My father had a heart attack at 43. In response, he dropped red meat and dairy and had to have stents put in 2 years later as his condition deteriorated.

He stopped eating any foods with added oils, as well as anything fatty like nuts and avocados. He eats absolutely zero oil, just basic grains with vegetables and fruits. Ten years later and his doctor says, aside from the stents, he shows no signs of heart disease at all.

Anecdotal improvement aside, your statement about high carbs/low oil being unsustainable is false.

This anecdote is contrary to actual medical advice and does not suffice as evidence against the mountains of research.

You need dietary fats to be healthy, and healthy sources like fish and nuts are often recommended by doctors and dieticians to improve cardiovascular health.

The US also has a very poor handle on heart disease; almost 10% of men in the US have coronary heart disease. The recommended strategies aren’t working.

The recommended strategies aren't being taken by patients.

Diet and exercise recommendations work in the overwhelming majority of people who actually follow them.

This is validated by mountains of research.

The reason we have such poor health outcomes in the US is because people have such terrible diets and sedentary lifestyles which are contrary to those recommendations. And as these lifestyle choices are being adopted in other countries, you see their populations starting to have similarly bad health outcomes of the same kind (e.g., diabetes, hypertension, etc.).

All of this is extremely well-understood.

This guy gets it. It's crazy how corporate interests so thoroughly warped the common man's and even medical professionals understanding.
