The Conversation I Almost Never Have in the First Session (And Probably Should)

I've been doing this work a long time. Somebody sits down across from me — a mom who hasn't slept right in three years, a fourteen-year-old who says he's "just tired all the time," a couple who love each other and can't stop snapping. We talk about attachment. We talk about the fight they had Tuesday. We talk about what happened when they were nine.

What we almost never talk about in that first hour is what anybody ate that day.

That's a gap, and I want to be honest about it. For most of my career, nutrition sat in a box labeled "somebody else's job." Over the last decade the research has gotten hard enough to ignore that I've changed how I practice. I'm not going to overstate it — I'll get to the limits in a minute, because that part matters as much as the promise. But if you're a parent trying to get your family's health pointed in a better direction, the food on the table and what's in the cabinet is not a side conversation. It's part of the treatment plan.

What the research actually says

Here's the study that moved me.

In 2017, a group of Australian researchers ran what's known as the SMILES trial — a randomized controlled trial of dietary change in adults with moderate to severe major depression. Sixty-seven people. Half got seven sessions with a dietitian working on a modified Mediterranean pattern: whole grains, vegetables, fruit, legumes, nuts, fish, lean protein, less processed food. The other half got an equal amount of warm, structured social contact — real support, just not about food.

At twelve weeks, 32% of the diet group hit remission. In the comparison group, 8% did. The number needed to treat was about four. In plain English: for roughly every four people you help change how they eat, one additional person gets well who otherwise wouldn't have.

That is not a small effect. That's in the range we'd be thrilled about for a lot of interventions we already use.

Then there's the pattern data on kids, which is where I really pay attention as a clinician and as a parent. A 2026 umbrella review pooled seven meta-analyses covering more than 2.5 million children and adolescents and found ultra-processed food consumption tied to short sleep (OR 1.30), insomnia (OR 1.47), poor sleep quality (OR 1.53), and common mental disorders (OR 1.53). Junk food and depression came in at OR 1.62.

Sit with the sleep numbers for a second. In my office, sleep is upstream of almost everything in a kid — mood regulation, attention, irritability, the fuse length on a Tuesday night homework fight. If the after-school snack drawer is quietly costing your twelve-year-old forty-five minutes of sleep a night, you are not having a behavior problem. You're having a biology problem wearing a behavior costume.

On the supplement side specifically, the strongest evidence I've seen is for omega-3s. A 2023 meta-analysis of ten randomized trials covering 1,426 people found a meaningful reduction in depression scores — but only under specific conditions: the formula had to be EPA-dominant (EPA at 60% or more of total EPA+DHA), and the dose had to land between one and two grams a day. Above two grams, the benefit disappeared. Dose and formulation weren't details. They were the whole thing.

Now the part where I stay honest with you

I'm a licensed professional counselor. I am not a physician, I am not a dietitian, and I am not going to sell you a bottle as a cure.

So let me draw the lines clearly.

The umbrella review I just quoted says it out loud: most of those studies are cross-sectional, heterogeneity is high, and causality remains unproven. Depressed people eat differently because they're depressed — that arrow runs both directions and nobody has fully untangled it.

Nutrition is not a substitute for therapy, and it is not a substitute for medication when medication is indicated. Anybody who tells you that you can supplement your way out of major depression, an anxiety disorder, or a trauma history is selling something, and it isn't health.

What I believe the evidence supports is narrower and, I'd argue, more useful: nutrition is a foundation, and most families are trying to build on a cracked one. When somebody is chronically short on the raw materials — omega-3s, vitamin D, B12, iron, magnesium — everything else we do together works less well. Correcting a real deficiency is not a miracle. It's clearing an obstacle that was quietly taxing every other intervention. That's worth doing, and it's usually the cheapest thing on the list.

The part nobody warns you about: the supplement aisle is a mess

Once families decide to take this seriously, most of them do the same thing. They open Amazon, sort by reviews, and buy the one with 40,000 five-star ratings and Prime shipping.

I want you to stop doing that.

In 2025, an independent testing outfit called SuppCo bought 44 best-selling supplements off Amazon and lab-tested them across four rounds — 70 test runs total, in categories like creatine, NAD+, urolithin A, and berberine. Twenty-two failed to meet their label claims, with a twenty-third flagged as a caution. That's over half. And it wasn't a matter of being a little light: 20 of the 22 failures contained between 0% and 3% of the active ingredient printed on the bottle.

Zero to three percent. People paid money, swallowed a capsule every morning for months, and concluded that supplements don't work — when what they actually proved is that that capsule didn't contain anything.

Dietary supplements in the U.S. aren't approved by the FDA before they hit the shelf. There is no gatekeeper checking that what's on the label is in the bottle. Add a marketplace where third-party sellers list into the same product page and counterfeits get mixed into real inventory, and you've got the situation above.

What I tell families to look for instead

Buy from somebody you can hold accountable. That means a company with its name on the manufacturing, a supply chain you can trace, and testing you can actually go read — or a physical retailer with real accountability for what's on the shelf.

Concretely, here's my checklist:

1. Look for third-party verification seals. USP Verified, NSF Certified, NSF Certified for Sport, Informed Choice. These mean an outside lab confirmed identity, potency, and contaminant screening. Not every good product carries one — certification is expensive — but a seal is the fastest signal available to a consumer.

2. Look for published research. Not a testimonial page. Actual studies, with methods, that you can read and criticize.

3. Check EPA:DHA ratio and dose on fish oil. Per the trial data above, EPA-dominant, one to two grams a day. Most drugstore fish oil doesn't come close.

4. Be suspicious of anything promising to treat a diagnosis. That's a legal line, and companies that cross it are telling you something about themselves.

The line I use in session: buy vitamins the way you'd hire a contractor. Not the cheapest bid — the one who'll show you the work.

For what it's worth, I'll tell you what's in my own cabinet, with the caveat that this is my personal experience and not a clinical recommendation for you. I've taken Shaklee supplements for over twenty years. The company was founded in 1956 by Forrest C. Shaklee, it's one of the older nutrition companies in the country, and it publishes clinical research on its products — including the Landmark Study, run in collaboration with a UC Berkeley epidemiologist, which found long-term users had substantially higher vitamin D and B12 levels and better lipid markers than non-users.

I'll be square with you about that study too, because you deserve the same honesty I'd give you in session: it's cross-sectional and company-sponsored, which means it can show a correlation among people who chose to take supplements for years, not prove the supplements caused the difference. Read it with that in mind. What I can speak to personally is twenty years of consistency — the same product, the same standards, no reformulation surprises. That's my experience, not a guarantee for anyone else.

Where a family actually starts

Not with a shopping cart. With an audit.

Three questions to ask at your own kitchen table this week:

• What are we actually eating, at what time, and who's eating alone?

• Where does the sugar and ultra-processed food genuinely enter our week — not where we think it does?

• Is anybody in this house running on a deficiency nobody has ever tested for?

That last one is a lab draw and a conversation with your primary care doctor, and it should come before you buy anything.

If you want help with the rest, we've partnered with a certified nutritionist who works alongside our clinicians. That partnership exists for two reasons: because I want nutrition questions answered by someone actually credentialed to answer them, and because families deserve a plan built around their real life — the sports schedule, the picky eater, the budget — instead of a printout.

You can come in for a full family wellness audit, or just a review of what you're already doing. There's no wrong entry point.

Your family's mental health is built on a lot of things. Some of them we work on in my office. Some of them are already sitting in your kitchen.
