I'm a Dietitian With a Grocery Cart Full of Opinions—Here's What Makes the Cut (and What Doesn't)
People assume that because I'm a registered dietitian, my cart looks like a farmers market exploded in it. Honestly? Half the time there's frozen pizza in there too. But after fifteen years of teaching clients how to shop, I've settled into a rhythm: a core list of foods that consistently earn their place, and a mental blocklist of products that are mostly marketing.
So come along on my typical Saturday run. I'll show you what I grab, what I deliberately walk past, and how to spot the difference without needing a nutrition degree.
The Produce Section: Where Half My Budget Goes
Frozen berries. Fresh blueberries in January cost a small mortgage payment and taste like damp cardboard. Frozen ones are picked at peak ripeness, flash-frozen within hours, and cost a third as much. They go straight into smoothies and oatmeal.
Cabbage. The most underrated vegetable in America. Two dollars, lasts three weeks in the fridge, and works shredded in slaws, seared in wedges, or simmered into soup. If budget is tight, cabbage is your friend.
Baby spinach and pre-shredded carrots. Yes, I pay for convenience here. A vegetable you actually eat beats a perfect vegetable that rots in your crisper drawer. If washing and chopping is the barrier between you and eating plants, spend the extra dollar.
Sweet potatoes. Cheap, versatile, loaded with fiber and potassium. I roast a big batch on Sundays and eat them all week.
The Aisles: My Pantry Non-Negotiables
Canned beans. If I could recommend only one pantry staple, it's this. Rinsed, they're cheap protein and fiber with a shelf life measured in years. Dried beans are more economical, but I've stopped pretending I always plan ahead.
Plain rolled oats. Not the cute single-serve packets with the flavoring—those can carry more added sugar than a cookie. A big canister costs pennies per serving.
Canned wild salmon and sardines. I know, I know. Hear me out: shelf-stable omega-3s and protein for under three bucks a can. Mash sardines with mustard and lemon on toast and thank me later.
Extra-virgin olive oil. One good bottle for finishing, one less-expensive one for cooking. You don't need the $30 artisanal import unless you want it.
Brown rice and dried lentils. The backbone of about a third of my weeknight dinners. Lentils cook in 25 minutes without soaking, which makes them the fastest protein in my pantry.
Plain Greek yogurt. The large tub, not the little cups. Buy the big one, add your own fruit, and save money and sugar in one move.
Eggs. Still the best protein-per-dollar deal in the store. I don't stress over carton color or fancy claims.
Frozen edamame and frozen peas. Two freezer staples that turn any sad grain bowl into a real meal.
Nut butter with exactly two ingredients. Peanuts and salt. That's the list. If the label reads like a chemistry quiz, put it back.
Whole-grain tortillas. Look for at least 4 grams of fiber per serving. Great for everything from breakfast wraps to quick pizzas.
Dark chocolate, 70% or higher. Yes, it makes the list. Sustainable habits include joy.
What I Leave on the Shelf
Now for the part that gets me in trouble at parties.
'Vitamin' waters and wellness beverages. Most are flavored sugar water wearing a lab coat. If you want electrolytes, eat a banana and drink tap water.
Anything labeled 'natural' as its main selling point. The FDA barely regulates that word on packaged goods. 'Natural' chips are still chips.
Single-serve snack packs of fruit or veggies. You're paying a 300% markup for slicing and a plastic sleeve. Buy whole, spend ten minutes on Sunday, done.
'Keto' or 'paleo' versions of cookies, breads, and brownies. Swapping wheat flour for almond flour doesn't turn a dessert into a health food—it just makes it an expensive dessert.
Fortified 'superfood' everything. Superfood popcorn. Superfood coffee creamer. Adding a dusting of chia to a junk food doesn't change what it is.
Three Label-Reading Shortcuts That Actually Work
- Read the ingredient list before the front of the package. The front is advertising; the back is disclosure. If sugar appears in the first three ingredients, you have your answer.
- Check the added sugars line, not total sugars. The sugar in plain yogurt or fruit isn't the concern—the six grams of added sugar in the flavored version is.
- Ignore the front, trust the fiber. As a rough rule, the more fiber per serving, the closer the food is to something your grandmother would recognize.
The Real Secret
Here's what I tell every client: the healthiest cart isn't the one with the trendiest products. It's the one full of foods you'll actually cook, actually eat, and can actually afford—week after week after week.
Fifteen items, most of them inexpensive, none of them exotic. That's it. That's the whole strategy. Now go shop like you mean it.
