Healthy Eating Caffeine

Healthy Eating Caffeine?

You may be wondering what a page about caffeine consumption is doing on a healthy eating website. However, unless you are particularly sensitive to this popular stimulant or have a condition that precludes its use, there is no real evidence that moderate use of caffeine will inhibit your healthy eating goals.

Having said that, it is important that you consider the source of your caffeine. Coffee and tea contain antioxidants that have health benefits and even very dark chocolate (at least 70% cacao) is being promoted as healthy in small amounts.

What is it?

Caffeine comes from several plant sources including tea leaves, coffee beans, cocoa beans (chocolate), guarana and kola nuts.

It is a stimulant that enhances alertness and lessens the feeling of tiredness.

Since caffeine is a vaso-restrictor (makes the veins smaller), it can help with the pain of headaches that is due to dilated veins in the head.

It is difficult to find justification for including caffeinated soft drinks or sugary coffee concoctions in your healthy eating plan.

Most of the caffeine in cola comes from additives derived from coffee, although kola nuts have some caffeine in them naturally.The level of caffeine in tea depends on the type of tea, where the tea was grown, the time of year the tea leaves were picked among other factors.

Guarana (pronounced gwa-ra-NAH) is one of the richest sources of caffeine, containing up to three times the amount of caffeine as is present in coffee beans. It has recently become a popular ingredient in energy drinks in the U.S., but has long been used in South America as a "tonic."

In case you were wondering, the US RDA considers caffeine to be generally recognized as safe (GRAS).

At last count, 80-90 percent of adults and children in North America consume at least some caffeine daily, which helps to make caffeine the most widely used psychoactive (affects mind or mental processes) substance in the world.

The intensity of response to caffeine varies greatly, since not everyone metabolizes caffeine at the same rate. For this reason, caffeine may affect people differently with regard to blood pressure, insomnia and other side effects.

What are the side effects?

The potential effects of consuming caffeine include irritability, headache, upset stomach, insomnia, nervousness, acid reflux and diarrhea. Regular caffeine intake may also lead to chronic fatigue.

Caffeine may cause anxiety as well as depression because of the way it alters brain chemistry and it can be addictive.

In addition, too much caffeine may upset normal bowel rhythm, which may cause irregularity.

It may also act as a mild diuretic, causing you to lose water. It has been estimated that it takes approximately 3 cups of water to compensate for the dehydrating effects of caffeine.

Who should NOT use it?

Some people are so sensitive to the effects of caffeine, they must avoid it altogether. It should also be avoided is you suffer from ulcers, acid-reflux, PSVT (heart arrythmia) or Irritable Bowel Syndrome (IBS).

In some women, caffeine can aggravate fibrocystic breast disease (a harmless but annoying condition where the breasts get lumpy).

If you are pregnant, you should know that researchers have found that consuming five or more cups of coffee per day doubles the risk of miscarriage. In addition, breast feeding mothers should limit their intake of caffeine since it will pass through their milk to the baby.

Those who are prone to migraine headaches, have Crohn’s disease, hiatal hernia or osteopenia, also may have to eliminate caffeine from their diet.

It should also be noted here that caffeine may increase craving for alcohol in alcoholics and recovering alcoholics.

Can you be healthy eating caffeine?

Aside from the obvious reasons we consume caffeinated products, to clear brain fog, keep us alert and enhance our mood, there seem to be some other benefits as well.

Both coffee and tea, two of the usual sources of caffeine in the diet are significant sources of antioxidants.

On the mental health front, recent studies had suggested that caffeine may help deter mental decline in dementia and Alzheimer’s Disease patients. Some studies have also shown that coffee drinkers are less likely to develop Alzheimer’s Disease. Stay tuned.

Caveat for healthy eating caffeine: If you habitually use caffeine to mask your body's need to sleep, you will pay a price in the long run. Your physical and mental health will suffer if you constantly override your body's built-in warning signals that you need to rest.
