I know there are those that are really hot on a totally plant based diet. I don’t really know to much about that. I do know that a Mediterranean diet has a more powerful effect in terms of reducing overall mortality than a statin in both primary and secondary prevention. In well conducted studies published in major journals.
Not surprising not much effort expended on recommending to pts given very little money to be made doing this and it is a lot more time consuming to prescribe a specific diet vs the 30sec or less to prescribe a statin. The effect of a statin in primary prevention is not particularly strong. You have to treat a lot of people to prevent at death. More than prescribing an anti hypertensive for example. I have prescribed truckloads of statins.
