The Short Answer
Most conventional store-bought salad dressings are terrible for your health. While you think you're making a healthy choice by eating a salad, the dressing is often turning it into a hyper-palatable junk food.
The biggest issue is what makes up the base of the bottle. Up to 40% of a standard dressing is made of highly refined seed oils like soybean or canola oil. Combine that with hidden sugars and chemical stabilizers, and your two tablespoons of dressing might be doing more harm than the leafy greens do good.
Why This Matters
We've been conditioned to fear the fat in salad dressings, which led to the boom of "fat-free" options. But fat-free dressings are often the worst offenders on the shelf. When manufacturers remove the fat, they pump the bottle full of sugar and thickeners so it doesn't taste like flavored water. Check out Sugar In Salad Dressing to see how bad the math gets.
The oils used in standard dressings are another massive red flag. Soybean and canola oil are incredibly cheap, which is why they are the first ingredient in almost every commercial dressing. These highly processed oils are rich in omega-6 fatty acids, and consuming them in large, disproportionate amounts is linked to chronic inflammation. We break this down further in Oils In Salad Dressing.
Finally, the chemical load in creamy dressings is alarming. Many brands use artificial dyes and whitening agents to make dressings look more appetizing. If your dressing is stark white, it likely contains titanium dioxide, a chemical that the European Union banned from foods in 2022 due to DNA damage concerns.

What's Actually In Salad Dressing
- Soybean Oil — The cheapest and most common base for commercial dressings. It is highly refined and heavily linked to systemic inflammation. Oils In Salad Dressing
- Added Sugar — Used to balance acidity and mask the lack of fat. Some fat-free vinaigrettes contain up to 13 grams of sugar per serving. Sugar In Salad Dressing
- Titanium Dioxide — A synthetic whitening agent used in ranch and blue cheese. It is banned in Europe for causing potential DNA damage, but still legal in the US.
- Calcium Disodium EDTA — A preservative used to protect flavor and color. It's safe in small amounts but completely unnecessary in fresh, real food.
- Xanthan Gum — A harmless thickener. Its presence usually means the dressing lacks real, emulsifying ingredients like egg yolks or mustard.
What to Look For
Green Flags:
- Extra virgin olive oil or avocado oil — These should be the absolute only oils listed on the bottle.
- Zero added sugar — Natural sweetness should come strictly from balsamic vinegar or a touch of fruit.
Red Flags:
- "Vegetable oil" blends — This is sneaky industry code for cheap soybean and canola oil.
- Fat-free labels — This is almost always a guarantee of high sugar content and synthetic thickeners.

FAQ
Is ranch dressing always bad for you?
Conventional ranch is a nutritional disaster. It is almost entirely soybean oil, buttermilk powder, and artificial stabilizers. However, clean brands are now making fantastic ranch options with avocado oil and real egg yolks. Read more in Is Ranch Dressing Bad.
Why do they put sugar in salad dressing?
Sugar acts as a cheap flavor enhancer and balances the harsh acidity of low-quality vinegars. It is especially high in fat-free dressings to replace the mouthfeel and satisfaction that fat normally provides.
Are vinaigrettes healthier than creamy dressings?
Not necessarily. A vinaigrette made with soybean oil and 10 grams of high-fructose corn syrup is actually worse than a clean creamy dressing. Always check the ingredients, regardless of the dressing style. Learn more in Oil Based Vs Creamy Dressing.
