  1. Erika Johnson THE IMPORTANCE OF PROTEIN IN THE DIET

  2. WE KNOW THIS! Amino Acids are the building blocks which provide the ‘raw material’ for all proteins. After a protein is ingested, digestive enzymes break the protein down into AA. These then enter the bloodstream and travel to the cells where they are incorporated into the proteins that the body needs. … What exactly are our body’s protein needs? AMINO ACIDS

  3. COMPLETE VS INCOMPLETE • Incomplete proteins lack or contain only a very small proportion of one or more EAA • Protein found in foods such as grains, fruits, and  vegetables are either  low,  are considered incomplete proteins In terms of nutritional needs, protein comes in two forms. COMPLETE PROTEINS contain all 8 EAA that humans cannot otherwise produce  all meat and other animal products are sources Humans can make use of all the AA that they extract from food. They use these to make new proteins but the IEAA need not be supplied with our diet but EAA must be! answerfitness.com

  4. BIOLOGICAL VALUE • Whey protein and eggs both have a high biological value (BV). Eggs BV is almost 100% and this in addition with the health benefits in the yolk of the egg has earned it the nickname of the “perfect food” • A high BV means that the amino acid ratio is excellent for building muscle and that a large proportion of the protein consumed is absorbed and utilized by the body. • Additionally, numerous studies from reputable researchers have shown that whey has immune-system enhancing benefits.

  5. The average individual needs 50-60 grams of protein each day. 1.1-1.5 g/kg of body weight In  addition to meat, poultry and fish, significant  amounts of protein are found in beans, milk,  eggs, dairy foods, seeds,  nuts, grains and soy  products. WHEY: The primary difference between isolate and concentrate is that the isolate is more pure. Isolate contains more protein with less fat and lactose per serving. Whey isolate usually contains between 90-94% protein while whey concentrate has a protein ratio of 70-85%. REMEMBER: When  protein is listed on a nutrition label it  only refers to the amount of complete proteins in the food. Search for foods with a high BV or combine proteins to complement one another FOOD FOR THOUGHT

Journal of Sports Sciences Volume 29, Supplement 1, 2011 Special Issue: Supplementary Issue: IOC Conference on Nutrition in Sport, 25-27 October 2010, International Olympic Committee, Lausanne, Switzerland Athletes seeking to gain muscle mass and strength are likely to consume higher amounts of dietary protein than their endurance-trained counterparts. The main belief behind the large quantities of dietary protein consumption in resistance-trained athletes is that it is needed to generate more muscle protein. Athletes may require protein for more than just alleviation of the risk for deficiency, inherent in the dietary guidelines, but also to aid in an elevated level of functioning and possibly adaptation to the exercise stimulus.
