“The reported effects are unlikely to be specific to Jarlsberg cheese and may be similar in other hard, long-fermented cheeses,” said Tom Sanders, a professor emeritus of nutrition and dietetics at King’s College London.
Dr. Simon Steenson, a nutrition scientist at the British Nutrition Foundation, said: “Recommending Jarlsberg cheese as a beneficial food for bone health would need to be balanced against existing dietary recommendations.”
More than 2 million women in England and Wales are believed to have osteoporosis, also known as brittle bone disease. It is linked to about 180,000 bone breaks a year.
Experts say bone health depends on adequate consumption of calcium and vitamin D as well as vitamin K, which is also found in dark green vegetables such as kale.
