There’s one very simple health "test" you can do every day—several times a day, if you want—that can give you a bit of insight into your overall health and nutrition.
At the risk of engaging in a bit of bathroom talk, just look at your urine and check the color. A natural, healthy color for your liquid output is pale yellow, but I’ll be honest, many mornings I’m looking at something that looks more like VERY concentrated lemonade or some sort of TANG derivative, and that’s because I struggle to make sure I drink enough water, and not just soft drinks. Honestly, ever since I started to be more aware of the color of my urine, I almost have a little competition with myself to see how many bathroom visits in a row I can make sure it’s within a more healthy range of hues.
Other colors to be aware of, and what they mean: Very dark yellow could mean liver problems, or severe dehydration. Brown urine can could be caused by liver disease, hepatitis, melanoma cancer,
or copper poisoning. Cloudy or murky urine could indicate a urinary tract infection.
