Nutrition, overweight and cancer


Since many years it is known the link between proper nutrition and the onset of cancer. At present it is estimated that if everybody adopted a lifestyle correct you could avoid the appearance of about a case of cancer in three. Choose a healthy eating at the table, abandoning harmful lifestyles such as smoking habits or alcohol abuse, staying active and healthy body weight, are all elements that play a crucial role not only in the onset of the disease but even in the course of the same.

In particular the severe overweight or obesity is a major risk factor not only for the development of cancer but also for many other chronic diseases. Obesity is often defined simply as a condition of abnormal or excessive fat accumulation in the fatty tissues of the body leading to health hazards. The underlying cause is a positive energy that determines a weight increase; in other words when the calories consumed exceed the calories expended. Often, however, a situation of overweight or obesity is associated to a state of permanent inflammation, and it is the persistence of this situation which can create the basis for the development of the cancer disease. The positive side is that many cancers are largely preventable through sensible changes in their lifestyle.

Tentatively, to help the person determine your ideal weight, it uses a simple measurement of the relationship between weight and height called the Body Mass Index (BMI). Despite its shortcomings (especially in the evaluation of people with particularly muscular physique), the BMI is a useful tool to determine the prevalence of underweight, overweight and obesity in adults. It is defined as the weight in kilograms divided by height in meters squared (kg / m2). For example, an adult who weighs 70 kg and height is 1.75 m will have a BMI of 22.9.

Fall under the classification of overweight and obese individuals with a BMI value respectively greater than or equal to 25 and 30.
