Chicken vs tofu: calories compared

Can tofu replace chicken as a meal's protein? Yes. Per ounce, roasted chicken breast has about 1.8 times the protein of firm tofu, so plan on about 7 oz (200 g) of tofu to match 4 oz (113 g) of chicken. In 9 resistance-training trials, strength and lean mass rose as much on soy protein as on other proteins.

In a meta-analysis, about 25 g of soy protein a day in place of other proteins lowered LDL cholesterol by 4.76 mg/dL (0.12 mmol/L) over a median 6 weeks. That is about 5.1 oz (145 g) of this tofu. A trial of the tofu product Kori-tofu found no significant effect against control.

Cook chicken to 165 °F (74 °C) on a food thermometer and do not wash it raw: USDA says rinsing spreads bacteria to other foods, utensils and surfaces. In Italian data, Campylobacter was on 62 percent of chicken skin samples. Soy is one of the nine major US food allergens. Across 18 trials, soy supplements left thyroid hormones unchanged and raised TSH only slightly. The levothyroxine label says soybean flour may lower the drug's absorption. It does not name tofu, so ask your prescriber. The label for the selegiline patch EMSAM at 9 mg/24 h or more lists tofu among soybean products to avoid.

Choose by taste, and serve more tofu.

How you cook tofu changes its calories more than the choice between these two foods. In UK composition data, frying steamed tofu took it from 73 to 261 calories and from 4.2 to 17.7 g of fat per 3.5 oz (100 g). The tofu in this table is raw, so if yours is fried, expect far more calories than shown here.

Evidence behind this note

1. Level A Across 9 trials with 266 people doing resistance training, soy protein built strength and lean mass as well as whey, beef or milk protein. Int J Sport Nutr Exerc Metab, 2018
2. Level A Across 41 trials, about 25 g soy protein a day for a median 6 weeks lowered LDL cholesterol by 4.76 mg/dL against other proteins. J Nutr, 2019
3. Level B The one trial that fed people tofu itself found its cholesterol improvements happened in the control group too. Nutrients, 2022
4. Level E USDA FSIS advises cooking whole and ground chicken and other poultry to a safe minimum internal temperature of 165 °F (74 °C), measured with a food thermometer. USDA FSIS, Doneness Versus Safety
5. Level E The agency responsible for US poultry safety tells people not to wash raw chicken, because rinsing spreads the bacteria instead of removing them. Chicken from Farm to Table, USDA Food Safety and Inspection Service
6. Level C Italian data from 48 studies found Campylobacter on 62% of chicken skin samples and 20% of meat samples. Vet Med Sci, 2026
7. Level E FDA lists soybeans among the nine major food allergens in the United States, together with milk, eggs, fish, crustacean shellfish, tree nuts, peanuts, wheat and sesame. US FDA, Food Allergies
8. Level A Across 18 RCTs, soy did not change thyroid hormones and raised TSH by only 0.25 mIU/L. Sci Rep, 2019
9. Level E The FDA label for levothyroxine says soybean flour may bind the drug and cut its absorption from the gut. Tofu is a soy food but the label does not name it. Levothyroxine sodium tablets, FDA-approved label, section 7.9, effective 2026-03-24
10. Level E The FDA label for transdermal selegiline (EMSAM) at 9 mg/24 h or more names tofu among the soybean products to avoid because of tyramine. EMSAM (selegiline transdermal system), FDA-approved label, sections 2.3 and 7.2 (Table 5)
11. Level E Frying steamed tofu takes it from 73 to 261 calories and from 4.2 to 17.7 g fat per 3.5 oz (100 g) in UK data. CoFID 2021, Public Health England
