For diabetes in Indian diet, olive oil is good but expensive and not part of traditional cooking. Mustard oil (sarson ka tel) which Indians use traditionally actually has decent properties. Groundnut oil (mungfali ka tel) is fine. Coconut oil is okay in small amounts. Avoid refined vegetable oil and dalda completely. The real deal is portion control - most Indians use too much oil regardless of type. Two teaspoons per meal is reasonable. Better oils won't fix diabetes if you're eating too much fried stuff anyway. Also ghee has some benefits despite being fat-heavy, use it sparingly. The type of oil matters less than how much you use.
