What if the food you were told was “heart healthy” is not doing much for your LDL?
What if “eat more fiber” is too vague to be useful?
And what if oatmeal really is helpful—but only because of a specific type of fiber, while other “healthy” grains may not have the same effect?
That is what caught my attention in an interview with Dr. David Jenkins, the researcher behind the Portfolio Diet. His approach is not based on one magic food. It is more like building an investment portfolio: combine several foods that each lower LDL in different ways, and the results can add up.

Lower Cholesterol With Food: The Portfolio Diet Explained | Dr. David Jenkins
This is not a claim that everyone must eat exactly the way we do. It is our take on the foods that helped us—and the foods we actually enjoy enough to keep eating.
For us, that means:
- Barley in soups
- Beans every day
- Apples in salads
- Oats and other high-fiber foods
- Nuts
- Soy foods
- More vegetables and fruit
- Extra-virgin olive oil instead of saturated fats
- Fewer fatty meats, butter, and large amounts of cheese
We also made some decisions that may not match the standard Portfolio Diet. I do not like plant sterols. They feel too artificial to me, so I would rather get my cholesterol-lowering foods from ordinary meals.
That is the larger lesson:
The best cholesterol-lowering diet is not the one that looks perfect on paper. It is the one you can enjoy and repeat.
The Portfolio Diet: A Food Strategy, Not a Miracle Food
Dr. Jenkins developed the Portfolio Diet by combining several dietary tools known to help reduce LDL cholesterol:
- Viscous soluble fiber from oats and barley
- Plant proteins, especially soy
- Beans and other plant foods
- Nuts
- Plant sterols
- Replacing saturated fat with unsaturated fat
The idea is simple: each part may help a little, but together they can make a much bigger difference.
That is very different from searching for one magical ingredient.
A bowl of oatmeal will not erase an otherwise high-saturated-fat diet. A handful of almonds will not compensate for every other meal. But adding several helpful foods while reducing the foods that push LDL upward can create a meaningful change.
That approach helped me lower my LDL from 135 to 80 in 2024.
It was not instant, and it was not perfect. I still occasionally ate Costco hot dogs with my daughter and had pizza with my family. Those foods simply stopped being everyday staples.
1. Oats: The Breakfast Food With a Specific Job
Oatmeal is often recommended for cholesterol, but the reason matters.
Oats contain beta-glucan, a viscous soluble fiber. When cooked, it becomes sticky and thick. That texture is not just a culinary detail—it is part of what makes the fiber useful.
According to Dr. Jenkins, viscous fiber can trap bile acids in the digestive tract and reduce their reabsorption. Because bile acids are made from cholesterol, the body has to use more cholesterol to replace what was lost.
That can help lower LDL.
Good options include:
- Oatmeal
- Overnight oats
- Oat bran
- Oats blended into smoothies
- Oats mixed with fruit and nuts
- Oats used in homemade baked goods
But here is the contrarian part: not every food labeled “whole grain” necessarily has the same cholesterol-lowering effect.
“Fiber” is not one single substance. Different fibers behave differently. Oats and barley are especially useful for LDL because of their viscous beta-glucan.
2. Barley: The Food I Actually Look Forward To
Oats may get the publicity, but barley is one of our favorites.
I love barley in soups. It makes them hearty, chewy, and satisfying without needing much meat, cream, or cheese.
Barley works well in:
- Vegetable soup
- Bean soup
- Lentil soup
- Grain bowls
- Salads
- Pilafs
- Stuffed vegetables
Like oats, barley contains viscous beta-glucan.
Dr. Jenkins emphasized that different whole grains contain different types of fiber, protein, and minerals. So it is not enough to lump every grain into one category and assume they all have identical effects.
If the goal is specifically lowering LDL, oats and barley deserve special attention.
3. Beans: Our Everyday Cholesterol Tool
We love beans, and we eat them every day.
