Pot pie: salt, size and a microwave warning

We found no trial of pot pie itself, so the strongest evidence here is about the salt in it. A Cochrane meta-analysis of 34 randomized trials in 3,230 people found that eating about 4.4 g less salt a day for at least 4 weeks lowered systolic blood pressure by 4.18 mm Hg (95% CI 3.18 to 5.18). That result is about salt in general, and no pot pie was tested. The US survey database, built from recipe composites, puts chicken pot pie at 375 mg sodium and 255 calories per 3.5 oz (100 g) and beef pot pie at 374 mg sodium and 271 calories. One individual pie is counted as 250 g, two and a half times those figures in a single sitting. Protein is modest, 9.24 g per 3.5 oz (100 g) for chicken and 8.92 g for beef, with 2 g of fiber in both.

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

How much is actually in it

• In the US survey food database, chicken pot pie has 255 calories, 9.24 g protein, 2 g fiber and 375 mg sodium per 3.5 oz (100 g). — Pot pie, chicken, FNDDS food code 27347100 Evidence E source
  Per 100 g: 255 calories, protein 9.24 g, fiber 2 g, sodium 375 mg
• In the US survey food database, beef pot pie has 271 calories, 8.92 g protein, 2 g fiber and 374 mg sodium per 3.5 oz (100 g). — Pot pie, beef, FNDDS food code 27317010 Evidence E source
  Per 100 g: 271 calories, protein 8.92 g, fiber 2 g, sodium 374 mg

What a real portion looks like

• US dietary surveys count one individual pot pie as 250 g, which works out to about 640 to 680 calories and about 935 mg sodium. — Pot pie, chicken and beef, FNDDS 27347100 and 27317010 Evidence E source
  Individual pie 250 g, slice 210 g, cup 200 g, whole pie 1260 g

What cooking and storage change

• Frozen pot pies were linked to a 2007 US Salmonella outbreak of 401 cases in 41 states, and 77% of patients who ate them had cooked them in a microwave. — 401 cases in 41 states, United States, 2007 (n = 401) Evidence C source
  32% hospitalized, case-control odds ratio 23.6
• In the investigation of the same pot pie outbreak, most patients had not followed the cooking instructions and did not know their microwave wattage. — 396 Salmonella I 4,5,12:i:- infections (n = 396) Evidence C source

What it does to your health

• In an inpatient crossover RCT on 20 adults, an ultra-processed diet led people to eat 508 calories a day more than an unprocessed diet over 2 weeks. — 20 weight-stable adults, 2 weeks per diet (n = 20) Evidence B source
  +508 calories/day, weight +2 lb (0.9 kg) vs -2 lb (-0.9 kg)

Safety, limits and interactions

• Observational outbreak data show many frozen meals are not heat-and-serve and must be fully cooked, as a 2010 Salmonella outbreak from a frozen chicken meal sickened 44 people. — 44 ill persons in 18 states, 2010 (n = 44) Evidence C source
  Matched OR 30.7 (95% CI 6.4 to infinity)

Who this works differently for

• By a Cochrane meta-analysis of 34 randomized trials, cutting salt by about 4.4 g a day for at least 4 weeks lowered systolic blood pressure by 4.18 mm Hg, and by 5.39 mm Hg in people with hypertension. — Thirty four trials (3230 participants), at least four weeks (n = 3230) Evidence A source
  SBP -4.18 mm Hg (95% CI -5.18 to -3.18), hypertensive -5.39 (95% CI -6.62 to -4.15)

The bottom line

Frozen pot pies have a documented cooking problem. In a 2007 US outbreak from a single brand, 401 people in 41 states got salmonellosis from pot pies and 32 percent of them were hospitalized. Of the patients who ate the pies, 77 percent had cooked them in a microwave, and investigators said confusion over the microwaving instructions might have left the pies undercooked. A later review of 396 of those infections found that the labels used microwave wattage categories they never defined. Most patients had not followed the cooking instructions and did not know their own oven wattage. Many frozen meals are labeled not ready to eat and need full cooking, because some ingredients may not have been through a step that kills pathogens. That warning comes from a 2010 outbreak in 44 people in 18 states, traced to a frozen chicken and rice meal, and no pie was involved. If the box says the meal is not ready to eat, check your microwave wattage and follow the cooking instructions in full. Pot pie is also a ready made, processed meal. In an inpatient crossover trial on 20 adults, two weeks on an ultra-processed diet led people to eat 508 calories a day more than two weeks on an unprocessed diet, in a small study that did not test pot pies specifically. Our cards cover food poisoning and salt only. We found nothing on allergy, children, pregnancy or medicines for pot pie, so this page cannot tell you who else should be careful with it.
