I've read that cold water stops digestion which probably means it impedes blood flow and circulation, so it's less of a tax on the system to use warm water.
Still, to say cold water is harmful runs up against nature since had to take water at whatever temp it was available such as in cold mountain streams or in winter from a well..
I'm guessing the negative effects are marginal for normal day-to-day consumption.
Limit what you eat in terms of bad food and quantity. Drink more water. Exercise - I suggest tennis. Find work you like and can tolerate for the long term.
Read the article and you'll find a compilation of what recent research has confirmed and that is that your body needs rest from eating too, and not just exercise.
This is a high value approach to maintaining your overall health.
This is good news in a lot of ways. Most of us like chocolate milk more than sugary fruit tasting water. Based on this study at least it gives us chocolate lovers a legitimate argument for downing some after exercise. It's also less costly by a wide margin since it's considered a legacy treat rather than some fancy sport drink.
During matches I'd be more thoughtful of taking in electrolytes myself.
As you can see this story is old news being made new again.
This brings us back to basics. If you want carbs it comes down to versions of sugar and in the case of milk it's lactose. With chocolate milk you get the caffeine that comes with it in addition to the good taste. If you want a pure caffeine boost then there is always coffee but without protein and carbs you have only added a stimulant. It seems that chocolate milk covers all of the bases in a moderate amount with good taste as a bonus. I wouldn't overdo it but rather than spending so much on expensive health and sport drinks consider chocolate milk as another option.
Tennis Players: I'd probably not drink chocolate during the match but rather consider it a recovery option. During a match remember liquids, electrolytes, and even simple treats like bananas.
It's hard to avoid most pollution without relocation from the environment that has it. Instead, see if you can do the things necessary to nullify the bad effects. Exercise is the most important thing you can do for your health followed up by a good diet.
The most obvious thing you can agree with in this article is that growing your own food has many benefits that include higher levels of nutrition versus store bought food. There is no doubt that some vitamins and minerals help. I can give you a specific example. A potassium deficiency has all kinds of negative effects on the body including one I experienced and that is muscle spasms. A doctor prescribed potassium pills and it went away immediately after having been a multi year problem. Now, it's been a decade and since I make sure to continue taking either potassium supplements or eating foods that contain it I haven't had the spasm problem again.
That is just one example. Consider the benefits of natural intake first over vitamin supplements but aging also brings on the need for targeted supplementation for those of us that might have deficiencies or health issues that can benefit from them.
Consider wearing long sleeved shirts even when playing tennis. Modern fabrics allow it without overheating in the sun and give you a SPF 15-30 protection depending on the color and type of fabric. Putting Zinc Oxide based cream on your nose and top of your hands will give you some very targeted protection as well.

Pasta eaters healthier
In moderation pasta is a great thing. Combined with other foods that supply fat and protein in moderate amounts this can constitute a healthy diet and one that works well for tennis players that train many hours and need a heavy intake of calories.
Tennis players often think they have an unlimited allowance for carb intake since they spend so many hours burning calories. All you ever hear is pasta, pasta, pasta.
Though this is a great way to intake lots of calories it isn't necessarily the best way to limit inflammation and manage your overall health. A few weeks of forced rest due to injury and you'll see some love handles and the beginning of a stomach bulge where fat is stored.
Some people may have taken the step of not eating wheat due to worries about gluten and excess carbs that might also risk inflammation have taken a source of protein and carbohydrate out of their diets. One thing you might do it follow some of the advice of people who know more about methods of eating wheat. The article above is very detailed on the subject. It seems that the less it is modified and refined and the closer it is to its original state the more likely you'll get the benefits of it. Stay with organic and whole grain foods that include wheat and you'll experience some of the benefits of a natural diet that include good digestion, moderate sugar intake, high nutrients, and great fiber balance. What's not to like.
There are some diets out there that say your blood type can help you lose weight or control diseases. I can't say what is right on this other than what mainstream medicine concludes which is that it won't help in dieting.
Here is some webmd information on blood types that it is probably worth knowing. Since you are into sports any medical and health knowledge is a good thing.
New Study Says Fat is Good and No to Carbs
It would be nice if the experts would make up their minds. This has changed repeatedly over the years but for at least the past 20 years the idea was that carbs are better for you than fats. Now with the advent of massive health issues as a result of the bogus science new studies are challenging that long running trashing of the old food pyramid. Now a new pyramid will probably come into use that puts fats above all sources of calories.
Guess what? Now cheese, eggs, and butter are back on the dietary approved list according to newer studies after decades of ruining the party. 102 Year Old Woman in New Jersey says Eat Everything
