Diet & Nutrition

Food and beverages provide the energy and nutrients you need to improve health, manage disease, and reduce the risk of disease. Complete nutrition requires ingestion and absorption of vitamins, minerals, essential amino acids from protein and essential fatty acids from fat-containing food, also food energy in the form of carbohydrate, protein, and fat. Dietary habits and choices play a significant role in the quality of life, health and longevity.

Dehydrated Foods: Nutrition Facts, Health Benefits, and Safety Risks

Dehydrated foods extend shelf life and improve storage stability by reducing water activity, while modern drying technologies help preserve nutrients, texture, and bioactive compounds more effectively than traditional methods. Careful control of drying conditions, packaging, and storage is essential to minimize nutrient loss, microbial risks, and quality deterioration in dehydrated fruits, vegetables, meats, and ready-to-eat foods.

The coffee advice given to atrial fibrillation patients may deserve a rethink

The DECAF randomized trial found that adults with persistent atrial fibrillation or atrial flutter assigned to drink at least one cup of caffeinated coffee daily had a 39% lower hazard of recurrent clinically detected AF or flutter than those assigned to avoid coffee and caffeine. The findings challenge longstanding advice to routinely restrict caffeinated coffee in people with AF, while further research is needed to determine whether coffee itself provides a protective effect.

How much do nuts matter for blood pressure? This study points to about a handful a day

A meta-analysis of eight prospective studies involving 143,380 participants found that higher nut consumption was associated with a lower risk of developing hypertension. Each 28 g/day increment was associated with a 20% lower relative risk in the linear analysis, while the modeled association appeared to level off at around one handful per day.

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.

Genetic analysis of 1 million people points to FNIP1 as a promising metabolic target

Mega-scale exome sequencing of 1,032,116 people identified 59 independent genes linked to the TG:HDL ratio, including 44 rare-coding associations not detected in the previous largest analysis. Ultra-rare FNIP1 loss-of-function variants were associated with favorable fat distribution, lower liver fat and glycemia, and around 60% lower odds of a composite cardiometabolic disease outcome.

Higher residential nighttime light exposure was associated with contrasting biological aging patterns in nearly 300,000 UK Biobank participants, depending on the aging algorithm used. PhenoAge and homeostatic dysregulation suggested a potentially adverse aging pattern, while KDM-BA showed the opposite association, underscoring uncertainty about how nighttime light relates to biological aging.
