"Which of these vegetables to be avoided to control uric acid eggplant, potato, okra, pumpkin ,?"
The vegetables of which you listed, need not be avoided to control uric acid,eggplant, okra, potatoes, and pumpkin, are all fine to eat if you have gout, or uric acid building up. As per the one list, those are foods that can lead to uric acid building up, and a gout flare up occurring. However there are a few vegetables that are on what's called the moderate list for purines. They are asparagus, cauliflower, green peas, kidney beans, lima beans lentils, mushrooms, and spinach. However there are other types of beans/legumes, that can also cause a build up of uric acid. I live with gout, and I've had to learn which foods affects my gout.
