Pasta sauce: the lycopene arrives, the heart markers did not move

Pooling 34 randomized trials in adults, lycopene and tomato intake did not change blood lipids, blood pressure, fasting glucose, CRP or body weight. The one shift was a fall in the oxidative stress marker MDA, and the abstract does not give its size. The EU also refused a health claim for lycopene from tomato pulp and sauces, which means the evidence fell short when it was assessed. What a jar reliably delivers is salt. A typical US spaghetti sauce has 419 mg sodium per 3.5 oz (100 g), and a 260 g cup, recalculated from that figure, carries about 1089 mg. That is close to half of the 2300 mg a day the Dietary Guidelines set for people 14 and older, while average US intake is already about 3400 mg.

The numbers, per 3.5 oz (100 g)

What your body absorbs

• Across 12 RCTs, eating carotenoid-rich foods with more fat raised carotenoid absorption, and unsaturated fats worked about three times better than saturated fats (SMD 0.90 vs 0.27). — 27 in vitro studies and 12 RCTs of carotenoid-rich foods with added dietary fat (n = 12 RCTs) Evidence A source
  Unsaturated fat SMD 0.90 (95% CI 0.69-1.11) vs saturated fat SMD 0.27 (95% CI 0.08-0.47)
• In 16 adults, a carotenoid-rich meal with olive oil gave 45.8 percent more lycopene absorption over 10 hours than the same meal with coconut oil. — 16 subjects, identical salad with 0.99 oz (28 g) of one of 4 fats, randomized crossover (n = 16) Evidence B source
  Lycopene positive iAUC1-10h +45.8% with olive oil vs coconut oil; emulsified fat +40.0% total carotenoids

What cooking and storage change

• In a crossover trial tracking 11 urinary and 4 plasma tomato phenolic metabolites, turning raw tomatoes into sauce raised naringenin glucuronide more than adding olive oil did. — healthy adults, acute intake of raw tomatoes vs tomato sauce with or without refined olive oil, randomized crossover (n = -) Evidence B source
  Naringenin glucuronide plasma and urinary excretion significantly higher after sauce than raw tomatoes
• In 40 healthy adults a single serving of tomato sauce made with olive oil moved several inflammation markers more than raw tomato or plain sauce within 6 hours. — 40 healthy subjects, single doses of 7.0 g raw tomato/kg, 3.5 g tomato sauce/kg or 3.5 g sauce with refined olive oil/kg, crossover (n = 40) Evidence B source
  Greater changes in IL-6, VCAM-1, LFA-1 and CD36 after sauce with olive oil vs raw tomato and plain sauce at 6 h

Safety, limits and interactions

• A mold-allergic patient had repeated anaphylaxis from yeast extract used as flavoring in two pasta sauces, so yeast is a possible hidden allergen in ready-made sauces. — one mold-sensitized adult patient (n = 1) Evidence D source
  Positive skin prick and IgE tests to both pasta sauces and the yeast ingredient
• Average US sodium intake is about 3400 mg a day, and the Dietary Guidelines advise people 14 and older to stay under 2300 mg. — US population aged 14 years and older (n = -) Evidence E source
  Limit 2300 mg/day vs average intake about 3400 mg/day

What people believe that the data does not support

• Pooling 34 RCTs, lycopene and tomato intake did not change blood lipids, blood pressure, glucose or body weight in adults, and only lowered the oxidative marker MDA. — adults in 34 RCTs of lycopene or tomato consumption (n = 34 RCTs) Evidence A source
  No significant effect on TG, TC, LDL-C, HDL-C, FBG, SBP, DBP, CRP, body weight, BMI; significant MDA reduction
• The EU refused a health claim that lycopene from tomato pulp and sauces should be eaten for its nutritional qualities. — EU Register on nutrition and health claims (n = -) Evidence E source

