Meat in tomato sauce: the lycopene wants fat, the meat brings its own questions

A meta-analysis of 12 randomized trials found that carotenoids, the pigment family that includes the lycopene in tomato, were absorbed better when eaten with more fat. Unsaturated fats helped more (SMD 0.90, 95% CI 0.69 to 1.11) than saturated fats (SMD 0.27, 95% CI 0.08 to 0.47). That matters for this dish because it brings both the tomato and the fat. Per 100 g, the single averaged recipe in the US dietary survey gives 149 calories, 21.72 g of protein, 6.36 g of fat of which 2.39 g saturated, 355 mg of sodium and 3941 mcg of lycopene. Real versions differ in the meat, the fat and the salt. A cup weighs 8.8 oz (249 g), which by the same survey works out to 371 calories, 54.1 g of protein, 884 mg of sodium and about 9.8 mg of lycopene, recalculated from the 100 g values. In a meta-analysis of 18 randomized trials, eating more red meat raised the inflammation marker CRP by a weighted mean difference of 0.23 (95% CI 0.08 to 0.39), for mixed or unspecified red meat rather than unprocessed cuts alone. A cup also carries 884 mg of sodium, which matters for anyone told to limit salt.

The bottom line

What changes how much lycopene you get. In 16 people eating a single carotenoid-rich salad with 28 g of fat, lycopene uptake was 45.8% higher with olive oil than with coconut oil, and the test meal was a salad. In 12 healthy adults given 5.3 oz (150 g) of sauces made specially for the study, the sauce rich in cis forms of lycopene gave a higher dose-adjusted blood response, 7.30 against 4.74 nmol·h/l (P = 0.002). In 10 healthy adults, adding a 500 mg calcium carbonate supplement to a meal with 19 mg of lycopene from tomato paste cut lycopene bioavailability by 83%, and we found no trial testing cheese the same way. In 33 men due for prostate surgery, tomato sauce raised plasma lycopene from 0.48 to 0.82 µmol/l, a 71% rise, over a period the abstract does not state. The meat side works the other way round for minerals. A scoping review of 77 articles, without pooled numbers, found that adding meat to a single plant-based meal steadily raised iron and zinc absorption, and the effect across a whole diet is less clear. In a meta-analysis of 397 adults, 81% of them women, eating more red meat for 8 to 52 weeks raised hemoglobin by 2.36 g/L (95% CI 0.71 to 4.02), though not every included study was randomized and what that rise means clinically is unknown. Ferritin, the iron store marker, rose by 1.87 mcg/L, a change that did not reach significance (95% CI -0.73 to 4.48). Who should take care. The cautions we hold for this dish are about red meat and cancer markers, all from observational data that show association and cannot show cause. Across 31 observational studies, red meat intake was linked with a 13% higher risk of colorectal adenomas (RR 1.13, 95% CI 1.05 to 1.21), which are precancerous growths rather than cancer. Across 19 cohorts with 4.29 million people, the highest total red meat intake was linked with a 12% higher risk of pancreatic cancer (HR 1.12, 95% CI 1.01 to 1.24). For unprocessed red meat alone the estimate of 1.05 crossed no effect (0.88 to 1.24). We have no card on allergy, pregnancy, children or drug interactions for this dish, so this page says nothing about them either way. What remains unknown is whether tomato sauce itself does anything for cancer risk. Across 121 prospective studies, high lycopene intake was associated with 5% lower overall cancer risk (RR 0.95, 95% CI 0.92 to 0.98) and high blood lycopene with 11% lower risk (RR 0.89, 0.84 to 0.95), for lycopene from any source. The one study on tomato sauce itself was left out of that pooling. The EU refused the claim that lycopene keeps the heart and arteries healthy, and a claim promoting lycopene from tomato pulp and sauces, and the register gives no reason for either.

   The meta-analysis of RCTs showed that the bioavailability of carotenoids was enhanced when a higher quantity of dietary fats was co-consumed.
