Butter cookies: what the saturated fat and sugar add up to

We found no trial of butter cookies themselves, so the evidence here comes from their ingredients. The firmest of it concerns saturated fat. A Cochrane meta-analysis of trials lasting at least two years, 53,300 adults in all, found that cutting saturated fat lowered combined cardiovascular events by 21 percent (RR 0.79, 95% CI 0.66 to 0.93). It had little or no effect on death from any cause. A medium 30 g butter or sugar cookie carries about 2.3 g of saturated fat, 8.2 g of sugars and 139 calories, figures from a US survey category that lumps butter and sugar cookies together. Butter on its own raised LDL cholesterol in a 4-week trial in 94 UK adults aged 50 to 75. The rise was 0.38 mmol/L more than on olive oil (95% CI 0.16 to 0.60), at 1.8 oz (50 g) of butter a day, which is far more than a few cookies contain.

The numbers, per 3.5 oz (100 g)

What a real portion looks like

• A medium butter or sugar cookie of 30 g provides about 139 calories, 8.2 g sugars and 2.3 g saturated fat. — US survey food code 53241500, Cookie, butter or sugar Evidence E source
  Per 100 g: 464 calories, 27.31 g total sugars, 7.666 g saturated fat; small 20 g, medium 30 g, large 45 g

What cooking and storage change

• Lab studies suggest acrylamide in baked goods forms mainly via the Maillard reaction and can be limited by lowering reducing sugars, asparagine, baking temperature and time. — Carbohydrate-rich food products, laboratory and processing studies Evidence D source
  Direction only: lower precursors, temperature and time reduce acrylamide formation
• Lab storage studies suggest acrylamide levels in most dry processed foods fall during storage, and freezing largely preserves them. — Processed foods stored under varied time, temperature and packaging Evidence D source
  Direction only: decreases in most matrices, largest in low-moisture products at 25 C or higher

What it does to your health

• In a 4-week RCT in 94 UK adults aged 50-75, eating 1.8 oz (50 g) of butter a day raised LDL cholesterol by 15 mg/dL (0.38 mmol/L) more than olive oil and 16 mg/dL (0.42 mmol/L) more than coconut oil. — Healthy men and women aged 50-75, Cambridgeshire UK, 50 g/day of the assigned fat for 4 weeks (n = 94) Evidence B source
  LDL-C +16 mg/dL (95% CI 7.3 to 25; metric: 0.42 mmol/L, 0.19 to 0.65) vs coconut oil; +15 mg/dL (95% CI 6.2 to 23; metric: 0.38 mmol/L, 0.16 to 0.60) vs olive oil
• A Cochrane meta-analysis of long-term RCTs found that cutting saturated fat lowered combined cardiovascular events by 21%, with little or no effect on total mortality. — Adults with or without cardiovascular disease, trials lasting at least 24 months (n = 53300) Evidence A source
  Combined cardiovascular events RR 0.79 (95% CI 0.66 to 0.93); all-cause mortality RR 0.96 (95% CI 0.90 to 1.03)
• Observational data from 15 cohorts link each daily tablespoon of butter to a 1% higher all-cause mortality and no change in cardiovascular disease. — General adult populations, 15 country-specific cohorts, 6.5 million person-years (n = 636151) Evidence C source
  Per 14 g/day: mortality RR 1.01 (95% CI 1.00 to 1.03); CVD RR 1.00 (0.98 to 1.02); diabetes RR 0.96 (0.93 to 0.99)

Safety, limits and interactions

• A meta-analysis of processing contaminants in wheat foods found acrylamide was mostly studied in bread, cookies and pasta, at a pooled level of about 136 micrograms per kg. — Published measurements in wheat-based foods, 28 studies in the meta-analysis (n = 28 studies) Evidence C source
  Pooled acrylamide 136.29 ug/kg; HMF 70.59 ug/kg; PAHs 0.11 ug/kg

What people believe that the data does not support

• In a 2006 US supermarket label survey, 34 of 44 cookies and snack cakes were labeled 0 g trans fat, yet the authors found that some products in the survey, across categories, still contained substantial amounts. — Packaged cookies and snack cakes on sale in one Minneapolis-St Paul supercenter, July 2006 (n = 44) Evidence C source
  34 of 44 labeled 0 g trans fat

Who this works differently for

• Observational data from 53,870 mother-newborn pairs link the highest acrylamide biomarker quartile in pregnancy to 131 g lower birth weight. — Pregnant women and newborns, five epidemiological studies (n = 53870) Evidence C source
  Highest AA-Hb quartile: SGA OR 1.20 (95% CI 1.08 to 1.33); birth weight -131 g (95% CI -204 to -58)

The bottom line

The picture from ordinary eating is weaker. Across cohorts with 636,151 adults, each daily tablespoon of butter was associated with a 1 percent higher death rate (RR 1.01, 95% CI 1.00 to 1.03) and with no change in cardiovascular disease. That is a weak association from observational data, and it is about butter, with cookies never looked at separately. Labels were once a poor guide. In a 2006 survey of one Minneapolis supercenter, 34 of 44 cookies and snack cakes said 0 g trans fat, and the authors found that some products across the store still carried substantial amounts. That was before the US ban on partially hydrogenated oils, and the survey read labels without testing the food. Browning brings acrylamide. A meta-analysis of wheat foods put the pooled level at about 136 micrograms per kg, averaged over bread, cookies, pasta and other products with no separate figure for cookies. Laboratory work suggests less of it forms with fewer reducing sugars and less asparagine in the dough, a lower oven temperature and a shorter bake. Storage studies found acrylamide fell in most dry foods over time, most in coffee, cocoa and nuts, with cookies not reported on their own. Who should be careful. In five studies of 53,870 mothers and newborns, the highest quarter of an acrylamide blood marker in pregnancy was linked to babies 131 g lighter at birth (95% CI 58 to 204 g) and to higher odds of being small for gestational age (OR 1.20). That is acrylamide from the whole diet, cookies were not assessed, and the data show an association.
