Q. I enjoyed your article about saturated fats. My husband and I have been eating saturated fat and avoiding all the “white stuff” like flour and sugar. We have been separating “fuels” by having protein and fats or lean protein with healthy carbs at our meals.
I have lost 30 pounds. My cholesterol went from 204 to 160, and my triglycerides from 140 to 41.
A. For decades, nutrition scientists have told us that eating saturated fat would lead to clogged coronary arteries. This seemed logical, but it was not based on evidence.
The most recent study, called PURE (Prospective Urban Rural Epidemiology), followed more than 135,000 people for seven years. During that time, about 4,700 had heart attacks or strokes, and nearly 6,000 died. Those who consumed a high-carbohydrate diet rich in sugars and processed flour were more likely to suffer such consequences (The Lancet, online, Aug. 29, 2017).

In addition to soy, minerals such as iron or calcium and antacids such as aluminum hydroxide or magnesium hydroxide can interfere with levothyroxine absorption. You should leave at least four hours between swallowing any of these and taking your thyroid hormone.
