1. Conjugated Linoleic Acid (CLA)
Found in the meat and milk of grass-fed animals, like cows, CLA is a potent nutrient. CLA is known as a potent antioxidant and anti-carcinogen. CLA has shown promise in the treatment of various cancers. Has shown promise in the fight against breast cancer. Further, CLA even could be valuable in the treatment of brain cancer due to its ability to prevent the development of new malignant tumors. Also from the University of Wisconsin CLA is found in popular weight loss products because it promotes fat burning. IT IS ONLY FOUND IN GRASS FED MEAT
Red meat is a rich source of iron; better yet, it’s a rich source of the most easily absorbed iron: heme iron. Contrasted with red meat plant sources of iron, like lentils, offer non-heme iron which is poorly absorbed. Iron is critical to health because, when properly absorbed, it assists the blood’s hemoglobin in carrying oxygen to the body’s cells. Low iron may lead to fatigue, headaches and dizziness. Important for women particularly during and after menstruation when the loss of blood brings down iron levels.
3. Stearic Acid
Stearic acid is a saturated fat found in beef and other meats. Despite the current and prevalent thought that saturated fats cause an elevation in cholesterol, research indicates that stearic acid actually lowers LDL cholesterol
Red meat is an easy source of complete protein. Protein is essential to the human diet not only because it provides energy, but also because it is critical to the growth and repair of cells. Every cell in the human body contains protein including the antibody cells of the immune system which protect the body against pathogens.
The mineral zinc plays an important role in human health. It is essential for immune system function and can combat the effects of premature aging due to its anti-inflammatory properties. Zinc also plays an important role in skin health, particularly in healing from afflictions like acne and eczema. Zinc deficiency is linked to skin disorders like dermatitis. Maternal intake of zinc is also critical to infant and child health.
6. B Vitamins
Red meat is a potent source of B vitamins, particularly vitamin B12. These nutrients are concentrated in the organ meats–particularly, the liver. B vitamins are essential to cognitive and emotional function. B vitamin deficiency is linked to depression. Inadequate maternal intake of B vitamins during the months prior to pregnancy and during pregnancy itself are thought to contribute to poor infant growth, cognitive and social development in children.
7. Vitamin A
Vitamin A is a fat-soluble vitamin noted for its positive effects on health. Vitamin A promotes fertility, good vision and immunity. Vitamin A is essential to properly functioning immune and endocrine systems while beta-carotene is a potent anti-carcinogen due it is powerful antioxidant activity. The fat from grass-fed cows, lambs and bison is rich in these nutrients–greatly more so than the fat of conventionally fed animals from concentration animal feed operations (CAFOs and feedlots).
Think fish – EPA or omega 3s. Similarly, the fat from naturally fed cows and other ruminants contains significant amounts of EPA. This omega-3 fatty acid is essential for cognitive function and emotional health and is only naturally available from animal food sources. EPA is known for its many health benefits including protection from cardiovascular disease, cognitive function and emotional well-being. Combinations of EPA and DHA (both only found in grass fed animals) fatty acids have shown remarkable benefits in treating ADHD/ADD, schizophrenia, bipolar disorder, autism and even dyslexia. Grass-finished meat represents an excellent source for EPA due to its favorable omega 3 to omega 6 fatty acid ratio. Grass-finished meat offers an omega 3 to omega 6 ratio of approximately 1 part omega-3 fatty acids to 2 parts omega-6 fatty acids; by contrast, conventionally fed cows produce meat with a much less favorable ratio and are lacking in the vital nutrient EPA.
9. Mono-unsaturated Fat
Beef fat is comprised of approximately 35% monounsaturated fat. The consumption of monounsaturated fats are linked to a reduction in LDL cholesterol and an increase in HDL cholesterol (good cholesterol)–particularly among insulin-resistant individuals.
Traditionally, red meat has comprised an important element of the human diet. Consider the venison that nourished Europeans, the bison that nourished the Native Americans or the lamb and mutton that provided sustenance for the nomads of the Middle East: all of these foods provide value to the diet including wholesome fats, vital protein, minerals and vitamins. Red meat has been part of the human diet for millennia – yet the people who consumed it didn’t suffer from cancers or heart disease or other diseases of industrialization; rather, they benefited from its many positive and essential nutrients. If it nourished your ancestors, it can nourish you too. Take care to purchase only grass-finished meats which offer the very best nutritional profile.
