Do you really have to ask ? Everyone knows there is an epidemic of obesity in many countries, with a huge weight of risks for ill health.
It's ironic that malnutrition is another problem which may afflict the obese if their diet is wrong (fad diets are to be avoided), and many others through poverty and illness.
Look no further than the BBC health website ( http://www.bbc.co.uk/health/treatmen...ving/nutrition). The benefits of a balanced diet and regular moderate exercise are surely as well known as the risks of smoking.
The life warranty (life expectancy) in the Philippines is around three score years and ten (70), and a decade longer in the UK. But it comes with no guarantee unless you look after your health. Indeed there is much small print which may invalidate the warranty ! A sensible diet affects not only the brain but every organ in your body. They can't all be replaced !
