Not all Protein is created equal!

Food provides us with roughly 20 amino acids, most of which are non-essential since our body can make it for itself! However, there are 9 essential amino acids which our body cannot make on it’s own. Unlike the fats and carbs that we consume, these amino acids are not stored in the body. In other words, we must consume a constant and steady supply of the protein rich foods which contain these 9 essential amino acids.


What do you think is the best source of dietary protein? Animal or vegetable sources? As you may have guessed, not all protein is created equal and the quality of one’s dietary protein, in large part, determines how well a child will grow and develop, and how well an adult will maintain his or her health. In other words, high quality protein sources provide enough of the essential amino acids needed to support the body’s daily job of keeping us strong and healthy, while lower quality protein simply does not.


There are 2 key factors that effect the quality of the protein:

1) Digestibility

2) Composition of amino acids


The digestibility of protein is a measure of the amount of amino acids absorbed from a given protein intake, and amino acid composition refers to the simultaneous availability of all the needed amino acids from a food we choose to eat.


In general, animal-sourced proteins (meat, fish, poultry, eggs and dairy) are considered high quality proteins, as is soy, a vegetable sourced protein. However, other sources of vegetable protein tend to be of a lower quality and are often referred to as incomplete proteins because they don’t provide all the essential amino acids the body needs.


When it comes to a healthful protein, it’s also important to pay attention to what comes along with the protein in your food choices. For instance, an 8 ounce steak is a great complete source of protein with about 54 grams but it also delivers 44 grams of fat, of which 16 grams are saturated fats. Saturated fats raise blood cholesterol which ultimately increases your risk of heart disease. On the other hand a cup of cooked lentils has 18 grams of protein but less than 1 gram of fat. The best animal protein sources are fish and poultry.


Vegetable sources of protein, including soy protein beverage mixes, are also an excellent choice, and many also provide healthful amount of other essential nutrients such as fibre, vitamins and minerals.


There are soy based protein beverages which not only give you all 9 essential amino acids and other nutrients, but also help you to release and maintain a healthy weight. Please contact me if you want to know what soy protein beverage I use based on my research.
