Why pulses could play a bigger role in healthy and sustainable diets

A narrative review finds that pulses may support gut and metabolic health through their fiber, protein, phytochemicals, and interactions with the gut microbiota, while offering a lower environmental footprint than many animal protein sources. Human evidence is strongest for selected cardiometabolic outcomes, while many microbiome and fermentation-related benefits remain supported mainly by animal and laboratory studies.

Restricting select amino acids may mimic protein restriction’s healthy aging benefits

A review finds that restricting protein, particularly methionine, isoleucine, and valine, may improve metabolism and influence key aging pathways, largely in experimental models. Short human studies suggest metabolic benefits, but effects on lifespan remain unknown and restriction may harm people with unmet or increased protein needs.

Consuming less protein could have greater health benefits and extend lifespan

Protein-fortified foods are popping up everywhere, from cereal and coffee to even protein water. But a new review covering over 350 papers on protein restriction and aging-publishing July 31 in the Cell Press journal Cell Press Blue-suggests that consuming less protein could have greater health benefits and could, in some cases, extend lifespan.

Dutch study shows why plant-based eating can miss key nutrients

A Dutch dietary modeling study found that replacing major animal-based protein sources with plant-based substitutes reduced protein, EAA, vitamin, and mineral intake across age groups. Older adults, adolescents, children, and women were especially vulnerable to shortfalls, highlighting the need for planned substitutions, fortified foods, and age-specific dietary guidance.

USC study links modified Mediterranean diet to longer lifespan

A plant- and fish-based, low-protein diet paired with small amounts of an amino acid commonly found in eggs, meat and dairy increased healthy lifespan and decreased frailty and fat mass in mice, according to a new USC study published today in the journal Cell Metabolism.

A review of methionine dependency in modern cancer therapy

Methionine restriction (MR) has shown significant promise in cancer therapy because it targets the unique methionine dependency of many tumors. However, despite extensive research on MR, a clear synthesis of preclinical findings and their translation into clinical settings is lacking. This review aims to address this gap by consolidating existing evidence, identifying challenges, and highlighting opportunities for advancing MR as a viable cancer treatment strategy.

Why the form of vitamin B12 you take may matter more than your intake

This comprehensive review examines vitamin B12 absorption, physiological roles, deficiency states, and dietary sources, with particular attention to differences between natural and synthetic forms. The authors conclude that while all B12 forms raise circulating levels, methylcobalamin may offer advantages in specific clinical contexts, especially where absorption or metabolic conversion is impaired.
