Anti-Cancer Diet - Part One
Would you believe me if I said there is an anti-cancer diet. This diet helps prevent, heal, and keep cancer in remission. According to Dr. Bill Sears, there is a diet that can do all of these things. Below I will go over the first part of the elements to the diet and how it works.
BASIC PRINCIPLES:
- Maintain a diet low in total fat as well as very low in saturated fats.
- There are 2 ways that fat contributes to cancer. Tumor cells require low density lipoproteins to grow. So eating a diet low in LDL may keep cancer cells from growing.
- Consuming fat stimulates the production of bile. If a large amount of bile is allowed to sit in the intestines it will be converted into apcholic acid, a carcinogen or cancer causing agent.
TIPS:
- Eat less total fat: limit your fat intake to no more than 20% of your total food calories. So if you usually eat 2,500 calories/day, fat should not provide any more than 500 calories. This would translate to about 55g of fat per day.
- Eat the right fat: If you are eating the wrong kind of fat you may be doing more damage than eating too much fat in general. Researchers noticed that the incidence of most cancers is far less in some cultures that consume a high-fat diet like Eskimos and Mediterraneans. However, the key is in the fat they do consume. Eskimos consume a diet rich in seafood that is packed with omega 3 fatty acids and the Mediterranean people consume a high-fat diet that is plant-based but high in monounsaturated oils. This means that some types of fat do not lead to cancer but may actually have anticancer properties:
- Unsaturated fats derived from plants like legumes
- Monounsaturated fats found in vegetable oil, olive oil, and canola oil. * *
- Omega 3 Fatty Acids found in seafood like salmon and tuna
- Omega 3 and 6 Fatty Acids found in oils like flaxseed, pumpkin seed, canola, soybean, walnut, safflower, sunflower, sesame, and virgin olive oils.*
*Greek women who consume a diet high in olive oil often have a low incidence of breast cancer.
* A study conducted in 1998 illustrated that men who consume less fat from animals and more from vegetables were at less risk for prostate cancer.
* However when vegetable oils are heated at high temperatures it can alter fatty acids rendering them carcinogenic. Extra virgin olive oil as well as peanut oil work best for cooking, but remember to stir often to prevent burning.
STUDIES AND RESEARCH:
- In animal based experiments it was shown that animals that received a fish-oil supplement developed less colorectal tumors.
- Omega 3 Fatty acids are the most heart-healthy fats and may have anticancer properties.
- Eskimo women who consume a large amount of omega 3 fatty acids have a lower incidence of breast cancer.
Avoid bad fats:
- It is important to strictly avoid fats and oils high in saturated fats like palm, palm kernel, coconut, and cottonseed.
- You also want to avoid all hydrogenated fats. These fats are also referred to as Trans fats, they have been chemically altered changing them from unsaturated to saturated fats. These fats have a hydrogen molecule added to them, possibly making them carcinogenic. The hydrogen molecule interrupts the normal cell metabolism in the body, setting the stage for cancerous changes in cells. Be sure to read the labels, if a food contains anything hydrogenated, partially hydrogenated, or has trans fats leave it on the shelf.
