Dairy Maintains Central Role In A Healthy Diet

The new dietary guidelines released this week maintain dairy foods’ central role in American diets and highlight all it brings to the table, including high-quality protein, healthy fat, vitamins and minerals.

The guidelines continue to recommend three servings of dairy per day for those consuming a 2,000-calorie diet. They also explicitly endorse full-fat dairy consumption, including whole milk, a marked departure from previous guidelines that only recommended low- and non-fat milk. Additionally, while the new guidelines do state that one meal should contain no more than 10 grams of added sugars, the naturally occurring sugar in milk is acknowledged as not counting toward that amount.

Video: Porcine Gut Models in Nutrition Research - Dr. Li-Hsuan Chen



In this episode of The Swine Nutrition Blackbelt Podcast, Dr. Li-Hsuan Chen, postdoc researcher at Aarhus University, discusses how porcine intestinal cell lines and organoids can help study the impact of nutrition on gut health. He explains how in vivo piglet trials identify diet-driven shifts in microbiota and metabolites, while in vitro models allow researchers to test specific metabolites, barrier function, immune markers, and future organ-on-chip systems before moving back to animal studies. Listen now on all major platforms!

"In vitro models can reduce early animal use by helping researchers screen nutritional candidates before moving back to in vivo trials."

Meet the guest: Dr. Li-Hsuan Chen / li-hsuan-chen-9a95a7279 is a postdoc researcher at Aarhus University in Denmark. Research focuses on porcine gut health, host-microbe interactions, cell lines, and organoids, with PhD work at Aarhus University studying how dietary protein and amino acid levels shape gut microbiota, microbial metabolites, and intestinal epithelial responses.
