What we eat, when we eat and how we manage our weight remain important questions in health, even as advice often runs ahead of the evidence. This week,I examine one deceptively simple question: is there a right time to have dinner?
Does eating late really affect our health? Is the time at which we eat more important than what we eat? And how should dinner timing be considered alongside sleep, work schedules, physical activity and the overall quality of the diet? Doctors explain what we know about meal timing, and what it can and cannot tell us about maintaining good health.
Close on the nutrition and weight-management front is a study from the ICMR-National Institute of Nutrition, which looks at what works better for lasting weight loss. The study finds that combining diet and exercise is more effective for sustained weight loss than either approach alone. The findings are a useful reminder that weight management cannot be reduced to one food, one nutrient or one short-term intervention.
Meanwhile, the focus on protein continues to grow, particularly on social media. But increasing protein intake is not, by itself, a definition of a healthy diet. Ramya Kannan looks at what constitutes a wholesome meal and the importance of considering the overall dietary pattern rather than focusing on individual nutrients or products.
Emerging research
From everyday nutrition, we move to some interesting areas of emerging research.
Researchers are exploring whether material derived from menstrual blood could have applications in the treatment of osteoarthritis. A recent study as reported by Manjeera Gowravaram examined extracellular vesicles derived from menstrual blood stromal cells and their effects on processes involved in cartilage formation. The findings are from laboratory research and do not establish a treatment for osteoarthritis, but they add to growing interest in regenerative approaches to cartilage damage.
Another study reported by Anirban Mukhopadhyay takes a closer look at the genetic basis of cerebral palsy. Researchers found that far fewer genes may have a clear and reproducible association with the condition than some earlier studies had suggested. Understanding which genetic findings hold up is important not only for research but also for how clinicians interpret genetic information in people with cerebral palsy.
Diagnosis and care
There are also important questions about what happens within the healthcare system after patients seek care.
Dr. Suvira Jain writes about why one in three donated corneas is wasted. Eye donation does not automatically translate into transplantation. The cornea has to be retrieved, assessed, preserved and transplanted within the appropriate window. Gaps at different stages can mean that donated tissue is ultimately not used, even as many people continue to wait for corneal transplants.
Pain, too, can persist long after the original injury or illness has apparently healed. Persistent pain may require specialised assessment rather than being dismissed as something a patient simply has to live with. Afshan Yasmeen looks at why persistent pain can be complex and why appropriate pain management needs to go beyond treating the original condition.
Prevention and public health
On the disease prevention front, rabies remains an important public-health concern. Maya C. reports a study from Keralam that looks at the potential impact of dog vaccination in preventing rabies, underlining the importance of controlling the disease in its animal reservoirs alongside ensuring timely post-exposure care for people. Rabies prevention cannot depend on treating people after exposure alone; sustained vaccination and surveillance of dogs are central to controlling transmission.
The issue of counterfeit medicines also highlights why the quality and safety of healthcare products matter. A large stock of suspected counterfeit medicines was seized from a private facility in Bengaluru. Such cases raise concerns that go beyond regulation: a medicine that does not contain what it claims to contain, or does not meet required quality standards, can result in treatment failure and expose patients to further harm.
Air pollution remains another persistent health concern. A study examining winter pollution in north India finds that western disturbances explain a substantial share of the year-to-year variation in winter pollution. Weather systems are only one part of the pollution story, but understanding their role can improve forecasting and help strengthen public-health responses during periods when pollution levels are expected to rise.
Muscle metabolism, healthy ageing
For this month’s Nobel feature we look back at the work of Archibald V. Hill and Otto Meyerhof, whose Nobel-winning research helped establish how muscles generate and use energy. Their independent work helped explain fundamental aspects of muscle metabolism and the relationship between oxygen use, energy production and muscular activity.
And Health Wrap, Episode 50 looks at longevity and the role of racquet sports in healthy ageing, Navin Gnanasekaran, longevity physician and head of radiology, Apollo Hospitals, talk about healthspan, nutrition, sleep, muscle strength, stress, metabolism, inflammation and cognition. The conversation also looks at how racquet sports can bring together physical activity, social interaction and cognitive engagement, making them an interesting part of a broader discussion on maintaining health as we age.
