Beef salad: what the beef brings and what the raw greens risk

A meta-analysis of 18 randomized trials found that eating more red meat raised blood CRP, a marker of inflammation, by a mean 0.23 (95% CI 0.08 to 0.39). The abstract does not state the unit, and the rise was not seen when the meat was unprocessed or when people had no cardiometabolic disease. The sliced steak in most beef salads is unprocessed red meat. Nobody we could find has studied beef salad as a dish, whether Thai beef salad, larb or steak salad, so this page borrows from research on beef and on raw produce. US survey data put a cup at 182 g and a default serving at 136 g, and they give no recipe split between beef, greens and dressing.

What your body absorbs

• Pooled controlled intervention studies in 397 adults found that eating more red meat raised hemoglobin by about 2.4 g/L, with no significant change in ferritin overall. — 397 adults aged 18-70 (81% women) with normal or suboptimal iron status, 10 studies, 8-52 weeks (n = 397) Evidence C source
  Hb +2.36 g/L (95% CI 0.71-4.02); ferritin +1.87 ug/L (-0.73 to 4.48) overall, +2.27 (0.87-3.67) at 8+ weeks

What cooking and storage change

• USDA factors for broiled beef cuts keep 95% of iron and all of the zinc, but only 60% of vitamin B6 and 70% of thiamin. — USDA group factor for beef products, broiled cut (n = -) Evidence E source

What it does to your health

• A meta-analysis of 18 randomized trials found that eating more red meat raised blood CRP slightly, by a mean 0.23 units, with the rise not seen for unprocessed red meat alone. — adults in 22 RCTs (1152 people) and 10 observational studies (n = 18 RCTs for CRP) Evidence A source
  CRP weighted mean difference 0.23 (95% CI 0.08-0.39); no effect on IL-6, TNF-alpha, leptin, adiponectin
• Observational data from 31 studies link red meat with 13% higher risk of colorectal adenomas, while unprocessed red meat alone showed no significant link. — 31 observational studies of meat intake and colorectal precancerous lesions (n = 31 studies) Evidence C source

• For the beef in a beef salad, USDA FSIS advises 145 °F (63 °C) plus a three-minute rest for steaks and roasts, and 160 °F (71 °C) for ground beef, measured with a food thermometer. — consumers cooking beef, USA Evidence E source
  145 °F plus 3-minute rest for whole cuts; 160 °F for ground beef
• For the fresh vegetables in a salad, FDA advises washing all produce under running water and not using soap or produce wash, which reduces bacteria but will not eliminate them. FDA says to keep lettuce and other perishable produce in a clean refrigerator at 40 F or below and to refrigerate all produce bought pre-cut or packaged. — US consumers preparing fresh fruits and vegetables at home Evidence E source
  Wash greens under running water without soap; refrigerate lettuce and pre-cut or packaged produce at 40 F or below

Who this works differently for

• In a crossover trial in 23 people with past calcium kidney stones, two servings of beef a day gave the same urinary stone risk as the same protein from plants. — 23 normocalciuric adults with a history of calcium stones, 4-day diet plus 2-day metabolic unit (n = 23) Evidence B source
  Tiselius risk index no different between beef and plant protein; both lower than usual diet
• In pooled data on 1162 people with alpha-gal syndrome, a tick-bite allergy to red meat, 92% had symptoms starting 1 hour or more after eating red meat. — 1162 patients with alpha-gal syndrome in 15 studies (57% female) (n = 1162) Evidence C source
  Delayed onset 91.8% (95% CI 84.6-96.8); urticaria 63.8%; any GI symptom 69.2%
• For anyone serving beef salad, CDC names people 65 and older, children under 5, people with weakened immune systems and pregnant women as the groups at higher risk of food poisoning, and children under 5 are three times more likely to be hospitalized if they get a Salmonella infection. — people 65 and older, children under 5, people with weakened immune systems, pregnant women Evidence E source
  Children under 5 three times more likely to be hospitalized with Salmonella infection

The bottom line

Eating more red meat does move blood iron markers a little. Pooled controlled studies in 397 adults found more red meat raised hemoglobin by 2.36 g/L (95% CI 0.71 to 4.02). Ferritin, the iron store, did not change significantly overall (1.87 ug/L, minus 0.73 to 4.48). The authors did not say the studies were randomized, and they call the clinical meaning unclear. Grilling keeps most of the minerals. USDA factors for a broiled beef cut keep 95 percent of the iron and all the zinc, 60 percent of vitamin B6 and 70 percent of thiamin, though those factors date from 1975 and name no doneness. Observational data from 31 studies link red meat intake with 13 percent higher risk of colorectal adenomas (RR 1.13, 95% CI 1.05 to 1.21). Unprocessed red meat on its own showed no significant association, and neither did charred meat. Several cautions apply. Alpha-gal syndrome is a red meat allergy that follows tick bites. In pooled data on 1162 diagnosed patients, 91.8 percent had symptoms starting an hour or more after eating red meat (95% CI 84.6 to 96.8), and hives were the most common sign, at 63.8 percent. People with past calcium kidney stones have one short trial. In 23 of them, two servings of beef a day gave the same urinary stone risk as the same protein from plants over a few days, measured by urine markers only. The raw part of the salad carries its own risk. Across 29 Ethiopian studies of 6659 farm and market samples, 48.76 percent of raw vegetables and fruits were contaminated (95% CI 40.78 to 56.74), and that figure does not describe washed greens sold in high-income countries. FDA advises washing all produce under running water, without soap or produce wash, and says washing can reduce bacteria but will not eliminate them. It advises keeping lettuce and other perishable produce in a clean refrigerator at 40 °F or below. In cattle, about 10.8 percent of deep lymph nodes carry Salmonella (95% CI 7.5 to 14.5), and these nodes end up in ground beef, so the risk applies to salads made with ground beef more than to sliced whole steak. USDA FSIS says ground beef may turn brown before it has reached a temperature at which bacteria are destroyed, and that ground beef cooked to 160 °F (71 °C), measured with a food thermometer, is safe regardless of color. For steaks and roasts it advises 145 °F (63 °C) with at least a three-minute rest. CDC names people 65 and older, children under 5, people with weakened immune systems and pregnant women as the groups at higher risk of food poisoning, and children under 5 are three times more likely to be hospitalized if they get a Salmonella infection. We have no card on medicines for this dish.
