Burrito: a composite dish the surveys know better than the trials

One trial has actually put a burrito in front of people. Twenty-seven healthy men ate the same burrito-style meal four ways, and against a plant-based meat alternative the grain-fed beef filling gave a plasma triglyceride response 0.346 lower (95% CI 0.692 to 0.0004) and the lamb 0.458 lower (95% CI 0.880 to 0.034). The beef interval stops a whisker short of zero, the authors call the differences subtle, and what was measured is blood over four hours in healthy young men. Everything else known about burritos comes from counting what people eat. Burritos and tacos supply 4.3 percent of all the sodium eaten in the United States, the fifth largest source in the national diet, behind pizza at 5.3 percent, breads at 4.7, cold cuts at 4.6 and soups at 4.4. That figure rests on one 24-hour recall each in 7081 people, it merges burritos with tacos, and it describes a population rather than your lunch. The three USDA records behind this page are frozen and microwaved supermarket burritos, which is not the object a restaurant hands you in foil.

The numbers, per 100 g

How much is actually in it

• After the 2010 school meal standards took effect, school burritos improved in both nutrient adequacy and energy per serving, in middle schools and in high schools alike. — 1.7 million student-selected lunch entrees in three middle schools and three high schools in one urban Washington State district, 16 months before and 15 months after implementation (n = 1.7 million entrees) Evidence C source
  Significant improvement in mean adequacy ratio and energy per serving for burritos in both school levels, with the variety of entrees falling by 44 percent
• Burritos and tacos sit among the top ten sources of beef in the US diet, and six of those ten are mixed dishes rather than cuts of meat. — 10 248 US adults in NHANES 2015 to 2018, 24-hour dietary recalls (n = 10248) Evidence C source
  Six of the top ten beef sources are mixed dishes, burritos and tacos among them, while 12 percent of people eating disproportionate beef diets accounted for half of all beef consumed

What your body absorbs

• In 27 healthy men eating the same burrito-style meal four ways, grain-fed beef and lamb fillings produced a lower post-meal triglyceride response than a plant-based meat alternative. — 27 healthy males, randomised crossover, a standardised burrito-style meal with grain-fed beef, pasture-fed beef, lamb or a plant-based meat alternative matched for protein and carbohydrate, blood hourly for 4 h (n = 27) Evidence B source
  Plasma triglyceride response against the plant-based alternative, grain-fed beef -0.346 (95% CI -0.692 to -0.0004) and lamb -0.458 (95% CI -0.880 to -0.034), with the authors calling the differences subtle

Safety, limits and interactions

• Sixteen outbreaks of sudden gastrointestinal illness in seven states in 1997 and 1998 followed school burrito lunches and affected more than 1900 people, with odds of illness of 2.6 among those who ate them and no agent ever identified. — school children and staff in seven US states, 504 cases in the North Dakota outbreak alone, burritos from two unrelated companies (n = 1900) Evidence C source
  Odds ratio 2.6 (95% CI 1.6 to 4.2) for eating burritos, these are odds rather than risk, median incubation 35 minutes and median illness 6 hours, with nausea in 72 percent
• Burritos and tacos supply 4.3 percent of all the sodium eaten in the United States, the fifth largest single source in the national diet. — 7081 Americans in the 2017-2018 National Health and Nutrition Examination Survey, 24-hour dietary recalls (n = 7081) Evidence C source
  Burritos and tacos 4.3 percent of population sodium intake, behind pizza 5.3 percent, breads 4.7 percent, cold cuts 4.6 percent and soups 4.4 percent, and the ranking held across subgroups
• The FDA asks industry to bring average US sodium intake down to 2,750 mg a day from about 3,400 mg now, by setting targets for food categories including the restaurant and prepared dishes a burrito belongs to. — the US population aged 1 year and older Evidence E source
  Phase II goal of 2,750 mg a day against a current average of about 3,400 mg, through voluntary category targets for manufacturers, restaurants and food service

What people believe that the data does not support

• Among 1235 US meat eaters choosing between a steak, a chicken and a vegetarian burrito, front-of-package warnings changed what people believed but not what they chose. — 1235 US red meat consumers, mean age 44, randomised online to no label, a health warning, an environment warning or both (n = 1235) Evidence B source
  No significant difference in choosing the steak burrito between label conditions, while the health warning raised the share naming it most damaging to health to 73 percent against 63 percent with no label, p < 0.05

Who this works differently for

• Among 3112 US children aged 6 to 11, burritos and tacos were the leading high glycaemic index food for Mexican American children, where other groups had pizza or rice. — 3112 children aged 6 to 11 in NHANES 2011 to 2016, by race and ethnicity (n = 3112) Evidence C source
  Top high glycaemic index food by group: burritos and tacos for Mexican American children, pizza for other Hispanic, White and Black children, rice for Asian American children, with rice alone 37 percent of their high GI foods

The bottom line

Sodium is the number worth carrying out of here. The FDA asks industry to bring average US intake down to 2,750 mg a day from about 3,400 mg now, through voluntary targets for food categories that include the restaurant and prepared dishes a burrito belongs to. That is a population goal aimed at manufacturers rather than a limit for one person, and the category chart is where a given dish gets its number. We found nothing that measures the sodium in a restaurant burrito itself. Among 3112 US children aged 6 to 11, burritos and tacos were the leading high glycaemic index food for Mexican American children, while pizza led for other Hispanic, White and Black children and rice for Asian American children. The glycaemic index there was assigned to a category of mixed dishes rather than measured in those children, and a survey like that describes what groups eat rather than what a food does. In 10 248 adults, burritos and tacos sat among the top ten sources of beef in the US diet, six of which are mixed dishes rather than cuts of meat. That says where beef hides, not how much beef your burrito holds. The hard caution on this page is nearly thirty years old and still unexplained. Sixteen outbreaks of sudden gastrointestinal illness in seven states in 1997 and 1998 followed school burrito lunches supplied by two unrelated companies and affected more than 1900 people. Nothing was ever shown to have been in the food. Eating burritos carried odds of illness of 2.6 (95% CI 1.6 to 4.2), and those are odds rather than risk. Illness came fast, a median 35 minutes, and ran a median 6 hours, with nausea in 72 percent of the 504 cases counted in North Dakota. The agent was never identified. Plant inspections, tracebacks and laboratory work all came back empty, and the investigators argue against mass psychogenic illness rather than proving a toxin. Warning labels moved opinions more than orders. Among 1235 US red meat eaters choosing online between a steak, a chicken and a vegetarian burrito, a health warning raised the share naming the steak burrito most damaging to health to 73 percent against 63 percent with no label (p < 0.05). The share who actually picked it did not differ between label conditions. That was a picture on a screen in a convenience sample, and the authors say real behaviour still has to be tested. School burritos, meanwhile, did change. Across 1.7 million student-selected entrees in six schools of one Washington State district, burritos improved on both mean adequacy ratio and energy per serving after the 2010 school meal standards. That was a before-and-after with no control district, and the variety of entrees offered fell by 44 percent. What is missing is most of a normal page. We found nothing on burritos for pregnancy, for medicines, for kidneys, or for what reheating does to one, and no dataset we hold covers the restaurant version at all.
