Beef Wellington: a rich dish judged on the beef evidence

We found no study of Beef Wellington as a dish, so the health evidence here is about red meat and beef. The firmest finding comes from a meta-analysis of 36 randomized trials with 1803 people: red meat lowered total cholesterol 10 mg/dL (0.264 mmol/L) less than diets built on legumes, soy or nuts, and against all control diets taken together there was no difference. A second meta-analysis pooled 18 randomized trials and found more red meat raised C-reactive protein, a blood marker of inflammation, by a weighted mean difference of 0.23 (95% CI 0.08 to 0.39). That effect did not hold for unprocessed red meat alone, which is what the fillet in a Wellington is. The dish itself is dense. One homemade UK recipe gives 356 calories, 25.5 g fat and 10.19 g saturated fat per 3.5 oz (100 g), and US survey data code a slice at 116 g, about 427 calories when worked out from the 100 g values.

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

How much is actually in it

• The UK composition table gives homemade Beef Wellington 356 calories, 16.3 g protein, 25.5 g fat and 16.2 g carbohydrate per 3.5 oz (100 g). — CoFID 2021, food code 19-552, Beef Wellington, homemade (n = 1 record) Evidence E source
  356 calories, protein 16.3 g, fat 25.5 g, saturated fat 10.19 g, carbohydrate 16.2 g, sodium 297 mg, iron 2.41 mg, zinc 2.6 mg, vitamin B12 1.9 ug per 3.5 oz (100 g)

What a real portion looks like

• One slice of Beef Wellington is coded at 116 g in US survey data, which works out to about 427 calories and 211 mg sodium. — USDA FNDDS, Beef wellington, food code 27214300, fdc_id 2706501 (n = 2 measures) Evidence E source
  1 slice 116 g = 426.9 calories, 211 mg sodium; quantity not specified 87 g = 320 calories; per 3.5 oz (100 g) 368 calories, 182 mg sodium

What your body absorbs

• In an 8-week RCT in 52 iron-deficient women, taking iron with 4 oz (113 g) of beef raised hemoglobin no more than taking it with a plant-based meat substitute. — 52 nonpregnant women of reproductive age with serum ferritin under 25 ug/L, 8 weeks (n = 52) Evidence B source
  Hemoglobin +0.5 g/dL over 8 weeks in both arms, treatment-by-time interaction P > 0.05

What cooking and storage change

• Roasting beef keeps all its iron and zinc in USDA tables but only about half its vitamin B6 and thiamin and 70% of its vitamin B12. — USDA Table of Nutrient Retention Factors Release 6, Beef Products, BEEF, ROASTED (code 601) Evidence E source
  Retained: iron 100%, zinc 100%, riboflavin 95%, niacin 75%, vitamin B12 70%, thiamin 55%, vitamin B6 50%

What it does to your health

• By a meta-analysis of 18 RCTs, eating more red meat raised blood C-reactive protein in adults, with a weighted mean difference of 0.23. — adults with any health status, 22 RCTs (1152 adults), CRP pooled across 18 RCTs (n = 1152) Evidence A source
  CRP weighted mean difference 0.23 (95% CI 0.08 to 0.39), seen at 0.5 servings/day or more, not for unprocessed red meat alone
• By a meta-analysis of 36 RCTs, red meat lowered total cholesterol 10 mg/dL (0.264 mmol/L) less than plant protein diets did. — 36 randomized trials, 1803 participants (n = 1803) Evidence A source
  Vs legumes, soy, nuts: total cholesterol WMD 10 mg/dL (95% CI 5.6 to 15; metric: 0.264 mmol/L, 0.144 to 0.383), LDL WMD 7.7 mg/dL (95% CI 2.5 to 13; metric: 0.198 mmol/L, 0.065 to 0.330)
• Across 10 intervention studies in 397 adults, adding red meat for at least 4 weeks raised hemoglobin by 2.36 g/L. — adults 18 to 70 years, 10 studies, 397 participants, interventions of 4 weeks or more (n = 397) Evidence B source
  Hemoglobin RMCD 2.36 g/L (95% CI 0.71 to 4.02); serum ferritin 1.87 ug/L (95% CI -0.73 to 4.48), not significant overall

