Blood work
98% of Americans aren’t getting enough of this one nutrient.

The Brief
Welcome back, Wellworthy readers.
The CDC just released its biggest nutrition report ever.
Tracking what Americans ate over the past 25 years, the findings reveal some surprising nutrition gaps, along with a few signs diets may finally be moving in the right direction.
This week, we're breaking down what it means for your plate.
Here’s what’s inside:
The surprising nutrient nearly all Americans are missing
WHOOP wants to make fertility tracking easier
FRESH THIS WEEK: A ring watch health tracker, teeth-cleaning foam, and running music mixed just for you
Here we go!
— Jake & Joana

The Breakdown
The CDC just gave us one of the clearest pictures yet of how Americans are actually eating.
Instead of asking people what they eat, researchers analyzed blood samples to measure nutrient levels directly.
One finding stood out: Nearly 98% of Americans aren't getting enough omega-3s.
Why it matters
Omega-3s are essential fats that support brain, heart, and eye health. Because your body can’t produce them on its own, you need to get them from food or supplements.
Vitamin D tells the opposite story. As awareness around the nutrient has grown, so have blood levels, but people may be overdoing it. The number of Americans with excess vitamin D jumped from under 1% to 8%, mostly due to supplement use.
The takeaway
Nutrition trends come and go, but the basics matter. Foods rich in omega-3s like salmon, walnuts, chia seeds, and ground flax are ways to work more into your day, and if you're curious where your levels actually stand, it's worth bringing up with your doctor at your next visit.

The Health Stack: Belle Robinson
Belle Robinson is a nutritionist, wellness expert, and founder of Roxii Supercube. After years of helping clients navigate complicated wellness routines, she set out to create a hydration brand that fits naturally into everyday life.

Belle Robinson, nutritionist and founder of Roxii Supercube.
What changed: Working with clients showed Robinson that consistency beats perfection. She saw too many people give up on complicated wellness routines, which changed the way she thought about health. The healthiest routine, she believes, is the one you'll actually stick with.
How she thinks about wellness: Robinson believes wellness has become "incredibly noisy," with a product for every problem and a protocol for every goal. Real progress, she says, comes from consistency, not adding more.
Her advice: Stop chasing perfection. Focus on habits you can repeat, even on your busiest days. As Robinson puts it, "The best wellness solutions are the ones that make healthy choices feel easier, not harder."
Her stack:
For making hydration effortless, Robinson created Roxii Supercube.
She wears an Oura Ring every day to better understand her recovery.
A BrüMate bottle makes it easier for her to stay hydrated.
Her favorite afternoon snack? Mid-Day Squares.
Instead of a sugary coffee drink, she reaches for a Kroma Wellness Matcha Latte.

Health tech & self-care
Hatch’s new Sleep Clock monitors your sleep, breathing, and bedroom environment using contact-free radar. Instead of “grading” how you slept last night, it focuses on long-term sleep patterns and personalized recommendations to shift away from the score obsession. Meet the Sleep Clock.
EMRA is joining the growing focus on oral health, but not with another toothpaste. Instead, it created a teeth-cleaning foam that pumps directly into your mouth to freshen breath while helping remove food particles and surface stains. It's made for after lunch, coffee, or long travel days. Oh, and it comes in a unique flavor: Kiwi Cactus. Freshen up.
Casio squeezed a fully functional biometric health tracker into its iconic Ring Watch. The tiny wearable still lets you check the time and calendar from your finger, but now it also tracks heart rate, sleep, blood oxygen, body temperature, and activity. It's one of the few smart rings with a built-in display instead of relying entirely on an app. Take a look.
