People in England do not know what their diet contains and are surprised at the level of "hidden nasties" in their favourite foods, a survey has revealed.
Two thousand adults took part in the Food IQ quiz with over three quarters (77%) of them scoring 50% and under.
The survey, backed by the Department of Health's Change4Life campaign, showed that people still do not realise how much salt, sugar and saturated fats are contained in the food they eat every day.
Just three people - less than 1% of those surveyed - correctly answered all 12 questions, while one in 10 (11%) people could only answer four questions correctly.
50 Healthiest Foods
Almonds(01 of50)
Open Image ModalApples(02 of50)
Open Image ModalApples are an "excellent source of pectin, a soluble fiber that can lower blood cholesterol," says Wixom. The fruit is also high in fiber and its peel contains something called ursolic acid, which has been shown in recent studies to lower the incidence of obesity. "Apples also contain quercetin, which has anti-inflammatory properties and can help in preventing respiratory problems," Heather Bauer tells The Huffington Post. "Research shows that pregnant women who incorporated apples into their daily diet were less likely to give birth to a child with asthma." (credit:shutterstock)

Open Image Modal"The dark red color indicates the powerful phytonutrient package of beets," Diekman tells The Huffington Post. Indeed beets are rich in betalains, such as betanin and vulgaxanthin, that give them their pigment and also have anti-inflammation and antioxidant properties.Beyond that, beets contain significant amounts of folate, vitamin C, B6, iron, phosphorous, calcium, magnesium, zinc, niacin, riboflavin and thiamine.

Open Image ModalBlackberries And Raspberries(08 of50)
Open Image ModalBerries are low in calories and are excellent sources of fiber, vitamin C, antioxidants and phytochemicals, and, according to Wixom, some research suggests they help with such divergent health challenges as age-related mental decline, heart disease, some cancers and urinary tract infections. On the mental acuity front, the berries are full of anthocyanins for boosting memory, according to Joy Bauer, but that's not their only age-related benefit. "These foods are high in antioxidants, protect the body from the harmful effects of by-products known as free radicals, made normally when the body changes oxygen and food into energy," according to experts at the Penn Institute on Aging at the University of Pennsylvania.

Open Image ModalBlueberries(10 of50)
Open Image ModalWhile all berries provide healthful antioxidants, vitamins, fiber and phytochemicals, studies show that blueberries have a particular and unique health benefit. "Among the fruits with the highest level of antioxidants, blueberries have been linked to lowering cholesterol, reducing diabetes risk, slowing the aging process, improving motor skills and supporting urinary and vision health," says Fitzgerald. "The compound, anthocynanin, gives blueberries their color and may be the main component of its antioxidant and anti-inflammatory properties." (credit:Alamy)

Open Image ModalThe majority of people (85%) do not realise that a pre-packed ham and cheese sandwich has more salt than a chicken tikka masala ready meal or a packet of ready salted crisps.
Six in 10 (63%) people do not realise that a small pepperoni pizza has more saturated fat than fish and chips, and 60% of people do not know that the daily maximum amount of salt recommended is only one teaspoon.
The low scores come despite the fact that most people (84%) surveyed say they would like to be healthier.
The research goes on to show that factors such as cost and time are additional barriers when it comes to choosing the healthiest options.
Seven in 10 (69%) people prioritise price when shopping for food, one in five (21%) choose items that are easiest to prepare, and more than half (51%) choose items they are sure the whole family will eat.
Ainsley Harriott, Change4Life campaign ambassador, said: "It's really important to be aware of what hidden nasties may be in your food, and to know what you're putting in your or your family's bodies.
"Some of our favourite meals, takeaways and snacks contain high amounts of salt, sugar and saturated fat - it's our job to make sure that we know where they are hiding.
"But it is possible to eat well on a budget, and you don't have to give up your family favourites or treats just to be food smart.
"There are simple changes you can make which will help: try to prepare food at home, cut down on saturated fat, swap high sugar options for lower ones, watch out for hidden salt in foods and check the label on the food you buy."
