Grass-Fed Beef

Grass-fed beef delivers 26g of complete protein per 100g and the highest natural creatine and carnosine content of any food. Its superior omega-3 to omega-6 ratio and 200% more conjugated linoleic acid than grain-fed beef provide additional health benefits, though debates about red meat and cardiovascular risk persist. At $5.50 per 100g, it costs 40% more than sardines but offers unique muscle-supporting compounds.
