Ranch dressing: the dip helps the salad more than the child

Ranch is sold as the thing that gets vegetables eaten. The strongest evidence on this page says the opposite for small children. A meta-analysis of 44 intervention arms in 4017 preschoolers aged 2 to 5 found vegetable intake rose more when vegetables were offered plain and tasted repeatedly. Pairing them with a dip, a flavour or added energy did less. The one trial that favours the dip is narrower. In 152 Head Start preschoolers, with classrooms randomised to four dip conditions over 7 weeks, children sensitive to bitter taste ate 80 percent more raw broccoli with a salad-dressing dip, and bitter-insensitive children ate no more with it. What a full-fat dressing does reliably is carry fat, and fat is what moves carotenoids out of a salad and into blood. In 7 healthy adults, a fat-free dressing gave essentially no carotenoid absorption from a single salad, and 28 g of canola oil beat 6 g. In 29 healthy adults, 20 g of fat with a salad raised absorption above 3 g and 8 g, and whether that fat was canola oil, soybean oil or butter mattered less than how much there was. None of these trials used ranch. They used plain oils in single meals, and in a 12-woman dose study with 0 to 32 g of soybean oil some individuals showed a negligible response to any amount.

What your body absorbs

• In 12 women, absorption of carotenoids and vitamin K from a salad rose linearly with 0 to 32 g of soybean oil in the dressing and was highest at 32 g, while some individuals showed almost no response to the oil. — 12 women, crossover, 5 salads with dressings containing 0, 2, 4, 8 or 32 g soybean oil (n = 12) Evidence B source
  Linear dose response for alpha-carotene, lycopene, phylloquinone and retinyl palmitate across 0-32 g; all highest at 32 g (P < 0.002); wide interindividual variation
• In 29 adults, 20 g of fat with a salad raised carotenoid absorption above 3 g and 8 g, and the amount of fat mattered more than whether it was canola oil, soybean oil or butter. — 29 healthy adults, 3 x 3 Latin square crossover, salads with 3, 8 or 20 g of canola oil, soybean oil or butter (n = 29) Evidence B source
  20 g above 3 and 8 g for all carotenoids (p < 0.05); lipid source had less impact than amount
• In 16 adults, eating a carotenoid-rich salad with 28 g of emulsified fat gave a 40% larger 10-hour rise in plasma carotenoids than the same fat unemulsified, and olive oil beat coconut oil by 55% for total carotenoids. — 16 adults, crossover, identical salad with 28 g of emulsified or non-emulsified olive or coconut oil, plasma sampled hourly for 10 h (n = 16) Evidence B source
  Emulsified fat: +40.0% positive iAUC1-10h of total carotenoids; olive oil vs coconut oil: +55.2% total carotenoids, +110.8% alpha-carotene, +45.8% lycopene

Safety, limits and interactions

• In 104 139 French adults followed for a mean 6.8 years, each extra 500 mg per day of xanthan gum (E415) was associated with an 8% higher risk of type 2 diabetes, and guar gum (E412) with 11%. — 104 139 adults of the NutriNet-Sante cohort, 2009-2023, mean age 42.7, 79% women, 1056 incident type 2 diabetes cases (n = 104 139) Evidence C source
  Xanthan gum HR 1.08 (95% CI 1.02-1.14) per 500 mg/day; guar gum HR 1.11 (1.06-1.17) per 500 mg/day; carrageenans HR 1.03 (1.01-1.05) per 100 mg/day
• In 95 442 French adults followed for a median 7.4 years, higher intake of mono- and diglycerides of fatty acids (E471 and E472) was associated with higher cardiovascular risk. Celluloses carried a 5% higher CVD risk per standard deviation of intake. — 95 442 adults of the NutriNet-Sante cohort without prevalent CVD, 2009-2021, median follow-up 7.4 years, 1995 incident CVD events (n = 95 442) Evidence C source
  Celluloses (E460-E468): HR 1.05 (95% CI 1.02-1.09) per 1 SD for CVD; E471 and E472 associated with higher risks of all outcomes; E472b: CVD HR 1.06 (1.02-1.10)
• In 60 healthy adults, 4 weeks of added carboxymethyl cellulose, polysorbate 80, carrageenan or soy lecithin did not change faecal calprotectin, C-reactive protein or cholesterol versus placebo, while carrageenan raised transcellular permeability from baseline. — 60 healthy adults, 2-week emulsifier-free diet then 4 weeks randomised to one emulsifier or placebo delivered in brownies, double-blind (n = 60) Evidence B source
  No difference vs placebo in calprotectin, CRP, LBP, cholesterol or metabolic markers; lower short chain fatty acids with carboxymethyl cellulose; carrageenan: transcellular permeability up vs baseline (P = .04)
• FDA's voluntary sodium reduction goals (Edition 2) list restaurant salad dressings, explicitly including ranch dipping sauces, at a 2022 baseline of 845 mg sodium per 100 g with a target mean of 550 mg and an upper bound of 870 mg. Packaged salad dressings sit at 762 mg baseline, 550 mg target and 790 mg upper bound per 100 g. — US food supply, restaurant and packaged salad dressing categories 18-R and 18-P Evidence E source
  Baseline 845 mg/100 g (restaurant) and 762 mg/100 g (packaged); target mean 550 mg/100 g; upper bound 870 and 790 mg/100 g
• Across six NHANES cycles from 1999 to 2010, salad dressing was the only food group whose contribution to US adults' sodium intake rose in four consecutive survey cycles compared with 1999-2000. — US adults in six NHANES cycles 1999-2010, food groups by USDA food code Evidence C source
  Salad dressing contribution to sodium intake increased in four consecutive cycles vs 1999-2000; most other food groups unchanged

