In India we use sesame seed oil for both external as well as internal. We have been doing that for generations and haven't thought of it creating any health issues. Maybe too much can create health issues.
In some parts of India they consume groundnut oil (peanut oil) for cooking. But they usually say that we have to do enough physical activity to break down the oil. But mostly in villages, people work in fields and they easily do a lot of physical activity to break down the consumed oil.
But I think that only too much creates health issues and otherwise it is fine.
That is interesting to know. I am not sure if seed oils are solely to blame for our modern health issues, but hope my experiment will bring some benefits.
According to some of the seed oil guru's, even if you were not so active in the past, the weight gain was less proficient as you didn't eat seed oils. However maybe they didn't consider in India where it was consumed much longer so the argument could be flawed.
Is Ayurvedic medicine very common in India too?
Yes, Ayurvedic medicines are popular in India as Ayurveda originated only in India.
