“What do I do to keep the cancer from coming back?” “What do I eat?” “What do I not eat?” “How do I live a cancer free life/lifestyle?” These questions are ones that I hear from my patients every day. Hippocrates said it best, “let your food be your medicine, and your medicine, your food.” Let’s start with establishing some basic food guidelines for cancer and chronic disease prevention.

Reduce your risk factors through diet.

Don’t get bogged down on all the different kinds of diets that you find online. Variety is the spice of life. There is no “one diet” for everyone, however, there is a diet that everyone can certainly avoid; the “SAD” or “Standard American/Western Diet”. It is estimated that dietary factors are related to 30% of all cancer development, and the SAD diet captures them all. When eaten over time, foods high in poor quality protein, refined sugars/carbohydrates, and bad fats (breads, processed foods, pastries, fried foods, fast foods) can lead to the development of cancer by influencing your genetics, environmental exposures, stress, depleted immune system, and weight. Remember, there is one facet that you ultimately control; your food!

Avoid these Top 5 inflammatory foods:
1) Alcohol- Alcohol is a poison to your body and causes blood sugar imbalance. Alcohol has a direct and linear correlation with increase risk of multiple types of cancer. A 2011 European study of 350,000 men and women estimated about 10% and 3% of all cancer in European men and women respectively, would be the result of alcohol consumption. So the more alcohol you drink on a daily basis, the higher your chances are of getting cancer.
2) Grains, legumes/beans, and refined carbohydrates- All grains and legumes have molecules called lectins, an inflammatory glycoprotein, that in great enough quantity, can strip away your gut lining. These food products also increase your blood sugar and can spike your insulin levels, leading to increased weight gain and the risk of diabetes, heart disease, and cancer. It’s not enough to avoid all the “white foods” anymore.
3) Sugars- Sugar is used as fuel in all of your cells, so you do need some sugar in your body. However, too much sugar is inflammatory to your body. Over time, it can increase your chances of diabetes and obesity- two strong risk factors for cancer development.
4) Processed “food”- Processed foods are high in sodium, chemical preservatives, and food coloring, and are low in nutrient value. Skip the convenience excuse and invest time in your health by eating whole foods as much as possible.
5) Non-organic meat and dairy products- Non organic meats and dairy products are often contaminated with antibiotics, pesticides, growth hormones, and unhealthy fats. Choose cleaner, leaner options such as bison, grass-fed beef and lamb, and wild caught fish.

Heal your gut!
The key to health starts in your gut. The unfortunate side effect of conventional cancer treatment is the destruction of your digestive system. The first step in any type of recovery is healing the impaired digestive system and restoring proper function. There are many steps in this process, however, one of the most important steps is removing foods that cause more inflammation in an already inflamed gut. The more you reduce inflammation, the more your body can heal and recover and the more you reduce your risk of cancer.
