Remember that fruit and vegetables contain a high proportion of water, so a fruit snack such as oranges can help your fluid replacement. To adequately rehydrate after your exercise session, aim to drink one and a half times the fluid you lost while exercising.

Spread it over the next two to six hours. You need to drink more fluid than you lost while exercising because you continue to lose fluid through sweating and urination for some time after you have finished your session. This page has been produced in consultation with and approved by:.

Ca plays a key role in the absorption process of vitamin B12 32 , In this study, although there was no difference in the folic acid intake between the two groups, the serum vitamin B6, vitamin B12, and 5-MTHF decreased in the VLW group and were associated with Ca intake from drinking water.

Furthermore, serum 1,25, OH 2 D 3 was associated with serum homocysteine. In our previous study, serum 1,25, OH 2 D 3 decreased in children consuming very low-mineral water and was negatively associated with Ca intake from drinking water In this study, methionine, a metabolite of homocysteine remethylating, was not different between the two groups, and cysteine, a metabolite of homocysteine transsulfuration, decreased in children drinking VLW.

In another study in rats, consuming purified water decreased cystine, an oxide of cysteine, and 2-hydroxybutyric acid, the by-product of homocysteine transsulfuration 35 data not shown. These findings supported that drinking very low-mineral water may repress homocysteine transsulfuration.

Disturbing serum B vitamins and 1,25, OH 2 D 3 status due to Ca deficiency in drinking water may be the key reason. Low cysteine levels will aggregate the insufficient Ca intake and Ca disorders by decreasing the absorption of vitamin D and K via decreasing taurine, which is synthesized from cysteine Dyslipidemia and lipid oxidation are risk factors for cardiovascular diseases 37 — Both homocysteine metabolism and Ca homeostasis disorders can disturb lipid metabolism and induce oxidative stress 19 , 20 , And the Ca intake from drinking water had a combinative effect with serum homocysteine.

Based on these findings, Ca deficiency in DDW may disturb lipid metabolism by increasing serum homocysteine, which may increase the risk of atherosclerosis in adulthood. The oxidation of LDL was considered a biomarker of oxidative stress cardiovascular system and the main atherogenic modification of LDL 42 , It has antigenic potential and contributes heavily to atherosclerosis-associated inflammation 44 , In this study, the serum oxLDL was only associated with the Ca, either the Ca intake from the drinking water and total Ca intake or the serum Ca level.

Calcium can disturb mitochondrial b-oxidation and regulate the cellular oxidation of low-density lipoprotein by arterial smooth muscle cells 20 , Calcium channel blockers can significantly inhibit the increase in ox-LDL levels in Dahl salt-sensitive rats receiving a high salt diet Though oxidative stress is considered the major cause of homocysteine-induced toxicity, the main pro-oxidant nature of homocysteine is forming disulfides induced by metals Some reports provide that the effects of homocysteine on vascular smooth muscle cells and endothelial cells are mediated by Ca 48 , These indicate that deficient Ca in drinking water threatens the cardiovascular system via inducing lipid oxidation, which relies mainly on serum Ca disorders, rather than high homocysteine.

Though the serum Ca was not associated with serum 1,25, OH 2 D 3 in this study, the disturbing of bone metabolism, which increased serum Ca when Ca intake was insufficient, was associated with serum 1,25, OH 2 D 3.

Therefore, serum 1,25, OH 2 D 3 can disturb either homocysteine metabolism or Ca metabolism, and then played a key role in cardiovascular risk by consuming very low-mineral water.

Some limitations to this study were reported in our previous paper For example, we only recorded the minerals in DDW of the four schools and the dietary intake of these children in and We cannot exclude the influence of dietary vitamins B12 and B6.

But those students lived in the same area and shared similar nutritional habits. And we excluded participants who consumed mineral or vitamin supplements. We may postulate that the dietary intake of vitamin B12 and B6 was similar between the two groups. Second, these children had no symptoms or signs of cardiovascular damage, as well as higher blood pressure or hs-CRP.

Children are in development, and their organs have a strong repair ability. They may not show a significant sign of cardiovascular dysfunction or morbidity. We can only use the cardiovascular biomarkers that can predict the risk of cardiovascular disease in adulthood, such as apolipoproteins and oxLDL, to evaluate the cardiovascular health of these children However, we did not collect blood samples of these children in Lack of the baseline of serum homocysteine, B vitamins, and biomarkers of the cardiovascular system makes it impossible to show the causal relationship between very low-mineral water consumption and cardiovascular damage.

Although the blood pressure of these children was similar in , it was also similar in and cannot support the baseline of cardiovascular system status was not different Thus, more studies are required to confirm this finding.

This study was the first trial to evaluate the association between long-term consumption of very low-mineral water and cardiovascular health in children.

We found that consumption of very low-mineral water, even though it is not the only source of daily drinking water, might disturb homocysteine and lipid metabolism, increase oxidative stress, and then threaten cardiovascular health in children.

Calcium and 1,25, OH 2 D 3 disorders induced by insufficient Ca intake might play a key role. Although further studies are required to confirm this finding, we still suggest that children drinking very low-mineral water or reverse-osmosis purified water are exposed to many health risks besides retarded bone development.
