Current dietary zinc intake has a greater effect on fractional zinc absorption than does longer term zinc consumption in healthy adult men.

Background: No studies have examined the independent effects of current and longer-term dietary zinc intakes on zinc absorption.

Objective: We determined the effects of current compared with longer-term zinc intake on fractional zinc absorption (FZA).

Design: We studied 9 men whose usual zinc intakes were >11 mg/d.

Hepatic de novo lipogenesis in normoinsulinemic and hyperinsulinemic subjects consuming high-fat, low-carbohydrate and low-fat, high-carbohydrate isoenergetic diets.

Background: Hypertriglyceridemia is associated with increased risk of cardiovascular disease. Until recently, the importance of hepatic de novo lipogenesis (DNL) in contributing to hypertriglyceridemia was difficult to assess because of methodologic limitations.

Objective: We evaluated the extent of the contribution by DNL to different conditions associated with hypertriglyceridemia.
