Question: How can I protect against oxalates?

Short Answer: Getting 300-400 mg calcium between food and supplements at each meal will minimize oxalate absorption. Maintaining postprandial urine pH in the 6.4-6.8 range by getting 3-5 grams of potassium per day from food or from organic acid salts such as potassium citrate will prevent its crystallization in the kidney. Reducing dietary oxalate will prevent any possible damage in the gut.

Question: Why should postprandial blood glucose be kept under 140 milligrams per deciliter?

Short Answer: When blood glucose rises above 140 mg/dL, this is the approximate point at which it spills into the polyol pathway at a greater-than-normal rate, which represents a suboptimal state of metabolism that is likely to hurt antioxidant status and compromise detoxification pathways as well as the recycling of vitamin K and folate. It must be kept in mind that a healthy person will adapt to glycemic loads they consume regularly. Thus, a one-time spike above 140 mg/dL should never be used to conclude anything whatsoever. Only repeated spikes above this level with repeated consumption of the same glycemic load over several days to several weeks should be used as a cause for concern.

Question: What is the relationship between copper and estrogen?
Short Answer: Estrogen moves copper from the mother’s bloodstream to the fetus during pregnancy. Its action at the intestines is poorly understood but I believe estrogen and progesterone interact to promote intestinal copper absorption. Maintaining pregnancy-level hormones while not pregnant poses a risk of promoting too much absorption of copper from food without transferring it to a growing baby. Copper status should be monitored when using supplemental hormones to avoid copper toxicity.
