The study suggests a strong scientific rationale for the benefits of blue light-filtering in reducing vision loss.
A recent study found that consuming moderate amounts of protein per meal, around 30 grams, is most effective for building muscle. Eating larger portions does not necessarily lead to greater muscle synthesis. Shifting extra protein from dinner to lunch and breakfast may help optimize daily intake and reduce muscle loss in the elderly.
