What is non vegetarian apart from meat,portly and fish?!
Answers: By that I mean their by products. I know some such as geleteain but I don't know them all. I have recenlty truned veggie.
Most cheeses contain rennet. If the ingredients list just states "enzyme" it is almost definitely rennet. Look for cheeses that contain "microbial" or "non-animal" or "vegetable" setting agent instead.
Most packaged candy/lollies/sweets you find in the supermarket seem to contain gelatin these days. Some also contain a glazing agent which turns out to be made from lac insects.
Jelly (called jell-o in the US) is just gelatin, sugar and colouring.
A lot of wines state in the small-print that they were produced with the assistance of fish or milk or egg or seafood products and traces may still remain. Check the label, and always choose wines which, if you take dairy products, only mentions milk, or if you take egg, then only mentions egg.
A wide variety of processed foods (breads, margarines, peanut butter, ice cream, all sorts of other products) contain the emulsifier 471 or E471, which is (unless it actually states that it is soy-derived or vegetable-derived) a by-product of making soap from animal fats.
"Natural colouring" isn't always safe, as it may be cochineal or carmine (both made from insects).
How far do you want to go? I avoid pasta which states that it was manufactured on equipment which is also used to manufacture products containing egg, so "traces may remain". Same with biscuits (cookies and crackers) and some other products.
If you're serious about avoiding those products, it might be prudent to get hold of a book which gives a key to all the numbers in the ingredient labelling system (such as E471, 120, 570, etc.). The one I have is just for Australia and New Zealand, and is about 18 years old, so new additives may have been approved since then, and something which may not be approved here might be permitted in foods in the US or Europe and vice versa.
Avoid processed foods as much as you can, or buy products which you know you can trust.
Well it depends on how vegetarian you want to be. A lot of products contain hidden animal ingredients. Some fancier cheese may have rennet, which is from the stomachs of baby cows. Gelatins are probably a good thing to avoid. Some alcohol has an ingredient derived from fish bladders. Some make-up has animal ingredients (red lipsticks may have carmine, derived from crushed bugs, and glittery make-up might have fish scales to provide sparkles). If you're up for a good read I highly recommend "Skinny B*tch," it's a straightforward guide to what's cool and what's not for vegetarians and vegans.
there are animal by products in all kinds of things, 'hidden' under all kinds of different names. Even many E numbers are derived from animals. For a good, comprehensive list of things you may wish to avoid, I would check somewhere like the Vegetarian Society's website. Also, as it might be helpful for you when doing your research, it is 'poultry', and 'gelatine' (gelatin in the US) you are wanting to avoid, rather than 'portly' and 'geleteain'.
