Protein requirement: As a rule, boys and girls between ages 11 and 14 need half a gram per pound of protein a day. Between ages 15 and 18, the rda drops slightly. As with all essential nutrients, common sense is the rule—you don’t have to weigh every gram on a scale. Each gram of protein provides 4 calories—the same as carbohydrates—and protein should make up about 10% to 12% of each day’s calories.

BDNF, NF-KB & more!: Since addiction involves multiple pathways in the brain and substantially cell-level changes, many proteins are under investigation for their involvement in addiction. A couple interesting ones include bdnf (a neurotrophic factor, i.e. A protein that helps neurons grow & alters their function) and nf-kappa b (a protein involved in the innate immune system, which may be activated during addiction).

How are proteins related to alzheimer's?

Dr. Mariana Dangiolo
Geriatrics 29 years experience
Alzheimer's Proteins: In alzheimer's disease, two proteins are known to accumulate and build up in the brain. One protein called amyloid β aggregates into large disruptive ‘plaques’, while tau protein forms tangled fibres within nerve cells. This excessive acummulation of proteins in the neurons eventually lead to the memory problems and cognitive decline seen in alzheimer’s.

Bioavailability: Whey protein (especially the hydrosylate and isolate processed variants) contain abundant amounts of branched chain Amino Acids in proportions compatible with the human body's needs. These serve as potent stimulators of protein synthesis and tend to be more bioavailable than traditional sources of protein (beans, legumes, etc. This is one of the reasons they're utilized by nutrition enthusiasts.

What are general exercise recommendations for young athletes with hcm?

2 doctor answers4 doctors weighed in
Dr. James Chen
Sports Medicine 15 years experience
There aren't any: It will be difficult to find specific recommendations because the first manifestation of hcm can be sudden death. 30% of people with hcm have obstruction to blood flow at rest. 10% only with rigorous activity. Noncompetitive exercise is a reasonable recommendation I have seen. However, any exercise program should be under the direction of a physician.
