Protein Malnutrition- 2 groups
The lack of protein associated with this causes fluid to accumulate in the abdomen and fat to accumulate in the liver. Growth is impaired but because energy intake is not low the child doesn't appear extremely thin
is the depletion of fat stores and wasting away of muscle.
Why is kwashiorkor more common in children than adults?
Protein needs are higher because more growth occurs in children and therefore a deficit is more likely associated with children than adults.
What are the possible concerns with excessive protein intake?
Dehydration because when protein breakdown products must be eliminated from the urine and if there is increased protein intake then there is increased water loss in urine. This may also speed up the progression of renal (kidney) failure.
an adverse immune response to a specific food protein. Allergic reactions cause symptoms throughout the body and can be life threatening.
does not involve antibodies but causes an adverse reaction to food. ie: Upset stomach
eight common allergens which must be identified on a food label?
milk, eggs, peanuts, tree nuts, fish, shellfish, soy, and wheat
What is positive nitrogen balance?
Nitrogen intake > Nitrogen output. More protein synthesis than degradation so body is gaining protein.
When does positive nitrogen balance occur?
During growth, pregnancy, & those who increase muscle mass by lifting weights
What is negative nitrogen balance?
Nitrogen intake < Nitrogen output. Protein is being broken down more than synthesized. Body protein is decreasing.
When does negative nitrogen balance occur?
Due to injury, illness, or when a diet is too low in protein or calories.
How do you calculate an adult RDA for protein?
convert weight to kilograms (lbs x.45) by recommended amount for age group
What are the protein recommendations for endurance athletes
What are the protein recommendations for strength athletes
What is a high-quality dietary protein?
don't require you to as much to meet total protein goals.
What are common food sources for high-quality proteins?
Foods of animal origin
What is an incomplete dietary protein and where are they found?
Found in plant proteins and are more difficult to digest and are lower in one or more of the essential amino acids
Process of combining proteins from different sources so that they collectively provide the proportions of amino acids required to meet the body's needs.
What are possible benefits and concerns of animal protein sources versus plant protein sources
Benefits of animal protein more like human protein so easier to break down. Concern of animal protein can be high in saturated fat and cholesterol. Plant protein is harder for the body to break down and are lower in the essential amino acids than animal protein
