We are constantly bombarded with conflicting information about healthy food choices, so it's no wonder many of us are confused about what we should be eating.

Hidden sugars and preservatives can often mean so-called 'lighter' foods are laden with hidden calories, sugars and fats.

Mark Killick, Technical Nutritionist at NutriCentre, has pitted some of our favourite dishes, snacks and drinks against each other. Take our quiz to discover whether you're making the right choices at meal times.

WHICH IS HEALTHIER? 

BUTTER OR MARGARINE?

ANSWER: BUTTER

MARK SAYS: Butter is a natural product whereas margarine is manufactured. Butter being full fat fills you up, and is a good dietary source of vitamin A, along with vitamins E, K and D.

Margarine, on the other hand, is made from vegetable oil which is treated with hydrogen gas to make it solid at room temperature. This results in the production of trans fats which are toxic and associated with heart disease.

DARK CHOCOLATE OR CEREAL BAR? 

ANSWER: DARK CHOCOLATE

MARK SAYS: Cereal bars on close inspection are often just biscuits masquerading as health foods. They can be laden with sugar and unhealthy fats which can lead to raised blood triglycerides which are markers for increased risk of heart disease.

Dark chocolate with a high percentage of cocoa (higher than 70 per cent) is a powerful source of antioxidants, which can help protect the integrity of our blood vessels. It is high in magnesium which can help lower blood pressure and improve cognitive function.

WINE OR BEER?

ANSWER: WINE

MARK SAYS: Many people feel that beer drinkers are more prone to putting on weight than wine drinkers, but this really depends on the amount consumed.

Red wine in particular contains polyphenols such as resveratrol which soothes inflammation and because of its antioxidant value has heart protective properties.
