explain how nutrition affects eye health ?
Answers
Maintaining a healthy weight can reduce your risk of developing type 2 diabetes. Diabetes can affect your eyes in a number of ways. Changing levels of blood sugar (glucose) can cause your vision to become temporarily blurry and in the longer term, this can cause you to develop cataracts earlier.
A balanced diet is essential for staying healthy. A diet that is based on starchy foods like rice, potatoes and pasta, with plenty of fruit and vegetables, foods rich in protein such as meat, fish and pulses (for example lentils), some milk and diary and not too much fat, salt or sugar, will give you all the nutrients you need.
Losing weight or maintaining a healthy weight means eating the right foods in the right amounts and exercising regularly. Being overweight in itself does not seem to be a risk factor for any particular eye condition, but being overweight does put you at risk of a number of health problems including:
high blood pressure
type 2 diabetes
heart disease
stroke
some cancers
Some of the health complications of being overweight can cause problems that can affect your sight. These include retinal vessel occlusions, diabetic eye problems and eye conditions related to stroke. You can reduce your risk of developing these conditions, which can lead to sight loss, by maintaining a healthy weight or by losing weight if you need to.
Most people can get all the vitamins and minerals they need from eating a healthy and balanced diet. However, some people may be advised to take a supplement by their GP or eye specialist
