But on the whole England has much sunnier skies than some other northern European countries. Advice to avoid the sun and protect against skin cancer may also be a factor.
Before health officials in the UK order widespread vitamin D intake how about looking at diet and lifestyle?
Get away from the Internet or TV or video game and get outdoors. Take the dog for an extra walk, walk to the local shops instead of driving, sit and read in the garden or yard at home and go outside during your lunchbreak.
Even on dull days you will benefit from some time spent outdoors especially if it includes a little exercise; that will also benefit and help strengthen your bones.
Fish oils, fatty fish, like tuna, mackerel, and salmon, mushrooms, beef liver, cheese, and egg yolks are all a good supply of vitamin D. Other foods which may be fortified with vitamin D include some dairy products, orange juice, soy milk, and cereals.
Children are in some ways more at risk as their bones grow and strengthen enough vitamin D is a must. But at the other end of the age spectrum the elderly need enough vitamin D to prevent brittle bones which can lead to fractures, damage quality of life and even lead to death. Vitmain D and calcium however go hand in hand in good bone health.
If in doubt take a supplement but make sure that you ask the pharmacist to advise you on the best one for you.
In August 2014 our report "UK malnutrition and rickets health warning" was a shocker. Rickets is associated with the early 20th Century and most people would be surprised to learn it still exists in a rich western country.
"The National Institute for Health and Care Excellence (NICE), which advises the NHS on treatments, has already suggested vitamin D should be given more widely to counter a hidden epidemic of deficiency." "The NICE guidelines called for more free supplements and for supermarkets to sell low-cost tablets."
In general though it seems that education is a must to prevent rickets and brittle bones.
