ELI5: For optimum health, doesn't it make more sense for people to eat foods their ancestors ate rather than other types of food that are not based on their origins?

For instance, I'm Swedish and generations of a Swedish diet have formed my physiology. I'm speaking in terms of optimum health, not just sustenance. Would I see an improvement in my health if I returned to the  same nourishment that sustained my ancestors?

Consider that in evolutionary terms your ancestors haven't lived in Sweden long enough, nor had what you think of as that traditional diet, for long enough to have had any significant impact on your genome.  So not really, no.
