Dietary fibre is an important part of a healthy diet. Getting enough fibre has been linked to a lower risk of heart disease, type 2 diabetes, and colon cancer. It also helps keep the digestive system working properly. So, how much fibre do you need each day? Health guidelines recommend that adults consume about 14 grams of fibre for every 1,000 calories eaten. This equals around 25 grams per day for women and 38 grams per day for men. However, most people only consume between 10 and 15 grams daily, which is well below the recommended amount. Fibre Supplements vs...

Nutrients Required to Cope With Hot Weather: Hydration, Electrolyte Balance, and Prevention of Heat-Related Illness IntroductionHot weather places considerable stress on the human body. To maintain a stable internal temperature of approximately 37°C, the body relies on a complex system of thermoregulation that balances heat production and heat loss. During periods of elevated environmental temperatures, particularly when combined with physical activity, the body must work harder to prevent overheating. The primary cooling mechanisms include increased blood flow to the skin and the production of sweat, both of which help dissipate heat. However, these responses also result in substantial losses of...

Emerging research suggests that current vitamin B12 guidelines may not be sufficient to protect the aging brain. A study led by researchers at the University of California, San Francisco (UCSF) found that older adults with lower levels of biologically active vitamin B12—even when their levels fell within the accepted normal range—showed signs of reduced cognitive performance and brain changes associated with neurological decline. Vitamin B12 plays a vital role in producing DNA, red blood cells, and maintaining healthy nerve tissue. However, the study found that “normal” B12 levels do not necessarily indicate optimal brain health. Among 231 healthy adults with...

A large recent study has found that some people with genetic variants linked to the common iron overload condition haemochromatosis experience substantially higher levels of liver, musculoskeletal and brain disease than previously reported, particularly in older age. Haemochromatosis causes iron to build up in the body, potentially damaging joints and organs. The research, led by the University of Exeter and supported by the National Institute for Health and Care Research (NIHR) Exeter Biomedical Research Centre, found higher rates of disease and mortality in men, especially after age 65. Published in BMJ Open, the study analysed data from more than 450,000 participants...
