6 foods you thought were vegetarian but aren’t

Or more specifically, Guinness as it uses isinglass in its production. Isinglass is made from the bladders of fish, lovely. There aren't direct traces of isinglass in Guinness, but it is used in the manufacturing process. So remember that next time you want a pint.Hoppily has a great selection of vegan beers, which you can treat yourself to on Amazon.

Parmesan definitely doesn't have any kind of meat substitute in it, right? WRONG. Sorry to all you veggie parmesan lovers but in order for this cheese to be called 'parmesan,' it has to be produced in a traditional method, and that method uses calf rennet. What is calf rennet? I hear you ask – well it's enough to put me off my favourite cheese. It's extracted from the inner mucosa of the fourth stomach chamber of a young, unweaned baby cow. Excuse me while I throw away all traces of parmesan, forever.You don't have to be cheesed off that you can't add any parmesan to your pasta anymore… The Violife Non-Dairy Cheese Alternative Prosociano With Parmesan Flavour is unreal, although it does need a bit of drying first.

Yep, sorry. Ruining your cheese on toast for life. Worcestershire sauce is packed full of anchovies, so unless you're a pescetarian step away from it immediately. You can buy vegan options that apparently takes exactly the same.Bag a vegan alternative to Worcester Sauce so you can sip on a Bloody Mary at brunch.

Guys, marshmallows contain gelatin, didn't you know this? Gelatin is almost as gross as calf rennet, almost. It's derived from collagen inside animals' skin and bones. So no, if you're vegetarian you really, really cannot eat marshmallows when you have a hot chocolate – put that packet down. Oh, and Haribo contains the same thing.Never fear! You can buy some mouth-watering marshmallows from Freedom Confectionery, which are suitable for vegetarians.

Genuinely mind blowing, this one. Figs are not vegetarian. Well kind of. It depends if you count insects as 'animals.' When a wasp pollinates a fig (firstly, did anyone else know wasps had to pollinate figs?), they often gets trapped inside. And for a fig to be edible, they have to have at least one dead female wasp stuck inside. But as the female wasp dies inside, an enzyme from the fruit breaks down the body into protein. Are you sat there in shock because we are. Figs have dead wasp bodies inside them. What is life.

Next time you want to tuck into a massive bowl of creamy yoghurt with berries and honey you healthy thing you, don't. Lots of low-fat yoghurts, especially Muller Light, contain gelatin – there it is again, pops up everywhere doesn't it? Sorry to ruin your yoghurt obsession.If you're looking for a yoghurt that is 100% plant-based, look no further than the Alpro Plain Unsweetened No Sugars. It's an amazing plain yoghurt, which is perfect for mixing with nuts, raisins and fruit.
