Maybe, but insulin is an absolutely necessary hormone that we cannot live without.
The point is in the measure, not to much, not too little. Like all in life.

You didn’t say anything relevant.
I think I did. If you eat too much refined sugar, it would increase insulin levels beyond what is admissible. If you consume sugar in its proper quantities, insulin levels would be normal and non-problematic.
People's cells become resistant to insulin and that disease is not caused by sugar intake alone. Other common toxins over time, particularly machine oils such as canola and soybean oil, which are ubiquitous in bread and processed food, are a much bigger factor in causing insulin resistance and other health problems.
Nothing you say is credible because you’re a vegan. In any domain. No propaganda resistance. Muted.
