Why the veganism?

I decided to eliminate dietary sources of cholesterol in order to lower my husband's blood cholesterol levels.

Back in May, a blood test showed that my husband had pretty high cholesterol. The doctor gave us a couple months to reduce the number by diet without statins. Statins are a class of drugs that lower cholesterol by inhibiting HMG CoA reductase, which is the enzyme that catalyzes the rate-limiting step in cholesterol biosynthesis.

That's right, the body has the ability to synthesize the cholesterol it needs for stuff like cell membrane components and hormones. The body has to balance cholesterol biosynthesis with incoming dietary cholesterol, a process called cholesterol homeostasis. What are dietary sources of cholesterol? Anything animal-derived. For the ovo-lacto veggie husband, this meant no more eggs or dairy. So I figured it was time to eliminate dietary cholesterol and see what the husband's baseline cholesterol numbers would be.

I put myself on the diet, too, for solidarity. It's important to have a good support structure at home with any significant diet change.

Next time: Details of the diet!
