    Drinking water increases calories burned, cuts risk of dying from coronary heart disease by half

    "[R]ecently, water drinking was shown to increase energy expenditure," notes a new paper from Germany. "The increase in energy expenditure with water drinking should be recognized as an important confounding variable in metabolic studies and may hold some promise as an adjunctive measure in the prevention or treatment of obesity," they conclude. Drinking water stimulates SNS

    Drinking water has been found to stimulate the sympathetic nervous system, although the cause of this, is not known.

    High water intake cuts risk of dying from coronary heart disease in half

    Here is another reason to drink plenty of water.

    A high water intake can cut your risk of dying from coronary heart disease roughly in half according to a 2002 study from Loma Linda University.

    Five glasses of water vs two glasses cuts risk in men by 54%, in women 41%

    Drinking five or more glasses of water per day lowered the risk of dying from coronary heart disease by 54 percent in men, and 41 percent in women.

    Fluids other than water increase the risk of dying 46-147%

    This was not true for fluids other than water. In fact, they had the opposite effect.

    Drinking five or more glass of fluids other than water was associated with 147 percent increase (2.47 fold) in the risk of dying from coronary heart disease in men, and a 46 percent increase (1.46 fold) in women.

    Findings unchanged after adjusting for age, BMI, etc

    These findings remained unchanged even after adjusting for age, smoking, hypertension, body mass index (BMI), education, and hormone replacement therapy in women.

    Subjects: 8,280 men and 12,017 women

    The study followed 8,280 men and 12,017 women, 38- to 100-years-old, who were without heart disease, stroke, or diabetes in 1976 in the Adventist Health Study, and followed for six years.

    What liquids, other than water, were the men and women drinking that caused such a high increase in deaths? There should be warnings for people to stop drinking the problem liquids and switch to water.

    Elaine,

    The other liquids are "everything except water", however, alcohol was not included because only 11 percent Seventh Day Adventist -- 1 out of 9 people --, who were the subjects of this study, drank alcohol, and when they do, it is in very small amounts.

    Other fluids included milk, coffee, tea, herbal tea, fruit juice and sodas.

    I interpret the results of this study a little differently than perhaps you did.

    I would not necessarily say that all other fluids increased the risk of death from coronary heart disease -- although they might by causing dehydration with liquids which contain caffeine such as coffee, tea and colas -- but rather that water decreases the risk, whereas all other fluids combined may not.

    Other studies have found that tea decreases the risk of heart disease.

    If I remember correctly, research from 25 years ago or more suggested that the homogenization process of milk destroys an enzyme called xanthine oxidase that may increase the risk of heart disease.

    Again, if I remember correctly, I believe I also remember reading a study some time ago which found that wine was associated with roughly a 50 percent decrease in the risk of dying from heart disease, beer had no effect, and liquor was associated with a 50 percent greater risk of dying from heart disease.

    However, as noted above, alcohol was not included in this study.

    I forgot to include the reference for this study. Here it is:

    I once read an article that found that, contrary to popular belief, the more water given animals, the MORE food they eat. One article on this site describes Barbara Rolls' work, showing that water in soup, but not water drank alone, decreased the amount eaten in the main entree that followed.

    Are you aware of any such study correlating water drinking to appetite?

    Thank you.

    J Risser,

    I have not seen any studies suggesting that water increases food intake.

    Some people, like Weight Watchers, I believe, suggest that people drink a glass of water before a meal to reduce food intake, but, as you noted, at least one study found that this did not affect food intake long term.

    But the study summarized above suggests that drinking more water is one of the best things that we can do for our health.

    I was able to track down an article on the association between DEcreased water intake and DEcreased food consumption in military recruits.

    **A significant correlation between hypohydration (as indicated by rapid body weight loss) and food intake was found: the more hypohydrated the individual, the smaller the quantity of food consumed (Engell 1993). The results of the studies reviewed in this section indicate that hypohydration rather than peripheral thirst sensations is probably responsible for the voluntary reduction of food intake associated with limited water consumption. Elevated thirst is not associated with reduced food consumption unless it is associated with hypohydration (as indicated by rapid body weight loss or elevated urine-specific gravity). **

    Laboratory and field studies have demonstrated that hypohydration leads to reduced food intake, and hypohydration (as indicated by elevated urine-specific gravity levels) has been observed repeatedly in field studies (Edwards et al., 1989; Francesconi et al., 1987; Popper et al., 1987; Salter et al., 1991).

    I have not found a study where decreasing water intake was used as a strategy for weight loss, probably due to concerns of developing dehydration and its side effects. It does raise serious doubts, though, whether more water is better in enhancing weight loss.

    J. Risser,

    Thank you for the information.

    I have not read about this before.
