and frozen vegetables and fruits are so good these days and don't go bad - I am grateful for frozen although I would love to grow my own fresh - some day!
A serving of vegetables is only 1/2 cup. For raw leafy green vegetables, a serving is only 1 cup. https://www.eatforhealth.gov.au/food-essentials/how-much-do-we-need-each-day/serve-sizes
I think that the "5 servings a day" message is discouraging to people, because they think that a "serving" is the same as a "portion". People think that they have to eat huge platefuls of broccoli, and that's just not true.
I can tell you the reason I disliked veggies as a kid.... all of ours came from a can, except on Sundays when we had a roast and we had Green Giant corn and peas... that was okay. Canned veggies, potatoes (thankfully) a meat of some kind and then fruit, also from a can, with cookies.
I never liked the tinned fruit cocktail, either. It was too mushy and too syrupy. We had it only occasionally, as my mom always preferred fresh fruit.I remember having tinned fruit (cocktail salad or peaches) and hated them. Thankfully, we usually only ate fresh fruit picked straight from the orchard.
Seriously, that has never happened to me...When I was growing up (California, 1970s and 1980s), it seems like people didn't know how to cook vegetables in an appetizing way. Everything was too mushy, too bland, or strange/strong tasting. Beans were too sweet, from a can. Broccoli was overcooked. When I started eating at Indian and Asian restaurants, I found out that I liked beans and vegetables.
