I always thought vegetables were healthier than fruits.. But more people die from not eating enough fruits than from not eating enough vegetables. According to mainstream thinking at least:

Also true within high-income countries:

Of course "mainstream" medicine isn't "correct". But it's an approximation of correct that we are hard-pressed to best. We know some will be wrong, but we can't easily know which parts. I'm guessing however the fruit/vegetable thing is probably correct. Given we evolved from mostly fruit-eating mammals.
