In 2025, Anni Vanhatalo and a team from the University of Exeter studied 24 older adults (aged 60-75) in a 2-week trial. Participants drank nitrate-rich beetroot juice (140 mL/day, ~400 mg nitrate) or a placebo juice, and researchers measured blood pressure, oral bacteria, and blood vessel health using standard tests.

In 2025, Jiping Chen and Jiawei Yao from Shandong University and Guangdong Vocational Academy of Art reviewed how the ketogenic diet (KD)—low-carb, high-fat—helps manage metabolic syndrome (MetS), a mix of high blood pressure, high sugar, big waist, high triglycerides (TG), and low good cholesterol (HDL). They looked at how KD boosts ketone bodies like β-hydroxybutyrate (β-BHB) to burn fat, improve insulin use, fix lipid levels, and cut swelling.

In 2025, health experts from EatingWell reviewed studies on walking after eating. They looked at how even a short stroll, like 15-30 minutes, can help people with or without diabetes by preventing blood sugar spikes, easing digestion, and more. Research showed walking right after meals lowers glycemic response better than before, cutting blood sugar rises by 20-30% in some cases.
