A 371,000-Person Survey Linked Heart Conditions to Eating Less Whole Fruit — and Found No Clear Pattern for Juice

What the Researchers Looked At

The paper, published in Current Developments in Nutrition by Kesler, Hess, Bodensteiner, Palmer and Tande, and covered by News-Medical on September 28, 2026, uses data from the 2019 Behavioral Risk Factor Surveillance System (BRFSS). That's the large telephone health survey U.S. states run every year with the CDC. The analysis included 371,038 adults, drawn from an initial pool of 418,268 respondents.

BRFSS asks how often people eat whole fruit and drink 100% fruit juice, not how much. The researchers compared those frequencies between people who did and didn't report five conditions: high blood pressure, high cholesterol, a past heart attack, coronary heart disease (angina), and stroke. They adjusted for age, race and ethnicity, education, income, and smoking.

On average, respondents ate whole fruit about 1.06 times a day and drank fruit juice about 0.3 times a day. In other words, the typical adult in the survey had juice roughly two days out of seven.

What It Found

Whole fruit: after adjustment, people reporting high blood pressure, high cholesterol, coronary heart disease, or a previous heart attack ate whole fruit less often than people without those conditions. The direction was consistent. The authors themselves describe the differences in frequency as small.

Juice: this is where it gets interesting for anyone who juices. Once the adjustments were applied, juice frequency didn't differ for high blood pressure, stroke, or coronary heart disease. Two differences remained, and they pointed in opposite directions. People with high cholesterol drank juice less often, and people who'd had a heart attack drank it more often. The authors' own summary is that adjusted juice differences survived only for those two conditions, "in opposite directions."

So the study doesn't show juice is bad for your heart, and it doesn't show juice is good for it either. It found no consistent pattern at all.

Why You Shouldn't Read Too Much Into It

A survey like this can show that two things tend to show up together, but it can't show that one causes the other. The paper is upfront about that, and about several other limits:

• Diagnosis can change diet. Someone told they have high cholesterol may cut back on juice because a doctor suggested it. That would make juice look "protective" against high cholesterol when the arrow really runs the other way. The same reverse logic could explain why heart attack survivors drink more juice, for example if they swapped soda for juice after their diagnosis. The survey can't tell which came first.
• "Juice" may not mean juice. The authors note that respondents may count sweetened juice drinks as 100% juice. Fresh-pressed vegetable juice and a sugary juice cocktail can end up in the same answer.
• Frequency, not quantity. A 4-ounce glass and a 20-ounce bottle each count as one occasion.
• Missing pieces. The analysis didn't account for physical activity, body weight, vegetable or whole-grain intake, or other health conditions, and the authors say the sample isn't representative of the U.S. population.
• The data is from 2019. It describes habits from before the pandemic.

The paper also lists a disclosure: one author reported employment with VDF FutureCeuticals Inc., a company that makes fruit- and vegetable-based ingredients. That doesn't invalidate a survey analysis, but it's worth knowing.

What It Means If You Juice

Finding no clear pattern for juice doesn't mean juice and whole fruit are interchangeable. They aren't, and the study's whole-fruit result is consistent with what nutrition guidance has said for years. The U.S. Dietary Guidelines have long recommended that at least half of your fruit come from whole fruit rather than juice. The main reason is fiber. A juicer separates most of the fiber into the pulp bin, and fiber is one of the things that makes whole fruit filling and slows how fast its sugar reaches your bloodstream.

For a home juicer, that suggests a few practical habits:

• Treat juice as an addition, not a replacement. If a morning glass of juice is replacing the apple or orange you'd otherwise eat, you're trading away the fiber. Have both.
• Lean on vegetables. Celery, cucumber, leafy greens, and beets give you a big glass with much less sugar than an all-fruit juice. A green apple or half a lemon is usually enough for flavor. Our juice for blood pressure guide covers vegetable-forward recipes in detail.
• Keep fruit-heavy glasses small. An 8-ounce glass of orange or apple juice is a reasonable serving. A 16-ounce glass of it isn't.
• Put the pulp back to work. Stirring some pulp into oatmeal, muffins, or soup recovers part of the fiber the juicer removed. See our juice pulp recipes.
• Blend when fiber is the goal. A smoothie keeps the whole fruit. Our juicing vs. blending comparison explains when each makes more sense.

If you already have high blood pressure, high cholesterol, or heart disease, or you take medication for any of them, check with your doctor or a dietitian before making juice a daily habit. Some produce interacts with common medications. Grapefruit and statins are the best-known example, and potassium-rich juices can matter for people on certain blood pressure drugs.

The Bottom Line

• A Current Developments in Nutrition analysis of 371,038 adults from the 2019 BRFSS found people with high blood pressure, high cholesterol, coronary heart disease, or a past heart attack ate whole fruit slightly less often.
• For 100% fruit juice, there was no consistent pattern. After adjustment, juice was less frequent with high cholesterol, more frequent after a heart attack, and no different for the other conditions.
• The study is cross-sectional, measures frequency rather than amount, may count sweetened drinks as juice, and can't show cause and effect.
• The practical takeaway matches long-standing advice: let juice add to whole fruit rather than replace it, keep fruit-heavy glasses small, and make vegetables the base of your juices.

This study is a reminder that the form fruit comes in matters, not a verdict on juicing. The most heart-friendly version of a juicing habit is a vegetable-heavy glass alongside a piece of whole fruit, rather than in place of it.
