Diet as a whole, encompassing food composition, calorie intake, and the length and frequency of fasting periods, affects the time span in which health and functional capacity are maintained. Here, we analyze aging and nutrition studies in simple organisms, rodents, monkeys, and humans to link longevity to conserved growth and metabolic pathways and outline their… Continue reading Nutrition, longevity and disease: From molecular mechanisms to interventions

Micronutrients and food choice: A case of ‘nutritional wisdom’ in humans?
Many reports show that non-human animals have the ability to select foods based on their micronutrient composition. However, it is unclear whether humans also have this ability, and researchers have lacked appropriate methods to investigate this question. In response to this challenge, we developed an approach that derives evidence from patterns of choices across a… Continue reading Micronutrients and food choice: A case of ‘nutritional wisdom’ in humans?
Global, distinctive, and personal changes in molecular and microbial profiles by specific fibers in humans
Dietary fibers act through the microbiome to improve cardiovascular health and prevent metabolic disorders and cancer. To understand the health benefits of dietary fiber supplementation, we investigated two popular purified fibers, arabinoxylan (AX) and long-chain inulin (LCI), and a mixture of five fibers. We present multiomic signatures of metabolomics, lipidomics, proteomics, metagenomics, a cytokine panel,… Continue reading Global, distinctive, and personal changes in molecular and microbial profiles by specific fibers in humans
Calorie Restriction with or without Time-Restricted Eating in Weight Loss
We randomly assigned 139 patients with obesity to time-restricted eating (eating only between 8:00 a.m. and 4:00 p.m.) with calorie restriction or daily calorie restriction alone. For 12 months, all the participants were instructed to follow a calorie-restricted diet that consisted of 1500 to 1800 kcal per day for men and 1200 to 1500 kcal… Continue reading Calorie Restriction with or without Time-Restricted Eating in Weight Loss
Efficacy and Safety of Vitamin D Supplementation to Prevent COVID-19 in Frontline Healthcare Workers. A Randomized Clinical Trial
Background. Associations between vitamin D (VD) deficiency and the risk of SARS-CoV-2 infection have been documented in cross-sectional population studies. Intervention studies in patients with moderate to severe COVID-19 have failed to consistently document a beneficial effect. Objective. To determine the efficacy and safety of VD-supplementation in the prevention of SARS-CoV-2 infection in highly exposed… Continue reading Efficacy and Safety of Vitamin D Supplementation to Prevent COVID-19 in Frontline Healthcare Workers. A Randomized Clinical Trial
Avocado Consumption and Risk of Cardiovascular Disease in US Adults
AbstractBackgroundEpidemiologic studies on the relationship between avocado intake and long‐term cardiovascular disease (CVD) risk are lacking. Methods and ResultsThis study included 68 786 women from the NHS (Nurses’ Health Study) and 41 701 men from the HPFS (Health Professionals Follow‐up Study; 1986–2016) who were free of cancer, coronary heart disease, and stroke at baseline. Diet… Continue reading Avocado Consumption and Risk of Cardiovascular Disease in US Adults
Effects of Caffeine Consumption on Attention Deficit Hyperactivity Disorder (ADHD) Treatment: A Systematic Review of Animal Studies
Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by a persistent pattern of inattention and/or hyperactivity-impulsivity. ADHD impairments arise from irregularities primarily in dopamine (DA) and norepinephrine (NE) circuits within the prefrontal cortex. Due to ADHD medication’s controversial side effects and high rates of diagnosis, alternative/complementary pharmacological therapeutic approaches for ADHD are needed.… Continue reading Effects of Caffeine Consumption on Attention Deficit Hyperactivity Disorder (ADHD) Treatment: A Systematic Review of Animal Studies
Reduction of dietary sodium to less than 100 mmol in heart failure (SODIUM-HF): an international, open-label, randomised, controlled trial
BackgroundDietary restriction of sodium has been suggested to prevent fluid overload and adverse outcomes for patients with heart failure. We designed the Study of Dietary Intervention under 100 mmol in Heart Failure (SODIUM-HF) to test whether or not a reduction in dietary sodium reduces the incidence of future clinical events. MethodsSODIUM-HF is an international, open-label,… Continue reading Reduction of dietary sodium to less than 100 mmol in heart failure (SODIUM-HF): an international, open-label, randomised, controlled trial
Artificial sweeteners and cancer risk: Results from the NutriNet-Santé population-based cohort study
The food industry uses artificial sweeteners in a wide range of foods and beverages as alternatives to added sugars, for which deleterious effects on several chronic diseases are now well established. The safety of these food additives is debated, with conflicting findings regarding their role in the aetiology of various diseases. In particular, their carcinogenicity… Continue reading Artificial sweeteners and cancer risk: Results from the NutriNet-Santé population-based cohort study
