I tried looking up on this topic but there seems to be opposing advice given

Some say eating a high fat-high protein diet did wonders for the erection quality. Whereas the opposing camp says removing all red meat, lowering fats did wonders for their erection quality.

And the same extremely opposing advice also carries over to carbs. Some say increasing more carbs did wonders, whereas some say removing the carbs helped decrease the blood glucose and gave better erections.

So honestly I don't know which camp to listen to. If someone has looked into this subject matter and did some research, could you please help a brother out? Especially if you've personally had any degree of ED that you fixed through diet or lifestyle changes, I would love to hear you out and what worked for you
