Vegetable curry: spices blunt the sugar spike, the cook sets the salt

The firmest curry findings come from single meals in small groups of healthy men. In a randomized crossover trial, 20 healthy Chinese men ate white rice with a curry of seven spices and four base vegetables. Their 3 hour blood glucose response fell by 19 percent at one spice dose and 32 percent at a double dose, against a matched meal. That was one meal, and the authors call any long term effect unestablished. A trial of the same design in 20 young men raised the 3 hour GLP-1 response from 10568 to 13905 pg/ml.min at the higher dose, a gut hormone marker measured after one meal. Salt is set by whoever cooks. UK tables list a ready meal vegetable curry at 200 mg sodium per 3.5 oz (100 g), against 23 mg for a homemade Pakistani recipe and 54 mg for a West Indian one, and homemade recipes may leave out salt added to taste. The US survey gives 388 mg per 3.5 oz (100 g), so a 240 g cup carries about 931 mg sodium and 206 calories, recalculated from the per 3.5 oz (100 g) figure.

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

How much is actually in it

• Homemade vegetable curry made with frozen mixed vegetables provides 90 calories, 6.1 g fat, 2.5 g protein and 25 mg sodium per 3.5 oz (100 g) in the UK composition tables. — UK composition data, homemade recipe Evidence E source
  90 calories, 6.1 g fat, 7.2 g carbohydrate, 1495 ug carotene per 3.5 oz (100 g)
• In UK tables a ready-meal vegetable curry carries 200 mg sodium per 3.5 oz (100 g), against 23 mg and 54 mg for two homemade recipes. — UK composition data, ready meal versus homemade recipes Evidence E source
  Ready meal 94 calories and 200 mg sodium per 3.5 oz (100 g); homemade Pakistani 64 calories and 23 mg; West Indian 60 calories and 54 mg
• Carotene in vegetable curry depends on the recipe: UK tables list 212 ug per 3.5 oz (100 g) for one homemade version and 2479 ug for another. — UK composition data, homemade recipes Evidence E source
  Carotene 212 ug/100 g (Islami, 15-791) to 2479 ug/100 g (Pakistani, 15-792); fiber (NSP) 1.8 to 3.1 g/100 g

What a real portion looks like

• A standard 1 cup serving of vegetable curry in US dietary survey data weighs 8.5 oz (240 g) and supplies about 206 calories and 931 mg sodium. — US dietary survey food code 75440600 Evidence E source
  86 calories and 388 mg sodium per 3.5 oz (100 g); 1 cup = 240 g gives 206 calories and 931 mg sodium
• With a photo atlas in rural Nepal, adults overestimated their vegetable curry portions by 20.8% while underestimating rice and dal. — 95 adults in 48 rural households with a pregnant woman, southern Nepal (n = 95) Evidence C source

• In a randomized crossover trial in 20 men, curry with spices and vegetables cut the 3 h glucose response by 19% and 32% at two spice doses versus a matched meal. — 20 healthy Chinese men, curry with seven spices and four base vegetables eaten with white rice (n = 20) Evidence B source
  3 h postprandial glucose iAUC reduced 19% (dose 1) and 32% (dose 2) versus control
• In a randomized crossover trial in 14 healthy men, one curry meal raised flow-mediated dilation from 5.2% to 6.6% while a spice-free meal lowered it. — 14 healthy male subjects, 180 g curry or spice-free control with 200 g rice (n = 14) Evidence B source
  FMD 5.2 to 6.6% after curry (P = 0.001) versus 5.8 to 5.1% after control; postprandial difference P = 0.002

Safety, limits and interactions

The bottom line

Takeaways are the widest range. Measured sodium in 39 takeaway items from 23 outlets in Reading, UK, ran from 2.3 to 9.4 g per curry dish, and not every curry in that small sample was a vegetable one. Almost half of all the foods tested held more sodium than the menu declared. The vegetables change the rest of the bowl. Carotene in UK homemade recipes runs from 212 mcg per 3.5 oz (100 g) in one version to 2479 mcg in another, depending on which vegetables go in. Spice compounds from curry do reach the blood. In 17 Chinese men, plasma cinnamic acid over 7 hours rose with the spice dose, from 8.4 to 376.1 to 875.7 nM.h at 0, 6 and 12 g of mixed spices, which says nothing about the nutrients in the vegetables. In 14 healthy men, one meal of 6.3 oz (180 g) Japanese curry with rice raised flow-mediated dilation of the artery from 5.2% to 6.6%, while a spice-free meal lowered it from 5.8% to 5.1%. That curry was not necessarily a vegetable one, and the measure is a marker. The long term data are observational. In 2920 Singapore adults with a mean age of 65.5, daily curry eaters had lower odds of mild cognitive impairment or dementia over about 4.5 years than those who rarely ate it (adjusted OR 0.21), with curry frequency self reported. In 4551 Singapore adults aged 55 and over followed for 11.6 years, regular curry eating was linked with lower total mortality, lowest in the middle categories (HR 0.54, 95% CI 0.43 to 0.69). The same authors found more diabetes and central obesity as curry intake rose. Among 7131 Korean women, premenopausal women with high curry intake had 40% lower odds of metabolic syndrome (OR 0.60, 95% CI 0.39 to 0.91) in a cross-sectional survey. None of this shows curry caused the difference. Who should be careful. Spices can carry lead. In North Carolina homes of children with high blood lead, 28.8% of sampled spices and remedies held at least 1 mg/kg lead, and turmeric averaged 66 mg/kg, in homes already linked to poisoning. Across 2235 commercial turmeric samples, 20.4% of those sold as spice were adulterated, which is not always toxic. For tacrolimus, one kidney transplant patient ate 10 g of curry a day for 4 days with no change in drug levels, and one patient cannot settle it. We found no study of vegetable curry in pregnancy or kidney disease. Portions are easy to misjudge. In rural Nepal, 95 adults overestimated their vegetable curry by 20.8% with a photo atlas.
