As FDA Targets Added Sugars, Researchers Warn on Limits of ‘Healthier’ Reformulated Foods

As U.S. regulators move to push manufacturers to cut added sugars from packaged foods, a growing body of research suggests that reformulated “lower sugar” products can reduce sugar intake and body weight, yet still leave consumers eating energy-dense, ultra-processed diets.

The U.S. Food and Drug Administration’s Human Foods Program plans to release a national “added sugar reduction strategy” in 2026, focusing on encouraging industry-wide reformulation across popular packaged foods and beverages, according to an agency roadmap published this year.1 The initiative dovetails with the forthcoming 2025–2030 Dietary Guidelines for Americans, which emphasize cutting added sugars and refined grains as key levers for improving diet quality, Harvard nutrition experts say.2

At the same time, new and recent reviews highlight both the promise and the pitfalls of relying on product reformulation as a cornerstone public health strategy — especially when sugar is replaced with additives, sweeteners and starches in foods that remain ultra-processed and nutrient-poor.34

Clinical evidence: Reformulated products lower sugar intake and weight

A systematic review and meta-analysis of randomized controlled trials, published in Nutrients, found that consumption of reformulated foods and drinks led to significant reductions in sugar intake and modest but meaningful decreases in body weight.5

Pooled estimates from the trials showed:

  • An average 11.18% reduction in percentage of sugar intake (95% CI, -19.95 to -2.41; P < 0.00001).
  • A 91 g/day lower total food intake (95% CI, -119.75 to -62.25).
  • A 0.8 kg reduction in body weight, on average, among participants consuming reformulated products, compared with controls (figures reported in the review).5

The findings support the view that gradual, behind-the-scenes reformulation — reducing sugars, fats or salt without requiring consumers to actively choose “diet” products — can shift population intakes.[^reform-effective]

Modeling work published in Scientific Reports has also suggested that broad, across-the-board reductions in added sugars in processed foods could yield measurable declines in obesity and related disease burden, though the projections depend heavily on assumptions about taste, acceptance and consumption patterns.6 That study did not test the sensory properties of reformulated foods, the authors noted, and assumed consumers would continue buying and eating the products at similar levels.

Industry responds: ‘Better-for-you’ launches accelerate

Food and beverage companies have moved aggressively into what they describe as “better-for-you” categories, reformulating existing brands and developing new lines that promise reduced sugar while maintaining familiar taste and texture.7

Global manufacturers are increasingly deploying blends of high-intensity sweeteners, fibers, polyols and bulking agents to rebuild sweetness and mouthfeel as sucrose is reduced, according to a recent industry analysis of sugar-free and sugar-reduced innovation.74 These approaches aim to preserve brand identity and consumer trust as labels shift from full-sugar to reduced-sugar versions.

Private-label products sold by major grocery retailers are undergoing similar changes. A survey of U.S. retailers reported widespread reformulation to lower added sugars, alongside more prominent “better-for-you” labeling, shelf tags and online filters for attributes such as “no added sugar,” “organic,” or “high fiber.”8

Public health advocates describe this type of “stealth” reformulation as a way to reduce population sugar intake without making shoppers scrutinize every label. Healthy Food America, a nonprofit focused on sugar reduction, estimates that 68% of all processed foods in the U.S. contain added sugars, making voluntary or regulated reformulation an attractive lever for systemic change.9

Public health push: Roadmaps and guidelines favor reformulation

Several major organizations now frame added-sugar reformulation as a priority tool for chronic disease prevention.

A 2023 “roadmap” from the Center for Science in the Public Interest (CSPI) calls on the U.S. food and beverage industry to gradually ratchet down added sugars across product categories, arguing that incremental changes over time can lower intake while keeping products palatable and commercially viable.10 The report outlines category-specific targets and timelines, modeled in part on sodium reduction frameworks used abroad.

The forthcoming 2025–2030 Dietary Guidelines for Americans are expected to retain or strengthen current recommendations to limit added sugars to less than 10% of daily calories. Frank Hu, chair of the Department of Nutrition at the Harvard T.H. Chan School of Public Health, said the new guidelines “move in the right direction by reinforcing the importance of reducing added sugars and cutting back on refined grains and other highly processed foods.”2

Reformulation is also gaining traction in broader nutrition policy discussions. A comprehensive review in Food Policy describes reformulation as a key strategy to lower salt, sugar and unhealthy fats and to boost fiber and micronutrients in processed foods, though the authors stress that its effectiveness depends on how extensively and equitably it is implemented across the food supply.11

Scientific caution: ‘Lower sugar’ does not mean nutritious

While reformulation appears effective at reducing sugar intake in clinical trials and models, several experts warn that “low sugar” labels do not automatically translate into healthier diets.

