Background: Dairy intake has been associated with varying impacts on circulating cholesterol concentrations across nutritional epidemiology and intervention studies, with findings attributed mainly to differences in the nature of dairy products consumed or study designs. The contribution of the genomic architecture to such observations has yet to be revealed.

Objective: We assessed the impact of multiple common genetic variations in cholesterol-related genes on responses of serum cholesterol to the recommended amount of dairy product intake in Canada.

Article Synopsis
  • Dairy products contain various fatty acids that can impact heart health, but how quickly these affects show in blood is still unclear.
  • A study with 124 healthy participants evaluated the effects of consuming dairy versus control foods over 4 weeks, measuring changes in fatty acids and lipid profiles.
  • Results showed that dairy intake raised certain fatty acids (pentadecanoic and heptadecanoic acids) and LDL cholesterol levels, suggesting these fatty acids could be markers for short-term dairy consumption.

Background: Randomized controlled trials specifically designed to assess inflammation-related outcomes in response to dairy consumption are lacking.

Objective: We investigated the impact of dairy food consumption on biomarkers of inflammation in healthy men and women with low-grade systemic inflammation.

Methods: In a multicenter randomized crossover study, 112 adult men and women with high-sensitivity C-reactive protein (hs-CRP) values >1 mg/L consumed 3 servings/d of dairy (375 mL low-fat milk, 175 g low-fat yogurt, and 30 g regular-fat cheddar cheese) or energy-matched control (fruit juice, vegetable juice, cashews, and 1 cookie) products as part of prudent 4-wk diets, each separated by a 4- to 8-wk washout period.

Background: Whereas the negative effect of consuming trans fatty acids found in partially hydrogenated vegetable oils on cardiovascular disease (CVD) risk is well established, the effect of trans fatty acids from ruminant sources (rTFAs) on CVD risk factors has not yet been established, particularly among women.

Objective: We investigated the effects of a butter naturally enriched in rTFAs, of which vaccenic acid is the predominant isomer, on plasma lipid concentrations among healthy women.

Design: In a double-blind, randomized, crossover controlled study, 61 healthy women aged 19-70 y were fed 2 isoenergetic diets lasting 4 wk each.
