Cancer Nutrition - What Causes Cancer? Diet for oncology
When we hear in the media or from acquaintances that there are anti-cancer products that are excellent ways to prevent cancer and even help to cure it, this causes some skepticism in many. Is it really? Whether the substances contained in certain foods can affect the processes in the body caused by cancer, we will try to study in this article.
The role of nutrition in the body
Gone are the days of food shortages and shortages. Today, the shelves of shops and supermarkets abound in a variety of products, for different tastes and colors. The life of people was made easier by the appearance of all kinds of semi-finished products, instant soups and cereals, which are enough to fill with water and the food is ready. Due to the changed rhythm of life, people eat on the go, snacking on a sandwich with sausage or sausage. It's so tasty and satisfying. But all this has a second side of the coin. Consumption of food containing carcinogens, dyes, flavors, a sedentary lifestyle, uncontrolled intake of certain medications, including antibiotics, suppress the human immune system and, as a result, leads to various kinds of diseases.
It seems to us that such a disease as cancer will never touch us, and even if someone close to us is diagnosed with cancer, we believe that this is a coincidence of circumstances beyond our control. But scientists, who have been studying the role of nutrition in our body for many years, have come to the conclusion that unbalanced and poor-quality nutrition often leads to the formation of all kinds of tumors. If, nevertheless, the disease has not passed, the role, especially at the stage of the patient's recovery, is invaluable.
A person loses a huge amount of vitamins, minerals, protein, trace elements, which can only be replenished with a balanced diet. In this regard, scientists have developed a special diet for patients with cancer. On the advice of the oncologist, the patient must adhere to this diet. With some types of cancer, such as cancer of the stomach, throat, oral cavity, as well as after surgery, eating becomes extremely painful and in some cases impossible. In such situations, a special probe is used to introduce food.

Foods that can inhibit cancer cells
As you know, the treatment of cancer is a rather complicated process. The radiation used, which kills cancer cells, are certainly effective methods of treatment, but at the same time they strongly suppress the already weakened human immunity. How to defeat the disease, and what is the role of products in this difficult struggle, we will try to answer these questions. Experts advise to include in the diet foods that increase immunity and can suppress cancer cells. These foods are readily available and can be included in your daily diet.
Eating dairy products, scientists did not come to an unambiguous conclusion, since along with the content of useful elements such as calcium, milk and dairy products, they contain substances that provoke the development of cancer. Nevertheless, doctors recommend including in the diet low-fat dairy products, such as kefir.
Of particular note are foods that contain antioxidants.... These substances have a number of medicinal properties, in particular, and a rejuvenating effect. This effect is achieved by the ability of antioxidants to remove free radicals from the body. Scientists have found that antioxidants have cancer-preventing properties. The body itself is capable of producing antioxidants, but their amount is negligible. Nature has given us the ability to obtain antioxidants from many vegetables, fruits and berries. These include red berries: currants, sea buckthorn, lingonberries, cranberries, pomegranates, citrus fruits, cherries, strawberries, plums, some varieties of apples, nuts, dried fruits. This list is far from definitive. We will consider some of them in detail.
Broccoli
Broccoli belongs to the cruciferous vegetable family, which contains the substance sulforaphane. Scientists at the University of Michigan (USA) have shown that sulforaphane is able to stimulate the growth of stem cells. Stem cells are not yet fully understood type of body cells. But it is known that these cells are capable of destroying.

Tomatoes
The red color of the tomato is given by the substances lycopene and carotenoids. It is these substances, according to scientists, that can be attributed to substances that help fight cancer cells. Namely, it is an excellent prophylactic agent for cervical cancer. Men who regularly consume tomatoes prevent their risk of developing. This is achieved due to the fact that lycopene suppresses the action of androgens. Androgens are hormones that form prostate tissue hypertrophy.

Walnuts
Walnuts are a real remedy for preventing breast cancer, as well as in women. This effect is achieved thanks to the substance phytosterol contained in walnuts. Also in the composition of the walnut there is a substance irreplaceable for our body - selenium. With a deficiency of selenium in the body, a person's immunity decreases, the bones become fragile. A decrease in immunity, as you know, contributes to an increase in the number of cancer cells.
Daily rate is 100-150 g per day. To replenish selenium in the body, it is enough to consume 4-5 nuts per day.

Cancer patients, after sessions of radiation or chemotherapy, lose a large number of calories, which is why they quickly lose weight. Despite some food prohibitions and prescribed diets during cancer treatment or rehabilitation, doctors allow the inclusion of easily digestible carbohydrates and glucose in the patient's diet, such as baked goods, chocolate, dried fruits (dates, dried apricots, prunes), honey. Sweet things can sometimes be a kind of psychological therapy for a patient who is exhausted by the treatment processes. The patient often lacks appetite.
To improve appetite, the patient's menu can be supplemented with seasonings (cloves, cinnamon, parsley, ginger, etc.), adding them during the cooking process.
For each type of cancer, a special diet is provided, developed by specialists, where you can find recipes for dishes and foods that can be included in the patient's diet, and especially cooking.
Cancer-promoting foods
Along with healthy products, we will indicate products that are not recommended, and in some cases are prohibited for consumption, in order to avoid various diseases, including malignant tumors.
The list of products that contain anti-cancer ingredients and the list of cancer-causing ones is incomplete. In any case, you need to know when to stop in everything and when buying products, carefully study the composition. Fortunately, now it is possible to find out all the names of the substances that make up the products encrypted by manufacturers. It has long been proven that proper nutrition and a healthy lifestyle prevent the occurrence of many diseases, including cancer.
