Which vitamin is be formed in your body from sunlight?
Answer: Vitamin D
Vitamin D has received a lot of good publicity recently. Studies show that it is linked to boosting immunity, blood pressure regulation and enabling calcium absorption and metabolism. Sunlight is the best way to get adequate amounts – it is manufactured from the action of UVB rays on the cholesterol in our skin. During winter months, when there is lack of sunlight, it is important to get this essential vitamin from the diet. It is available in fortified cow’s milk and soya milk (unfortunately unfortified cow’s milk or soya milk do not contain it), egg yolks, pink salmon, mackerel and sardines. Vitamin supplements are also a good way ay of ensuring sufficient vitamin D supply.

For years it has been recommended to help fight colds and build immunity. Recent studies show that it is also linked to lowering the risk of type 2 diabetes. Vitamin C supplements come in a variety of forms including chewable tablets and water soluble powder.
What is the recommended daily allowance of salt for an average adult?
Answer: 6 g (although the average adult consumes on average 8.6g per day)
Salt has been used for centuries to season and preserve food. Most people however would benefit from reducing their intake to healthy levels. The human body needs sodium chloride, commonly known as salt, as it helps to control the body’s fluid balance and the way muscles and nerves work. The body is generally very efficient in regulating the amount of sodium: if we eat too much salt we become thirsty which encourages us to drink fluids which speed up the excretion of sodium through the kidneys. High salt intake however has been linked to a number of health problems including high blood pressure and osteoporosis. There is now reasonably strong evidence to suggest that people with high blood pressure do benefit from a diet containing less salt, thus reducing the incidence of strokes.
