Some reasons for diet changes (cutting back and switching to organic dairy).

My little family and I are slowly transitioning to a healthier diet while baby is in the womb to cut back on anti-biotics and growth harmones. We are not going completely vegan, but getting protiens from wild meats, nuts, soybeans. We are very fortunate to live in this part of the world to have access to local vegetables and wild meat. Most dairy is part of a billion dollar industry, so we are willing to spend a few extra dollars for organic dairy, not from the steriod cows.

1. Reduced saturated fats. Dairy products and meats contain a large amount of saturated fats. By reducing the amount of saturated fats from your diet, you’ll improve your health tremendously, especially when it comes to cardiovascular health.
2. Protein. That protein is good for your body is no surprise. It may be a surprise to learn that most Americans eat too much protein and in forms such as red meat that are not healthy ways of getting protein. Beans, nuts, peas, lentils, and soy products are all great ways to get the right amount of protein in a vegan diet.
3. Cardiovascular disease. Eating nuts and whole grains, while eliminating dairy products and meat, will improve your cardiovascular health. A British study indicates that a vegan diet reduces the risk for heart disease and Type 2 diabetes. Vegan diets go far in preventing heart attack and stroke.
4. Body Mass Index. Several population studies show that a diet without meat leads to lower BMIs–usually an indicator of a healthy weight and lack of fat on the body. (The biggest reason for me to try this diet change, I work out, but still carry alot of extra weight).
5. Animal proteins. The average American eats twice as much protein as necessary for a healthy diet and much of that is from red meat. Getting protein from beans and grains is much healthier and reduces the risk for osteoporosis (see above).
6. Cow’s milk dairy. The human body is not designed to digest cow milk and cow milk dairy products, yet the idea of milk being healthy is pushed through advertising. As many as 75% of people in the world may be lactose intolerant and many people suffer from undiagnosed milk allergies or sensitivities. By eliminating cow’s milk from your diet, you are improving your overall health.
7. Animals. Many people begin a vegan diet out of concern for animals. Whether opposed to the conditions of animals intended for food or eating animals in general, going vegan will help your conscience rest easily.
8. Hormone consumption. Eating animals that have been given hormones to speed growth (a common practice in the meat industry) means those hormones go into your body. Not only can this disrupt the natural balance of your hormones, but some of the hormones given to animals have shown to cause tumor growth in humans.
9. Antibiotics. Antibiotics are frequently given to feed animals, which can lead to bacterial resistance. Many of the antibiotics used to treat human infections are also used in feed animals.
