Strawberry milk: the calcium of milk with sugar added
In a meta-analysis of randomized trials in children, replacing sugar-sweetened drinks with either zero-calorie drinks or flavored milk lowered body fat by 0.70 percentage points (95% CI 0.62 to 0.78), in only three trials that pooled milk with the zero-calorie drinks. The same swap did not change BMI z-score in two trials (minus 0.05, 95% CI minus 0.20 to 0.09). In a meta-analysis of controlled feeding studies in people with and without diabetes, sweetened low fat milk eaten in place of other energy for at least a week raised fasting insulin by about 19 pmol/L (95% CI 9 to 29). That result rests on two study comparisons of sweetened milk in general, in a review whose evidence was rated low overall. A 248 g cup, the size of a US school carton, gives about 161 calories, 21 g of total sugars, 300 mg calcium and 7.9 g protein, and the sugar figure counts the lactose that plain milk already has along with the added sugar. The whole milk version comes to about 213 calories and 29 g sugars.

How much is actually in it
- UK composition data for strawberry or banana flavored milk give 64 calories and 8.9 g sugars per 3.5 oz (100 g), of which 3.9 g sucrose and 4.9 g lactose, close to the US value of 65 calories and 8.45 g. — CoFID 12-326 Milk, flavored, pasteurized, strawberry, banana; per 3.5 oz (100 g) Evidence E sourceCoFID: 64 calories, total sugars 8.9 g (sucrose 3.9, lactose 4.9), calcium 120 mg, fat 1.5 g; FNDDS NFS: 65 calories, sugars 8.45 g, calcium 121 mg
What a real portion looks like
- One cup (248 g) of US strawberry milk provides about 161 calories, 21 g total sugars, 300 mg calcium and 7.9 g protein, and the whole milk version about 213 calories and 29 g sugars. — US FNDDS Strawberry milk, NFS and Strawberry milk, whole; 1 cup = 1 school container = 248 g Evidence E sourceNFS per cup: 161.2 calories, 21.0 g sugars, 300.1 mg calcium, 7.9 g protein, 2.7 ug vitamin D; whole: 213.3 calories, 29.0 g sugars
What it does to your health
- A meta-analysis of randomized trials in children found that swapping sugar-sweetened drinks for non-caloric drinks or flavored milk cut body fat by 0.70 percentage points without changing BMI z-score. — Children and adolescents in randomized controlled trials (n = 3 RCTs (body fat), 2 RCTs (BMI z-score)) Evidence A sourceBody fat % -0.70 [-0.78, -0.62]; BMI z-score -0.05 [-0.20, 0.09], p = 0.48
- In a meta-analysis of controlled feeding trials, sweetened low fat milk replacing other energy raised fasting insulin by about 19 pmol/L, based on two study comparisons. — People with and without diabetes in controlled intervention studies lasting at least 7 days, energy-matched substitution designs (n = 2 study comparisons) Evidence B sourceFasting insulin +18.95 pmol/L (95% CI 9.09 to 28.80), P<0.001
- A systematic review of 13 mostly non-randomized studies in children found flavored milk raised total milk intake in 11 studies and energy intake in 5 of 7. — Children aged 1 to 18 years (n = 13 studies) Evidence C sourceMilk intake up in 11/13; energy intake up in 5/7; weight gain up in 1/3
What people believe that the data does not support
- US survey data link flavored milk drinking in teenage girls with calcium intake close to plain milk drinkers (992 vs 1,038 mg/day) and far above non-drinkers (576 mg/day). — 7,557 US children and adolescents aged 2 to 18 years, NHANES 1999-2002 (n = 7557) Evidence C sourceGirls 12-18 y calcium: flavored 992 ± 41.5, plain 1,038 ± 22.5, none 576 ± 11.7 mg/day; added sugars not different vs non-drinkers
Who this works differently for
- A systematic review of US school lunch studies reports that removing flavored milk from schools may reduce how much milk children drink. — US K-12 students in the National School Lunch Program, studies after 2012 (n = 30 studies) Evidence C sourceDirection only: flavored milk removal may decrease milk consumption; no pooled size
- In 69 women losing weight over 6 months, strawberry milk with 15% sucrose became better liked than the 30% version, which both groups had liked equally at the start. — Women with obesity (BMI 34.4, age 44.2 y) on a low-fat or low-carbohydrate diet for 6 months (n = 69) Evidence C sourceAt 6 months the 15% sucrose sample was highest liked (P < 0.007); no effect of diet type
The bottom line
In the UK table for strawberry or banana flavored milk, 3.9 g of the 8.9 g sugars per 3.5 oz (100 g) is sucrose and 4.9 g is lactose, and that record does not separate the two flavors. A review of 13 mostly non-randomized, high-bias studies in children, over half funded by industry or undisclosed, found flavored milk raised total milk intake in 11 and energy intake in 5 of the 7 that checked. Weight gain rose in 1 of the 3 that looked. Observational US survey data from single-day food recalls link flavored milk in girls aged 12 to 18 with calcium intake of 992 mg a day, close to the 1,038 mg of plain milk drinkers and far above the 576 mg of girls who drank none. In that survey, which had non-government funding, flavored milk drinkers took in no more added sugar than children who drank no milk. A review of US school lunch studies says removing flavored milk from schools may lower how much milk children drink, and it gives a direction with no size. In 69 women with obesity on a six-month weight loss diet, milk with 15 percent sucrose came to be liked more than the 30 percent version they had liked equally at the start, a change over time measured on taste alone. We have no evidence card on lactose intolerance, milk allergy or medicines for strawberry milk, so the page has no safety section, and that is a gap in what we found.

Of 3978 studies identified, 13 met inclusion criteria. Ten studies were experimental and three were longitudinal cohort studies. Eleven studies found that flavored milk increased overall milk intake, five of seven studies that examined energy intake showed that flavored milk increased energy intake, and one of three studies that assessed obesity outcomes demonstrated an increase in weight gain with flavored milk consumption. Only one study was a randomized controlled trial, most studies had high bias, and over half were industry-funded or did not disclose funding.
