What appears to be a healthy meal choice – a simple salad – can be surprisingly detrimental to health goals due to hidden sugars and sodium in many store-bought dressings. A new investigation reveals that commercially prepared salad dressings are frequently loaded wiht additives and flavor enhancers, even those marketed as “light” or low-fat. Experts are raising concerns about the prevalence of “ultra-processed” foods in the American diet, and this report underscores the importance of carefully examining ingredient labels-or, better yet, making dressings from scratch.

A simple salad, a few raw vegetables, and a drizzle of dressing seem like a healthy choice. However, a recent investigation reveals that many commercially prepared salad dressings transform what could be a nutritious meal into a surprisingly high-sodium and high-sugar experience. The findings highlight a growing concern about “ultra-processed” foods and their impact on public health, as even dressings labeled “light” can contain hidden ingredients that detract from their nutritional value.
While a homemade vinaigrette typically consists of just oil, vinegar, and a touch of mustard, the ingredient lists on store-bought versions are often lengthy and filled with unfamiliar terms. This complexity can be misleading for consumers seeking a healthy option.
Additives, Salt, and Sugar: What the Investigation Reveals
Beyond oil and vinegar, many commercially available dressings contain ingredients like xanthan gum, carrageenan (E407), modified starch, pea protein, and guar gum. “They have no nutritional benefit; they are markers of ultra-processed foods,” explained registered dietitian nutritionist Caroline Bataillard. “Their use is perplexing, especially considering how easy it is to make a vinaigrette at home,” she added. The investigation underscores the importance of reading ingredient labels carefully.
Analysis of the dressings showed consistently high salt content, with none containing less than 1 gram of salt per 100 ml, and some exceeding 3 grams per 100 ml. The World Health Organization recommends adults consume less than 5 grams of salt per day. Similarly, even “light” versions often contain nearly 7.5 grams of sugar per 100 ml. “Sugar and salt are flavor enhancers,” noted dietitian Marina Devillierse.
Why Pre-Made Dressings Often Fall Short Nutritionally
Vinaigrettes are inherently unstable emulsions – oil naturally separates from vinegar. To maintain a consistent appearance, manufacturers add texture stabilizers and sometimes colorings. While these additions improve shelf life, they also categorize the dressings as ultra-processed foods. This reflects industrial practices rather than traditional cooking methods.
Furthermore, “light” dressings frequently list water as the primary ingredient, without necessarily reducing salt or additives. Sugar is often added to compensate for lost flavor. Even dressings that appear relatively healthy can contain around 472 kcal per 100g, or approximately 71 kcal per tablespoon (15g). This means that seemingly innocent salad dressings can quickly add calories to a meal.
Choosing a Healthier Salad Dressing
When shopping for salad dressing, a few simple strategies can help consumers make better choices. The goal isn’t necessarily to eliminate these products entirely, but to be more informed. Here’s what to look for:
- Prioritize a short ingredient list featuring recognizable “kitchen” ingredients: oil, vinegar, mustard, and herbs.
- Avoid long lists of additives like xanthan gum, carrageenan (E407), modified starch, and guar gum.
- Look for canola or olive oil listed first, rather than water.
- Be wary of “light” claims, as they may indicate a higher sugar content and elevated salt levels.
The healthiest option remains a homemade vinaigrette: simply combine canola or olive oil, vinegar, and a touch of mustard. This avoids added sugar and artificial ingredients. Preparing it in advance and shaking well before serving ensures optimal flavor and freshness. By using reasonable portions, you can adhere to WHO guidelines without sacrificing taste.