What people believe that the data does not support

• In 7 adults, a salad eaten with fat-free dressing gave negligible carotenoid absorption, and a dressing with 28 g of canola oil gave more absorption than one with 6 g. — 7 healthy adults, crossover, 3 salads with dressings containing 0, 6 or 28 g canola oil (n = 7) Evidence B source
  Fat-free: negligible chylomicron carotenoids; reduced-fat above fat-free (P < 0.04); full-fat above reduced-fat (P < 0.02)
• A meta-analysis of 44 intervention arms in 4017 children aged 2 to 5 found vegetable intake rose more with repeated tasting of plain vegetables than when they were paired with a dip, flavour or added energy, with 8 to 10 exposures as the working minimum. — 30 studies, 44 intervention arms, 4017 preschool children aged 2-5 years, published 2005 to January 2016 (n = 4017) Evidence B source
  Repeated taste exposure had better pooled effects; intake greater for plain vegetables than for vegetables paired with a flavour, dip or added energy

Who this works differently for

• In 152 preschoolers, children sensitive to bitter taste ate 80% more raw broccoli when it came with a salad-dressing dip than when served plain over 7 weeks, while the dip made no difference for bitter-insensitive children. — 152 predominantly Hispanic preschoolers in Head Start classrooms, broccoli twice weekly for 7 weeks, classrooms randomised to 4 dip conditions (n = 152) Evidence B source
  Bitter-sensitive: +80% broccoli intake with dressing vs plain (P<0.001); no effect in bitter-insensitive children; liking not changed by dip
• In 24 adults with active Crohn's disease, 4 weeks on a diet high in food-supply emulsifiers versus a low-emulsifier diet gave no difference in disease activity, with clinical remission in 9 of 12 versus 7 of 12. — 24 adults with symptomatic, sonographically active ileal Crohn's disease on stable therapy, Melbourne, double-blind randomised feeding study, 4 weeks (n = 24) Evidence B source
  Remission (HBI < 5) 9/12 on high-emulsifier vs 7/12 on low-emulsifier diet; IBUS-SAS fell on both diets; no statistically significant between-diet differences

The bottom line

The sodium is the part with a number attached, and the number is a category average rather than a label. FDA's voluntary sodium reduction goals, Edition 2, put restaurant salad dressings, a category that explicitly includes ranch dipping sauces, at a 2022 baseline of 845 mg per 100 g, with a target mean of 550 mg and an upper bound of 870 mg. Packaged dressings sit at 762 mg baseline. These are voluntary targets and category means, so any one bottle may sit well above or below them. Across six NHANES cycles from 1999 to 2010, salad dressing was the only food group whose share of US adults' sodium intake rose in four consecutive cycles against 1999-2000, from single 24-hour recalls that give no milligram figure for the dressing itself. The gums and emulsifiers on a bottled ranch label have observational data against them and short, exploratory trial data that finds no difference on the markers it measured. Neither cohort studied ranch itself. In 104 139 French adults followed for a mean 6.8 years, each extra 500 mg a day of xanthan gum was associated with type 2 diabetes at a hazard ratio of 1.08 (95 percent CI 1.02 to 1.14). Guar gum came in at 1.11 (1.06 to 1.17). Additive intake there was estimated from label databases, and these additives travel with ultra-processed foods, so the food pattern may be doing the work. In 95 442 adults of the same cohort over a median 7.4 years, celluloses carried a cardiovascular hazard ratio of 1.05 per standard deviation of intake (1.02 to 1.09), and mono- and diglycerides were associated with higher risk of all outcomes. Set against that, 60 healthy adults randomised to 4 weeks of carboxymethyl cellulose, polysorbate 80, carrageenan or soy lecithin, delivered in brownies rather than in dressing, showed no difference from placebo in faecal calprotectin, C-reactive protein or cholesterol. Carrageenan raised transcellular gut permeability compared with its own baseline. In 24 adults with active ileal Crohn's disease, 4 weeks on a high-emulsifier diet against a low one gave clinical remission in 9 of 12 versus 7 of 12, with no significant difference, in an exploratory trial with 5 withdrawals. We have no card on allergy, pregnancy or medicines for ranch, and the children on this page were studied for how much broccoli they ate, not for safety. A bottled ranch is usually built on buttermilk, and often on egg, and neither milk nor egg allergy has a card here, so the label is the only guide. There is also no USDA composition entry under this name, so the calories and fat of a given bottle are on its label and nowhere on this page. On the fat itself, one more trial. In 16 healthy adults, 28 g of fat served as a lab-made emulsion gave a 40 percent larger 10-hour rise in plasma carotenoids than the same fat unemulsified. Olive oil beat coconut oil by 55 percent for total carotenoids. Ranch is an emulsion, though not that one, and we found no trial of ranch itself or of homemade against bottled.
