Chicken pot pie: the sodium in one frozen pie and why the microwave matters

The strongest evidence near this dish concerns salt in general. A network meta-analysis of 34 randomized trials in 37,063 adults found that replacing regular salt with a low-sodium potassium substitute lowered systolic pressure by 4.39 to 4.64 mmHg, with a mortality benefit that rests mostly on one large Chinese trial. A frozen chicken pot pie is a salty food. USDA lists 393 mg of sodium per 3.5 oz (100 g) of the prepared frozen entree, from one legacy record of one commercial pie. At the 250 g the US dietary survey codes for an individual pie, that comes to about 983 mg, 43 percent of the Daily Value, with about 10.9 g of saturated fat, by recalculation rather than measurement. The other thing to know is cooking. In 2007 frozen pot pies sold raw inside caused 401 Salmonella cases in 41 US states, and 32 percent of the sick went to hospital. Of the patients who ate them, 77 percent had cooked the pies in a microwave, a link drawn from interviews in a single outbreak.

The numbers, per 3.5 oz (100 g)

How much is actually in it

• USDA puts a prepared frozen chicken pot pie at 393 mg of sodium, 11.9 g of fat and 4.4 g of saturated fat per 3.5 oz (100 g), from a single legacy record. — USDA SR Legacy record for Chicken pot pie, frozen entree, prepared (n = 1 record) Evidence E source
  Sodium 393 mg per 3.5 oz (100 g) (17% DV), fat 11.85 g (15% DV), saturated fat 4.365 g (22% DV)

What a real portion looks like

• An individual chicken pot pie in the US dietary survey is coded at 250 g, which at USDA composition means about 980 mg of sodium and 11 g of saturated fat. — FNDDS food code 27347100, Pot pie, chicken, portion weights used to code NHANES recalls Evidence E source
  Slice 210 g, individual pie 250 g, cup 200 g, whole pie 1,260 g; an individual pie is about 983 mg sodium (43% DV), 29.6 g fat and 10.9 g saturated fat scaled from the SR Legacy 100 g values

What cooking and storage change

• Frozen chicken pot pies sold raw inside caused a 2007 US Salmonella outbreak of 401 cases in 41 states, and 77% of patients had cooked them in a microwave. — 401 salmonellosis cases in 41 US states in 2007 linked to frozen not-ready-to-eat pot pies (n = 401) Evidence C source
  32% of ill persons hospitalized; 77% of patients who ate the pies microwaved them; confusing microwave instructions may have led to undercooking

What it does to your health

• A network meta-analysis of 34 trials found that swapping regular salt for a low-sodium potassium substitute lowered systolic pressure by about 4.4 to 4.6 mmHg. — 34 randomized controlled trials, 37,063 adults in 15 countries, mean age 62 (n = 37063) Evidence A source
  Systolic BP -4.39 to -4.64 mmHg with moderate-potassium low-sodium substitutes; 7-17 fewer deaths per 1000

What people believe that the data does not support

• In a pilot RCT on 74 low-income adults with type 2 diabetes, 12 home-delivered frozen tailored meals a week for 3 months lowered HbA1c no more than usual care, 0.7 vs 0.6 points. — 74 low-income adults with type 2 diabetes and HbA1c above 8%, Maryland Medicaid, mean age 48 (n = 74) Evidence B source
  HbA1c -0.7 vs -0.6 percentage points at 6 months; food insecurity fell from 53% to 17% with meals vs 48% to 44% with usual care

Who this works differently for

• Observational data link high ultra-processed food intake in adolescents with 63% higher odds of overweight or obesity across 23 studies. — 23 studies, about 155,000 adolescents (n = 155000) Evidence C source
  OR 1.63 (95% CI 1.36-1.95) for overweight or obesity, higher vs lower UPF intake

The bottom line

A frozen meal is a format, and what goes into it decides the result. In a pilot trial of 74 low-income adults with type 2 diabetes, frozen meals designed by dietitians and delivered home lowered HbA1c no more than usual care, 0.7 against 0.6 points at 6 months. Food insecurity fell from 53 to 17 percent with the meals. These were tailored medical meals, and 77 percent of participants completed the pilot. Observational data link high ultra-processed food intake in adolescents with 63 percent higher odds of overweight or obesity (OR 1.63, 95% CI 1.36 to 1.95) across 23 mostly cross-sectional studies. Frozen pot pies count as ultra-processed, but those studies did not look at them separately. We found no measurement of what baking or microwaving does to the nutrients in the filling. Who should be careful. This page has no card on allergy, pregnancy or medicines for chicken pot pie. The safety fact it does have is the Salmonella outbreak above. A frozen pot pie that is raw inside has to reach a safe internal temperature, and confusing microwave instructions may have left those pies undercooked. The salt-substitute trials above tested potassium-based salt, and this page has no card on who should not use it, such as people with kidney disease or on medicines that raise potassium, so that result is not advice to switch.
