We all need a continuous source of protein in our daily diet. Bodybuilders and athletes cannot live without it. As our society becomes more aware and healthier, we take more care of ourselves than we eat.
Good health begins with diet. For centuries, the main source of protein for most humans has been animal protein. That is still true today, the only protein most of us digest is exclusively from animals.
Meanwhile, doctors are concerned about the side effects of excessive amounts of this protein due to the high concentration of fat associated with high blood pressure, heart disease and high cholesterol, among other problems.
That doesn't mean that animal protein is totally bad. But it is healthy to know that there are other sources of protein besides meat and dairy. For example, whey protein¹ and soy protein are two excellent sources of the much-needed protein that our bodies need.
What are the differences between Whey Protein and soy protein?
Soy beans are rich in protein and offer an abundant number of amino acids. Soy is considered a complete source of protein. Because of this, soy is an excellent source of protein for vegetarians or people who want to cut down on meat. The quality of soybeans has been shown to be able to lower cholesterol.
According to the American Heart Association, 25 to 50 grams of soy protein a day can reduce the chances of developing heart disease. Other research has shown that soy can prevent breast cancer and osteoporosis. For women, this is good news. But soy is not man's best friend. Not at all.

The fact is, soy is loaded with estrogen . When consumed regularly, especially in high doses, soy can cause profound changes in man. There are mainly two chemicals in soy: daidzein and genistein.
So similar in nature to oestrogen, these two ingredients are called phytostrogens, which are plant-based estrogens. Among the side effects that a man can suffer from excess oestrogen is sensitivity in the pectoral area, change in emotions and reduced sexual performance, basically a reduction in libido.
It can also cause infertility in men. Physical changes can also occur, with a condition called gynecomastia, which is a strong growth of the mammary glands in men due to abnormal amounts of estrogen. In simple terms, it makes male breasts grow.
Important observation for bodybuilders
Soy protein contains trypsin inhibitors that block enzymes essential to digest the protein. These inhibitors can cause gastric upset and interrupt the use of amino acids, leading to deficiencies. Some of these inhibitors can be removed by a high temperature process. Meanwhile, this process can break down any of the beneficial elements that soy protein contains.
Whey protein is the highest quality protein product available and an essential source of amino acids. It is derived from milk. More specifically, whey protein is a residue from processed milk cheese. There are two types of whey protein, concentrated and isolated.
Whey concentrate is about three-quarters of pure protein by weight. On the other hand, isolated whey is an even purer form of whey protein. Fat and lactose are removed in the whey process alone, and the result is a product that is basically 90% pure protein. That is a great option for people who are concerned about the fat concentrations associated with animal protein.
What is the use of Whey Protein?
Compared to other forms of protein, whey protein is the best. Whey protein provides the body with essential amino acids for gaining lean mass, increasing strength and reducing muscle recovery time.
Whey protein helps with weight loss. According to a study of 158 people, published in Nutrition & Metabolism, those who received it lost significantly more body fat and showed greater preservation of muscle mass.
For bodybuilders and professional athletes, it is the most important element of their diets, making them bigger, stronger and faster. Medical studies are ongoing with whey protein and its benefits discovered in other areas of body health. Some of the applications include weight loss and cancer treatment.
What are the benefits of whey protein?
· Rapidly increases muscle mass.
· Reduces recovery time.
· It does not contain estrogen.
· Reduces blood pressure and the risk of cardiovascular diseases.
What are the side effects of whey protein?
There are no reports of side effects. Meanwhile, if a person is allergic to lathionium, they should consult a doctor before adding whey protein to their diet. Adequate hydration is the most important because a large amount of water is needed to metabolize whey protein.
Positive points of soy protein
· Fat content.
Negative points of soy protein
· It produces large amounts of estrogen, which causes side effects in men.
· Unfermented soy products, such as soy milk and soy protein supplements, contain large amounts of toxins, especially phytic acid, so soy should not be consumed in large quantities.
Positive points of whey protein
· Build muscles quickly.
Easy assimilation by the body.
· Helps balance blood sugar levels.
· rise the levels of energy.
· Increase metabolism.
· Faster muscle repair.
Negative points of whey protein
Quality whey protein products tend to be more expensive than other products.
Blood pressure is measured by systolic over diastolic pressure. Systolic refers to the pressure when the heart is beating, and diastolic refers to the pressure when the heart rests between beats. For an average adult, a blood pressure reading is considered normal if it’s below 120/80 mmHg.
