I don't think Mini Cheddars are as bad as some snacks, but maybe one packet a day. I looked up Popchips and they are not completely good. Highly processed foods are damaging to the body and brain, and the golden rule is whether you have any of the ingredients in your kitchen.
Ingredients of Popchips are:
Dried Potato, Rice Flour, Sunflower Oil, Potato Starch, Sour Cream & Onion Flavour [Dried Sour Cream (Milk), Dried Onion, Sugar, Yeast Extract, Potassium Chloride, Dried Whey (Milk), Dried Garlic, Maltodextrin, Salt, Natural Flavourings (contain Milk), Acid: Citric Acid, Dried Parsley], Salt
Ingredients of Mini-cheddars are:
Flour (Wheat Flour, Calcium, Iron, Niacin, Thiamin), Vegetable Oils (Palm, Sunflower), Dried Cheese (10%) (Milk) [Dried Powdered Cheese (Milk), Natural Flavouring], Sugar, Glucose Syrup, Salt, Dried Whey (Milk), Barley Malt Extract, Raising Agents (Ammonium Bicarbonate, Sodium Bicarbonate), Acid (Lactic Acid), Natural Flavourings
