Food groups
The food groups are part of a method of classification for the various foods that humans consume in their everyday lives, based on the nutritional properties of these types of foods and their location in a hierarchy of nutrition. Eating certain amounts and proportions of foods from the different categories is recommended by most guides to healthy eating as one of the most important ways to achieve a healthy lifestyle through diet. Different food guides vary in the number of categories used to divide types of food, but the majority of them include the following classifications: grain products; vegetables; fruits; dairy products; meat and alternatives; fats, oils and sugars.

Nov. 21, 2025 Researchers discovered that the common amino acid arginine can block harmful Aβ aggregation and reduce its toxic effects in Alzheimer’s disease models. In flies and mice, oral arginine lowered plaque levels, reduced inflammation, and improved ...
Nov. 21, 2025 Researchers discovered that chemotherapy can accidentally trigger a stress alarm in immune cells, causing inflammation that damages nerves. Blocking this alarm protected mice from nerve pain and kept their nerves healthier. A drug already being ...
Nov. 21, 2025 A new airflow device from UBC Okanagan engineers traps exhaled aerosols almost immediately, sharply reducing pathogen exposure in indoor spaces. Early simulations suggest it could outperform existing ventilation systems by a wide ...
Nov. 21, 2025 Tiny ingestible spheres filled with engineered bacteria can detect intestinal bleeding by glowing when they encounter heme. Early tests in mice suggest they could become a quick, noninvasive way to monitor gut ...
Nov. 21, 2025 A cutting-edge approach to immunotherapy shows that forcing cancer cells to die through necroptosis can dramatically boost the body's anti-tumor defenses. By combining three existing drugs, scientists reprogrammed malignant B cells so they release ...
Nov. 21, 2025 Researchers found that hot tubs raise core body temperature more effectively than traditional or infrared saunas, leading to stronger boosts in blood flow and immune activity. Only hot-water ...
Nov. 21, 2025 Researchers created a dissolvable microneedle patch that delivers IL-4 directly to damaged heart tissue, jump-starting repair after a heart attack. The targeted approach shifts immune cells into a healing mode while improving communication between ...
Nov. 20, 2025 Researchers uncovered a powerful weakness in lung cancer by shutting down a protein that helps tumors survive stress. When this protein, FSP1, was blocked, lung tumors in mice shrank dramatically, with many cancer cells essentially triggering their ...
Nov. 20, 2025 Researchers have recreated a miniature human bone marrow system that mirrors the real structure found inside our bones. The model includes the full mix of cells and signals needed for blood production and even maintains this process for weeks. It ...
Nov. 20, 2025 A nationwide analysis has uncovered how sprawling fossil fuel infrastructure sits surprisingly close to millions of American homes. The research shows that 46.6 million people live within about a mile of wells, refineries, pipelines, storage sites, ...
Nov. 20, 2025 Researchers discovered a way to keep T cells from wearing out during the fight against cancer, and the approach could make immune-based treatments far more powerful. They found that tumors use a particular molecular signal to weaken T cells, and ...
Nov. 19, 2025 Scientists have developed a new molecule that breaks down beta-amyloid plaques by binding to excess copper in the brain. The treatment restored memory and reduced inflammation in rats, while also proving non-toxic and able to cross the blood–brain ...
