Our new work examined whether digestive enzymes help older adults get more out of their meals. Particularly, our new study found that a multi-enzyme supplement did speed up the delivery of muscle-building amino acids (like leucine), but the results varied from person to person. Our results suggest that body composition and current diet may play a role in whether these supplements work for you (R.E., it is not a "one size fits all" solution).

Nice job MMax Deutzet al!

Recent work by our group showing that not all animal protein foods are created equal for the post-exercise stimulation of the muscle-building response. Particularly, eating a high fat ground meat matrix limited the rise in myofibrillar protein synthesis during recovery from weight lifting, likely because of a reduced leucine trigger as opposed to an acute lipid-induced anabolic resistance. More work needed in this area, but this is always a fun area of study for us. Great work by Zan!

Recent podcast discussing some of groups efforts, and others, to understand obesity-related anabolic resistance and performance nutrition related topics.

Muscle health isn’t just about how much protein you eat—it’s about how your body uses it. And for people with obesity or advancing age, that process can beco...
