                        answer: 1, 
                        explanation: "The correct answer is 3.5oz (100g) of cheddar cheese, which contains an estimated 739mg of calcium. All the other foods in the list are good sources of calcium, but they don't come near the daily amount. Other foods very high in calcium are certain fish, including whitebait and sardines."

                        answer: 4, 
                        explanation: "The correct answer is vitamin D. Vitamin D is needed by the body to absorb calcium, which helps maintain healthy bones. However, most people don't get enough from food or the sun. This is especially true if you live in a region that is nearer the North or South Pole than the equator (for example the UK, Canada or southern Argentina), where the sunlight to make vitamin D is only strong enough during the summer. If you're aged 65 years or over, if you completely cover yourself for religious reasons, for example by wearing a burka, or you never go outside into the sunlight you're more likely to be deficient in vitamin D."

                        answer: 3,

                        answer: 4, 
                        explanation: "The correct answer is that a 'use by' date is given for foods that could be dangerous if you eat them after expiry and that a 'best before' date just shows that it might not taste as good. Foods, such as meat and fish can cause food poisoning if they aren't eaten within a certain time limit, even if they look and taste fine. These foods are marked with a 'use by' date. Other foods, such as coffee granules and biscuits have a 'best before' date because they may not look or taste as good after the expiry date."

                        answer: 3, 
                        explanation: "The correct answer is oily fish. Oily fish, including salmon, mackerel and sardines are rich in a special type of fat known as omega 3 fatty acids. A good intake of omega 3 fatty acids has been shown to substantially reduce a person's risk of a fatal heart attack. The UK Government recommends eating one to two portions of oily fish every week."

                        explanation: "The correct answer is 33%. We should get our main source of energy from starchy foods. Of course, some carbohydrate foods are better than others - wholegrain rice, bread and pasta are the healthier choices, whereas sugary foods should be kept to an occasional treat."

                        answer: 3, 
                        explanation: "The correct answer is that men consume an average 11g of salt and women an average of 8g. Even if you don't add sprinkle salt over your dinner, eating more than the recommended daily allowance is alarmingly easy - 75% of the salt we consume is already in the foods we eat, such as ready-made soups, breads and ready meals. High salt intake is linked to high blood pressure, so it makes sense to cut down."
