A patient once told me she’d rather die than describe her p**p to a doctor.

She was only half joking.

I get it. There’s no polite way to bring it up.

But here’s the thing: what’s in the toilet bowl is one of the most honest health reports your body gives you, and most people go their whole lives never reading it.

So let’s just talk about it.

Bright red blood on the paper? Usually a hemorrhoid or fissure. Nothing to panic about once.

But if it keeps coming back, shows up with no clear cause, or comes with weight loss, fatigue, or a change in your bathroom habits, that’s the pattern I’m trained to take seriously.

It’s also the pattern I see most often in early colore**al cancer.

Black, tarry stool is a different story. That’s older blood, usually from higher up, and it means see someone now, not next week.

Even color changes matter. Pale or clay-colored can point to your bile duct. Yellow and greasy can mean your body isn’t absorbing fat the way it should.

Here’s my actual rule of thumb: a one-off weird bathroom trip after a big meal, ignore it.

If a pattern lasts more than two weeks, especially with pain, fever, or weight loss you can’t explain, get it checked.

You don’t need the perfect words. “Something’s been off” is enough to start.

Week 4: Blanching.

Everyone’s asked some version of the same question this month: what if I don’t want my vegetables hot?

Blanching is the answer. A quick dunk in boiling water — 30 seconds to 2 minutes, depending on the vegetable — kills what raw exposure can’t, then straight into ice water to stop the cooking and lock in color, crunch, and nutrients.

You end up with a vegetable that’s technically cooked, but tastes and feels raw. Perfect for salads, grain bowls, or anything you want cold and crisp — without skipping the step that actually protects you.

Four weeks. Four techniques. One goal: vegetables that are both safer and better.

Stay tuned for a BONUS method next week!

Week 3: Steaming.

If sautéing and roasting are about flavor with a side of protection, steaming is the opposite: almost no flavor added, maximum nutrients kept.

No oil, no direct heat on the surface — just enough moisture to kill what raw vegetables can carry, without breaking down the fiber and vitamins the way boiling does. Boiling leaches nutrients into the water you pour down the drain. Steaming keeps them in the vegetable, where your gut can actually use them.

It’s the gentlest method in this series, and for a reason: some vegetables — broccoli, leafy greens, delicate cruciferous veggies — hold onto more of their cancer-fighting compounds when they’re steamed instead of blasted with high heat.

Not the most exciting method. Possibly the most protective.

Three weeks in. One left.

A patient walked in last month convinced she had "leaky gut." She'd already cut gluten, dairy, and three other food groups — before we'd run a single test.

Here's the truth: the gut lining can become more permeable, disrupted by chronic stress, certain meds, infections, poor sleep. That part is real physiology.

What's not real: "leaky gut" as a catch-all diagnosis for acne, anxiety, autoimmune disease, and everything in between.

The symptoms are real. The label is usually wrong.

Bloating, fatigue, brain fog, skin flare-ups — these are often signs of something specific and treatable: IBS, SIBO, a food intolerance, thyroid dysfunction, inflammation.

Slapping "leaky gut" on top just delays finding the actual cause.

You don't need a self-designed elimination diet. You need a workup.

Don't self-diagnose off Instagram. Come in — let's find out what your gut is actually telling you.

08/20/2026

Your colon is doing a lot of work for you every single day.

The least you can do is feed it well.

As a colore**al surgeon, I operate on what goes wrong. But I spend just as much time talking to patients about what keeps things right — and food is near the top of that list.

The fiber in broccoli, kale, and spinach feeds the beneficial bacteria in your gut and keeps things moving.
The antioxidants in blueberries, strawberries, and tomatoes reduce inflammation in the colon lining.
The water content in cucumber and grapefruit supports digestion in ways most people underestimate.

None of this is complicated. It's not a cleanse or a protocol.

It's just produce. Consistently, over time.

I tell my patients the same thing I'll tell you: what you eat every day matters far more than what you do occasionally.

A green smoothie after a week of processed food isn't the goal. Building a diet where these foods show up regularly — that's the goal.

Your colon will notice the difference. So will the rest of you.

Week 2: Roasting.

Higher heat, drier method, same principle — you’re not just cooking flavor into your vegetables, you’re cooking risk out.

Roasting caramelizes the surface without needing much oil, so you get all the fiber and antioxidants with less fat than frying and more flavor than steaming. That fiber is still doing the same job: feeding the good bacteria in your gut and helping move waste through before it lingers.

The one thing to watch: don’t over-crowd the pan. Vegetables need space to roast, not steam. Give them room and a hot oven (400°F+), and you’ll get real texture with real benefit.

Two weeks down. Two to go.

With the produce outbreak still in the news, you know the why: cook your vegetables, protect your gut.

This week, we start the how.

4-week series: How to Cook Your Vegetables. One technique a week. One reason it matters for your colon.

Week 1: Sautéing.

A hot pan for a few minutes kills what raw washing can't — while keeping the fiber your gut bacteria depend on. That fiber helps clear abnormal cells before they become a problem.

Simple technique. Real protection.

Follow along all month.

It was an honor to meet with Governor Kathy Hochul and share my perspective as an independent physician and surgeon on the future of healthcare in New York.

We discussed the importance of protecting access to care and ensuring that independent physician practices can continue to thrive—because when physicians can remain independent, patients benefit from greater choice, personalized care, and stronger connections to their communities.

I’m grateful for the opportunity to advocate for my patients and for the physicians who serve them every day.

A patient asked me last week why her uncle got colon cancer at 45 when he “did everything right.”

Ran marathons. Ate clean. No family history.

The truth is there’s no single habit that guarantees protection.

But there are six that meaningfully shift the odds in your favor, and most people are only doing one or two of them.

Fiber does more than keep things moving. It feeds the bacteria in your gut that produce compounds linked to lower inflammation in the colon lining.

Exercise isn’t just about weight. Movement speeds up digestion, which means less time for anything harmful to sit against the colon wall.

Red meat isn’t off limits. It’s about frequency. A few times a week is different from a few times a day.

Smoking damages the cells lining your entire digestive tract, not just your lungs.

Alcohol gets broken down into acetaldehyde, a compound your body already classifies as a carcinogen.

And carrying excess weight, especially around the midsection, changes your hormone levels in ways that can fuel abnormal cell growth.

None of these habits are complicated. What’s complicated is doing all six consistently, for years, before you ever feel a symptom.

That’s the part screening can’t replace, but it’s also the part that makes screening matter more. Catch what habits alone can’t prevent.

If you’re 45 or older, ask about your first colonoscopy. If you’re younger with a family history, ask sooner.

Kinda chic.

Definitely kinda chic that I…

✨ Built my own practice.
✨ Lead a hospital division.
✨ Became the first female colore**al police surgeon for the NYPD.
✨ Am not afraid of difficult conversations.
✨ Believe prevention is always in style.

The titles are meaningful, but they were never the goal.

Building a practice where patients feel seen, heard, and cared for was.

Breaking barriers was a privilege. Earning my patients' trust is an honor.

Because at the end of the day, the title I'm proudest of isn't Chief, Director, or "the first."

It's simply being trusted by my patients. 💙
