Japanese researchers found a link between vitamin K2 and prevention of hip fractures and also decreasing the incidence of osteoporosis, and suggested a review of the, "dietary reference value of vitamin K from the perspective of osteoporosis would be useful." The current Japanese reference value is 55mcg for women and 65mcg per day for men. In the US and Canada it is 120mcg per day for men and 90mcg per day for women. In France the limit is 65mcg per day for both men and women.

Bad breath (halitosis) is caused mainly by the breakdown of food particles on the tongue releasing smelly sulfur gases such as hydrogen sulfide. A recent report by biologists at the annual meeting of the American Association for Dental Research in Dallas cites the bacterium Solobacterium moorei as being the organism largely responsible for up to 90% of all cases of persistent bad breath. The bacterium is associated with Periodontitis or severe gum disease.

Lipoprotein (a) is a protein found in the blood that is attached to fat. Researchers at Cambridge University examined data from an Icelandic study that began in 1967 that measured the level of lipoprotein (a) in 2,047 people who later died from heart disease, and 3,921 people who did not die from heart disease. After accounting for factors that are established risk factors for heart disease including old age, high LDL-cholesterol, and high blood pressure, it was found that people with a high level of lipoprotein (a) were 60% more likely to develop heart disease than those with the lowest levels and as the level of lipoprotein (a) increased so did the risk of developing heart disease.

ADHD is one of the most frequently diagnosed childhood psychiatric conditions. While there are many theories regarding the cause of ADHD, we now know that many of the children diagnosed today, have a biological parent who shares the same diagnosis. Other factors that may contribute to the symptoms of ADHD are fetal alcohol syndrome, lead poisoning, meningitis, and a genetic resistance to thyroid hormone.

Researchers at the Department of Medicine, Royal Marsden Hospital in London have just finished a major review of published studies regarding the benefits of Turmeric, also known as Curcumin. Curcumin is a natural polyphenol – a powerful protective ingredient from plants, used in ancient Asian medicine. Since the first article referring to the use of Curcumin to treat human disease was published in The Lancet in 1937, over 2,600 research studies using Curcumin have been published in English language journals.
