Vegetable chips: still chips, and often higher in acrylamide

In a double-blind crossover pilot of 20 adults, baked jicama vegetable chips, used as a low fat, low sodium control, scored far lower on liking, wanting and craving than regular potato chips (p = .011 to .0001). A small 28 g bag of vegetable chips carries about 139 calories and 92 mg of sodium in US survey data, 495 calories per 3.5 oz (100 g), from one generic entry while brands vary widely. The concern specific to them is acrylamide. A systematic review of lab studies says it forms mainly through the Maillard browning reaction and drops with lower temperature and shorter cooking. Germany's first Total Diet Study measured 230 foods and found the highest average acrylamide in vegetable crisps, 1,430 mcg per kg, in pooled samples that hide brand differences. In a lab study of four commercial chip types, sweet potato chips held 2,342 mcg per kg against 524 in potato chips. Simulated digestion released less of it from the vegetable chips, about 60 percent against 71.7 percent, in a model that never measured human absorption.

As people eat it, per 3.5 oz (100 g)

How much is actually in it

• A small 28 g bag of vegetable chips carries about 139 calories and 92 mg sodium in US survey data, 495 calories per 3.5 oz (100 g). — US household measures, FNDDS (n = 1 food code) Evidence E source
  Per 28 g bag: 138.6 calories, 92.1 mg sodium, 2.2 g fiber, 294.6 mg potassium, 1.9 g sugars, 14.8 ug vitamin A RAE; per 3.5 oz (100 g) 495 calories
• Germany's first Total Diet Study found the highest average acrylamide of 230 foods in vegetable crisps, 1430 ug/kg. — 230 foods from the German market, BfR MEAL Study (n = 230 foods) Evidence C source
  Vegetable crisps 1430 ug/kg vs potato pancakes 558 and pan-fried potatoes 450 ug/kg

What a real portion looks like

• In a 12-week RCT of 102 non-obese adults, a daily 50 g snack of potato crisps was partly offset by eating less elsewhere, but only hazelnuts improved diet quality. — 102 non-obese adults, about 1100 kJ/day of hazelnuts (42 g), chocolate (50 g), potato crisps (50 g) or no snack, 12 weeks (n = 102) Evidence B source
  Partial energy compensation similar across snacks; diet quality improved only with hazelnuts

What your body absorbs

• In a lab study, sweet potato chips held 2342 ug/kg acrylamide versus 524 ug/kg in potato chips, though less of it was released in simulated digestion. — commercial potato, sweet potato, beetroot and carrot chips, in vitro digestion and colonic fermentation (n = 4 chip types) Evidence D source
  Acrylamide sweet potato 2342, carrot 1279, beetroot 947, potato 524 ug/kg; bioaccessibility 59.7-60.4% veggie vs 71.7% potato

What cooking and storage change

• In controlled lab frying, soaking slices and lowering pH cut acrylamide in potato and pumpkin chips but worked less well for carrot chips. — fresh potato, carrot and pumpkin slices fried under controlled conditions (n = 3 vegetables) Evidence D source
  Control acrylamide carrot 224, pumpkin 514, potato 3887 ug/kg; soaking and acidifying most effective
• A systematic review of food chemistry studies found acrylamide forms mainly through the Maillard reaction and falls with lower temperature, shorter cooking or less asparagine and sugar. — food chemistry studies on additives and acrylamide formation Evidence D source
  Lower precursors, temperature and time reduce acrylamide; some additives increase it

What it does to your health

• A meta-analysis of 32 publications found dietary acrylamide unrelated to most cancers, with only a borderline link to kidney cancer (RR 1.20). — epidemiological studies of dietary acrylamide, 14 cancer sites (n = 32 publications) Evidence C source
  Kidney cancer RR 1.20 (95% CI 1.00 to 1.45), high vs low intake; other sites null
• Across 14 prospective cohorts, dietary acrylamide showed no link with breast, endometrial or ovarian cancer. — women in 14 prospective cohort studies (n = 14 cohorts) Evidence C source
  Breast RR 0.95 (0.90 to 1.01), endometrial 1.03 (0.89 to 1.19), ovarian 1.02 (0.84 to 1.24)

What people believe that the data does not support

• In three US cohorts of 120,877 adults, each extra daily serving of potato chips was linked with 1.69 lb more weight gain every 4 years, the strongest food association. — 120,877 US women and men, not obese at baseline, followed up to 20 years (n = 120877) Evidence C source
  +1.69 lb per 4 years per daily serving of potato chips vs -0.22 lb for vegetables
• In a double-blind crossover RCT of 20 adults, baked jicama vegetable chips were rated far less liked and craved than regular potato chips. — 20 adults, laboratory sessions with regular, no-fat or no-sodium potato chips and baked jicama chips (n = 20) Evidence B source
  Full-dose potato chips higher on liking, wanting, craving (p = .011 to .0001) vs jicama chips

Who this works differently for

• In 53,870 mother-newborn pairs, the highest maternal acrylamide biomarker quartile was linked with 20% higher odds of small-for-gestational-age babies and 131 g lower birth weight. — 53,870 mother-newborn pairs in 5 studies (n = 53870) Evidence C source
  SGA OR 1.20 (1.08 to 1.33); birth weight -131 g (-204 to -58), highest AA-Hb quartile

The bottom line

For cancer the observational data point mostly to no link. A meta-analysis of 32 publications found dietary acrylamide unrelated to most cancers, with a borderline link to kidney cancer (RR 1.20, 95 percent CI 1.00 to 1.45), and intake came from questionnaires in which chips are one source of many. Across 14 prospective cohorts of women, acrylamide showed no link with breast cancer (RR 0.95, 0.90 to 1.01), endometrial or ovarian cancer. We found no trial of vegetable chips on any health outcome, so the evidence on eating chips comes from potato. In three US cohorts of 120,877 adults, each extra daily serving of potato chips went with 1.69 lb more weight gain every 4 years, the strongest food association in that work. In a 12-week trial of 102 non-obese adults, a daily 50 g snack of potato crisps was partly offset by eating less elsewhere, as were chocolate and hazelnuts, and only the hazelnuts improved diet quality. In home-style lab frying, soaking slices and lowering the pH cut acrylamide in potato and pumpkin chips and worked less well for carrot. The carrot and pumpkin chips fried there held less acrylamide than the commercial vegetable chips surveyed, while the potato control held more. This page has no safety section, because we hold no card on allergy, children or drug interactions for vegetable chips. One finding belongs here anyway. In 53,870 mother and newborn pairs, the quarter of mothers with the highest acrylamide blood marker had 20 percent higher odds of a small-for-gestational-age baby (OR 1.20, 1.08 to 1.33) and babies 131 g lighter. That comes from only 5 studies and a marker that also reflects smoking and every other food.
