If Everything Is So Good for Us, Why Are We All So Sick?

Updated July 2026

Walk into any grocery store and you're surrounded by products shouting health claims: reduced sodium, helps lower cholesterol, only 100 calories per serving. And yet, as a cardiologist, my days are spent treating high blood pressure and high cholesterol in people who are struggling to lose weight. If the shelves are so full of healthy food, why are we so un-healthy?

The answer is that most of those messages are marketing claims, not nutrition guidance — engineered to win a purchase decision that's made in three to five seconds. This post walks through the three things shoppers typically rely on to judge a food: the claims on the front, the ingredient list, and the nutrition panel. Each can mislead you. Then I'll show you how to shop past all of it.

Can you trust the health claims on the front of the package?

Usually not, because those claims are built to sell, not to inform. "Reduced sodium" only means a product has at least 25% less than a reference version — not that it's actually low in sodium. Campbell's regular condensed chicken noodle soup carries 890 mg of sodium in a half-cup serving; the "25% less sodium" version still lands around 660 mg. That's more than a quarter of the day's recommended sodium in a small bowl of soup, and closer to 44% of the stricter 1,500 mg limit advised for people with high blood pressure. "Reduced" is not the same as "appropriate."

"Helps lower cholesterol" works the same way — it leans on one ingredient's documented effect in a context that has little to do with the actual product. The soluble fiber in oats can lower cholesterol, but by the manufacturer's own math the amount tied to that benefit is 3 grams a day, and a serving of Honey Nut Cheerios provides just 0.75 grams. You'd have to eat four bowls to get there — along with roughly 560 calories, twelve teaspoons of added sugar, and about a third of a day's sodium. The added sugar alone works against you: it drives up insulin, and higher insulin means more LDL production. The beneficial ingredient is buried under the harmful ones. And despite the name, there's not a nut in the box — just almond flavoring.

Calorie callouts work the same way. A 100-calorie pack of Oreo Thin Crisps sounds harmless, but an extra 100 calories a day adds up to roughly ten pounds in a year — and those are empty calories, with no fiber, no healthy fats, no antioxidants, nothing that builds health.

Even trusted symbols deserve scrutiny. The American Heart Association's Heart-Check mark is a good example: it isn't the result of the AHA scouring the store for the healthiest foods — manufacturers pay to carry it, between about $3,000 and $6,000 per product every year. There are nutrition standards to qualify, but they leave room for processed products. And the Heart-Check is only one of many: whole grain, multigrain, vegan, and on and on. The great irony is that the healthiest things in the store — the fruits and vegetables — carry no symbols at all. If a package is crowded with them, it's usually a clue the food inside is highly processed.

Does the ingredient list tell you the truth?

It should, and it's more tightly regulated than the front of the box — but manufacturers have learned to game it. The rule is simple: ingredients are listed in order of weight, heaviest first. The tricks are how companies get around it.

The first is ingredient splitting. When a product contains several kinds of sugar, each can be listed separately, so no single one lands near the top — even if, added together, they'd outweigh almost everything else. A popular jar of honey-roasted peanuts, for instance, lists sugar, honey, corn syrup, and fructose as four separate ingredients; combine them and there may be more sweetener than you'd ever guess sits in a can of nuts.

The mirror image is combining. The rules also let a company fold several components under one wholesome-sounding umbrella, so that phrase can sit high on the list while what it represents stays vague. Grouping half a dozen grains into a single "whole grain blend" keeps that reassuring phrase near the front — where, broken into its parts, some component might rank below an added sugar you'd rather not see up top. When a brand stops doing this, the truth reappears: some granolas now list each grain on its own, and the sugar quietly climbs to where it really belongs — at or near the top.

Put both tricks together and labels become nearly impossible to read honestly. A strawberry protein bar can list sugar in several forms at once — plain sugar, corn syrup, fructose, and still more sugar inside the fruit pieces — while the "strawberry" pieces themselves turn out to be flavored dried cranberries. There isn't a strawberry in it. The takeaway holds regardless of the product: the shorter the ingredient list, and the more of it you recognize as real food, the better.

What about the nutrition facts panel?

It helps less than you'd think, because it describes macronutrients, not food quality. Picture two panels side by side. One has a bit more fiber; the other has less sugar, more protein, and a full day's vitamin C. It looks like a close call — until you learn the first panel is an apple and the second is eight gummy bears. On paper they look interchangeable. In your body they are nothing alike.

That's the flaw in reading the panel alone: there is far more to an apple than its grams of fat, sugar, and protein, and there is almost nothing to a gummy bear beyond sugar. Hitting 100% of a vitamin tells you nothing about whether the food carrying it is good for you. The panel has genuinely improved — it now breaks out added sugars on their own line, which helps — but it still can't tell you whether what you're holding actually builds health.

How do you actually shop well, then?

You lean on a handful of habits that cut through all of it. Start with whole foods, which need no claims, lists, or panels at all — produce, herbs, leafy greens, naturally rich in fiber and micronutrients and naturally free of added sodium and cholesterol. When you do buy packaged food, treat loud front-of-box claims as a reason for skepticism, not a reason to buy. Keep ingredient lists short and recognizable; the more a list reads like a chemistry set, the less you want it, and heavy fortification with added vitamins often signals a food that had little nutrition to begin with. Watch for the splitting and combining tricks. Check sodium against a target of under 2,300 mg a day — or 1,500 mg if you have high blood pressure — and check the serving size it's based on, which is often unrealistically small. Favor fiber from whole foods over additives like inulin, chicory root, or maltodextrin. Be skeptical of high-protein labeling, since most of us already get plenty and those products tend to be heavily processed and sweetened. And be curious about a suspiciously cheap packaged food: if it costs little, little was likely spent on what's inside.

One old rule of thumb has thankfully expired. For years the advice was to scan for "partially hydrogenated" oils, the source of artificial trans fat. That battle is essentially won — the FDA ruled those oils unsafe and they've been cleared from the food supply since 2021. Two small footnotes remain: a label can still say "0 grams trans fat" with up to half a gram per serving, and trace amounts occur naturally in some meat and dairy. But hunting for hydrogenated oils is no longer the chore it once was.

So why are we all so sick?

Because the food environment is built to sell health, not to deliver it — and the shopper is left to referee. That gap is exactly why I created Step One Foods: real ingredients, honest formulation, and a clinical trial behind the results, rather than another claim on another box. There's no shortage of marketing. There's a shortage of food that delivers on the promise and is actually proven to build health.
