A Java A Day will take your “Fatty Blues” away

Boost to Athleticism

It's also caffeine -- and not coffee, per se -- that makes java a powerful aid in enhancing athletic endurance and performance. So powerful, in fact, that until recently, caffeine in coffee or other forms was deemed a "controlled" substance by the Olympic Games Committee, meaning that it could be consumed only in small, designated amounts by competing athletes.

Caffeine stimulates the brain and nervous system to do things differently, including signaling you to ignore fatigue or recruit extra units of muscle for intense athletic performance. Caffeine may even have a direct effect on muscles themselves, causing them to produce a stronger contraction. But what's amazing about it is that unlike some performance-enhancing manipulation some athletes do that are specific for strength or sprinting or endurance, studies show that caffeine positively enhances all of these things.

Coffee, as you probably know, makes you more alert, which can boost concentration. But claims that it improves a child's academic performance can be exaggerated. Coffee-drinking kids may do better on school tests because they're more awake, but most task-to-task lab studies suggest that coffee doesn't really improve mental performance.

But it helps kids' minds in another way. A study from Brazil finding that children who drink coffee with milk each day are less likely to have depression than other children. In fact, no studies show that coffee in reasonable amounts is in any way harmful to children.

On the flip side, it's clear that coffee isn't for everyone. Its legendary jolt in excess doses -- that is, more than whatever your individual body can tolerate -- can increase nervousness, hand trembling, and cause rapid heartbeat. Coffee may also raise cholesterol levels in some people and may contribute to artery clogging. But most recent large studies show no significant adverse effects on most healthy people, although pregnant women, heart patients, and those at risk for osteoporosis may still be advised to limit or avoid coffee. However, coffee with too much sugar added will be bad in the long run. But it is the table sugar added which is harmful but not the coffee itself.

In other words, consume enough caffeine -- whether it's from coffee or another source -- and you will likely run faster, last longer and be stronger. But the harder you exercise, the more benefit you may get from coffee.

But you can get other benefits from coffee that have nothing to do with caffeine. Coffee is loaded with antioxidants, including a group of compounds called quinines increases their insulin sensitivity. This increased sensitivity improves the body's response to insulin.

That may explain why those drinking decaf coffee but not tea beverages also showed a reduced diabetes risk, though it was half as much as those drinking caffeinated coffee.

Coffee has large amounts of antioxidants such as chlorogenic acid and tocopherols, and minerals such as magnesium. All these components have been shown to improve insulin sensitivity and glucose metabolism.

Meanwhile, Italian researchers credit another compound called trigonelline, which gives coffee its aroma and bitter taste, for having both antibacterial and anti-adhesive properties to help prevent dental cavities from forming.
