TL;DR: A six-month study found that changing how much sweet-tasting food you eat doesn’t change how much you like sweetness, and it didn’t improve heart or diabetes risk markers. The real issue? Sugar and calorie-dense foods—not sweet taste itself.
Have you ever heard advice like "Cut out sweet foods and you’ll stop craving them"? It sounds logical—like turning down the volume on a radio. But a new study published in the American Journal of Clinical Nutrition suggests our taste buds don’t work that simply.
Researchers from Wageningen University (Netherlands) and Bournemouth University (UK) put this idea to the test—and the results might surprise you.
Participants were randomly split into three groups, each following a different diet:
| Group | Sweetness Level | What They Ate |
|---|---|---|
| High Sweetness | Lots of sweet-tasting foods | Foods sweetened with sugar, natural sugars (like fruit), and low-calorie sweeteners |
| Low Sweetness | Very little sweet-tasting food | Minimal sweet flavors from any source |
| Average Sweetness | Typical amount of sweetness | A normal, balanced diet with moderate sweet foods |
Important: The sweet taste came from three different sources—not just sugar! This matters because:
- Fruit = natural sugar + fiber + vitamins
- Diet soda = low-calorie sweetener + no sugar
- Candy = added sugar + little nutrition
At 1 month, 3 months, and 6 months, they checked:
After the study ended, most participants naturally returned to their usual sweet food intake—suggesting forced changes don’t stick.
Key Insight: Sweetness ≠ Sugar
| Concept | What It Means | Example |
|---|---|---|
| Sweetness | A taste sensation | Strawberries, stevia, honey, candy |
| Sugar | A nutrient (carb) that adds calories | Table sugar, high-fructose corn syrup |
| Energy-Dense Foods | Lots of calories in a small portion | Fries, donuts, fast-food burgers |
Professor Katherine Appleton (Lead Researcher):
"It’s not about eating less sweet food to reduce obesity. The health concerns relate to sugar consumption and energy-dense foods. Public advice needs to focus on reducing added sugars and calorie-packed processed foods—not sweet taste itself."
Think of it like packing a suitcase:
Many ultra-processed foods are both energy-dense AND low in nutrients—a double whammy.
| Supported by Study | Not Supported |
|---|---|
| Sweet taste preference is stable—it doesn’t shrink or grow based on exposure | Cutting sweet foods "resets" your taste buds |
| Sugar and calorie density matter more for health than sweetness | All sweet-tasting foods are bad |
| Naturally sweet foods (fruit, dairy) can be part of a healthy diet | You must avoid sweetness to be healthy |
| Dietary advice should target added sugar and processed foods | Blanket "reduce sweetness" recommendations |
Probably not. This study found that even after six months of low sweetness, people’s liking for sweet taste didn’t decrease. Cravings are complex—habit, emotion, and biology all play roles.
They’re different. Low-calorie sweeteners give sweetness without sugar’s calories or blood sugar impact. But this study didn’t test long-term effects of sweeteners alone—just sweet taste from mixed sources.
Absolutely not! Fruit has natural sugars + fiber + water + vitamins. It fills you up and supports health. The study included fruit in the high-sweetness group—and still found no harm.
Focus on:
No. The study says sweet taste isn’t the villain—excess sugar and calories are. A donut and an apple both taste sweet. One nourishes you; the other spikes blood sugar and leaves you hungry.
Bottom Line: Your sweet tooth isn’t a volume knob you can turn down by force. Instead of fighting your biology, outsmart your environment—choose whole foods, watch for hidden sugars, and don’t fear the natural sweetness of real food.
Science doesn’t say "eat more candy." It says: "Blame the sugar, not the sweetness."
