Proteins are the building blocks of life. They are one of the building blocks of body tissue, and even work as a fuel source for proper development of the body.
When digested, protein breaks down into amino acids. According to the Institute of Medicine, women need a minimum of 46 grams and men require at least 56 grams of protein daily.
The main sources of protein include meats, dairy products, fish and eggs. However, this does not mean that vegetarians cannot meet their protein needs. Nearly all foods, except for highly refined food products, alcohol and oils, contain some protein.
In addition, the benefits of not eating meat for protein are numerous. For instance, it can help avoid the high saturated fat and cholesterol content in animal-based protein sources. It’s also good for the environment and helps you save money.
Several foods are high in protein content that vegetarians can easily include in their diets. While it may be difficult to get a full dose of protein per day from one source, including a few non-animal based high-protein foods in your diet can help you reach your protein goals.