Safety, limits and interactions

• Observational data on 1162 people with alpha-gal syndrome show that 91.8% first react an hour or more after eating red meat. — 15 studies, 1162 patients with alpha-gal syndrome, 57% female (n = 1162) Evidence C source
  Symptom onset 1 h or later in 91.8% (95% CI 84.6 to 96.8); urticaria 63.8%; any gut symptom 69.2%
• UK government advice is that pregnant women and women trying to conceive should not eat liver or liver products such as pâté. — pregnant women and women trying to conceive, UK Evidence E source
  Avoid liver and liver products because of excess vitamin A risk to the unborn child

What people believe that the data does not support

• The EU rejected a claim that beef and other foods from the Tradilin omega-3 supply chain help regulate carbohydrate metabolism, and no beef claim is authorized. — EU Register on nutrition and health claims, beef entries Evidence E source
  Beef in the register: 0 authorized, 2 non-authorized (POL-HC-7872, POL-HC-7873)

Who this works differently for

• In a crossover RCT in 23 calcium stone formers, two daily servings of beef left urinary stone risk the same as plant protein. — 23 normocalciuric patients with a history of calcium kidney stones, 8 women and 15 men (n = 23) Evidence B source
  No difference in urinary calcium, oxalate, citrate or Tiselius risk index between beef and plant protein diets
• In a crossover RCT in 17 breastfeeding women, eating 12 oz (339 g) of beef a day gave milk more arachidonic acid than a plant-based beef substitute. — 17 lactating women exclusively breastfeeding, two 6-day diet phases (n = 17) Evidence B source
  Arachidonic acid 0.41 vs 0.35 percent of milk fatty acids (P < 0.001); lauric acid 4.47 vs 9.32 percent

What is still unknown

• Vitamin A in Beef Wellington depends on the recipe: the UK homemade record lists 1070 ug retinol per 3.5 oz (100 g) while the US survey record lists 15 ug RAE. — CoFID 2021 code 19-552 vs USDA FNDDS food code 27214300 (fdc_id 2706501) (n = 2 records) Evidence E source
  Retinol 1070 ug per 3.5 oz (100 g) (CoFID) vs vitamin A 15 ug RAE per 3.5 oz (100 g) (FNDDS), about a 70-fold gap

The bottom line

Beef is often eaten for iron. In an 8 week randomized trial in 52 iron-deficient women who all took a 32 mg iron supplement, having it with 4 oz (113 g) of beef raised hemoglobin by the same 0.5 g/dL as having it with a plant-based meat substitute. Over 10 controlled studies in 397 adults, most of them women, adding red meat for 4 weeks or more raised hemoglobin by 2.36 g/L (95% CI 0.71 to 4.02), though those studies did not all randomize. Ferritin, the iron store, did not change significantly. Roasting keeps all the iron and zinc of beef in USDA tables and about 70% of its vitamin B12, but only half its vitamin B6, and that factor is for roasted beef in general, with no figure for beef baked inside pastry. Vitamin A is the strange number. The UK homemade record lists 1070 ug retinol per 3.5 oz (100 g) and the US record lists 15 ug, a gap of about 70-fold that neither dataset explains. A liver pate layer would fit the UK figure, but that is a guess. UK government advice is that pregnant women and women trying to conceive should not eat liver or liver products such as pate, so ask what is under the pastry. People with alpha-gal syndrome should avoid it too. In pooled observational data on 1162 patients, with wide variation between studies, 91.8% first reacted an hour or more after eating red meat, which makes the link easy to miss. Two smaller trials looked at specific groups. In 23 people who had formed calcium kidney stones, two servings of beef a day over a short 2 day metabolic phase left urinary stone markers the same as plant protein. In 17 breastfeeding women eating 12 oz (339 g) of beef a day for 6 days, milk carried more arachidonic acid, 0.41 against 0.35 percent of milk fats, and nobody measured what that meant for the babies. The EU register holds no authorized health claim for beef.
