Beans (Mature soy beans)
Eggs
Yogurt
Milk
Nuts and seeds

Importance of proteins:
We break down proteins into their amino acid components and then rebuild them into our body proteins, which is called protein digestion and then protein synthesis.
Proteins have specific roles in the body, some proteins are involved in structural support, while others are involved in bodily movement, or in defence against germs. For example;
Antibodies defend the body from germs
Contractile proteins are responsible for movement
Storage proteins store amino acids
Enzymes speed up chemical reactions

Sporting examples of use of proteins:
Athletes need protein primarily to repair and rebuild muscle that is broken down during exercise and to help optimizes carbohydrate storage in the form of glycogen. Protein isn’t an ideal source of fuel for exercise, but can be used when the diet lacks adequate carbohydrate. This is detrimental, though, because if used for fuel, there isn’t enough available to repair and rebuild body tissues, including muscle.
Recommended Daly Protein Intake:
The average adult needs 0.8 grams per kilogram (2.2lbs) of body weight per day.
Strength training athletes need about 1.4 to 1.8 grams per kilogram (2.2lbs) of body weight per day
Endurance athletes need about 1.2 to 1.4 grams per kilogram (2.2lbs) of body weight per day
Food, Amount, Protein:

Fish, 3 oz, 21 grams

Chronic Gout Research Paper

Caucasian population and is caused by the accumulation of uric acid in various joints in the body. Gout may be chronic and reoccur frequently or may also be acute and occur infrequently. The metabolic process of purine metabolism, primarily purines derived from animal meat or from proteins endogenous to the human body, is responsible for gout. In this catabolic process, the purines are broken down into urate, and should be further metabolized to allantoin by uricase, which is quite soluble in the bloodstream…

Diseases Of The Endocrine System

by a given cell type depends upon its complement of peptide hormone receptors, its response to peptide hormone stimulation and its genetically expressed complement of enzymes. 2. Endocrine System 3. Hormones do many things. They regulate metabolism. Metabolism is all of the chemical and energy reactions that happen in a living thing. Hormones cause the growth and death of cells and of whole organisms. (Another word for a living thing like a plant or an animal is an organism.) Hormones also start…
