Objective: To identify foods that are beneficial in the fight against cancer and other diseases. To identify foods which are unhealthy and may cause cancer and other diseases.
What is cancer? Cancer is abnormal cell growth and destruction. It will affect 2 out of every 5 people at some point in their lives. Currently, there is no cure. Nutritional research scientists have given us hope however. They say that, “90% of winning the battle against cancer and other diseases is nutritional self defense.”
What are the causes of cancer and other diseases? Cancer research centers have identified 80- 90% of all cancers as being related to the following toxins: Bad Nutrition—excessive consumption of high animal fat, sugar, and processed foods along with a diet that is low in fiber Lifestyle—Smoking, excessive alcohol consumption, lack of exercise Environment—chemicals and other air pollution Drug Abuse
Nutrients Causes of nutritional deficiencies: Nutrients are being taken out of the food we eat by over processing, over-cooking, chemical preservatives, and bad soil. When our bodies go without the nutrients that we need then our systems begin to break down and get diseases. The 6 classes of nutrients are carbohydrates, proteins, fats, minerals, vitamins, and water From these nutrients the most important food substances are antioxidants, fiber, and omega 3 fatty acids
Important terms related to nutrition… 1. Antioxidants: cleans the cells 2. Fiber: cleans the digestive system 3. Omega 3: cleans and regulates the circulatory system
Oxidants Oxygen-free radicals which are unstable particles believed to cause cell damage and age the body. Antioxidants Antioxidants are foods that clean the cells of our body. They come from fresh fruits and vegetables and are packed with a variety of ferocious antioxidants that resist toxins that seek to destroy our cells.
Antioxidant-rich foods A team of USDA nutritionists published a study in the Journal of Agricultural and Food Chemistry that showed the results of how they took different food samples and measured their antioxidant capacities. The results weren’t surprising: Fruits, vegetables, and beans claimed nearly all the spots in the Top 20.
Top 20 Antioxidants 20. Gala apples 19. Plums 18. Black beans (dried) 17. Russet potatoes (cooked) 16. Black plums 15. Sweet cherries 14. Pecans 13. Granny Smith apples 12. Red delicious apples 11. Strawberries 10. Raspberries 9. Prunes 8. Blackberries 7. Artichokes (cooked) 6. Cranberries 5. Blueberries (cultivated) 4. Pinto beans 3. Red kidney beans 2. Blueberries (wild) 1.Small red beans
So what food groups are great antioxidants? Fruits, vegetables, and beans
Antioxidants: “Fresh” = Better Most antioxidant foods lose some of their antioxidant capacities in processing. (The most notable exception is the tomato; the antioxidant level is actually enhanced by cooking) “Fresh” is the best choice over frozen, cooked, or otherwise processed.
Good Fats vs. Bad Fats Omega-6 fatty acids (bad fats)—These are mostly saturated animal fats that promote blood stickiness and constrict blood vessels. The worst sources of omega-6 fatty acids are: Bacon, lamb, cheese, pork, Butter, beef, margarine, and milk
Good Fats vs. Bad Fats Omega-3 fatty acids (Good fats)— These supply the raw materials that cells need to control blood clotting, joint inflammation, and also frustrates cancer. Omega-3 fats also thin the blood. The best sources are fish from the coldest waters: Salmon, herring, sardines mackerel, anchovies, lake trout Other sources include walnuts and Olive oil
Fiber Fiber —long stringy strands of cells that give strength and support to plant tissue Importance of fiber: Cleans the digestive tract Reduces calories Lowers cholesterol Prevents chronic constipation and diarrhea Helps prevent cancer Helps prevent kidney stones Helps regulate body weight
Good sources of fiber Whole grains, carrots, green beans, tomatoes Turnips, butter beans, oranges, okra, Oat bran cereal, lima beans, corn, onions, Cabbage, baked beans, white beans, Apricots, oatmeal, brussel sprouts, beets Broccoli, black beans, kidney beans, mangos
Diseases and ailments attributed to the lack of fiber Colon cancer Prostate cancer Breast cancer High blood pressure High cholesterol PMS Ovarian cancer
Digestive disorders attributed to lack of fiber Hemorrhoids Constipation Stomach ache
5 Health problems related to food and nutrition 1. Obesity: Being overweight is one of the biggest health problems that we have today. There are many contributing factors to this: Restaurants serve bigger portions More buffets available More fat is put on the food to make it taste better Lack of exercise Genetic problems Problems with the thyroid gland Lack of time to cook nutritious meals
5 Health problems related to food 2. Diabetes: Type 1 diabetes is when the body (pancreas) stops making it’s own insulin which is a hormone that regulates your blood sugar levels. There is evidence to suggest that the reason this happens is that hormones are being put into animals that we consume to cause them to grow at a faster rate so that they can processed for market sooner. When we consume food that has hormones in it then it shuts down our own hormone producing cells such as the beta cells of the pancreas that make insulin.
5 Health problems related to food 3. Food Allergies: For reasons unknown people have certain food allergies. Many people eat food that they don’t even know that they are allergic to.
5 Health problems related to food 4. Headaches: A majority of headaches are related to a constipated digestive system. As a result of food that is in the digestive system too long toxins leak out into the blood stream triggering a headache. Food allergies also contribute. Migraine: a type of painful headache
5 Health problems related to food 5. Heart Attack/Stroke resulting from High Cholesterol: High cholesterol causes hardening and clogging of the arteries and mostly comes form eating too much saturated animal fat. This can lead to a heart attack or a stroke.