Who this works differently for

• In 33 men awaiting prostate surgery, 5-7 oz (142-198 g) of tomato sauce a day raised plasma lycopene by 71 percent and left prostate lycopene 3.6 times higher than in controls. — 33 men scheduled for prostatectomy, randomized to lycopene-restricted diet, tomato soup, tomato sauce or vegetable juice (25-35 mg lycopene/d) (n = 33) Evidence B source
  Plasma lycopene 0.48 to 0.82 umol/l (+71%) with sauce; prostate lycopene 3.6-fold vs control (P=0.001)
• In 79 adults with fatty liver, 200 g raw tomatoes plus 50 g tomato sauce a day for 6 weeks cut liver fat (CAP) by 26.6 dB/m more than a tomato-free diet. — 79 adults with MASLD (BMI 30 or less), 42 tomato group vs 37 tomato-free control, 6 weeks (n = 79) Evidence B source
  Treatment-by-time CAP beta -26.63 dB/m (95% CI -44.00 to -9.25)
• In 98 adults with fatty liver, a patented tomato sauce product lowered liver fat (CAP) by 33 dB/m over 12 weeks vs 12 dB/m with a commercial sauce, with larger drops in men and people 60 or older. — 98 patients with MASLD, double-blind, OsteoCol tomato sauce vs commercial tomato sauce placebo, 12 weeks (n = 98) Evidence B source
  CAP -33 +/- 44 dB/m vs -12 +/- 38 dB/m, p=0.014

What is still unknown

• Lab digestion models found that more fat raised carotenoid release from food for every carotenoid tested except lycopene, the main pigment of tomato sauce. — 27 in vitro digestion studies (n = 27 in vitro studies) Evidence D source
  Positive association with fat concentration for carotenoids other than lycopene
• The largest cohort meta-analysis on tomatoes and cancer excluded the only study of tomato sauce itself, so no pooled cancer estimate exists for sauce. — 121 prospective studies screened for tomato, lycopene and cancer (n = 121) Evidence C source
  Tomato sauce study excluded from pooled analysis

The bottom line

Recipes differ. UK food tables give a tomato napoletana sauce 65 calories and 290 mg sodium per 3.5 oz (100 g), and a four cheese sauce 129 calories, 9.7 g fat and 325 mg sodium. USDA lists a reduced sodium spaghetti sauce as a separate item, and brands vary. Fat helps with the other carotenoids in tomato. Across 12 randomized trials, carotenoid-rich foods eaten with more fat were absorbed better, and fats rich in unsaturated fatty acids helped more than saturated ones (SMD 0.90, 95% CI 0.69 to 1.11, against 0.27, 95% CI 0.08 to 0.47). That meta-analysis did not study sauce as its own food. Its lab digestion models found more fat raised release for every carotenoid tested except lycopene, so for the main pigment of tomato sauce the question is open. In 16 people eating one salad with 28 g of fat, olive oil gave 45.8 percent more lycopene absorption over 10 hours than coconut oil. Cooking tomatoes into sauce changes what reaches the blood. In a crossover trial in healthy adults, whose size the abstract does not state, naringenin glucuronide in plasma and urine was higher after tomato sauce than after raw tomatoes. In 40 healthy adults, one serving of sauce made with refined olive oil shifted IL-6, VCAM-1, LFA-1 and CD36 more than raw tomato or plain sauce within 6 hours. These are single-meal changes in surrogate markers. In 33 men awaiting prostate surgery, 5 to 7 oz (142 to 198 g) of tomato sauce a day raised plasma lycopene by 71 percent and left prostate lycopene 3.6 times higher than in controls. That shows the pigment gets there. It says nothing about cancer, and the largest cohort meta-analysis of tomatoes and cancer excluded the one study of sauce itself, so no pooled cancer estimate for sauce exists. Two trials in adults with fatty liver (MASLD) found less liver fat. In 79 adults, 200 g raw tomato plus 50 g sauce a day for 6 weeks cut the CAP score by 26.6 dB/m more than a tomato-free diet (95% CI 9.3 to 44.0), in an unblinded trial where sauce was a fifth of the tomato. In 98 adults, a patented tomato sauce product lowered CAP by 33 dB/m over 12 weeks, against 12 dB/m on an ordinary commercial sauce used as the placebo. Sodium is the main caution for most people. There is also one case report of a mold-allergic adult with repeated anaphylaxis from yeast extract used as flavoring in two ready-made pasta sauces, confirmed by skin and IgE tests. It is a single patient, but if you react to molds, yeast extract on the label is worth noticing. We found nothing on pasta sauce in children, pregnancy or alongside medicines.

The plasma concentration and urinary excretion of naringenin glucuronide were both significantly higher after the consumption of tomato sauce than raw tomatoes. The results suggest that the mechanical and thermal treatments during tomato sauce manufacture may help to deliver these potentially bioactive phenolics from the food matrix more effectively than the addition of an oil component, thus increasing their bioavailability.
