PFAS (“forever chemicals”) are synthetic compounds used in products like nonstick pans and firefighting foams. They stick around in the body for years (half-life is approximately 5 years) and have been linked to adverse health effects, although the exact risk thresholds are still debated.
Until recently, no strategy was known to lower PFAS levels in humans.
Ultra-processed foods drive overeating, but adding protein is often marketed as a fix.
This study compared two ultra-processed diets: high protein vs normal protein (3.3 vs 1.5 g/kg/d).

Exercise stimulates the uptake of blood sugar (glucose) into the exercised muscle. But does it affect glucose uptake in other muscles that have remained rested?
It is generally assumed that solid foods are digested more slowly when compared to liquid foods. However, solid foods typically differ from liquid foods not just in food form (liquid vs solid), but also in type of protein, other nutrients, and energy content. Therefore, it was unclear if the form (liquid vs solid) as an isolated factor impacts protein digestion and absorption.

Industrial processing and storage of milk products can cause sugars to bind to amino acids, a process called protein glycation. The essential amino acid lysine is especially sensitive to this, and it’s thought that this may reduce its absorption and bioavailability.

Resistance training is currently the most effective intervention to counteract age-related muscle loss, also known as sarcopenia. However, there are large differences in muscle growth between older individuals during training protocols.
