Cardiovascular Benefits Besides being a very good source of protein, lean, beef is a very good source of Vitamin B12, & a great source of Vitamin B6. These two essential B’s are needed by the body to neutralize the potentially dangerous chemical homocysteine, and high levels may be associated with an increased risk of heart attack & stroke.
Cancer Protection Diets high in Vit B12-rich foods, & low in fat, are also associated with a reduced risk of colon cancer. Selenium, is another nutrient in lean beef that helps reduce the risk of colon cancer, & is necessary for the proper function of glutathione peroxidase, an important antioxidant in the body used by the liver to detoxify harmful molecules, which may damage cellular DNA & promote cancer. Asparagus is a leading source of glutathione as well as broccoli, avocado & spinach. Raw eggs, garlic & fresh meats contain higher levels of amino acids & help to maintain optimal glutathione levels. Foods rich in selenium (naturally grown calf’s liver, brazil nuts) are also associated with a reduced risk for colon cancer. A 120gm serving of lean beef supplies 50% of the daily selenium. Lean beef is also a great source of Zinc, which is needed for good immune systems function & may help prevent atherosclerosis.
New research suggests that another reason for older men to make zinc-rich foods, such as beef, a regular part of their healthy way of eating is bone mineral density. Osteoporosis is also a potential problem for older men, not just women. A 120 gm serve of lean beef contains 42% of the daily value for zinc. So don't think eating healthy means reducing meat in your diet, as lean, low-fat naturally grown beef is actually a great healthy basis for a naturally balanced whole foods diet.
