A glass of soda water has about as much iron as the average person on earth, but it has more calcium than the average human, according to a new study published online by The Wall St. Journal.

    The research by the U.K. team found that the best mineral in soda water is iron.

    But calcium is far more important than iron, and drinking it can cause iron-deficiency anemia.

    Iron is essential for brain development, bones, and the immune system, and it can prevent heart disease and cancer.

    And it has an antioxidant role.

    But drinking it in large amounts can have dangerous consequences.

    The study authors said that the new findings show that there’s a lot more to consider when choosing iron supplements.

    And they warn that consumers should consider whether a glass or a bottle of water is a good choice for drinking.

    The researchers examined data from nearly 10,000 adults in the United Kingdom and Europe who were randomly assigned to take either a water or soda-water capsule, or a placebo capsule.

    Both are similar to a capsule in that they contain a mix of minerals and vitamins and are fortified with a mix or mix of vitamins.

    For the study, the researchers used the World Health Organization’s International Classification of Diseases-10-class system to define the different minerals in the drink.

    The participants were asked to consume two capsules, one containing 0.1 grams of calcium and one containing 1.2 grams of iron.

    Each capsule contained between 10 and 15 milligrams of calcium, and each capsule contained up to 1 gram of iron, according the study.

    The investigators also analyzed the mineral composition of the capsules in the drinking water and water-based supplements, including supplements containing vitamins, minerals, and antioxidants.

    They found that about half of the calcium in the capsules came from foods, like fish and vegetables, with the rest coming from dairy, fruit, and nuts.

    That’s because the calcium that is found in dairy, fruits, and meat is much more likely to be in the form of calcium phosphate than in the calcium carbonate that is in the water- or supplement-based versions of the same foods, according a news release from the researchers.

    But the other half of calcium came from supplements, which included calcium carbonates and calcium gluconate, which is more common in the supplements.

    The calcium carbonated drink contained around 4.6 milligram of calcium per serving, and water with 0.5 milligms of calcium in it contained around 0.4 milliggram of calcium.

    The results are consistent with what many of us know from scientific studies: the amount of calcium is important, but so is the amount in the food, not the amount that is added to the water, the study authors wrote.

    The scientists found that drinking the water supplement had no effect on iron levels in the body.

    “There was no effect of the supplement on the levels of iron in blood or in urine,” said coauthor Andrew C. Treder, a professor of chemistry at Imperial College London.

    “The supplement was only marginally effective at improving iron status.”

    The researchers noted that the water capsules were similar to the one that is available for purchase on the internet.

    The drinks have become popular in recent years.

    According to a recent study by the United States Centers for Disease Control and Prevention, more than a quarter of the U to UK population drinks water at least once a week, while half of Americans consume water at more than twice a week.

    The best way to get all the minerals in a drink is to drink it in a water capsule, said co-author John G. Allen, a postdoctoral fellow at the University of Sussex.

    “We have to be really careful to consume all the calcium and other minerals in food and drink in a balanced way,” Allen said.

    The findings suggest that the health benefits of drinking a healthy diet in moderation are well worth the risk.

    “If you don’t get enough calcium, you can get some problems with your calcium,” said Tredar.

    “In the long run, it’s better to eat more protein and fewer carbs than not to eat enough protein and carbs.

    And if you’re a woman, you should eat lots of dairy, eggs, and fruits.”

    The study was funded by the British Heart Foundation.
