ABSTRACT Consumption of sugar-sweetened soda has been associated with an increased risk of cardiometabolic disease. The relation with cerebrovascular disease has not yet been closely examined.
Our objective was to examine patterns of soda consumption and substitution of alternative beverages for soda in relation to stroke risk.
The Nurses' Health Study, a prospective cohort study of 84,085 women followed for 28 y (1980-2008), and the Health Professionals Follow-Up Study, a prospective cohort study of 43,371 men followed for 22 y (1986-2008), provided data on soda consumption and incident stroke.
We documented 1416 strokes in men during 841,770 person-years of follow-up and 2938 strokes in women during 2,188,230 person-years of follow-up. The pooled RR of total stroke for ≥ 1 serving of sugar-sweetened soda/d, compared with none, was 1.16 (95% CI: 1.00, 1.34). The pooled RR of total stroke for ≥ 1 serving of low-calorie soda/d, compared with none, was 1.16 (95% CI: 1.05, 1.28). Compared with 1 serving of sugar-sweetened soda/d, 1 serving of decaffeinated coffee/d was associated with a 10% (95% CI: 1%, 19%) lower risk of stroke and 1 serving of caffeinated coffee/d with a 9% (95% CI: 0%, 17%) lower risk. Similar estimated reductions in risk were seen for substitution of caffeinated or decaffeinated coffee for low-calorie soda.
Greater consumption of sugar-sweetened and low-calorie sodas was associated with a significantly higher risk of stroke. This risk may be reduced by substituting alternative beverages for soda.

    ABSTRACT: BACKGROUND: Soft drink intake has been associated with obesity and diabetes, but its relation with risk of cardiovascular disease (CVD) is limited. OBJECTIVE: We examined the association between soft drink intake and risk of CVD in a Japanese population. DESIGN: This was a prospective study in 39,786 Japanese men and women aged 40-59 y in which soft drink intake was determined by using a self-administered food-frequency questionnaire. Follow-up was from 1990 to 2008. HRs and 95% CIs of incidence were calculated according to categories of soft drink intake. RESULTS: During 18 y of follow-up, we ascertained 453 incident cases of ischemic heart disease (IHD) and 1922 cases of stroke, including 859 hemorrhagic and 1047 ischemic strokes. Soft drink intake was positively associated with risk of total stroke and more specifically ischemic stroke for women; the multivariable HR (95% CI) in the highest soft drink intake (almost every day) category compared with the lowest intake (never or rarely) category was 1.21 (0.88, 1.68; P-trend = 0.02) for total stroke and 1.83 (1.22, 2.75; P-trend = 0.001) for ischemic stroke. That association did not change significantly after the exclusion of early incident cases within 3-9 y from baseline. A nonsignificant inverse trend for risks of total and ischemic strokes was shown for men, and it was weakened after the exclusion of early incident cases or after the exclusion of participants with baseline comorbidities. Soft drink intake was not associated with risk of IHD or hemorrhagic stroke for either sex. CONCLUSION: Soft drink intake is associated with higher risk of ischemic stroke for women.

    ABSTRACT: Abstract Using a stepwise assessment of the exposure of Korean consumers to acesulfame K and sucralose, theoretical maximum daily intakes of the sweeteners were calculated using the Budget screening method, which resulted in values greater than the acceptable daily intakes (ADIs). Accordingly, the daily intakes of the sweeteners based on food consumption data and concentrations determined by instrumental analysis of 605 food samples were estimated for the more refined approach. The estimated daily intakes (EDIs) of all ordinary consumers were lower than the ADI, which was considered safe. However, for infants and 95th percentile high-level consumers (especially those who choose sucralose-containing foods), the EDIs of sucralose were very close to and higher than the ADI. Therefore, the sucralose concentration in sweetened beverages should be reduced; this would benefit the health of both high-level consumers and infants.