That may sound repetitive, but beans are incredibly flexible:
- Black beans in tacos
- Chickpeas in salads
- Lentils in soup
- White beans with vegetables
- Kidney beans in chili
- Hummus as a spread
- Beans in grain bowls
- Lentils mixed into tomato sauce
Beans bring several benefits at once:
- Soluble fiber
- Plant protein
- Resistant starch
- Potassium
- Fullness
- A practical replacement for meat
That last point is important.
Beans may help because of what they contain, but also because of what they replace. If beans take the place of sausage, bacon, fatty beef, or a cheese-heavy meal, you are not merely adding fiber—you are also reducing saturated fat and dietary cholesterol.
Nutrition is rarely an either-or situation.
It is not necessarily “beans work because of fiber” versus “beans work because they replace meat.”
They can work for both reasons.
4. Soy: It Helps Coming In and Keeps Something Else Out
Soy foods include:
- Tofu
- Tempeh
- Edamame
- Soy milk
- Soy yogurt
- Soy-based meat alternatives
Dr. Jenkins made an important point about soy: its benefits may come from both its own nutritional properties and the foods it replaces.
Soy provides plant protein, and its amino-acid profile may help improve LDL. But tofu replacing a fatty cut of meat also means less saturated fat and dietary cholesterol in the meal.
That is why “Does soy help by itself, or only because it replaces meat?” is probably the wrong question.
The answer may be both.
Dr. Jenkins mentioned eating tofu with tomato sauce for breakfast before the interview. I am a big fan of tomato sauce too. It can make tofu, beans, vegetables, and whole grains much more appealing.
I am not putting it on oatmeal—but almost everything else is fair game.
5. Nuts: High-Fat Does Not Automatically Mean Bad for LDL
Nuts are full of calories and fat. That fact has caused a lot of confusion.
The more useful question is: What kind of fat, and what comes with it?
Nuts generally contain mostly unsaturated fat along with:
- Fiber
- Plant protein
- Minerals
- Polyphenols
- Other beneficial plant compounds
They can be added to:
- Oatmeal
- Salads
- Yogurt
- Grain bowls
- Stir-fries
- Fruit
- Smoothies
I love apples in salads, especially with nuts and beans. The apple adds sweetness and crunch, while the beans and nuts make the salad more satisfying.
A small handful of nuts can be enough because they are calorie-dense. But their fat and calorie content does not make them equivalent to butter, lard, or fatty meat.
The whole food matters—not just the number of calories or grams of fat on the label.
6. Plant Sterols: Backed by Research, but Not Our Favorite
Plant sterols are included in the traditional Portfolio Diet because they can reduce the absorption of cholesterol in the intestine.
They are found naturally in small amounts in plants and are also added to certain fortified products.
They may work. But personally, I do not like relying on them.
They feel too artificial to me, especially when they appear in specially fortified spreads or processed foods. I would rather focus on foods I already enjoy:
- Oats
- Barley
- Beans
- Lentils
- Fruit
- Vegetables
- Nuts
- Soy
- Extra-virgin olive oil
This is an important distinction:
A food can be scientifically legitimate and still not be the right choice for your personal eating pattern.
If someone wants to use plant-sterol-fortified foods, that is a decision to discuss with a healthcare professional. But we do not consider them necessary for a successful Portfolio-style approach.
7. Extra-Virgin Olive Oil: Better Than Butter, Not a Free Pass
Extra-virgin olive oil is mostly unsaturated fat and can be a useful replacement for butter, lard, shortening, beef tallow, and other fats high in saturated fat.
Dr. Jenkins also pointed out that less-processed oils may retain polyphenols and other compounds that are lost during processing.
The PREDIMED trial found cardiovascular benefits associated with Mediterranean-style eating patterns supplemented with extra-virgin olive oil or nuts.
That does not mean olive oil should be poured over everything without limits. It is still calorie-dense.
