The largest 8 health coups

Eighty years ago, doctors advised to take cigarettes as a cure, and now, quite differently, they have become a big evil.

Cigarettes are one of the many health issues that science and scientists have changed a lot, as new studies refute their predecessors.

The Reader’s Digest reviewed a number of these issues and how their outlook changed:

Coffee: This drink has been criticized as a cause of high blood pressure, heart attacks and others. In the last decade, the reputation of coffee has improved considerably, as it has become useful according to many studies.

One of those studies said that those who drink between 3 to 4 cups of coffee a day have lower mortality rates than those who do not drink coffee permanently, and this drink reduces the risk of some cancers such as liver.

However, it is not a rosy thing. Pregnant women may be allergic to coffee.

Salt: During the 1970s, researchers tested the effect of rat intake on salt, and the result was alarming for its negative effect on raising blood pressure to alarming levels, because of the commonalities between these creatures (mouse and human).

In the experiment, mice treated the amount of equality and proportionality that Americans take daily.

In 2016, a study was published to dispel this concern, noting that the risk of salt is confined to the bodies of those who over-intake, and who suffer from high blood pressure and already suffer from problems related to the heart and blood vessels.

Fat: Butter, coconut oil are two types of lipid fat that I have been afraid of, because heart specialists have realized that these fats are not lethal, but that does not mean saturated fats are still a dilemma. They can contribute to heart attacks.

Meat: Years ago, the World Health Organization (WHO) said sausages and processed meat increased the risk of cancer, but according to a new study, eating meat in reasonable quantities poses a much lower risk than that associated with smoking.

However, the risk of eating meat can be associated with its consumption level.

Gluten: For people with gastrointestinal disease, gluten (a protein compound found primarily in wheat and barley) can be very harmful, as it can lead to negative interactions in the intestine.

But for most of us, this protein does not seem to be an inherent problem, according to Mayo Clinic.

Late-night eating: Nutritionists used to say calories are calories regardless of their consumption, but recent studies have found that overweight adults who ate a large breakfast, a light meal, and a simple dinner did better In blood sugar tests, insulin and cardiovascular risk factors, compared to those who eat more food at night.

Mammography: In the 1980s, the American Cancer Society recommended that women perform an annual screening test to check for breast cancer. According to the Mayo Clinic, this test has led to a massive detection of the symptoms of this disease and saved many lives.

But recent studies have confirmed that many of these symptoms will not progress to a dangerous stage, and therefore it is advisable to resort to a doctor to discuss when the examination begins according to the medical record of women, and recommends a study to wait until the age of 50 years.

Prostate cancer tests: During the 1990s, health experts recommended that an annual blood test be performed on the detection of prostate cancer, and recent studies have found that the PSA may not produce desired results, so this test may be withdrawn because it may be misleading and Damage to men.
