which micronutrient deficiencies most impair wound healing in adults?
Wound repair in adults is most sensitive to deficiencies of several micronutrients that support collagen production, immune defense, oxygen delivery, and cellular proliferation. Evidence from the Office of Dietary Supplements
are plant-based meat alternatives nutritionally equivalent to real meat?
Plant-based meat alternatives can approximate some nutritional aspects of animal meat but are not uniformly equivalent. Major nutrient categories such as protein are often matched in quantity, yet differences emerge
how does meal frequency influence fasting insulin levels in adults?
Biological basis: how eating patterns affect insulin
The concentration of fasting insulin reflects recent insulin secretion and peripheral insulin sensitivity. Meal timing and meal frequency influence postprandial insulin pulses, glycogen turnover,
how does dietary creatine supplementation affect muscle recovery in older adults?
Dietary creatine supplementation can support muscle recovery in older adults by enhancing cellular energy availability and augmenting the benefits of resistance exercise. Research led by Darren G. Candow at the
what dietary strategies promote gut barrier integrity in older adults?
Mechanisms and causes
Age-related decline in gut barrier integrity arises from interacting biological and environmental factors. Altered microbiota composition and reduced microbial diversity are common in older adults, and researchers such
when should athletes consume carbohydrates for optimal endurance performance?
Optimal carbohydrate timing for endurance depends on event length, intensity, and individual tolerance. Evidence synthesized by Louise M. Burke Australian Institute of Sport emphasizes that pre-event carbohydrate stores determine early-race
night-shift nutrition: early studies show small protein-rich snacks between shifts can stabilize blood sugar and curb cravings — what workers should try?
Early experimental work and recent controlled trials show that meal timing and portion size at night influence blood glucose and appetite. Stephanie Centofanti at the Sleep and Chronobiology Laboratory, University
which dietary patterns best preserve gut microbial diversity during antibiotic therapy?
A plant-forward, high-fiber and minimally processed diet, supplemented where appropriate with fermented foods and targeted prebiotics or probiotics, best supports gut microbial diversity during antibiotic therapy. This pattern supplies microbial
how does regular consumption of nuts affect cardiovascular risk?
Evidence and mechanisms
Regular intake of tree nuts and peanuts is consistently linked with reduced cardiovascular risk across randomized trials and large cohort studies. The PREDIMED randomized trial led by Ramón
how does meal personalization based on microbiome improve glycemic control?
Personalizing meals using gut microbial profiles improves blood glucose control by predicting and modifying individual postprandial glycemic responses. Early landmark research by David Zeevi, Eran Segal, and Eran Elinav at
