Transcript of Vitamins : Good For You, Bad For You, or What?

Why take vitamins? Present in low levels in our bodies, but essential to every aspect of our health, vitamins are substances our bodies cannot make.

Therefore, they must be obtained through diet.

While a balanced diet should provide our complete vitamin quota, nutritionists argue that modern life often leaves us depleted.

Intensive agriculture, fast-growth crops and food processing means our food is significantly lower in minerals and vitamins than it used to be.

Meanwhile, high-speed lifestyles leave many people gulping down pre-made meals and grabbing a coffee – not a recipe for nutritional balance.

Drinks like black tea and coffee can reduce mineral absorption while fizzy drinks and sugar contain almost no vitamins.

Chronic stress also depletes vitamin supply. 'Cortisol, the hormone released with stress, uses up B-vitamins and vitamin C and in the long term can burn you out while draining your body of vitamins,' Types of Vitamins Fat-soluble vitamins What are vitamins? Vitamins are essential substances that cannot be manufactured by the body.

We need small amounts of vitamins for growth and development.

Without vitamins the body cannot survive. Vitamin pills versus food To make up the vitamin shortfall, a multivitamin may seem like the obvious answer.

The fact is that the health benefits of vitamin pills are increasingly being brought into question.

While some studies show that vitamin supplementations have a range of benefits from enhanced energy to better fertility, others suggest supplements are harmful.

In 2011, the Iowa Women's Health Study of over 38,000 women found the use of multivitamins was associated with a 2.4 per cent increased risk of death.

Despite being labelled 'natural', over 90 per cent of vitamin supplements on sale are synthetic.

New evidence is emerging that these unnatural forms of vitamin could do more harm than good. What are the best ways of getting vitamins? Getting the balance right You are what you eat!

5 servings of different fruits & vegetables daily will ensure you get plenty of vitamins & minerals

Foods lose vitamins & minerals when they are cooked : steam, poach, grilling & baking are better than frying

Choose fresh foods over processed and eat as soon as possible

Supplements can be helpful and health-enhancing or harmful and a waste of money. Good For You, Bad For You, or What? Vitamins (A, D, E and K) are usually found in meat and meat products, animal fat and vegetable oils, dairy products and fish.

They are transported around the body in fat, and your body stores any excess in the liver and fatty tissues.

This means you don't need to get them from food sources every day. Water-soluble vitamins (B, C, folic acid) are found in meat, fish, fruit, vegetables and wholegrains.

They are transported around the body in water.

This means your body can't store them because you pass the excess through urine.

You need to eat foods containing these vitamins every day.

Water-soluble vitamins can be destroyed by cooking – so steam and grill rather than boil.
