Being allergic to mold in food ans well as some spices Nedfleet, you need be careful of mature cheeses meaning anything other than cottage cheese, ricotta cheese and mascarpone. Also be careful of any pre prepared food, including spice mixes, bottled Sauces, canned food, dried and spiced food like soup and sauce powders, savory snax like crisps and crackers, cured and prepared meat products, salami, chorizo sausage, vinegar, balsamic vinegar. And no, the blueberries and youghurt will be okay in the fridge for about a week. But be careful of the berries, they start molding quickly. I would rather keep frozen berries in the deep freeze and take them out for the next morning and cover them with a little sugar called maceration of fruit, to make them more palatable and saucier for the yoghurt.

I have an latex allergy and a mold allergy so it's a lot of food that I can't have and it's hard explaining it to people

Try frozen wild blueberries and thaw a portion each night for the next morning.

Oh yes Ned, and being allergic to mold, is having a food allergy. The sooner we accept we have an allergy if we do like me, the sooner we learn to adjust and the more comfortable it is to do so. Xx
