https://nutritionfacts.org/ Is a great resource (and nonprofit) where Dr Greger reviews all the latest scientific studies about nutrition, and then summarizes them in videos. They also post to youtube: https://www.youtube.com/user/NutritionFactsOrg

Spoiler alert: all of the videos can be summed up by: "eat a whole food, plant based diet".

As a general note though - nutrition as a science is _hard_, because everyone responds slightly differently to the same foods in unexpected ways, and it's really hard to do double blind, controlled trials over a long period of time (they cost too much, or are just unfeasible). So I think the best approach is to read/watch a lot of different content from different sources, in order to gain a wide understanding of the current research.
