Healthy diet
A healthy diet contains a balance of food groups and all the nutrients necessary to promote good health. Human nutrition is enormously complex and a healthy diet may vary widely according to an individual's genetic makeup, environment, and health. Healthy eating is the practice of making choices about what and/or how much one eats with the intention of improving or maintaining good health. Typically, this means following recommendations for a healthy diet. The concept of healthy eating is primarily a problem in rich countries where the lifestyle includes a modicum of outdoor physical activities, high but not always high-quality food consumption, and a trend towards industrially-produced foods instead of locally-sourced, locally-prepared meals.

Oct. 27, 2025 — King’s College London researchers discovered that parts of our DNA once thought to be “junk” can actually help destroy cancer cells. In some blood cancers, damaged genes trigger chaos in these DNA segments, leaving cancer cells vulnerable. ...
Oct. 27, 2025 — People with both cavities and gum disease were found to have an 86% higher stroke risk than those with healthy mouths. The study followed thousands of adults for two decades, linking poor oral health with major cardiovascular events. Regular dental ...
Oct. 27, 2025 — A team of researchers has developed a floral-scented fungus that tricks mosquitoes into approaching and dying. The fungus emits longifolene, a natural scent that irresistibly draws them in. It’s harmless to humans, inexpensive to produce, and ...
Oct. 26, 2025 — Researchers found that life expectancy growth in wealthy nations has dramatically slowed since 1939. Once driven by major reductions in child mortality, longevity gains are now limited by slower progress in older-age survival. The study suggests no ...
Oct. 26, 2025 — GLP-1 drugs, originally developed for diabetes and obesity, may also curb addictive behaviors by acting on reward circuits in the brain. Early trials show reductions in alcohol intake, opioid seeking, and nicotine use. Though more research is ...
Oct. 26, 2025 — Researchers have uncovered microbial evidence in the remains of Napoleon’s soldiers from the 1812 Russian retreat. Genetic analysis revealed pathogens behind paratyphoid and relapsing fever, diseases likely contributing to the army’s massive ...
Oct. 26, 2025 — Researchers found that combining regular exercise with omega-3 supplements can make a big difference for oral health. The duo helps the immune system fight off chronic tooth root infections and reduces bone loss around the teeth. In animal studies, ...
Oct. 25, 2025 — A new study shows that eating more fruits and vegetables during the day can significantly improve sleep that same night. Researchers found a clear link between diet quality and sleep depth, with participants who met the CDC’s daily produce ...
Oct. 25, 2025 — Researchers found that neurons can use fat, not just sugar, to power the brain. When a protein called DDHD2 fails, this process breaks down and leads to serious brain problems. Scientists were able to restore damaged cells by feeding them fatty ...
Oct. 25, 2025 — Inside your body, an intricate communication network constantly monitors breathing, heart rate, digestion, and immune function — a hidden “sixth sense” called interoception. Now, Nobel laureate ...
Oct. 25, 2025 — Scientists at The University of Texas at Austin have developed a revolutionary gene-editing method using bacterial retrons that can correct multiple disease-causing mutations at once. Unlike traditional tools limited to one or two mutations, this ...
Oct. 25, 2025 — Reptiles don’t just pee, they crystallize their waste. Researchers found that snakes and other reptiles form tiny uric acid spheres, a water-saving evolutionary trick. This discovery could illuminate how to prevent gout and kidney stones in ...
