Focus: Meat nutrient density and label verification
Lucas Krusinski is a food scientist who researches the nutritional composition of meat. His work examines how cattle diet and production practices affect nutrient density, including omega-3 fatty acids and plant-derived compounds. He argues that labels like grass-fed do not guarantee a specific nutrient level and favors testing and verification of nutritional claims.
Expert discussions with Dr. Lucas Krusinski
Do grass-fed labels really mean more nutritious meat?
Grass-fed labels describe how an animal was raised, not how nutritious the meat is. A food scientist explains that omega-3 fats and other helpful compounds in beef vary widely, even between products with the same label. These are different kinds of claim: an EU 'source of omega-3' label requires a set minimum amount of omega-3, while 'grass-fed' only describes how the animal was fed and guarantees no nutrient level. So the label alone is a weak guide to what is actually in a given cut. A different nutrient profile is also not the same as being 'more nutritious' overall.
