What does the latest evidence tells us about nutrition, weight, pain, disease prevention, research and healthcare? | Image used for representational purpose only | Photo Credit: Raghu Kannan

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.

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.

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.
