Solution
The answer is "isotopes and more accurate muscle biopsies". During the 1950s and 60s, the field of nutritional sciences saw significant advancements due to the introduction of isotopes and more accurate muscle biopsies. These methods allowed for more precise investigations into the effects of nutrition on the human body. Isotopes, or variants of a particular chemical element, were used as tracers to study metabolic processes. Muscle biopsies, which involve taking a small sample of muscle tissue for examination, also became more accurate, allowing for better analysis of muscle metabolism and the effects of nutrition on muscle health.
