General Tso vs orange chicken: the portion decides the salt

The firmest evidence behind these two takeout dishes is about salt. Across 34 randomized trials in 3,230 adults, cutting salt by about 4.4 g a day for at least four weeks lowered systolic blood pressure by 4.2 mmHg. Per 100 g the two dishes sit close together in the US food survey database: General Tso chicken has 295 calories and 435 mg of sodium, orange chicken 262 calories and 553 mg. The survey cup is where they split. A 146 g cup of General Tso chicken carries about 635 mg of sodium and 431 calories, while a 252 g cup of orange chicken carries about 1,394 mg and 660 calories. Both are single standard recipes scaled to a survey measure, not weighed restaurant orders, and the spread between restaurants is likely wider than the gap between the dishes. Order by the amount on your plate more than by the name on the menu.

How much is actually in it

• Per 100 g, General Tso chicken in the US food survey database is fattier and slightly richer than orange chicken: 295 against 262 calories and 16.4 against 12.7 g of fat, with less sugar (11.6 against 13.6 g) and less sodium (435 against 553 mg). — USDA FNDDS records General Tso chicken (27445150, FDC 2706794) and Orange chicken (27146350, FDC 2706443) (n = 2 records) Evidence E source
  General Tso vs orange chicken per 3.5 oz (100 g): energy 295 vs 262 calories; fat 16.36 vs 12.68 g; total sugars 11.6 vs 13.6 g; carbohydrate 23.99 vs 22.46 g; protein 12.9 vs 14.46 g; sodium 435 vs 553 mg

What a real portion looks like

• The survey cup differs between the dishes: a 146 g cup of General Tso chicken carries about 635 mg of sodium and 431 calories, while a 252 g cup of orange chicken carries about 1,394 mg of sodium and 660 calories. — USDA FNDDS portion weights, 1 cup = 146 g for General Tso chicken and 252 g for orange chicken (n = 2 records) Evidence E source
  Per cup, General Tso vs orange chicken: sodium 635.1 vs 1393.6 mg; energy 430.7 vs 660.2 calories; total sugars 16.9 vs 34.3 g; fat 23.9 vs 32.0 g

What it does to your health

• Across 34 randomized trials in 3,230 people, cutting salt by about 4.4 g a day for at least four weeks lowered systolic blood pressure by 4.2 mmHg. — 3,230 adults in 34 randomized trials of modest salt reduction lasting at least four weeks, with and without hypertension (n = 3230) Evidence A source

• In randomized trials of adults eating freely, cutting dietary sugars lowered body weight by 1.8 lb (0.8 kg) and adding sugars raised it by a similar 1.7 lb (0.75 kg). — Adults in randomized trials with ad libitum diets Evidence A source
  Reduced sugars -1.8 lb (95% CI 0.86 to 2.7; metric: -0.80 kg, 0.39 to 1.21); increased sugars +1.7 lb (0.66 to 2.6; metric: 0.75 kg, 0.30 to 1.19); isoenergetic exchange 0.09 lb (-0.09 to 0.29; metric: 0.04 kg, -0.04 to 0.13)
• Observational data link frequent fried food to gastric cancer: across 18 case-control studies, people eating more fried food had 1.52 times the odds of the disease. — 5,739 gastric cancer patients and 70,933 controls in 18 case-control studies (n = 76672) Evidence C source
  OR 1.52 (95% CI 1.23 to 1.87), I2 76%

Safety, limits and interactions

• FDA's 2024 draft Phase II targets for restaurant and packaged foods aim to bring average US sodium intake down to about 2,750 mg a day, about 20% below intake before the 2021 targets. — US commercially processed, packaged and restaurant-prepared foods Evidence E source
  Target average intake about 2,750 mg/day, approximately 20% lower than intake before the Phase 1 targets

What people believe that the data does not support

• In a double-blind randomized challenge of 61 people who believed they reacted to MSG, symptoms followed a 5 g dose in 36.1% against 24.6% after placebo, a difference that was not significant. — 61 self-identified MSG-sensitive adults, oral challenge with 5 g MSG or placebo, rechallenge at 1.25 to 5 g (n = 61) Evidence B source
  Responders 36.1% MSG vs 24.6% placebo (p = 0.324); symptom severity higher after MSG; apparent threshold 2.5 g
• In a randomized double-blind crossover trial of 71 healthy people given up to 3.15 g of MSG before breakfast over 5 days, 85% had no reaction to MSG and 86% none to placebo. — 71 healthy subjects, MSG 1.5, 3.0 and 3.15 g or placebo before a standardized breakfast over 5 days (n = 71) Evidence B source
  No response 85% after MSG vs 86% after placebo; sensations attributed to MSG no more frequent than after placebo

Who this works differently for

• A Cochrane review found only two crossover trials in 24 adults with chronic asthma and no difference between MSG and placebo in lung function falls, with no trials at all in children. — 24 adults with chronic asthma in two crossover RCTs, MSG challenge doses 1 g, 5 g and 25 mg/kg (n = 24) Evidence A source
  No statistically significant difference in the number with FEV1 fall above 15% or 6.8 fl oz (200 mL) after MSG versus placebo

The bottom line

Sugar is the other difference. A survey cup holds 16.9 g of sugars for General Tso chicken and 34.3 g for orange chicken. In a meta-analysis of randomized trials in adults eating freely, cutting sugars lowered body weight by 1.8 lb (95% CI 0.86 to 2.7; metric: 0.8 kg, 0.39 to 1.21), and trading sugar for other carbohydrate at the same calories changed nothing. Both dishes are battered and deep fried. Across 18 case-control studies, people who ate more fried food of any kind had 1.52 times the odds of gastric cancer (95% CI 1.23 to 1.87). That is an association built on recall, with high heterogeneity between studies, and it cannot show that the frying caused anything. The MSG worry has been tested and mostly does not hold. In a double-blind crossover trial of 71 healthy people given up to 3.15 g of MSG before breakfast, 85% had no reaction to MSG and 86% none to placebo. In 61 people sure they reacted to MSG, a 5 g dose taken on its own, without food, was followed by symptoms in 36.1% against 24.6% after placebo, and that gap did not reach significance. For adults with chronic asthma a Cochrane review found only two small crossover trials in 24 people, with no difference in lung function falls between MSG and placebo. On who should be careful, we have no card on allergy, pregnancy, children or medicines for these dishes. What we do have is scale. FDA’s voluntary 2024 draft targets aim to bring average US sodium intake to about 2,750 mg a day. That is a goal for the population average, not a safe amount for one person, and one survey cup of orange chicken is about half of it before rice or soy sauce.
