Scientists link emulsifiers in processed foods to allergy and immune disorders

Review identifies common food additives in ultra-processed foods—particularly emulsifiers like carrageenan and polysorbate 80—as key drivers of gut dysbiosis, inflammation, and allergic diseases by disrupting intestinal barriers and activating proinflammatory pathways.

The best diet for aging well, backed by a 30-year study of 100,000 people

A 30-year study of over 100,000 U.S. adults found that consistent adherence to healthy dietary patterns, especially the AHEI, was strongly linked to successful aging. Diets rich in plant-based foods and healthy fats, with some low-fat animal products, improved physical, mental, and cognitive health.

A pecan a day keeps bad cholesterol away

Daily consumption of 57g of pecans for 12 weeks improved cholesterol profiles and diet quality in adults at risk of cardiometabolic disease, without affecting vascular health. Replacing typical snacks with pecans led to higher intake of healthy fats and fiber, and reduced carbohydrate consumption.

Red wine lowers bad cholesterol but doesn’t improve overall heart health

Moderate red wine consumption is linked to a small but significant reduction in LDL cholesterol, according to a systematic review and meta-analysis of 33 studies. However, the study found no consistent effects on HDL, triglycerides, total cholesterol, or fibrinogen.

Waist circumference identified as a stronger cancer risk marker in men

Body size and excess weight, conventionally assessed using body mass index (BMI), are well-established risk factors for many types of cancer. However, new research to be presented at this year's European Congress on Obesity (ECO 2025, Malaga, Spain, 11-14 May) and published in The Journal of the National Cancer Institute shows that waist circumference (WC) is a stronger risk marker than BMI for developing obesity-related cancers in men, but not women.

7-day creatine ‘wash-in’ boosts muscle mass in women — but not long-term, study reveals

A 7-day creatine monohydrate wash-in increased lean body mass in females, especially in the trunk, but adding creatine to resistance training didn’t boost muscle gains beyond training alone. Higher doses or hydration tracking may be needed for long-term effects.

Sticking to Life’s Essential 8 slashes cancer risk, major study shows

Long-term adherence to the American Heart Association’s “Life’s Essential 8” lifestyle score significantly reduces the risk of overall and site-specific cancers. Stable high LE8 scores over four years were linked to notably lower risks of lung, breast, liver, and colorectal cancers in a large Chinese cohort study.