The practical takeaway is:
- Use olive oil instead of butter when possible
- Choose extra-virgin olive oil for dressings and low-to-moderate-heat cooking
- Keep portions reasonable
- Remember that replacing saturated fat is the important part
Also, “plant-based” does not automatically mean “low in saturated fat.”
Coconut oil and coconut-milk products can be high in saturated fat. Vegan desserts can contain plenty of saturated fat if they are made with coconut fat.
Plant-derived is not the same thing as cholesterol-lowering.
The Overlooked Bonus: Potassium
One of the most important points from the interview was easy to miss: many of these LDL-lowering foods also provide more potassium.
Beans, lentils, fruits, vegetables, whole grains, and nuts can all contribute potassium to the diet.
That matters because potassium can support healthier blood pressure. So the same eating pattern may help address two major cardiovascular risk factors:
- Lower LDL cholesterol
- Lower blood pressure
Dr. Jenkins connected this with a DASH-style approach: more potassium-rich plant foods, along with less saturated fat and more viscous fiber.
The benefit is not just one nutrient. A bowl of bean and barley soup may provide:
- Viscous and other fibers
- Plant protein
- Potassium
- Minerals
- Polyphenols
- Fullness
- Less saturated fat than a meat- or cream-based alternative
People with kidney disease or other conditions affecting potassium should get individualized medical advice.
What About Cholesterol in Food?
Dr. Jenkins explained that humans do not need to eat dietary cholesterol to be healthy.
The body can produce the cholesterol it needs.
A diet made entirely from plant foods contains no dietary cholesterol, yet it can provide fat, protein, carbohydrates, vitamins, minerals, fiber, and calories.
That does not mean everyone must eliminate every animal food. It does mean dietary cholesterol is not an essential nutrient, and reducing animal foods can be one way to reduce saturated fat and dietary cholesterol at the same time.
Diet and Statins Do Not Have to Be Enemies
The interview also made clear that diet and medication are not necessarily competing strategies.
Researchers are studying what happens when cholesterol-lowering foods are combined with medications such as statins. Diet may improve LDL and other risk factors, while medication may provide additional reduction when appropriate.
Dr. Jenkins also discussed newer medications, including oral PCSK9 inhibitors and bempedoic acid.
Bempedoic acid works earlier in the liver’s cholesterol-production pathway and does not cause the same muscle-related symptoms associated with statins, although it still has its own potential risks and is not right for everyone.
The right treatment depends on the individual, including:
- LDL level
- Personal history of cardiovascular disease
- Diabetes
- Blood pressure
- Smoking
- Family history
- Genetic cholesterol disorders
- Kidney function
- Overall cardiovascular risk
Changing your diet does not mean you should stop prescribed medication without medical guidance.
Our Practical Version of the Portfolio Diet
Here is what worked for us:
- Eat beans every day.
- Use barley regularly, especially in soups.
- Eat oats often, particularly at breakfast.
- Add apples and other fruit to salads and meals.
- Include nuts in sensible portions.
- Use tofu, tempeh, or edamame when convenient.
- Replace some meat with beans, lentils, or soy.
- Use extra-virgin olive oil instead of butter or animal fats.
- Reduce foods high in saturated fat.
- Get more potassium from beans, fruits, vegetables, whole grains, and nuts.
- Do not obsess over perfection.
- Skip plant sterols if they do not fit your preferences.
The biggest change was not finding one superfood.
It was building meals around foods that could do several jobs at once.
The Real Secret Is Repetition
Dr. Jenkins made another point that deserves more attention: diet is harder than taking a pill.
You have to shop for it, prepare it, cook it, and decide to eat it again tomorrow.
That is why taste and convenience matter.
I do not want a theoretical diet that looks impressive in a research paper but makes me miserable in my kitchen. I want food I genuinely like:
- Barley in soup
- Beans every day
- Apples in salads
- Oatmeal
- Nuts
- Tomato sauce
- Tofu
- Vegetables
- Fruit
The Portfolio Diet worked for us because it became ordinary.
And ordinary is exactly what you want a long-term health habit to become.
