For years, we have been told whey protein is the way to go, but I want to challenge that opinion.
What is whey? Well, whey protein isolate is a by-product from cheese-making. It’s the clear liquid used after the milk has curdled and is often used to feed pigs. Humans aren’t designed to drink cow’s milk, calves are!
Milk contains so many hormones and is estrogen heavy…men I am sure you don’t want to have to worry about your estrogen levels.
Whey is hard to digest !
“If we have special protein powders created from cow’s milk for human consumption, it would only make sense that it must be because our society sees a very high rate of protein deficiency. But, that isn’t the case at all. In fact, a protein deficiency is almost unheard of in America and only exists in someone who does not consume adequate calories. The reason this is so, is because of the macronutrient make-up of food. Food is only made up of proteins, fats, carbohydrates, and water (and sometimes alcohol). Some level of protein is present in all foods, and in significant quantities in specific types of foods such as beans and other legumes, nuts, seeds, leafy green vegetables, other vegetables and grains. The amount of protein required by the human body (5-10% of total calories per day) is relatively low in comparison to the other macronutrients. It is therefore impossible to be protein deficient when sufficient calories are consumed. This is how nature works. In reality, most people in developed countries, including those following a plant-based diet, eat too much protein, not the other way around. We clearly don’t have a health or nutritional need for whey or casein protein powders, so why are they here, why are they so popular, so common, and why is their use so infrequently questioned?” Taken from http://nutritionstudies.org/no-whey-man-ill-pass-on-protein-powder/
