What impact does salt have on bone health?
Salt can impact calcium excretion in the urine and it is said that a high salt diet can increase risk of osteoporosis as it draws calcium from the bone and excretes it. How much of an impact does dietary salt intake actually have on bone health and how high would salt intake have to be for this to be a concern. Obviously high salt intakes are not something to aim for in general, but just wondered if this was a mechanism that could remove meaningful amounts of calcium in a way that I should be advising around this in those that we work with as nutritional professionals. Thanks!
How much Protein is Optimal and Safe for Whole Body Use
I enjoyed AMA #1 with Dr Phillips and I know he's going to cringe but I am still confused on what is considered optimal & safe to consume daily. If I have this right, 20-30 grams per meal is a target for Muscle Protein Syntheses. That suggests that much of the consumed protein could be used for muscle growth, but if that was what you were consuming and the other trillions of cells need 75% of that protein, that only leaves 5-7.5 grams from muscle syntheses. The other part of my question is how much is considered safe to consume on a daily basis. I've seen numbers ranging from about 2 grams/Kilo to almost 4 grams/Kilo. My impression is that the high limits are based on the assumption that it stresses the kidneys. I don't recall reading anything where that has actually been seen in other than people who already had compromised kidney function. Sorry my question was so long. If you use it, please paraphrase liberally.
Zinc supplementation in anemia of prematurity
Hi Danny! Paul Sharp talked about how it may be beneficial to supplement zinc with iron for anemia. Would this be helpful in cases of anemia of prematurity? We routinely give iron supplementation to prevent this but I’m wondering if the addition of zinc would also be beneficial to prevent anemia in preemie babies.
Organic meat
Many of my friends wouldn't eat non organic food and have perception that it is bad to eat non organic foods (pesticides etc.). I know that there is no strong evidence proving this, but is there any other strong argument against this? Also, I have heard a lot of bad stuff about non organic meat, especially chicken - it is high in saturated fat, contains antibiotics, hormones etc. Could you clarify this please? Thanks!
