TEST YOUR KNOWLEDGE ON VITAMINS AND NUTRITION

Which vitamin is be formed in your body from sunlight?
Vitamin A
Vitamin B1
Vitamin C
Vitamin D

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.

A good source of Vitamin C is ...
Beef
Dairy products
Fruit
Nuts.

Answer: Fruit
Vitamin C is contained in fruits and vegetables. Good sources include oranges, kiwis, peppers, broccoli sprouts and sweet potatoes. 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?
0.6g
3g
6g
10g

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.

Which vitamin is particularly good at keeping stress under control?
Vitamin B5
Vitamin A
Vitamin K
Vitamin B1

Answer: Vitamin B5 (Pantothenic acid)
In truth the family of B vitamins work together to help control stress in the body but Vitamin B 5 is especially known as the “anti-stress vitamin”. It plays a major role in the production of adrenal hormones which work together to keep the body calm and in balance. Vitamin B5 is present in foods such as beef, kidney, eggs, fresh vegetables and wholegrains.
