    The Problems with Soy

    Perceived as the girl’s protein, the vegetarian soy protein can be equally effective as animal protein sources. The scientific findings, however, believe that soy is not the ideal protein source for women.

    As part of the family of legumes, unfermented soy is known to have high levels of phytic acid. Phytic acid can be beneficial to the body particularly for male meat eaters due to its ability to bind with minerals. This substance is however blocking the uptake of essential minerals like magnesium, copper, iron, calcium, iodine, and zinc. Because of this, it slows down the growth process and can also affect the thyroid hormones. This can be really disadvantageous for women and children. This can also affect individuals who are following a vegetarian diet because of the lesser amounts of minerals in the foods they eat.

    Soy meal replacement, especially when consumed in large volume every day, has other negative effects to health. It can contribute to thyroid disorder, particularly among women. It likewise promotes kidney stones and can weaken the immune system. As a big part of one’s diet, soy-based meal replacement can cause food allergies and digestive intolerance in some people as well.

    Another disturbing effect of unfermented soy can be attributed to its high levels of phytoestrogens. Based on studies, these phytoestrogens can affect the hormonal balance in the body. Its negative effects include low testosterone, delayed menstrual cycle in women, and slower metabolic rate.

    Meal Replacement Shakes Without Soy

    There are many varieties of meal meal replacement shakes in the market today such as the rice bran meal replacement shakes. The only problem is that most of these shakes contain soy protein. Because of its possible negative effect to health, particularly to women, children, and vegetarians, it is recommended that one choose the meal replacement shakes without soy.

    There are different types of non-soy protein shakes including whey, casein, egg, and milk. Depending on how readily digestible the protein source and the manufacturing process it went through, the choice of the protein shake would largely affect your nutrition.

    Eggs and milk are two common ingredients in homemade protein shakes. In egg protein shakes, most people use egg whites only. Nevertheless, there are a few who opt to include the whole eggs with their protein shakes. Milk protein shakes are also good sources of protein.

    But for commercially available protein powders, the two most common forms of protein sources are whey protein and casein protein.

    Whey Protein

    One of the better non-soy options that are readily available is the whey protein meal replacement shake. It is a special type of fast-absorbing protein found in milk. This protein is a great supplement for post-workout diets. Because of its highly digestible form, the main disadvantage, however, is that it can let you get hungry quite easily. This may not be appropriate for people who want to effectively lose weight. After all, meal replacement shakes are usually part of a weight loss diet plan.

    Casein Protein

    On the other hand, casein protein is the main protein found in milk that separates from whey protein. This type of protein is slow absorbing and allows you to be fuller for longer periods to stick with the diet plan.

    The better alternative for meal replacement shakes without soy is protein powder with whey and casein protein mix. For meal replacements in weight loss plans, protein shakes with only casein protein is also highly recommended.
