I'm no expert, but would suggest that it would cost you NOTHING to watch one or two youtubes of Dr. Chris Knobbe and find out why perhaps you should eliminate polyunsaturated vegetable oils from your diet--especially if they've been heated. as is true in virtually all snack food and virtually all food fried in restaurants, especially fast food. He's not peddling his books or expensive supplements, just presenting longitudinal population studies. If he's correct that AMD was unknown 150 years ago, but has been increasing ever since, then we have to look for what else was unknown 150 years ago and has been increasing ever since to see if there might be a correlation that is actually a causation.
