Dairy Foods: Is Its Cardiovascular Risk Profile Changing?

Area of Science:

• Cardiovascular disease research
• Nutritional science
• Dietary guidelines

Background:

• International guidelines historically advised limiting full-fat dairy due to saturated fat content for cardiovascular disease (CVD) prevention.
• Recent studies present conflicting evidence, prompting a re-evaluation of dairy's role in health.
• Understanding the complex composition of dairy foods has shifted perspectives.

Purpose of the Study:

• To review current evidence on dairy consumption in relation to cardiovascular disease (CVD) and type 2 diabetes (T2D).
• To analyze how recent findings impact existing dietary recommendations for dairy intake.
• To provide updated insights for healthcare professionals and the public.

Main Methods:

• Review of major cardiovascular society guidelines.
• Inconsistent interpretation of large observational studies on dairy consumption.
• Analysis of associations between specific dairy products and health outcomes.

Main Results:

• Consumption of fermented dairy products, particularly yogurt, shows an inverse association with CVD and type 2 diabetes (T2D).
• While reduced-fat dairy is still preferred for those at high CVD risk, the view on full-fat dairy is less unanimous.
• Cheese and fermented milk consumption may be increased due to their nutritional benefits.

Conclusions:

• Updated advice on dairy consumption is emerging based on new evidence.
• Yogurt and other fermented dairy products show potential benefits for CVD and T2D.
• Dietary recommendations for dairy should consider the type of product and individual health status.
