Got milk? Reasons Not to Grab for the Glass | Vegetarian Lifestyle

Many Americans, including some vegetarians, still consume large amounts of dairy products, but here are several strong reasons to eliminate dairy products from your diet.

Milk has long been praised as a ‘weapon’ in the war against osteoporosis, but recent clinical research shows that it actually is associated with a higher fracture risk, and there’s been no protective effect of dairy calcium on bone. Increasing your intake of green leafy vegetables and beans, along with exercising have been shown to help strengthen bones and increase their density.

Dairy products are also a significant source of fat and cholesterol in the diet, which can increase your risk for cardiovascular disease. A low-fat vegetarian diet that eliminates dairy products, as well as adequate amounts of exercise, proper stress management and quitting smoking not only will help prevent heart disease, but could also reverse it.

Ovarian, breast, and prostate cancers have been linked to dairy product consumption. According to a recent study by Daniel Cramer, a Harvard doctor, when excessive amounts of dairy products are consumed and the body’s enzymes are unable to keep pace with breaking down the lactose; it can build up in the blood and affect a woman’s ovaries. Another recent study showed that men who had the highest levels of IGF-I, (insulin-like growth factor) which is found in cow’s milk, they were at four times the risk of prostate cancer compared to those men who had the lowest levels of IGF-I.

In addition, milk may not provide a consistent and reliable source of Vitamin D in the diet. Milk samplings have been found to have inconsistent levels of Vitamin D, and some have been found to have as much as 500 times the indicated safe level. Excess Vitamin d in the blood can be toxic and can result in calcium deposits in the body’s soft tissues.

Milk proteins, milk sugar, fat, and saturated fat in dairy products may pose health risks for children and lead to the development of chronic diseases such as obesity, diabetes, and formation of plaques in the circulatory system that can lead to heart disease.

By choosing to consume a nutrient-dense, healthful diet of grains, fruits, vegetables, legumes, and fortified foods including cereals and juices, you can help meet your body’s calcium, potassium, riboflavin, and vitamin D requirements easily and simply, without the added health risks from dairy product consumption.

Vegetarian Diet Plan| Proper Planning Prevents Problems

Special care must be taken when planning a vegetarian diet to ensure proper amounts of nutrients are included daily. Nutrients such as protein, iron, calcium, zinc and vitamins B-12 and D can all be easily incorporated into your vegetarian lifestyle with the proper planning. Here are some guidelines to consider when you are planning your weekly shopping trip and organizing your weekly menu.

Plant proteins alone can provide enough of the essential and non-essential amino acids, as long as sources of dietary protein are varied and caloric intake is high enough to meet energy needs. Whole grains, legumes, vegetables, seeds and nuts all contain both essential and non-essential amino acids. Soy proteins, such as soy milk and tofu, have been shown to be equal to proteins of animal origin.

Vegetarians may have a greater risk of iron deficiency than non-vegetarians. Dried fruits and beans, spinach, and brewer's yeast are all good plant sources of iron.

Vitamin B-12 can be found in some fortified breakfast cereals and soy beverages, some brands of brewer’s yeast as well as vitamin supplements. Read the labels of other foods carefully; you might be surprised what food is B-12 fortified.

As a vegetarian, it’s essential that you have a reliable source of vitamin D, in your diet. Exposure to ultraviolet (UV) light stimulates your body produce its own vitamin D. Daytime outdoor exercise and working in your garden are both great alternatives for obtaining this important nutrient. Those who don’t have the opportunity to get out and soak up the sun might want to consider adding a supplement to their diet.

Recent studies suggest that vegetarians absorb and retain more calcium from foods than their non-vegetarian counterparts. Vegetable greens such as spinach, kale and broccoli, and some legumes and soybean products, are good sources of calcium from plants.

Zinc is imperative for growth and development. Good plant sources include grains, nuts and legumes. However, zinc daily zinc requirements are actually quite low. Take care to select a supplement that contains no more than 15-18 mg zinc.

Vegetarians may have a greater risk of iron deficiency than non-vegetarians. Dried beans, spinach, enriched products, brewer's yeast and dried fruits are all good plant sources of iron. When eaten alongside a fruit or vegetable containing high amounts of vitamin C, your body more willingly absorbs the needed iron, so be sure to team these two vital nutrients up as much as possible when meal planning.
