Diet studies are horrible for biases as you can search for any confirmation bias you are looking for and find 'paid for' or 'advocacy' research supporting it.
The only way to really sift it is by looking at the aggregate reviews of all the data.
And one thing that is really not in dispute is that overwhelming the Mediterranean Diet, which has small amounts of meat and dairy, and seafood and nuts, olives and veg is the king when it comes to diet.
Year over year over year, in aggregates of hundreds of nutritional professionals it is always at the top.
Yes quantity and quality of meat matters. And seafood meat >> than land meat generally. BUt meat and dairy are part of a healthy diet. The 'healthiest' diet.
And people in regions where the mediterranean diet is the focus live the longest on the planet.
