An apple fruit keeps awake than caffeine

Today’s Amazing Fact:  

An apple fruit keeps awake than caffeine

Eating an apple is a more reliable method of staying awake than consuming a cup of coffee. The natural sugar in an apple is more potent than the caffeine in coffee.

According to "The Goodman and Gilman Manual of Pharmacology and Therapeutics," caffeine, which is a stimulant found in many foods, is the most widely-used psychoactive drug in the world. Although coffee has high caffeine content, apples do not. Therefore, there is more caffeine in a cup of coffee than in an apple. There is more sugar in an apple than in coffee; however, this sugar has a relatively low glycemic index, and therefore won't have as rapid an onset of action as the sugar you add to your cup of coffee.

Apples are a good source of many nutrients. For example, a typical small apple has 12 percent of your daily recommended intake of fiber, 10 percent of your daily recommended intake of vitamin C, and trace amounts of minerals such as calcium, potassium, and manganese. However, apples do not contain any caffeine. There is actually no caffeine in an apple. The nutrient that associates apples with energy is actually the sugar contained within. An apple will thus act as energy over a longer period of time than a regular caffeine supplement.

Presuming you put one to two sugar packets in your typical cup of coffee, and that each sugar packet contains about 4 g of sugar, the answer is yes, a typical apple contains more sugar than a typical cup of coffee. However, if you compare the glycemic index of apples and typical table sugar the glycemic index being a measurement of how quickly an ingested glucose load finds its way into your bloodstream, and hence a measure of how quickly you feel the effects of ingestion you'll see that apples, at 38 out of 100, are about half as strong as table sugar, at 68. So if you're looking for a quick energy kick, a cup of coffee is likely to get you there faster. However, an apple is probably your healthiest option.

Apples can also bolster your health in ways that benefit early morning activities. Apples contain high levels of phytonutrients, antioxidants that give apple skin its color. Eating apples regularly improves your breathing. If you eat more than two apples weekly, your bronchial tubes react less violently to irritants and your risk of asthma falls, according to an article published in "Nutrition Journal" in 2004. Flavonoids in apples improve lung function, protecting you from lung cancer and from chronic obstructive pulmonary disease. If you eat five or more apples every week, your lungs could hold 138 milliliters more air during a forced expiratory volume test, compared to someone who doesn't eat apples.
