In 2025, J. Zeng and a team from China reviewed 9 randomized trials with 514 adults battling depression. They compared high-intensity exercise (like intense running or weight lifting) to control groups, measuring depression with standard scales like the Hamilton Rating Scale for Depression (HRSD). Workouts lasted from weeks to months.

In 2025, Jingfeng Chen and a team from Chinese universities reviewed animal and human studies on how vitamin D and exercise together help keep brains healthy as people age. They looked at things like brain growth proteins, blood flow, and swelling in the brain, focusing on older adults with memory problems.

In 2025, Elena Freire Paz and a team from the University of Santiago de Compostela studied 25 older adults in Spain (Galicia and Extremadura) using interviews and home observations from November 2024 to April 2025. They explored how loneliness affects eating habits, focusing on food choices, cooking routines, and meal enjoyment.

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, Rory Wolfe and a team analyzed the ASPREE trial with 19,114 older adults (aged 65+ for US minorities, 70+ otherwise) without prior heart issues, dementia, or disabilities. From 2010–2017, half took daily low-dose aspirin, half got a placebo, with follow-up until 2022 for 15,668 participants. They checked for heart attacks, strokes, and bleeding events.

In 2025, Stephanie Harris and team from Case Western Reserve University reviewed studies on protein needs in older adults. They found protein metabolism changes with age, leading to muscle loss and weaker immunity. In the US, 30% of men and 50% of women over 71 eat too little protein due to gut issues, less appetite, tooth problems, money worries, and loneliness.

In 2025, Changhu Sun and a team from Chengdu University of Traditional Chinese Medicine looked at data from 2,207 older adults in the US from the National Health and Nutrition Examination Survey (2011-2014). They created a score called the Dietary Index for Gut Microbiota to see how foods that help good gut bugs—like fruits, veggies, whole grains, beans, yogurt, and fish—affect thinking skills.

In 2025, Daniel S. Rubin and team from the University of Chicago studied 125 older adults (some frail) using a smartphone app to measure walking pace. They tracked steps per minute and physical abilities like balance and strength over 12 weeks.

A 2025 study analyzing 85 previous studies found that people who stay consistently active have a 30–40% lower risk of early death—especially from heart disease. Even those who start exercising later in life still see a 20–25% drop in mortality risk, showing it’s never too late to change your future.
