First, you IBS is probably not tied to these foods. Also, not to be a nit-picker, but corn is a grain, not a vegetable, and zucchini is a fruit, also not a vegetable. The importance of this is in both your IBS and the nutrients you might not be getting by not eating true vegetables. Corn can be a troublesome food for many, as it's a common allergen and also contains a lot of sugar. Carrots are great cooked and raw -- cooked they have more carotenoids, raw more fiber. But here's the thing I found with vegetables -- if you eat organically grown, they tend to use older seeds that were bred for flavor as well as hardiness, whereas conventionally grown produce uses seeds not bred for flavor but only for how well they grow along with pesticides, herbicides, how fast they grow, how you can get every plant to be ready at the same time, and other marketing concerns. Beets, for example, can be bitter if grown conventionally but are quite sweet when grown organically. There are a ton of vegetables out there that many of us thought we didn't like until we tried them grown organically -- collards, kale, beets with tops, parsley, watercress, dandelion greens, red kale (sweeter than green kale), cabbage (wonderful for you when fermented or cultured and with a host of varieties), broccoli, etc. Some of these might bother you but most won't, and cooked they will bother you less than raw, since many really aren't digestible raw even though people are eating them raw a lot lately, such as kale. So go and experiment. As for you IBS, that's a description, not a disease -- it means your tummy hurts. The question still is, why? Allergies? Intolerances (such as to dairy and wheat, very common)? Eating too fast? Going to bed too soon after eating? So many reasons. It might benefit you to see a holistic nutritionist just for another set of eyes, and there are natural plant remedies that can help with this without suppressing your acid that you need to digest protein, as the drugs do. And go buy some vegetarian cookbooks and try out some recipes and see if you can't find some vegetables you like. Personally, I like mine simply steamed, but I only buy organic. Before I discovered organic, I hated them.
I cant afford everything in organic. I can only eat organic apples and many places here i paying over 15 dollars for 3 apples. I was getting an organic produce delivery but i can only afford biweekly but the vegetables mainly the potatoes and yams are so small i get less than 2 meals out of them when i need them to last 2 weeks
You have to buy smart. Most organic vegetables don't cost much more than conventional in the supermarket-- you just have to buy what's in season and what's on sale, just as you would anything else. Don't know what else you spend your money on, but it would seem food would be the most important expense and the others would follow. I'm pretty poor, but I've always been able to buy organic. I just can't buy other things if I do, but that's a good tradeoff if you don't like conventionally grown vegetables. By the way, potatoes are another problematic food, as they turn to sugar quickly and are a simple carb. Do you have a coop near you? You can reduce the price by volunteering. And you're eating sweet potatoes, which are very nutritious, not yams, which don't grow in the US and aren't very nutritious. Have you ever thought about finding someone at a local health food store who can teach you about how to do this better, and how to cook even conventionally grown vegetables in a way you'll enjoy? Good luck.
I've found with my IBS that the most problematic produce is broccoli, cauliflower, onions, celery, and corn. Exacerbated by eating raw. Most other cooked vegetables work for me, especially zucchini despite how boring it is.
