There are not so many things to worry about today as we thought. Is removing them from the 'black list' a great thing? Researchers have recently been able to overwrite common myths that have been repeated so many times that people think they are really accurate.

Here are 5 myths that you can remove from your head from now on:

Myth one: Start before playing sports to prevent injury

Fact: There is no evidence to support a long-standing assumption that stretching your arms for 20 to 30 seconds will help your muscles work properly. On the contrary, we now know that the actual restart is weak, thanks to a recent report by the University of Nevada. The report also recommends running for 5 to 10 minutes before playing sports.

Second thought: Eat eggs that raise cholesterol

Fact: In the 1960s and 1970s, scientists thought that blood cholesterol increased cardiovascular disease and eggs were accused of this. Many new studies have now found that saturated fat in the diet brings a higher risk of cardiovascular disease, according to the American Heart Association. An egg has only 1.6 grams of saturated fatty acids, compared with about 3 grams in a 2% milk cup. At 213 milligrams of cholesterol in the substance, eggs do not cause concern because the AHA recommends not eating more than 300 milligrams of cholesterol a day. Just pay attention to the amount of cholesterol in other foods you eat every day.

Myth 3: Cancer cannot be prevented

Fact: About 50% or more of cancer deaths in the United States have causes and social or environmental conditions along with unhealthy choices, according to the Centers for Disease Control and Prevention. In general, you can help your body prevent cancer if you don't smoke or avoid smoking from others, avoid drinking too much alcohol, avoid gaining weight, eating 5 or more servings of fruits and vegetables Every day, have a low-fat diet and exercise.

Myth 4: Shaving your hair will help your hair grow faster, thicker and darker

Fact: A clinical trial was conducted in 1928 to compare the growth of hair in the hair that has been shaved to the unshaven hair. New hair replaces old hair that has been shaved without darker or thicker, and doesn't grow any faster , according to researchers at Indiana University Medical School. They were also those who had exposed seven long-standing medical beliefs given in the 2007 report. When hair grows after shaving, it has an edge at the top. Over time, this edge itself is worn out, so the hair seems to be thicker than it actually is. The hair only looks darker because it hasn't been changed by the sun.

Myth 5: You should drink at least 8 glasses of water a day

Fact: A 1945 paper by the National Research Council confirmed that the adult's allowable amount of water is 2.5 liters a day. The last sentence that the article emphasized is that much of that water is already in the food we eat, but most people ignore it. Current studies suggest that we already have enough water from everyday eating activities like drinking fruit juice, milk and even caffeinated drinks, according to researchers at Indiana University.
