The Food Matrix: More Than The Sum of its Nutrients

Matthew Pikosky, PhD, RD Nebraska Academy of Nutrition and Dietetics April 24, 2020 Objectives

1. Describe the emerging concept of the food matrix and how unique combinations of nutrients and bioactives work together in synergy to impact health

2. Discuss the unique components of the dairy matrix

3. Provide examples of scientific research that supports consuming dairy foods (e.g., milk, cheese, yogurt) is linked to lower risk of cardiovascular disease and type 2 diabetes, as well as improved bone health

Vitamin A is naturally occurring in whole milk and added to reduced, low-fat, and fat-free milks. Iodine is found in milk due to milking process.

Randomized crossover control trial n= 17 healthy adults Consumed 0.5 L/d of either milk “…The content of calcium and protein were similar in the two milk types, but whole milk has a higher content of milk fat globule membranes (MFGM), which encloses the fat…. Thus, one could speculate that an expected higher LDL cholesterol concentration after whole milk may be modified by a dairy matrix effect of MFGM.”

“Sustainable Diets are those diets with low environmental impacts which contribute to food and nutrition security and to healthy life for present and future generations. Sustainable diets are protective and respectful of biodiversity and ecosystems, culturally acceptable, accessible, economically fair and affordable; nutritionally adequate, safe and healthy; while optimizing natural and human resources.”

• Between 2005 and 2015, North America reduced on-farm GHG emissions intensity by 20%

• Producing milk in 2017 involved 30% less water, 21% less land, 20% less manure and 19% smaller carbon footprint than 2007
