Disgusting 'natural' ingredients in your food you may have been eating your whole life

We've looked around for some of the most common and least inviting ingredients used in food products today, some of which you've probably been eating your whole life.

Maybe don't read on if you have a weak stomach.

A red dye used in many foods is made from ground up bugs. Carminic acid is extracted from female cochineal bugs to produce carmine, which is shades of crimson and scarlet. In 2012, Starbucks got in trouble for advertising some of its drinks as vegan when they actually contained this bug extract. It is still used in some red and pink products today like jams and cakes, so look out for it on the label. Carminic acid is perfectly safe for most people to consume, but it has been linked with allergic reactions in some.

The poisonous chemical element arsenic is found in water, air, food, and soil, and is sometimes present in many foods including grains, fruits, and vegetables due to absorption through the ground. In 2013, German researchers found traces of it in beer. This is because beer and wine are filtered using diatomaceous earth, which is a natural product that contains iron and metals, including sometimes arsenic. According to the Food Standards Agency, too much arsenic in your diet can be harmful as elevated levels have been linked to an increased risk of some cancers.

Essence from beaver anal glands - are you sure you want to read on? - is responsible for some vanilla, strawberry or raspberry flavours in foods like ice-cream. It's called castoreum and is an FDA-approved natural ingredient, so it's 100% safe for consumption, if a bit gross.

Borax is component of many detergents and anti-fungal products, but it is also used in the food industry. The compound E285 is found in some caviars and in noodle and rice dishes to give them a rubbery texture. It's currently banned in the US and Canada as a food additive but it is allowed in the EU. According to the European Food Safety Authority, E285 is not a major concern to health.

Carrageenan is a polysaccharide extracted from red edible seaweeds, which is commonly found in dairy and meat products. While not too disgusting, it may come as a surprise for those who aren't fond of seaweed. It's used for its gelling, thickening, and stabilising properties. Some limited research has suggested a link between carrageenan consumption and the risk of cancer, but only in animals. According to the USDA National Organic Standards Board, the "scientific evidence does not support claims of widespread negative human health impacts" on people who consume carrageenan in processed foods.

A sheep secretion called lanolin, which comes from sheep's weool, is sometimes listed as a "gum base." It's also sometimes found in Vitamin D supplements. It is of no harm to humans.

Yellow #5, also known as the colourant tartrazine, is a dye that comes from coal tar. It doesn't actually come from coal tar anymore though, and is instead produced as a byproduct of the petroleum industry. Some research suggested that added food colorings (AFCs) were linked with hyperactivity in children. As a result, the ingredients require a warning label in the EU, but there is little regulation for it in the US.

Propylene glycol is an odourless, colourless ingredient found in antifreeze, but it's also found in many foods including breakfast pastries, soft drinks, and cosmetics. While in the EU it has been classified as "not fit for consumption," the US FDA regards it as "generally safe."

A chemical called L-cysteine actually can come from human hair. It's an amino acid used to lengthen the shelf-life of products like bread. Other sources of L-cysteine are chicken feathers, duck feathers, and cow horns. L-cysteine is a natural amino acid and so is perfectly safe to consume, if you don't really mind where it comes from.

Fish bladders contain isinglass, which is a gelatin-like substance added to cask beers and Guinness. It removes residue yeast or solid particles in the drinks, so you should probably be careful about what you order at the bar if you're a vegan. Otherwise it's a safe addition.

Thought cheese was vegetarian? Think again. Many cheeses are made with rennet, which is an enzyme extracted from the inside of a goat's, calf's, or sheep's stomach. It is supposed to give the cheese a better texture, but ambiguous labelling can make it tricky to find a cheese that vegetarians can eat. For everyone else, it's not a problem as rennet is safe for human consumption.
