Do You Know If These Food "Facts" Are True Or False?

A stick of celery has about 10 calories, but it only takes 2 calories to digest it, [according to Dr Tim Garvey](http://www.bbc.co.uk/news/magazine-21723312), chair of the Department of Nutrition Sciences at the University of Alabama.

Kale has [150mg calcium per 100g](http://ndb.nal.usda.gov/ndb/foods/show/2983?count=&fgcd=&format=&lfacet=&manu=&max=35&offset=&qlookup=11233&sort=), whereas whole milk [has 113mg](http://ndb.nal.usda.gov/ndb/foods/show/180?count=&fgcd=Dairy+and+Egg+Products&format=&lfacet=&manu=&max=35&offset=&qlookup=whole+milk&sort=).

It never burns off _entirely_, although most of it will in recipes that require a long enough cooking time. A [study](http://www.ncbi.nlm.nih.gov/pubmed/1556354) published in 1992 tested six recipes and found that they retained between 4 and 85% of the alcohol content after cooking.

There are actually a ton! Unlike most proteins derived from animals, not _all_ plant-derived proteins are "complete". But plenty are, including [cauliflower](http://nutritiondata.self.com/facts/vegetables-and-vegetable-products/2390/2), [black beans](http://nutritiondata.self.com/facts/legumes-and-legume-products/4284/2), and [quinoa](http://nutritiondata.self.com/facts/cereal-grains-and-pasta/10352/2).

Some components in the chewing gum will break down in your digestive system. What doesn't will just pass through you [undisturbed](http://www.scientificamerican.com/article/fact-or-fiction-chewing-gum-takes-seven-years-to-digest/).

It's true! According to [the NHS](http://www.nhs.uk/Conditions/Osteoporosis/Pages/Prevention.aspx), 10 minutes of exposure to sunlight twice a day in the summer should give you enough vitamin D to last the year. So go forth and bask.

Cherries, strawberries, and peaches [do too](http://www.bbc.co.uk/nature/life/Rosaceae).

They [grow underground](https://www.foodallergy.org/allergens/peanut-allergy)!

The food colouring known as cochineal, carmine, carminic acid, natural red 4, and E120, is made from an extract from [squished scales of the female cochineal bug](http://www.wired.com/2015/09/cochineal-bug-feature/).

Bananas are rich in potassium, and [0.012%](http://www.ccnr.org/About_Radioactive_Bananas.pdf) of naturally occurring potassium is radioactive, making bananas slightly radioactive. It's not just bananas, though – all foods rich in potassium are slightly radioactive. In fact, humans contain naturally occurring potassium, making us slightly radioactive too.
