Everyday, old cells in the body are replaced with new ones.

Extracts from this document...

Introduction

Everyday, old cells in the body are replaced with new ones. FemaleMuscle.com's Tom Venuto wrote in his article, Understanding Protein, "Quantum physicists have proven that 98% of the atoms in your body are replaced within one year. In three months your body produces an entirely new skeleton. Every six weeks, all the cells have been replaced in your liver. You have a new stomach lining every five days. Every month you produce an entirely new skin"(20). To make new tissues, the body must have new protein. There are 100,000 different proteins in the human body (20); each consists of many amino acids bonded together to create long chains. Proteins serve two main purposes in the human body, structural and functional. Structural proteins form most of the human body by creating keratin and collagen, which make up muscles, skin, tendons, and hair. Functional proteins are used in bodily functions. An example is hemoglobin, a protein that transports oxygen through the bloodstream. Insulin and enzymes are more examples of functional proteins. There are 20 amino acids that form proteins; these are divided into three groups: essential, conditionally essential, and non-essential. When a protein is created, or synthesized, the needed amino acids combine at the point of synthesis. If the amino acids are not present, then synthesis cannot occur. Without protein synthesis, the body lacks proteins needed for growth(20). What are essential amino acids and why do we need them? The essential amino acids are tryptophan, lysine, methionine, phenylalanine, threonine, valine, isoleucine, and leucine. These amino acids are essential to the human diet because they are never provided in enough amounts by the metabolism. ...read more.

Middle

This meal provides 16 grams of dietary protein (17). For lunch, 1 corn taco and 1/2 cup pinto beans create a complementary protein, as well as 1/2 cup brown rice with 2 ounces tofu (7). This adds 24 grams of diet to the daily total(17). Two tablespoons (tbsp) guacamole adds flavor and 1 gram of protein (17). For dinner, a 2 ounce Tempeh burger with a sesame seed bun contains 18 grams of dietary protein (17). 2 ounces tofu yogurt with 1 ounce walnuts contains 10 grams of dietary protein (17) and is a source of complementary protein (7). Five ounces of collards provide 4 grams protein(17). Added together, day one's menu provides 73 grams of dietary protein and four sources of complete protein. For breakfast on day two, we chose 3/4 cup oatmeal and 1 ounce sunflower seeds and 1 slice whole wheat toast with 1 tbsp peanut butter. These are complementary proteins (9) and together make up 19 grams of dietary protein(17). For lunch, we chose 1/2 cup brown rice with 1/2 cup green peas along with 4 tbsp avocado, 2 ounces bean sprouts, and 2 tbsp almond butter on one whole wheat pita. All together, this makes up two complementary proteins, plenty of complete protein (9) and 27 grams of dietary protein (17). One 3 ounce tofu cutlet and 2 oz green beans with 1 ounce almonds make a complementary protein(9), and provide 19 grams of dietary protein (17). 1/2 cup whole wheat noodles with 1 ounce sesame seeds add another complementary protein(9) and provide 9 grams of protein (17). Day two's meal provides 74 grams of dietary protein and five sources of complementary protein. ...read more.

Conclusion

Too much land is being used around the world for cattle to graze on, instead of using it to grow higher-protein grain for ourselves. Both would be excellent money saving ideas, along with offering a substantial amount of complete protein to the diet. Our Suggestions to Decrease Protein Deficiencies Our suggestions to help the malnourished are to reduce production of animal products, while putting more emphasis on growing vegetables and grains. Also, every family should farm for themselves, rather than relying on the unstable market for food. We believe that too much land is being used for cattle to graze on, instead of using it to grow higher-protein grain for ourselves. When consumers buy more plant products and less animal products, this encourages farmers to use their land for farming, rather than grazing. These would be excellent money saving ideas, along with offering a substantial amount of complete protein to the diet. One of the most important things to understand about protein is that it is essential to meet human dietary needs. There are eight essential amino acids that are not supplied by the body. Therefore, we need to make sure, for the sake of our health, that we obtain these amino acids through our diet by eating the right balance of both complete and complementary protein. Through our, research we have discovered that vegan diets are just as capable as meat-consuming diets of producing the right amount of these proteins. Many countries have developed delicious and unique delicacies that contain adequate amounts of protein, both complete and complementary. By experimenting with these foods and new protein sources, we can decrease protein deficiency diseases in impoverished areas and live in a state of better health everywhere. ...read more.
