Nuts help against heart disease and colon cancer
A number of studies have been able to demonstrate how nuts affect the human body. It was found that nuts, for example, significantly reduced the risk of developing colon cancer. Other studies indicate that regular nut consumption also protects against heart disease. In the following we show which studies have reached which findings. However, nuts are not a panacea. Rather, they are one of many factors in leading a healthy life.
A team of researchers from the Dana-Farber Cancer Institute in Bosten, USA, recently showed in a study that colon cancer patients who eat nuts regularly have a better chance (42 percent) of the disease not returning seven years after their surgery, as well as a lower risk of death (57 percent) compared to patients who did not eat nuts. Another study by the "Department of Nutrition" from the "Harvard School of Public Health" in Boston, USA, showed that eating nuts several times a week with a 30 to 50 percent lower risk of heart attacks, sudden cardiac death or cardiovascular diseases related.
Nuts and colon cancer
Surviving colorectal cancer thanks to nuts: “Eating nuts is one of the factors that can potentially change the risk of developing colon cancer,” says study author Dr. Temidayo Fadelu in a press release on the study results. However, nuts are not a substitute for standard therapies. The benefits were also only found on tree nuts such as walnuts and almonds. With peanuts (actually a legume) or peanut butter, the positive aspects did not appear.
Generally lower risk of death from cancer
The work builds on earlier studies on the effects of lifestyle on the development of cancer. The large observational study from the New England Journal of Medicine in 2013 showed that people who ate nuts every day were 11 percent less likely to die from cancer than people who ate no nuts.
Nuts are healthy, but not a panacea
Fadelu clarifies that nut consumption is just one factor among a range of healthy behaviors that reduce the likelihood of colon cancer. Increased physical activity, a healthy weight and the low intake of sugar and sugared drinks also help to reduce the likelihood of colon cancer.
Nuts and heart disease
Eating nuts regularly protects against deadly cardiovascular diseases. Further studies have shown that regular nut consumption can also help prevent heart disease. "A diet that contains 30 grams of nuts a day can reduce the risk of heart disease," writes the Department of Nutrition of the Harvard School of Public Health in a press release.
Nuts have a positive effect on cholesterol levels
The unsaturated fats that contain nuts lower the bad LDL cholesterol and raise the good HDL cholesterol. Walnuts in particular contain a group of unsaturated fatty acids (omega-3) that, according to the scientists, seem to prevent the development of cardiac arrhythmias such as cardiac fibrillation. Omega-3 fatty acids can also help prevent blood clots and are also found in oily fish such as salmon.
Beware of weight gain
However, the experts warn against simply adding the nuts to the menu. 30 grams of nuts have about 185 calories. Anyone who consumes them a day could gain up to five kilos in a year. According to the scientists, it is best to reduce other less healthy snacks such as chips and eat the nuts for them or use them instead of meat in main dishes or salads. (vb)
