      I don’t think that’s the myth, though. I don’t hear people saying that fatty food makes you fat. I do hear “eat less fat.” A high-fat diet is bad for you. Eat too much and it will make you fat among other things but you can say that about anything you over-eat.

      The myth is “low-fat food is automatically healthy.”

      Most people probably don’t need to worry about fat if they just eat a reasonably healthy diet.

      It’s a cognitive problem.

      Good science says: “high-fat diets are associated with these poor health outcomes.”

      People hear: “fat bad! Give us all the fat-free food!”

      Good science says: “no, we need fat just not too much and some kinds are better than others.”

      People hear: “nothing wrong with fat! ‘Fat bad’ was bullshit! Eat all the fat!”

    That salt causes high blood pressure. Like I understand there was a theory about how it could lead to high blood pressure, but empirical evidence shows that modern salt consumption is not the reason for high blood pressure

      It is linked to high blood pressure and people with high blood pressure should limit sodium intake. There’s genetic variation in how sensitive people are to sodium levels but excess sodium will make high blood pressure worse.

      The cause of high blood pressure is more likely to be overall diet and lack of exercise with a bit of genetics sprinkled on top. But excess sodium intake will make it worse.

      It’s a myth that “sodium doesn’t affect blood pressure.” Even if it’s not the cause it can make it worse.
