New Research Finds How to Execute the Perfect Carb Load
Researchers at Liverpool John Moores University tested three two‑day carbohydrate‑loading protocols (6, 8 and 10 g per kilogram body weight) against a 4 g/kg baseline in 11 trained endurance athletes. Muscle biopsies showed a linear increase in leg‑muscle glycogen with higher carbohydrate intake, with the 10 g/kg regimen delivering the greatest storage. The study found no significant weight gain, gastrointestinal distress, or other adverse effects at the highest intake. Findings suggest that a two‑day, 10 g/kg carb load is safe and more effective than lower protocols.
New Study Finds a Common Supplement Ingredient for Cognitive Enhancement May Lead to a Shorter Lifespan
A new study of over 250,000 UK Biobank participants links genetically higher L‑tyrosine levels to a shorter lifespan, especially in men, who lived about one year less on average. Researchers used Mendelian randomization to isolate tyrosine’s effect, finding it more...
The Current Status and Emerging Trends in the Application of Precision Nutrition for the Comprehensive, Lifecycle-Based Management of Chronic Liver...
A new narrative review in Frontiers in Nutrition outlines how precision nutrition—leveraging genomics, metabolomics, gut‑microbiome data and lifestyle factors—can transform the lifecycle‑based management of chronic liver disease (CLD). The authors detail stage‑specific dietary strategies, from Mediterranean‑style low‑energy diets in early...
Effects of Low Glycemic Index/Load Diets on Metabolic and Inflammatory Markers in Humans: A Meta-Analysis
A meta‑analysis of 21 randomized trials involving 1,265 participants found that low‑glycemic index or load (LGI/LGL) diets were associated with modest weight loss, lower body‑mass index, and improvements in lipid profiles—including reductions in total cholesterol, triglycerides and LDL‑C and an...
New E-Book Is ‘Chairside Reference’ for Nutrition in Eye Care
Healio reports the release of *Ocular Nutrition Handbook for the Practicing Optometrist*, an e‑book authored by Jeff Anshel, OD, FAAO. The guide offers nutrition‑based treatment recommendations for more than 30 eye conditions, from age‑related macular degeneration to dry eye and rare...
Abbott Nutrition Study: Older Women Gain Greater Muscle Benefits From Protein Plus HMB
Abbott Nutrition funded a randomized double‑blind crossover trial that examined whether adding 3 g of β‑hydroxy‑β‑methylbutyrate (HMB) to a 40 g whey protein dose enhances muscle protein synthesis (MPS) in older adults. The study, involving 24 healthy participants aged 65‑75, found that...
Vitamin K2-7 May Slow Progression of Coronary Artery Calcification
A two‑year randomized trial (VitaK‑CAC) found that daily 360 µg of vitamin K2‑7 (MK‑7) reduced coronary artery calcification (CAC) progression by 29% versus placebo in 180 high‑risk adults. Participants had baseline CAC scores between 50 and 400, and 78% were on...
Why Tiny Amounts of Vitamin B12 Matter More as We Age
Vitamin B12, required in microgram amounts, remains essential for red blood cell formation, nerve health, and DNA synthesis. Deficiency is common among older adults, vegans, and those with absorption issues, often manifesting as fatigue, neurological symptoms, or anemia. Recent studies...
Consuming a Moderate Amount of Carbs Could Lower Cardiovascular Risk While Also Keeping 'Bad' Cholesterol Down
A new meta‑analysis of 174 trials involving 11,481 adults across 27 countries finds that moderate carbohydrate intake delivers the most balanced cardiovascular benefits. While very low‑carb and keto diets lower some risk markers, they raise LDL cholesterol, whereas moderate‑carb diets...
Effects of Beta-Alanine Supplementation on Exercise Performance and Related Physiological Outcomes in Women: A Systematic Review and Meta-Analysis
A new systematic review and meta‑analysis examined beta‑alanine supplementation in women across 12 reports (11 RCTs, 312 participants). The pooled analysis found a moderate improvement in time‑to‑exhaustion (SMD ≈ 0.49, p = 0.001) while effects on peak power, anaerobic performance, VO₂max/VO₂peak and body‑fat percentage...
An Alternative Dietary Variety Score Reflects Nutrient Adequacy Across Different Life Stages in Japanese Women
Researchers created an Alternative Dietary Variety Score (ADVS) that swaps the traditional "fats and oils" component of Japan's Dietary Variety Score (DVS) for whole‑grain consumption. Using cross‑sectional data from 4,227 young, 3,562 middle‑aged and 1,655 older Japanese women, they found...
Time-Restricted Eating and Metabolic Health: Implications for Nutritional Strategies and Weight Loss
A Frontiers in Nutrition mini‑review published on June 11 2026 evaluates time‑restricted eating (TRE) as a chrononutrition strategy. The authors synthesize clinical trials showing that 6‑10‑hour eating windows can produce modest weight loss and improvements in insulin sensitivity, blood pressure, and lipid...
Precision Nutrition in Gastric Cancer: Current Advances and Future Directions
The review in Frontiers Nutrition outlines how precision nutrition—individualized, phenotype‑driven dietary support—can address the high rates of malnutrition, weight loss, and sarcopenia in gastric‑cancer patients. It details a stepwise assessment pathway that starts with risk screening, proceeds to GLIM‑based malnutrition diagnosis,...
Gut-Lung Axis: RCT Supports Bifido Probiotic’s Immune-Supporting Benefits
A six‑month, double‑blind RCT involving 360 formula‑fed infants under three years tested Bifidobacterium animalis subsp. lactis BLa80 at 5 billion CFU daily. The probiotic group saw upper respiratory infections drop from 42.5% to 19.4% and eczema prevalence fall from 70% to 27.6%....
Single-Dose Creatine Before Exercise May Support Strength Training: Study
A randomized crossover pilot trial with 11 physically active men showed that ingesting a single dose of creatine monohydrate two hours before resistance training yielded greater acute strength performance in bench press and back squat than taking it during, after,...
