A Japanese research team bio-imaged vitamin C in mice. A probe chemical emitted red fluorescent light after reacting with vitamin C in the mice's bloodstream. When a dose of exogenous vitamin C was injected, it accumulated in vital organs. This is the first bioimaging of vitamin C in living tissue, showing high sensitivity and good selectivity, paving the way toward the use of this vitamin to treat cancer.

An engineer and an ophthalmologist are developing a portable sensor that can quickly and inexpensively determine whether an eye injury is mild or severe. The device, called OcuCheck, measures levels of vitamin C in the fluids that coat or leak from the eye. The sensor could speed efforts to determine the extent of eye injuries at accident sites or on the battlefield, the researchers said.

Despite previous studies touting its benefit in moderating gout risk, new research reveals that vitamin C, also known ascorbic acid, does not reduce uric acid (urate) levels to a clinically significant degree in patients with established gout. Vitamin C supplementation, alone or in combination with allopurinol, appears to have a weak effect on lowering uric acid levels in gout patients, according to the results of a new study.

High humidity present in bathrooms and kitchens could be degrading the vitamins and health supplements stored in those rooms, even if the lids are on tight, a new study shows. Crystalline substances are prone to a process called deliquescence, in which humidity causes a water-soluble solid to dissolve. Keeping vitamins and supplements away from warm, humid environments can help ensure their effectiveness.

Vitamin C is indispensible for life. We obtain all our vitamin C from out diet and several tightly regulated processes control our vitamin C levels. One protein involved in this is Slc23a1, but its in vivo importance has not been determined. However, researchers have now identified several crucial functions for Slc23a1 in mice: it is involved in absorption of vitamin C by the kidney and in perinatal survival.

Scientists have made a significant discovery about how the vitamin content of some plants can be improved to make vegetarian and vegan diets more complete. Vitamin B12 (cobalamin) is an essential dietary component but vegetarians are more prone to B12 deficiency as plants neither make nor require this nutrient. But now a team, led by Professor Martin Warren, has proved that common garden cress can take up cobalamin.

Researchers have unlocked some of the mysteries of how the developing embryo reacts to fluctuations in the amount of vitamin A present in the maternal blood stream. The developing mammalian embryo is entirely dependent on the maternal circulation for its supply of retinoids, the vitamin A metabolites produced in the body.

Scientists have long suspected the keto diet might be able to calm an overactive immune system and help some people with diseases like multiple sclerosis. Now, they have reason to believe it could be true. Scientists have discovered that the diet makes the gut and its microbes produce two factors that attenuated symptoms of MS in mice.

New research has identified crucial links between dietary choices and the progression of multiple sclerosis (MS). The study explored how enzymes called ceramide synthase 5 and 6 are responsible for the toxic effect of a palm oil-rich diet on neurons in the central nervous system, which causes a subsequent increase in the severity of MS symptoms.

A recent article highlights the critical importance of skeletal muscle mass in the context of medically induced weight loss, particularly with the widespread use of GLP-1 receptor agonists. These medications, celebrated for their effectiveness in treating obesity, have raised concerns regarding the potential for substantial muscle loss as part of the weight loss process.

Planning policies to restrict the number of new fast-food outlets leads to fewer overweight and obese children according to research. Researchers examined the impact of policy in the North East of England where Gateshead Council prevented any existing non-fast-food commercial property from being converted into a hot fast-food takeaway. In sub-group analysis by area level deprivation, they found that those quintiles of deprivation within Gateshead with the highest proportion of fast-food outlets had a statistically significant reduction of 4.80% in the prevalence of childhood overweight and obesity in comparison to comparable neighborhoods in the North East.

Expanding access to new, highly effective weight-loss medications could prevent more than 40,000 deaths a year in the United States, according to a study. The findings highlight the critical need to remove existing barriers that are hindering people's access to effective weight loss treatments and impeding public health efforts to address the national obesity crisis, the researchers said. According to the U.S. Centers for Disease Control and Prevention, about 74% of Americans are considered overweight, with about 43% of those individuals considered obese.

Fatty liver disease is a growing global health concern. Proglucagon-derived peptides (PGDPs), including glucagon, GLP-1, and GLP-2, are known to regulate lipid metabolism in the liver. However, the mechanism underlying this remains unelucidated. Now, researchers have investigated the role of PGDPs, including glucagon, GLP-1, and GLP-2, in fat accumulation in the liver using GCGKO mice deficient in these peptides.

Toddlers in the UK obtain nearly half (47%) of their calories from ultra-processed foods (UPFs), and this rises to 59% by the age of seven, according to a new study. The most common UPFs consumed by the toddlers -- who were 21 months when their parents recorded their diets -- were flavored yogurts and wholegrain breakfast cereals, products typically seen as healthy. By the age of seven, the most common UPFs were sweet cereals, white bread and puddings.
