Set random nutritional requirements of a cancer patient is an impossible task, since each patient by age, sex, type of cancer and medical history is a particular case. But we can talk about the advice in nutrition, as general guidelines that should always be confirmed with the oncologist.

Cancer treatment and the disease itself produce states of malnutrition in the patient, which directly affects their quality of life.

Consider the general nutrition advice for cancer:

• Fats: As cancer patients often experience fat loss and muscle mass, it is recommended that the daily calorie intake is at least 25% of everything consumed.

• Protein: protein consumption stands at 15% of daily intake, for example, should consume 1.5 to 2 grams of protein per weight of the person. A 70 kgr should consume between 105 and 140 g of protein per day.

• Fiber: is so important for those suffering from colon or rectal cancer because it has a protective effect.

• Carbohydrates: the right amount is between 50 to 60% of daily intake for an average adult.

Each of these values may be altered in their rate, because each patient has a table space and its particular body reacts to disease. Nutrition should be tailored to each patient, with appropriate medical monitoring.
