I have made a determined effort over the last few years to try to mainly eat food that bears a strong resemblance to what it looked like originally and doesn't contain ingredients or additives that I can't pronounce or know what they are.
So my typical week day is a big bowl of greek yoghurt with handful each of mixed seeds, walnuts, flaked almonds, a couple of handfulls of berries (fresh or frozen) with a big squirt of honey across the top. I eat this around midday.
Then about 6ish, some chicken breast (that has marinaded all day in spices and soy sauce or a fish sauce for a salty flavour) I fry that using a bit of butter, this is served with leafy greens, broccoli and whatever other veg has taken my fancy that week.
Snacks - usually a hard boiled egg (if DS hasn't raided my pre-cooked batch in the fridge), handful of nuts, melon or whatever fruit has taken my fancy that week.
I have gone back to butter rather than a spread made of things I can't pronounce.
Weekends are a bit laxer. Yesterday I had a slice of chocolate cake in a cafe with DH, then a Greggs sausage roll and a slice of their pepperoni pizza for lunch, so I had my yoghurt and berries for my dinner. Tonight we will have a roast beef dinner.
I have a large Cadburys Easter Egg awaiting demolition next weekend.
So I do eat "processed crap" and I like it when I do, but I just try to keep the main bulk of my diet as recognisable food.
