PROTECTING OUR HEALTH WITH PLANT FOODS(cont.) Excess cholesterol forms a fatty build-up that lines blood vessels and restricts blood flow carrying needed oxygen and nutrients in our bodies. This condition is known as atherosclerosis. Saturated fats, contained mostly in animal foods, raise blood cholesterol level more than any other factor. However, antioxidants (vitamins C and E, and other plant components) and folic acid, present only in plant foods, work to protect arteries from plaque formation. When fatty build-up restricts blood flow, blood pressure rises, and this leads to a condition known as hypertension. Salt consumption increases water retention and blood volume, promoting hypertension. An artery leading to the heart can become blocked, killing a portion of the heart muscle and causing a heart attack. Obstruction of an artery leading to the brain may kill a portion of the brain, causing a stroke. CANCERS Cancer occurs when certain cells begin to grow out of control. Eventually, they start to destroy important parts of the body. Cancers of the lung, breast, prostate, colon and other digestive organs are closely connected with a diet high in animal foods. Several reasons have been identified. For example, consumption of animal fats raises blood testosterone and estrogen levels, leading to prostate and breast cancers. Fortunately, plant foods contain fiber which prevents colon cancer by helping to pass food through the digestive tract before cancerous growth can get very far. They also contain special compounds, phytochemicals and antioxidants, that make it harder for cancer cells to start forming. DIABETES The cells of our body feed on glucose which is escorted by a hormone called insulin. Animal fat in the bloodstream prevents insulin from playing its vital role. This causes adult-onset or type II diabetes. DISCUSSION QUESTIONS 1) Name some of your favorite fruits and vegetables and tell why you like them. 2) What are some of the health benefits of plant foods? 3) How many servings of fruits and vegetables should you eat? 4) What do you think are some of the advantages of being healthy? 5) What foods can you eat to improve your own health? 6) Which of these foods are you going to eat in the next week?
