Fluids and heart disease

[Guest guest]

Hi All,

The below PDF available paper looked at fluid intake and heart disease.

Five or more versus two or less glasses of water made a large difference in

heart disease.

Non-water fluids had the opposite association. Caffeine-containing

beverages had a non-significant negative effect and milk none. That leaves

mainly fruit juice and sodas, which were taken too few to give significant

numbers.

Many in our group, including me, and others outside it have said fluids

other than water count positively too.

Not for heart disease it seems to me.

I am surprised.

I take about 1500 ml water/day, which I suppose is about 5.5 glasses. Other

liquid is coffee of 400 ml or 1.4 glasses and 100 ml soda.

Cheers, Al.

Water, other fluids, and fatal coronary heart disease: the Adventist Health

Study.

Chan J, Knutsen SF, Blix GG, Lee JW, Fraser GE.

“Whole blood viscosity, plasma viscosity, hematocrit, and fibrinogen are

considered independent risk factors for coronary heart disease and can be

elevated by dehydration. The associations between fatal coronary heart

disease and intake of water and fluids other than water were examined among

the 8,280 male and 12,017 female participants aged 38-100 years who were

without heart disease, stroke, or diabetes at baseline in 1976 in the

Adventist Health Study, a prospective cohort study. A total of 246 fatal

coronary heart disease events occurred during the 6-year follow-up. High

daily intakes of water (five or more glasses) compared with low (two or

fewer glasses) were associated with a relative risk in men of 0.46 (95%

confidence interval (CI): 0.28, 0.75; p trend = 0.001) and, in women, of

0.59 (95% CI: 0.36, 0.97). A high versus low intake of fluids other than

water was associated with a relative risk of 2.47 (95% CI: 1.04, 5.88) in

women and of 1.46 (95% CI: 0.7, 3.03) in men. All associations remained

virtually unchanged in multivariate analysis adjusting for age, smoking,

hypertension, body mass index, education, and (in women only) hormone

replacement therapy. Fluid intake as a putative coronary heart disease risk

factor may deserve further consideration in other populations or using other

study designs.”
