Burrito bowl: what the beans do and what the bowl costs in salt

We found no study of the burrito bowl as a dish, so the evidence here is about its base. In a randomized crossover trial on 12 healthy women, black beans with white rice kept blood glucose lower at 60, 90 and 120 minutes than the same 50 g of carbohydrate from rice alone. In 17 adults with type 2 diabetes, pinto or black beans with rice gave a lower glucose area than rice alone, while kidney beans with rice were not significantly lower. Both were single breakfasts of plain beans and rice, without the fat, meat and salsa of a restaurant bowl. A typical bowl in US survey data weighs 9.5 oz (270 g) and carries about 392 calories and 840 mg sodium. That is a recipe estimate, and chain bowls with cheese, sour cream and guacamole run higher.

What a real portion looks like

• A typical burrito bowl in US survey data weighs 9.5 oz (270 g) and carries about 392 calories and 840 mg sodium. — US household measures, FNDDS (n = 1 food code) Evidence E source
  Per 100 g: energy 145 calories, sodium 311 mg; per item 270 g: 391.5 calories, 839.7 mg sodium; per cup 120 g: 174.0 calories, 373.2 mg sodium
• Across ten US burrito bowl entries, one bowl ranges from about 290 calories with beans only to 539 calories with beef or pork, beans and rice, and from 666 to 980 mg sodium. — US household measures, FNDDS (n = 10 food codes) Evidence E source
  Energy 129 to 213 calories per 3.5 oz (100 g); per item 290.2 calories (with beans, 225 g) to 538.6 calories (beef or pork, beans and rice, 315 g); sodium per item 666.0 mg (with beans) to 979.6 mg (chicken, beans and rice)

What your body absorbs

• Two ounce-equivalents of black beans delivered 3.02 g essential amino acids against 7.36 g from pork, with lower blood availability in both young and older adults. — two crossover RCTs, 30 young adults (mean 26 y) and 25 older adults (mean 64 y), standardized meal with two oz-eq of pork, eggs, black beans or almonds (n = 55) Evidence B source
  Pork 7.36 g and eggs 5.38 g EAA gave greater postprandial EAA bioavailability than black beans 3.02 g and almonds 1.85 g (p < 0.0001); age did not change the result
• In 20 adults, lysine and threonine uptake from black bean protein did not differ between people aged about 22 and about 73, unlike sorghum, which was 19% lower in the older group. — 10 young (21.8 y) and 10 older (72.8 y) adults, 20 g labeled protein from milk, sorghum or black beans, randomized crossover, dual tracer (n = 20) Evidence B source
  Isotope plasma-to-meal ratio 19% lower in older adults for sorghum (P = 0.041); no difference for black beans (P = 0.849) or milk (P = 0.277)

What it does to your health

• In 12 healthy women, black beans with white rice kept blood glucose lower at 60, 90 and 120 minutes than the same 50 g of carbohydrate from rice alone. — 12 healthy adult women aged 18 to 65, randomized crossover, three breakfast meals each with 50 g available carbohydrate (n = 12) Evidence B source
  Glucose incremental area under the curve differed by treatment (p = 0.027); black bean meal lower than rice at 60 min (p = 0.026), 90 min (p = 0.001) and 120 min (p = 0.024)
• In 17 adults with type 2 diabetes, pinto or black beans with rice gave a lower glucose area than rice alone at 50 g carbohydrate, while kidney beans with rice did not. — 17 men and women aged 35 to 70 with type 2 diabetes (14 on metformin), randomized 4 x 4 crossover, breakfast after a 12 hour fast (n = 17) Evidence B source
  Net glucose lower for all three bean and rice meals at 90, 120 and 150 min; incremental area lower for pinto and black bean meals, not for kidney beans
• In 35 older adults, a tortilla breakfast with 135 g black or kidney beans did not differ from one with 80 g beef in appetite ratings or later intake. — 35 older adults, mean age 72.4, BMI 25.1, randomized crossover, three breakfast tortilla meals (n = 35) Evidence B source
  Appetite areas under the curve, ad libitum pizza intake and 24 h energy intake did not differ between bean and beef meals

Safety, limits and interactions

• Table salsas in Mexican restaurants were often contaminated: 47 of 71 in Guadalajara and 10 of 25 in Houston carried E. coli. — 96 tabletop sauces from Mexican-style restaurants in Guadalajara and Houston, summer 1998 (n = 96) Evidence C source
  E. coli in 66% of Guadalajara vs 40% of Houston sauces (P = 0.03); enteroaggregative E. coli in 14 of 32 Guadalajara sauces tested
• A 1996 Georgia salmonella outbreak was tied to eating at one Mexican restaurant, with a relative risk of 13. — matched case-control study of Salmonella Enteritidis cases in Waycross, Georgia, May 1996 Evidence C source
  Relative risk 13 (95% CI 3 to 62) for eating at Restaurant A; suboptimal storage and cooking temperatures found

What people believe that the data does not support

• Fast-casual chain entrees, the kind of restaurant that sells burrito bowls, averaged 760 calories against 561 calories at fast-food chains, despite being seen as healthier. — 3193 lunch and dinner entrees from 34 fast-food and 28 fast-casual US chains, MenuStat 2014 (n = 3193) Evidence C source
  760 plus or minus 301 calories vs 561 plus or minus 268 calories per entree, P < 0.0001

The bottom line

The ten US survey entries for a burrito bowl span about 290 calories for beans only in a 7.9 oz (225 g) bowl to 539 calories for beef or pork with beans and rice in a 11 oz (315 g) bowl, and 666 to 980 mg sodium. Part of that spread is simply bowl weight. Per portion, beans give less usable protein than meat. In two crossover trials in 55 young and older adults, two ounce-equivalents of black beans delivered 3.02 g of essential amino acids against 7.36 g from pork, with lower availability in the blood. The portions were matched by US ounce-equivalent, so the protein in them differed. A dual tracer study on 20 adults found no significant difference in lysine and threonine uptake from black bean protein between people around 22 and around 73. For fullness, 35 older adults rated a tortilla breakfast with 135 g black or kidney beans no differently from one with 80 g beef, and ate no differently later that day. That is a null result over one day and does not prove the two meals equal. Fast-casual chains have a healthier image, and their menus do not bear it out. In 2014 menu data on 3193 entrees, fast-casual chains averaged 760 calories per entree against 561 at fast-food chains. Those figures cover every entree listed, so bowls in particular and what people actually bought were not measured. Who should be careful. The food safety cards are about Mexican-style restaurants in general. In 1998, 47 of 71 tabletop sauces in Guadalajara and 10 of 25 in Houston carried E. coli. A 1996 salmonella outbreak in Georgia was tied to eating at one Mexican restaurant with a relative risk of 13 (95% CI 3 to 62). It was one outbreak at one restaurant, not a study of bowls. We have no card on allergy, pregnancy or medicines for this dish.
