Of salt and coffee for prostate cancer .. The largest 8 "health coups"

Eighty years ago, doctors advised that cigarettes be treated as a cure. Now, it is completely different.

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

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

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

One of those studies said that those who drank between 3 to 4 cups of coffee a day have lower mortality rates than those who do not drink coffee altogether, 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.

2. 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, the mice dealt with the equivalent amount of proportionality that Americans take daily.

In 2016, a study was published to dispel this concern, noting that the risk of salt is limited 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.

3. Fat: Butter, coconut oil are two types of fat that have been reduced to fear, because heart specialists have realized that these fats are not fatal, but this does not mean that saturated fats are still a dilemma, as they can contribute to heart attacks.

4. Meat: Years ago, the World Health Organization (WHO) announced that sausages and processed meats 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.

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

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

6. Eating late at night: Nutritionists used to say that calories are calories regardless of their consumption time, but recent studies have concluded that overweight adults who ate a large breakfast, a light meal and a simple dinner made Better results in blood sugar, insulin and cardiovascular risk factors than those who eat more food at night.

7. 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 clinic, this test resulted in 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 it is advisable to consult with 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.

8. Prostate cancer tests: During the 1990s, health experts recommended that an annual blood test be performed on the detection of prostate cancer. Recent studies have found that the PSA may not produce desired results, so this test may be withdrawn. Misleading and damaging men.
