A U.K. study of more than 12,000 patients who previously suffered a heart attack showed that daily intake of folic acid and vitamin B12 supplements for almost seven years didn't lower the risk of stroke, cardiac death and heart attack but did result in a 28% reduction in homocysteine levels. Researchers said the findings highlight the importance of focusing on proven drug therapies and lifestyle changes.
A small U.S. study of diabetic children found 59% had insufficient levels of vitamin D, while 23% were considered deficient. Researchers said current American Academy of Pediatrics guidelines of 400 IU of vitamin D daily for children may not be enough and suggested 1,000 IU daily may be needed during winter months.
Restaurant chef Wayne Roe puts his 30 years of experience to use helping young hospital patients regain appetites lost to treatments and medication.
