One of the most commonly misunderstood topics in the world includes our macronutrients and most importantly – Proteins. Proteins are vital for the bodily functions of everyone, and that includes the healing of our muscles, strengthening of our bones, nourishment of our skin, hair and almost every other tissue in our body. Due to a wide number of misconceptions spread through the health and fitness industry, many people assume that eating meat and animal products are the only source of proteins for humans. It is true that animal products such as meat, chicken, and fish do give an adequate amount of protein, but that may not be the healthiest way for us to be ingesting proteins. When it comes to health, this is particularly important as certain groups of people such as more active people require a greater intake of proteins and having all the sources from meat itself can present health issues in the long run.

Before we began, we have to understand how proteins are made. Proteins are essentially amino acid molecules that are combined together in a long chain to create a protein molecule. Plants are special in the sense that they are able to take nitrogen in the air and break those molecules apart before rearranging themselves into amino acids and subsequently protein. It isn’t merely animal tissue that has protein, but if one consumes an adequate amount of grains and vegetables, we are able to obtain the necessary amount of protein for proper growth and development. The Health Promotion Board(HPB) recommends that an average adult would require only 0.8grams of protein for every kilogram of body weight they have. Besides that, any other additional dietary requirements that you need will depend on your personal activity.

A huge reason that many people today still think that we need to eat animals for their source of protein is because of the way media portrays protein itself. Often times, people simply assume that since fitness gurus say that eating chicken breasts and steak will give you the most protein and the least fat, they simply assume that meat and animal tissue are the only source for proteins. This is not only a serious misconception but can be costly in the long run. Instead of having meat, opt to consume more nuts, seeds, lentils, and beans. One serving of nuts and seeds can provide up to 10 grams of proteins and if you need any more of that, vegetables such as broccoli too have proteins.

In conclusion, it is important that you as a reader understand that protein sources can be varied and not come only from meat. The long-term side effects of consuming meat alone could present some really nasty side effects in your body as they are all probably carcinogens and could likely result in cancer over time. Understand your dietary requirements and take enough of only what is needed and you’ll be able to live a healthy life.