A recent critical review of sugar reformulation in solid foods, published in Nutrients, argues that many sugar-reduced products remain energy-dense and nutrient-poor.3 To maintain texture, bulk and shelf stability, manufacturers often replace sugar with refined starches, fats and a suite of additives — including non-nutritive sweeteners, emulsifiers and stabilizers — that can leave the overall nutritional profile relatively unchanged.

The authors note that this “plethora of ‘lower sugar’ nutrient-poor products” may give consumers a health halo impression while doing little to improve overall dietary quality. In many cases, they write, reformulated foods stay within the NOVA-4 “ultra-processed” category, which has been independently linked to higher risks of obesity, cardiovascular disease and all-cause mortality in observational studies.

A perspective in npj Science of Food goes further, arguing that current quantitative sugar guidelines may be too narrowly focused on grams of sugar rather than the degree of processing and overall food matrix.4 The authors point out that many products targeted for sugar reformulation are already ultra-processed, and that swapping sugar for artificial sweeteners can push some minimally processed foods into the ultra-processed category.

They suggest that policy should more explicitly consider how reformulation affects processing level, ingredient complexity and food structure, not just sugar content alone.

Ultra-processing and metabolic risk: Sugar is only one piece

Scientific debates over sugar reformulation intersect with a wider controversy about the health impacts of ultra-processed foods.

A 2025 review in Frontiers in Nutrition highlights an emerging “disconnection” between sugar reduction and total calorie reduction in some reformulated products.12 While cutting sugars can lower glycemic load, manufacturers may compensate with added fats or refined starches, keeping energy density high. The review notes continuing controversies over the role of sugars in obesity and cardiometabolic disease, with meta-analyses showing mixed results depending on study design and the nutrients that replace sugar.12

Separately, a 2021 review of sugar reduction in baked goods, published in Food Research International, documented the technological challenges of lowering sucrose in items such as cakes, biscuits and pastries.13 Because sugar contributes to browning, volume, tenderness and moisture retention, its removal often requires combinations of bulking agents, fibers and sweeteners — changes that can alter not only taste but also digestibility and satiety.

The Food Research International authors conclude that while reformulation is technically feasible, it frequently relies on higher levels of processing and novel ingredients that may have uncertain long-term health impacts when consumed at scale.13

Consumer acceptance: Taste, texture and trust drive real-world impact

Whether reformulation delivers on public health goals ultimately depends on consumer response.

A quantitative study by Markey, Lovegrove and Methven, published in Nutrients, examined how consumers rated regular versus sugar-reduced versions of baked goods, yogurts and soft drinks that used sweeteners to replace sugar.14 The researchers reported that:

  • Acceptance of sugar-reduced products varied significantly by category.
  • Moderate sugar reductions were generally tolerated when taste and texture were preserved.
  • Larger reductions, or pronounced changes in mouthfeel, led to noticeable drops in liking and purchase intent.

The study underscores a challenge acknowledged in multiple modeling and policy analyses: if consumers reject reformulated products or compensate by consuming larger portions, the projected health benefits may be diluted.611

Industry analysts say brand equity and transparent communication are key. Reporting in FoodNavigator suggests companies are testing gradual, stepwise sugar reductions to allow consumer palates to adjust over time, while closely monitoring reactions to reformulated recipes.7

Policy crossroads: Reformulate, regulate — or rethink the food environment?

As FDA staff develop the agency’s 2026 added sugar reduction strategy, researchers and advocates are debating how far reformulation alone can go.

Proponents argue that population-wide sugar cuts achieved through industry-wide targets may be one of the most scalable, cost-effective ways to lower risk for diabetes, heart disease and obesity, particularly in communities with limited access to fresh foods.911 Reformulation, they note, does not require consumers to change their habits overnight.

Skeptics counter that focusing narrowly on grams of added sugar risks entrenching an ultra-processed food system, now lightly re-engineered but still dominated by industrial formulations. They call for complementary strategies that include:

  • Incentives for minimally processed, nutrient-dense foods.
  • Restrictions on marketing of ultra-processed, sugar-reduced products to children.
  • Clearer front-of-pack labeling that conveys both sugar content and processing level, rather than a single nutrient metric.43

Future clinical trials and real-world evaluations of sugar-reduction programs may help clarify these trade-offs. For now, the science suggests that reformulation can successfully lower sugar intake and weight at the individual level — but may not, on its own, transform the broader nutritional landscape unless it is paired with deeper changes to what is produced, promoted and made most affordable across the U.S. food supply.
