I don't think you're deprived of any nutrients. Sticking to a well-chosen, consistent diet is a feature, not a bug. Most of us living in modern cities have a dizzying array of options to the point that today more humans die due to obesity today than to malnutrition.

Heck, even more than 2000 years ago, people were conscious of too much food variety. Here, look at Seneca riffing on it in a letter to his friend (titled 'A beneficial reading program'):

"You must stay with a limited number of writers and be fed by them if you mean to derive anything that will dwell reliably with you [...] 'But I want to read different books at different times,' you say. The person of delicate digestion nibbles at this and that; when the diet is too varied, though, food does not nourish but only upsets the stomach."

It’s not obvious why you think food diversity is related to diabetes risk in the modern age.

Fair question. I did anticipate it, as my argument wasn't watertight.

I mean to say that the sheer variety aggravates our boundless appetites, which are difficult to restrain as-is. Couple that with the unhealthy eating habits our modern age "encourages" (I put it in air quotes because we have personal agency to push back). And we can see where this is going. The details are very much debatable, but the broader point stands.
