Figure 2 in the paper shows how each of the overall dietary patterns correlates to various measures of healthy aging, and figure 4 in the paper shows how consumption of various components like vegetables or meat correlate to various measures of healthy aging. Most of the correlations were not surprising.
From a Prevention article discussing the study, re: AHEI:
This diet is rich in vegetables, whole grains, nuts, legumes, and healthy fats. It also minimizes red and processed meats, sugar-sweetened beverages, sodium, and refined grains.
The eating plan specifically suggests aiming for five servings of vegetables a day, four servings of fruit, five to six servings of whole grains, and getting a serving a day from nuts, legumes, and vegetable protein.
I’m not sure that the study tells us much that we don’t know.
He has a book coming out. Of all the talking heads, Attia, Huberman, etc, I trust Topol the most. He sticks to evidence, doesn’t make speculative leaps and isn’t dogmatic.
Overall, I liked Attia’s book. But the other day I viewed an interview he posted where he spoke with another doctor, the subject matter which is off-topic to this thread, and thought, after watching the video, “what a crock of poop."
Point being, I believe all these MD “taking heads” have some good ideas, but also some bad ones.
Evidence based ideas are just that, the truth as we know it based on the current mass of evidence. That’s where Topol confines his opinions. Attia unfortunately extrapolates from there and makes claims that aren’t supported by the literature.
