Cancer and Excess weight: thin edge!

After gathering all the scientific evidence available, the global research against cancer Fund (GRCF) released a list of foods to avoid and in cancer. But the data also analyzed in relation to excess weight and fatness with cancer in general and more specifically certain types of cancers.

Too much weight increases the risk of certain cancers

Excess weight is a negative element vis-à-vis the risk of cancer. It is conventionally defined as body size or body mass index (BMI) which is calculated by dividing twice the weight by height. In its report, the Global Fund against Cancer Research indicates that the risk of many cancers increases with body size. Thus, except for breast cancer before menopause, excess weight increases convincingly colorectal cancer, breast cancer after menopause, endometrial cancer and kidney cancer. This increase is suggested for cancer of the gallbladder and the liver. At the same time, it is clear that the practice of physical activity decreases with a very high level of evidence, the risk of weight gain and overweight, but also the risk of colorectal cancer, breast cancer after menopause and the endometrium.

In a more general way, we note that the 8 recommendations of the experts involved in this work, three directly implicate weight. "Being as thin as possible, within the normal weight range" This range is defined by BMI, which must be between 21 and 23 adults. Adults should avoid weight gain and increased waist circumference. In children and adolescents, it is recommended to follow the evolution of the weight curve during growth so that the BMI reaches the lower end of the normal range at the age of 21 years.

"Limit consumption of energy-dense foods and avoid sugary drinks" The energy-dense foods are defined by a higher energy intake or equal to about 225-275 calories / 100 grams. Experts warn against ready meals and fast food because they typically have a high caloric density if eaten frequently and in large quantities. On sugary drinks, recommendation focuses on beverages containing added sugar, but it is also advisable to limit fruit juices. "Being physically active every day," For this, it is recommended to practice for at least 30 minutes each day of moderate physical activity, comparable to a brisk walk. Experts state that this activity can be integrated leisure.  Activities noted that the fight against overweight fits just as fully in the prevention of cardiovascular disease (cholesterol, blood pressure ??) and diabetes. But more generally, physical activity is an essential part of a healthy lifestyle for overall good health, both physical and mental.
