VITAMIN D AND OSTEOPORISIS

An Australian government report in 2005 highlighted calcium and vitamin D deficiency in the diets of many Australians, leading to osteoporosis.

People over 50, those with dark skin, some migrant groups and those who are covered for cultural reasons, have a reduced ability to produce and store vitamin D from exposure to sunlight.12

Oily fish like salmon can be a good source of Vitamin D and calcium (especially if you consume the edible bones).

Omega 3 Consumption and Natural Sun Protection
Recent research reports suggest that eating just one gram of omega 3 fatty acids daily significantly improved the tolerance of its study group to UVB radiation after just one month. The effect disappeared rapidly once omega 3 consumption stopped.13
