Ive been reducing UPFs since January. At first it was a lot of label grazing in the supermarket to figure out ingredients, but eventually you find perfect UPF free swaps (eg changing sunpat peanut butter to waitrose own brand 100% peanut butter). Food shopping does become easier eventually.
Breakfasts tend to be porridge (i might chuck in a square of 90% chocolate to jazz it up some days), greek yoghurt with fruit & seeds and nuts, a smoothie, sourdough with scrambled eggs, etc. All quite quick and easy. Now the dc are on their school holidays I'll have a bit more time to in the mornings so might make some sourdough discard waffles/ pancakes, eggy bread etc.
Lunches can be heating up yesterdays dinner, sourdough bread with cheese, soups (plenty of the fresh soup tubs at the supermarket are upf free, just read ingredient labels). In the summer i got quite into picky lunches, so some veg sticks with hummus (again, check the ingredients of the various brands), chunks of feta, kimchi, quiche, omelette, etc.
What do you usually eat for lunch at the moment? Im sure there will be lower or upf free alternatives.
Ive found the 30 different plants a week surprisingly easy, because it also includes herbs and spices - so things like chucking in some cumin seeds, some frozen ginger, or a sprinkle of paprika/ cinnamon/ nutmeg/fresh pepper/ dried herbs all count towards the 30.
