9 Things Plant-Based Cardiologists Have Gone on Record Telling Patients to Stop Buying
A small group of cardiologists has spent the last decade publicly naming the specific grocery items they wish their patients would drop. Here is what they actually say, in their own words.
Most doctors keep their nutrition advice general. A small, visible group of plant-based cardiologists has gone the other direction.
They name specific grocery categories. They tell patients what to leave in the aisle.
The most quoted of them is Dr. Kim Williams, former president of the American College of Cardiology, who told the New York Times in 2014, I recommend a plant-based diet because I know it is going to lower their blood pressure, improve their insulin sensitivity and decrease their cholesterol.
He also, famously, said he does not want to be his patients.
Dr. Joel Kahn, a longtime integrative cardiologist in Michigan, has been equally direct in podcast interviews and in his own writing.
Collecting what these two and a few others have said on the record, nine specific grocery items keep coming up as things to leave in the aisle.
The Nine Items, With the Specific Reasoning Each Doctor Gave
1. Processed Red Meat
Hot dogs, bacon, deli ham, sausages, and the whole category of cured and processed meats sit at the top of nearly every plant-based cardiologist's list.
The World Health Organization classified processed meat as a Group 1 carcinogen in 2015.
Dr. Williams and Dr. Kahn both reference that classification regularly, pointing out that no other category of food in a US grocery store carries that specific designation.
Kahn's instruction is unambiguous.
Skip the butter, the cheese, the salami.
2. Full-Fat Dairy Cheese
Cheese contains more saturated fat per gram than most other items in the dairy case, and dairy cheese is the single largest source of saturated fat in the US diet according to USDA data.
Dr. Williams has made this point in multiple interviews, including a 2016 American College of Cardiology Scientific Session where he said, If people just understood how you could make hypertension just disappear in weeks to months by changing the diet, in a large number of people, they would find it pretty amazing.
Full-fat cheese is a specific target in both Williams and Kahn's writing.
Reduced-fat versions do not solve the issue because the saturated fat profile is still disproportionate to most other foods on the shelf.
3. Butter
Butter is on Kahn's short list by name.
The reasoning is straightforward.
Butter is around 51 percent saturated fat, higher than lard or beef tallow by the same measure.
For patients already managing elevated LDL cholesterol, swapping butter for olive oil in cooking is one of the single most impactful changes.
The 2020 PREDIMED-based evidence showed olive oil swaps producing measurable LDL reductions on the order of 5 to 10 mg/dL in populations with established cardiovascular risk.
4. Sugar-Sweetened Beverages
Soda, sweetened iced tea, flavored lemonade, energy drinks, and sweetened coffee creamers come up again and again in the public statements of plant-based cardiologists.
Dr. Michael Greger, in his written work for the Center for Nutrition Studies, puts sugar-sweetened beverages in the top three dietary drivers of metabolic syndrome.
The specific concern is less the sugar itself and more the liquid form.
The body does not register the caloric load the way it would from solid food, which produces blood sugar spikes that chronic exposure amplifies.
5. Ultra-Processed Vegan Meats as a Daily Staple
This one surprises people.
Multiple plant-based cardiologists have explicitly warned patients against treating products like plant-based burgers, nuggets, and sausages as everyday staples.
Kahn has said on record that these products belong in the occasional category, not the daily one.
The reason is sodium.
A typical plant-based burger patty carries 350 to 450 milligrams of sodium before the bun and condiments.
For patients with hypertension, that single item uses a meaningful share of a recommended daily sodium budget.
6. Refined Vegetable Oils in Large Quantities
Dr. Caldwell Esselstyn, a surgeon and plant-based advocate associated with the Cleveland Clinic's cardiovascular program, has argued for years that patients recovering from cardiovascular events should avoid even plant-derived oils like soybean oil, corn oil, and sunflower oil as cooking staples.
The reasoning is contested within cardiology.
Not all plant-based cardiologists agree with Esselstyn's full oil-free protocol.
What they do largely agree on is that cooking oils used in large quantities contribute significant calories without comparable nutrient density, and that the amount most households use is higher than needed.
7. Store-Bought Baked Goods With Partially Hydrogenated Oils
The US Food and Drug Administration banned the primary dietary source of industrial trans fats in 2018.
The ban was not total. Residual amounts remain legal, and products using the loophole include many commercially baked cookies, crackers, pastries, and microwave popcorn.
Dr. Kahn's advice is to read the ingredient panel, not the front of the box.
The term partially hydrogenated oil is the one to look for.
8. Breakfast Cereals With More Than 8 Grams of Added Sugar
The breakfast cereal aisle is one Dr. Kahn calls out specifically.
The marketing of cereals as healthy, often targeted at families, obscures the sugar content of most mainstream brands.
The practical threshold a few cardiologists cite is eight grams of added sugar per serving.
Above that, the cereal is behaving nutritionally more like a dessert than a breakfast.
Steel-cut oats, rolled oats, and plain shredded wheat are the usual recommended replacements.
9. Processed Snack Chips as Meal Supplements
The last category is practical rather than ideological.
Multiple plant-based cardiologists have noted that patients who successfully reduce red meat and processed meat often replace those calories with processed snacks, especially chips.
Dr. Greger has written about this swap specifically, noting that a bag of potato chips eaten as a lunch substitute contributes almost no fiber, moderate sodium, and a high glycemic load, which undermines many of the gains from the original dietary change.
What They Agree the Replacements Look Like
When the cardiologists on this list are asked what the fuller plate should look like, the answer is remarkably consistent. Dr. Kahn's instruction is as blunt as they get.
Eat beans, eat peas, eat lentils, eat salads, eat whole grains, eat fruits.
For a practical sense of what that looks like on a plate, our guide on hitting 100 grams of vegan protein without struggling walks through the day shape most patients land on when they take this advice seriously.
Dr. Williams has described his own personal diet as plant-based for over a decade, driven initially by his own LDL cholesterol rising to the top end of normal range in his forties.
He has said, publicly, that bringing it back down through dietary change is what shifted his perspective on what he recommends to patients.
One Last Thing
The grocery store does not come with a diet plan.
Watching what a specific group of trained specialists have gone on record saying is a useful shortcut, not because they always agree, but because the overlap is where the evidence sits.
