Although you're young and so far healthy, you could soon be at high risk of heart problems. They are commonly caused by a combination of negative factors including high cholesterol, smoking and being overweight, all of which apply to you. You should see your physician for a formal check-up, known as a cardiovascular risk assessment. Meanwhile, stop smoking. It stimulates the formation of fatty plaque in your arteries, a process called atherosclerosis, or 'furring' that may eventually cause a blockage. Smokers are twice as likely to have a heart attack - they need only smoke a few cigarettes a day to double that risk. Check out the vitamins and nutritional supplements(http://www.mitamins.com/) that can help you quit.

And work out more

Exercise also helps reduce the risk of atherosclerosis. This doesn't mean hours in the gym, just 30 minutes a day of something that gets your heart beating - even a brisk walk to the train station will make a difference. And check out the most effective nutritional supplements(http://www.mitamins.com/) and vitamins that have healthy implications for your blood system in general, and cholesterol in particular.

The dietician says:

You can lower your cholesterol by cutting down on your intake of saturated fat, found in foods like butter and cream. Instead, eat produce containing healthier, monounsaturated fats like olive, groundnut or rapeseed oils. Don't mistakenly strip your diet of eggs, shellfish and red meat - these foods are only likely to raise cholesterol if you fry them in butter or consume them to excess. You need to eat them in moderation as they contain valuable nutrients like protein and B vitamins that give you energy. You need to keep a good balance of vitamins for your health(http://www.mitamins.com/).

And eat well

When you eat out, avoid obvious unhealthy foods like chips or pastry apart from once a week, when you can have whatever you want. Small amounts of alcohol may actually be beneficial, as red wine contains chemicals called flavonoids that help strengthen your arteries - just stay within the recommended limits and have one or two alcohol-free days per week. Flavonoids can also be taken as nutritional supplements. Decide for yourself whether control by eating or by nutritional supplement intake is best for you and your lifestyle.
