The Sherwin Summary

Chapter Six

Sherwin how are proteins different to carbohydrates and lipids? Protein is an organic compound composed of carbon, hydrogen, oxygen and nitrogen. It is the nitrogen forming amino acid groups that chemically distinguish proteins from other nutrients. Sherwin are proteins really that complex? Each protein can contain about 20 amino acid groups and each of those amino acid groups have another side group or side chain attached to them. Sherwin what is the ultimate goal that the body goes through after eating foods containing protein? Enzymes help break down their long stranded bonds into the simpler form of amino acids and all this begins inside the stomach. Sherwin when does the absorption of amino acids take place? Intestinal cells absorb amino acids once they are made available inside the small intestine.

Sherwin how many different kinds of proteins can be found in a human body? The body has been estimated to contain about 10,000 to 50,000 proteins and with research can help define each one. Sherwin are proteins important? They have many roles inside the human body such as growing, repairing and replacing tissue. Sherwin can you list these protein functions found in the body? Growth and maintenance, enzymes, hormones, fluid balance, acid-base balance, transportation, antibodies and energy. Sherwin how do vegetarians meet their protein needs? They can eat a variety of foods such as whole grains, legumes, seeds, nuts and vegetables.

Sherwin did you know that researchers have provided different measures of protein quality? They have amino acid scoring, biological value, net protein utilization, protein efficiency ratio and PDCAAS (protein digestibility-corrected amino acid score). Sherwin how come there are protein regulations for food labels? These food labels help in dealing with malnutrition worldwide by giving out quantifiable information of digestibility and its ability to support growth. Sherwin what is the most prevalent form of malnutrition in the world called? People who are deprived of protein and energy results into protein-energy malnutrition (PEM). Sherwin can excess amounts of protein cause health problems? Over-consumption can lead to heart disease, cancer, adult bone loss (osteoporosis), weight control and kidney diseases.

Sherwin are there recommended intakes of protein? Here are daily recommended food intake percentages of nutrients; 30% fat or less, 55% carbohydrate or more and 15% protein. Sherwin did you know that dietary supplements of amino acids can be inappropriate and harmful? You need to physically train your muscles because protein supplements do not build muscle and are considered dangerous. Sherwin how do people become categorized as vegetarians? They are labeled as such because they choose to exclude foods they eat like red meat, chicken, fish, eggs, milk and milk products. Sherwin are there health benefits in having a vegetarian diet? They can maintain a healthier body weight, healthy blood pressure, suffer fewer diseases than meat eaters and have lower mortality rates linked to cancer than others.
