Food
Food is the foundation of health and daily mood. Research highlights the importance of proteins, the risks of ultra-processed foods, and evidence-based ways to optimize metabolism and energy.

Plant protein and fish are linked with longer life, while red and processed meat raise risk
A recent media claim said that eating a lot of animal protein speeds aging. The idea has some truth, but…
Ultra-processed foods are linked to more fat inside thigh muscles
In 666 adults around age 60, those who ate more ultra-processed foods had more fat inside their thigh muscles on MRI, independent of weight, calories and exercise. Muscle strength was not measured.
videoMeal timing and food choices that support health
Intermittent Fasting (IF): Eating within a restricted time window, like 16–20 hours of fasting daily, helps activate longevity pathways, reduce…
Not smoking, exercise and varied food raise odds of living to 100
In a Chinese study of adults over 80, those who did not smoke, exercised, and ate a varied diet had 61% higher odds of reaching 100. Healthy habits still seem to count late in life.
Diet plays a bigger role in weight loss than exercise
Role of physical activity in weight loss for people with obesity remains modest but beneficial Exercise, particularly aerobic training, contributes…

Three evidence-based rules that help people lose fat sustainably
A doctor's approach to losing fat: maintain a sustainable calorie deficit, prioritize protein at every meal, and focus on lifestyle fit over diet perfection.
PAHs in food form during high-heat cooking
PAHs can form in food during smoking, grilling, and other high-heat processes. A 2025 paper mainly validates a faster lab method to detect eight PAHs in food matrices, rather than proving that everyday foods are broadly dangerous.
videoPeople who keep lost weight off stay active about an hour a day
Most lost weight returns within a few years. People who keep it off report about an hour of activity a day, and an eight-month trial found cardio cut more body fat than weights, which mainly added muscle.
Dinner at 10 pm instead of 6 pm raises blood sugar by 18%
In a lab trial, the same dinner eaten at 10 pm instead of 6 pm raised blood sugar by 18% and cut fat burning. A second trial found that late meals raised hunger and lowered calories burned.
Governments should tax ultra-processed foods like instant noodles and ice cream to protect health, says leading doctor
Ultra-processed foods, called UPFs, are factory-made products that use additives such as emulsifiers, colorings, and flavorings to improve taste, texture,…

Carbonated drinks satisfy because the mouth turns CO2 into acid
An enzyme in the mouth turns the CO2 in carbonated drinks into acid, which triggers pain nerves and sour-taste cells. Bubbles add to the sting, and in thirsty adults fizzy water quenched thirst better than still water.
A researcher wants tobacco-style health warnings on ultra-processed food packaging
A leading scientist calls for tobacco-style warning labels on ultra-processed foods due to their harmful health effects. These foods, linked…

Intermittent fasting shifted brain activity and gut bacteria
In a 2023 Chinese study of 25 adults with obesity, two months of intermittent fasting came with weight loss, lower activity in brain areas tied to eating, and gut bacteria shifts that tracked them. No comparison group was used.
