Researchers at Kyoto University found that a poor, low-yeast diet causes fruit flies' larvae to grow dendrites in an unexpected way. The hyperarborization phenotype is triggered by a simultaneous deficiency in vitamins, metal ions, and cholesterol, which increases the production of Wingless signaling molecules from body wall muscle.
Researchers at Washington State University found that two types of quinoa bred specifically for the Pacific Northwest climate worked well as a high-fiber, high-protein additive flour in commercial cookies. Preliminary results show people preferred sugar cookies with 10% quinoa flour over traditional wheat flour cookies.
A recent poll found that rising food prices have a disproportionate impact on the diets of older adults, especially those in lower-income households and with fair or poor physical or mental health. The study also shows that these groups are more likely to experience food insecurity and eat less healthy diets due to increased food costs.
Two large studies found a link between high consumption of ultra-processed foods and increased risks of cardiovascular disease, bowel cancer, and death. The findings support policies limiting ultra-processed foods and promote eating unprocessed or minimally-processed foods for improved public health.
Researchers discovered that vitamin K acts as an antioxidant, inhibiting ferroptotic cell death and identifying FSP1 as the warfarin-insensitive enzyme responsible. This finding has implications for treating Alzheimer's disease and acute organ injuries.
A study of over 1000 consumers from Australia and NZ found that 27% would pay nearly double the price for 'healthy' drinks with low/no sugar, natural/no additives, or vitamins and minerals. Younger consumers (18-24 years) are more likely to be interested in healthy drinks.
A new study challenges the separation of starchy vegetables from non-starchy counterparts in nutrition research. Starchy vegetables, including white potatoes, were found to meet the definitions for high-quality carbohydrates using five separate indices, with some even scoring closer to fruits and non-starchy vegetables than sweets.
A new study from the University of Georgia found that only about one-third of infants enrolled in WIC meet the daily recommendation for vitamin D by 13 months.

Reputable physicians do not recommend these products due to adulteration with prescription pharmaceuticals and other dangerous chemicals.
New research from North Carolina State University and the University of Copenhagen finds that most bacterioplankton are B1 auxotrophs, meaning they have to glean the vitamin or pieces of it from their environment. The study also reveals fluctuations in genes responsible for making and/or using environmental B1 and precursors over time.

Patients who use vitamin supplements with warfarin are more likely to experience unexplained bleeding and need non-surgical transfusions.
Scientists at Tufts University found that mice born to mothers fed a B vitamin-rich diet had fewer intestinal tumors, while those from deficient diets showed more aggressive tumors. The study suggests epigenetic effects of maternal B vitamin intake may protect against colorectal cancer in offspring.
Women who took daily prenatal vitamins before and during pregnancy were less likely to have children with autism, especially those with high-risk genetic makeups. Folate and B vitamins in prenatal supplements may protect against early fetal brain development deficits.
A study published in Neurology found that nearly 40% of brain tumor patients use alternative therapies, including homeopathic remedies and vitamin supplements. Younger people, women, and those with more education were more likely to use these treatments, which they often sought to add benefits to conventional care.
A new report by The Nutrilite Health Institute found that only about a third of American women meet their fruit and vegetable intake recommendations, leading to potential health issues. Older women have higher total carotenoid intakes compared to younger women after accounting for caloric differences.
A recent study by Stacey Finkelstein and Ayelet Fishbach found that individuals who choose healthy food options feel hungrier if there are no other choices available. The researchers also discovered that this effect is not present when consumers have the freedom to make their own choices.
A new study found that higher folate intake can decrease the risk of hearing loss in men, while antioxidant vitamins have no beneficial effect. Men over 60 with high folate intake had a 20% lower risk of developing hearing loss.
Age-related macular degeneration is projected to increase substantially by 2050, but new therapies may help mitigate its effects. Simulation modeling predicts that combining antioxidant vitamins for prevention and anti-VEGF and laser therapy can reduce the rate of visual impairment and blindness due to AMD from 0.73% to 0.48%.
Pragmatically licensed statements, which sound natural and informative, don't hinder the brain's understanding of negative statements. In contrast, pragmatically unlicensed statements elicit similar ERPs to true words, suggesting negation is not more challenging when useful.
Researchers found that genetic flaws affecting enzyme efficiency can be restored with supplements, offering a personalized approach to health. The study, supported by DARPA, aims to identify variants of enzymes that can be enhanced with vitamin supplementation.
A randomized controlled trial found that treating patients with chronic kidney disease with high doses of folic acid and B vitamins did not lower the rate of death or cardiovascular events. The study suggests that the underlying burden of disease may be too great to produce a measurable benefit from lowering homocysteine levels.
Researchers discovered that plant nectar contains secondary compounds, including nicotine, which repel pollinators and attract 'nectar thieves'. This finding suggests that plants may produce nectar to increase genetic diversity by attracting more visitors despite the potential risk of poisoning insects.
Renowned nutrition expert Dr. Irwin Rosenberg emphasizes the need for more research on vitamins and minerals, highlighting the limitations of current evidence. He advocates for standardized regulations on multivitamin products to ensure customer safety and informed marketing.

A study found that teenagers who take daily multivitamin supplements have healthier diets and lifestyles compared to non-users. Vitamin users were more likely to engage in physical activity, eat a balanced diet, and watch less TV.
A new study by the National Pork Board and the US Department of Agriculture found that six common cuts of pork are 16 percent leaner than 15 years ago, with saturated fat dropping 27 percent. Pork tenderloin is just as lean as skinless chicken breast, containing only 2.98 grams of fat per 3-ounce serving.

A recent pilot study published in the American Journal of Geriatric Psychiatry found that high-dose vitamins can reduce homocysteine levels in individuals with mild to moderate Alzheimer's disease. The multicenter trial, known as Vital, aims to determine if these vitamins can slow the progression of the disease. Researchers are optimis...
Research suggests that high homocysteine levels are related to brain atrophy, with elderly individuals experiencing greater loss of brain cells and volume. Additionally, elevated homocysteine levels have been found to be associated with a higher risk of vascular disease in both healthy and Alzheimer's patients.
