If you know what you should be doing but can't make it stick — that's exactly what this newsletter is for.

In January 2022, my husband sat across from his doctor after a routine checkup.

He was 31 years old. A student nurse. And his LDL was high.

He knew exactly what those numbers meant.

He sees patients every day living with the consequences of numbers like his — left unchecked for too long.

So when his doctor said, "You have six months to make changes, or we're starting medication," he didn't need it explained to him.

He just hadn't expected to hear it about himself.

A few months later, in May, I stumbled into plant-based nutrition. I'd been reading everything I could find — studies, books, clinical guidelines — and something clicked.

So I did what felt natural. I invited him to try it with me.

I half-expected him to say no. This is a man who loves steak and fried chicken. Loves it. And I wasn't about to pretend otherwise.

But he said yes.

Not because I gave a convincing speech. Because his lab results had already given one.

By his follow-up appointment, his lipid panel had normalized. No medication.

What we changed — and what the research actually supports — is what this newsletter is about.

What the research says (and how confident we should be)

Most "foods that lower cholesterol" articles give you a list and move on. You've probably seen a dozen of them. And they all kind of blur together — eat more oats, try some walnuts, something about flaxseeds.

So I want to do something different.

In 2021, Schoeneck and Iggman published a study in Nutrition, Metabolism and Cardiovascular Diseases that reviewed 108 systematic reviews, 37 dietary guidelines and 20 randomized controlled trials on the relationship between food and LDL cholesterol.

A review of reviews. And what makes this one worth your time is that it didn't just say "this food helps." It graded two things:

  1. How strong is the evidence? (high, moderate, or low quality)

  2. How big is the effect? (small, moderate, or large LDL reduction)

That hierarchy is the value-add. Because knowing that a food might help is very different from knowing how much it helps and how confident the science actually is.

Here's a figure from the study itself showing where each food lands — the bigger the circle, the stronger the evidence. The further down, the greater the LDL-lowering effect.

Foods above the horizontal line — like sugar, solid fats, and unfiltered coffee — are the ones shown to raise LDL.

We're going to cover three things: the foods with the strongest evidence, a counterintuitive finding that might surprise you, and the one principle that matters more than any single food on this list.

The foods with the strongest evidence

These are the foods backed by high-quality evidence for meaningful LDL reduction:

  • Oats, barley, and psyllium — all rich in soluble fiber, which binds to cholesterol in the gut and helps remove it

  • Plant sterols and stanols — naturally occurring compounds that block cholesterol absorption (found in fortified foods, nuts, seeds, and some oils)

  • Oils high in unsaturated fats — canola and rapeseed oil in particular

  • Nuts — almonds, walnuts, and hazelnuts showed consistent effects

  • Soy protein — when it replaces animal protein in the diet

And here's where it gets interesting. When researchers looked at combining these foods — what they call a "dietary portfolio" approach (viscous fiber + plant sterols + soy + nuts) — the combined effect was a 29% reduction in LDL.

That's comparable to a statin.

Not a replacement for one. But comparable in magnitude — from food alone.

The combined approach can reduce LDL by 30–40 mg/dL.

And the key word there is combined. No single food did that. The pattern did.

The counterintuitive finding

Unfiltered coffee — French press, espresso, Turkish coffee — raises LDL.

And this isn't a weak signal. The evidence quality is high.

If you're working on your lipid panel and drinking two or three cups of French press every morning, that's worth knowing.

Filtered coffee (standard drip) doesn't carry the same effect — the paper filter traps the compounds (cafestol and kahweol) responsible for the LDL increase.

I don't drink coffee — for religious and medical reasons — so this one doesn't affect me personally. But I include it because the study includes it, and I'm not here to cherry-pick the findings that are easy to hear.

The supplement question

I know some of you are already thinking it: "So… can I just take a psyllium supplement? Or a plant sterol capsule?"

For isolated LDL reduction — yes, supplements can replicate that specific effect.

But you lose the rest. The phytochemicals. The antioxidants. The fiber that feeds your gut microbiome. The satiety that displaces worse foods from your plate.

Whole foods come packaged in a matrix that a capsule can't replicate.

And the larger pattern matters. Large-scale supplement trials for cardiovascular disease have largely failed to show benefit. Whole food dietary pattern trials have not.

So compared to doing nothing? A supplement is better.

Compared to the actual food? You're leaving a lot on the table.

I put all of this into a deep-dive asset you can save, print, or pull up when planning your meals — with every food graded by evidence quality.
