Fudge cookies: the sugar counts, the cocoa barely does

In a meta-analysis of randomized trials in adults eating freely, adding sugars raised body weight by 1.7 lb (95% CI 0.66 to 2.6; metric: 0.75 kg, 0.30 to 1.19) and cutting them lowered it by 1.8 lb (0.86 to 2.7; metric: 0.80 kg, 0.39 to 1.21), through the extra energy. That is the strongest evidence that touches a fudge cookie, and cookies are one sugar source among many in it. A medium chocolate or fudge cookie of 30 g carries about 130 calories and 11 g of sugar in US survey data, and a large 45 g one about 195 calories, 17 g of sugar and 6.4 g of fat. Those figures come from a single recipe entry that lumps chocolate and fudge cookies together, and shop cookies come in many sizes. Per 100 g the entry lists 433 calories and 37 g of sugar. We found no study of fudge cookies themselves on any health outcome.

The numbers, per 3.5 oz (100 g)

How much is actually in it

• Acrylamide formed in baking averaged 343 ug/kg across 80 commercial biscuits in Spain, ranging from under 20 to 2144 ug/kg. — 80 commercial biscuits marketed in Spain, 2019 (n = 80 products) Evidence C source
  Mean 343 ug/kg (range <20 to 2144); 70% below the EU benchmark; wheat-based formulations down 45% since 2007

What a real portion looks like

• A medium chocolate or fudge cookie (30 g) carries about 130 calories and 11 g sugar, a large one (45 g) about 195 calories and 17 g sugar. — US household measures, FNDDS (n = 1 food code) Evidence E source
  Per 100 g: energy 433 calories, total sugars 37.43 g, fat 14.2 g; small 20 g 86.6 calories; medium 30 g 129.9 calories, 11.2 g sugar; large 45 g 194.8 calories, 16.8 g sugar, 6.4 g fat

What cooking and storage change

• A meta-analysis of 28 studies on wheat foods found acrylamide was the main baking contaminant, with cookies among the most studied products. — wheat-based foods: bread, cookies, pasta, cakes (n = 28 studies) Evidence C source
  Acrylamide pooled 136.29 ug/kg; HMF 70.59 ug/kg (four cookie studies); PAHs 0.11 ug/kg

What it does to your health

• In a meta-analysis of trials in adults eating freely, adding sugars raised body weight by 1.7 lb (0.75 kg) and cutting them lowered it by 1.8 lb (0.80 kg). — adults on ad libitum diets in randomized trials of at least two weeks (n = 30 trials) Evidence A source
  Reduced sugars -1.8 lb (95% CI 0.86 to 2.7; metric: -0.80 kg, 0.39 to 1.21); increased sugars +1.7 lb (0.66 to 2.6; metric: 0.75 kg, 0.30 to 1.19); isoenergetic swap 0.09 lb (0.04 kg)

Safety, limits and interactions

• Observational data across 32 publications do not tie dietary acrylamide to most common cancers, with only a borderline kidney cancer signal, RR 1.20. — participants of cohort and case-control studies on 14 cancer sites (n = 32 publications) Evidence C source
  Kidney cancer RR 1.20 (95% CI 1.00 to 1.45) high vs low intake; other sites null; never-smokers endometrial RR 1.23 (1.00 to 1.51)

What people believe that the data does not support

• Across 31 RCTs with 1986 adults, cocoa extract or dark chocolate of at least 70% cocoa lowered LDL by 9.47 mg/dL and systolic pressure by 2.52 mmHg. — adults with and without comorbidities, cocoa extract or >=70% dark chocolate for at least 4 weeks (n = 1986) Evidence A source
  LDL -9.47 mg/dL (95% CI -13.75 to -5.20); SBP -2.52 mmHg (-4.17 to -0.88); no effect on body weight or BMI
• The EU did not authorize the claim that cocoa flavanols maintain normal blood pressure, so chocolate products may not carry it. — EU health claim application Evidence E source
  Claim non-authorized

Who this works differently for

• In 145 RCTs with 5205 people, about 586 mg of flavan-3-ols a day cut office blood pressure by 2.8/2.0 mmHg, more in people with high blood pressure. — participants of 145 RCTs taking flavan-3-ol-rich cocoa, tea, grape or apple products or supplements (n = 5205) Evidence A source
  Office BP -2.8 (95% CI -3.9 to -1.7) / -2.0 (-2.6 to -1.3) mmHg; elevated or hypertensive baseline -5.9/-2.7 mmHg

What is still unknown

• Evidence on sweet bakery products and health is thin: a Nordic review of systematic reviews found none on sugary foods other than chocolate and cocoa. — systematic reviews 2011-2021 on sweets and sugary foods (n = 12 reviews) Evidence C source
  No systematic review on sugary foods other than chocolate; chocolate links rated low or very low

The bottom line

The cocoa is the part people hope does some good, and the trials behind that hope did not use cookies. In a meta-analysis of randomized trials, cocoa extract or dark chocolate with at least 70% cocoa lowered LDL cholesterol by 9.47 mg/dL (95% CI 5.20 to 13.75) and systolic blood pressure by 2.52 mmHg (0.88 to 4.17). Another meta-analysis of randomized trials of flavan-3-ol-rich cocoa, tea, grape or apple products and supplements found office blood pressure fell by 2.8/2.0 mmHg with regular intake, at doses far above what a fudge cookie supplies. The EU did not authorize the claim that cocoa flavanols maintain normal blood pressure, which means the evidence put forward fell short when it was assessed. A sugary baked cookie is a different food from the products those trials tested. Baking forms acrylamide. Across 80 commercial biscuits sold in Spain the mean was 343 mcg/kg, ranging from under 20 to 2144 mcg/kg, with 70% below the EU benchmark, and fudge cookies were not reported separately. Rye, teff and oat biscuits were the highest. A meta-analysis of occurrence studies on wheat foods found bread, cookies and pasta were the most studied, and acrylamide had the highest pooled concentration of the contaminants measured, at 136.29 mcg/kg. Who should take care. Observational data on dietary acrylamide, with intake estimated from questionnaires, found no meaningful associations for most cancers. The exception was a borderline signal for kidney cancer, a relative risk of 1.20 (95% CI 1.00 to 1.45) at the highest against the lowest intake. That is the only card we hold on the caution side. We have no evidence card on allergy, children, pregnancy or medicines for fudge cookies, so those questions stay unanswered here. The wider picture is thin for a specific reason. A Nordic review of systematic reviews on sweets found none on sugary foods other than chocolate and cocoa, so cookies have simply not been reviewed as a group.
