Fetal exposure to moderate/high caffeine levels linked to excess childhood weight gain

BMJ: Exposure to moderate to high caffeine levels while in the womb is linked to excess weight gain in early childhood, suggests a large observational study published in the online journal BMJ Open.

The findings, which back general advice to limit caffeine intake while pregnant, prompt the researchers to query whether mums-to-be should cut out the world’s most widely consumed central nervous system stimulant altogether.

Caffeine intake associated with reduced levels of erectile dysfunction

Houston: Men who drink the equivalent caffeine level of two to three cups of coffee a day are less likely to have erectile dysfunction (ED), according to researchers from The University of Texas Health Science Center at Houston (UTHealth). The results of a study published recently in PLOS ONE found that men who consumed between 85 and 170 milligrams of caffeine a day were 42 percent less likely to report ED, while those who drank between 171 and 303 milligrams of caffeine a day were 39 percent less likely to report ED compared to those who drank zero to seven milligrams a day. This trend was also true among overweight, obese and hypertensive men.

Acute poisoning from alcoholic energy drinks on the rise

Scimex: Australian sales of highly caffeinated energy drinks have steadily increased since they were introduced in the early 2000s, and these days are being mixed with alcohol to produce popular alcoholic energy drinks. Now, Australian experts have reported on the health risks associated with these drinks, and say that high-risk "binge" drinking and incidents of acute poisoning are on the rise.

Time to take a stand against the sale of caffeinated energy drinks

Deakin University. Australia: International health experts are calling on governments to take a stronger regulatory stand on the use of energy drinks and curb the growing harm caused by their consumption.

Research finds caffeine increases soft drink consumption

Deakin University Australia: Researchers from Deakin University's Centre for Physical Activity and Nutrition Research (C-PAN) have found that caffeine increases the consumption of soft drinks. In a study published in the British Journal of Nutrition, researchers measured the influence caffeine had on the consumption of sugar sweetened soft drinks. They found that people drinking caffeinated drinks consumed much more than those who drank the non-caffeinated equivalents.

Caffeine

• Caffeine occurs naturally in more t han 60 plants including coffee beans, tea leaves, kola nuts used to flavor soft drink colas, and cacao pods used to make chocolate products. 
• Man-made caffeine is sometimes added to foods, drinks, and medicines. 
• 90% of people in the world use caffeine in one form or another.
• The average american adult has an intake of 200 mg per day, the amount in two 5-ounce cups of coffee or four sodas. 
• Whether caffeine is consumed in food or as a medicine, it changes the way your brain and body work and changes how you behave and feel. 
• Caffeine is a central nervous system stimulant. Your central nervous system includes your brain, spinal cord, and the other nerves in your body. 
• Caffeine’s main effect on your body is to make you feel more awake and alert for a while, but it can also cause problems. 
• It can:

• Make you jittery and shaky
• Make it hard to fall asleep, stay asleep, or get a good night’s sleep
• Make your heart beat faster
• Cause an uneven heart rhythm
• Raise your blood pressure
• Cause headaches, nervousness, and/or dizziness 
• Make you dehydrated (dried out) especially after a workout
• Make you dependent on it so you need to take more of it

• Did You Know? Caffeine doesn’t make a drunk person sober or fit to drive – it DOES NOT get rid of the effects of alcohol. 
• Caffeine is both a drug and a food additive. 
• Caffeine is used in both prescription and over-the- counter medicines to treat tiredness or drowsiness and to improve the effect of some pain relievers. 
• HEART: People with heart problems shouldn’t use caffeine because it makes their hearts work too hard.
• ANXIETY: People with anxiety problems or panic attacks may find that caffeine makes them feel worse. 
• After drinking caffeine, it usually reaches its peak level in your blood within one hour and stays there for four to six hours. 
• Caffeine increases the release of acid in your stomach, sometimes leading to an upset stomach or "heartburn." 
• DEHYDRATION: Caffeine is a diuretic, meaning it makes your body lose more water. So, drinks that contain caffeine aren’t good for quenching your thirst. Whether you drink sodas or coffee with caffeine or use medicines with caffeine, take care to drink extra water when you are working out or in the heat so your body doesn’t get dehydrated (dried out). 
• PREGNANCY: Most experts feel that using small amounts of caffeine during pregnancy is safe, but larger amounts of caffeine can be harmful during pregnancy. Women who are pregnant or planning to get pregnant should speak with their doctor about using caffeine.  
• TOLERANCE: When people use caffeine every day, their bodies get used to it, and they don’t get the “good effects” of feeling more awake and able to concentrate unless they use more of it. This is called “tolerance.” 
• ADDICTION: Some studies show that caffeine causes a physical dependence or addiction. If a person gets withdrawal symptoms when they suddenly stop using caffeine, then the person has a physical dependence on caffeine. Withdrawal symptoms don’t feel good and can include: severe headaches, muscle aches, temporary feelings of depression, and irritability. When people experience these symptoms, they often just take in more caffeine to make them go away. This cycle is hard to break.
• OVERDOSE: Symptoms of caffeine overdose (for example with pure caffeine products) can include rapid or dangerously erratic heartbeat, seizures and death. Vomiting, diarrhea, stupor and disorientation are also symptoms of caffeine toxicity. These symptoms are likely to be much more severe than those resulting from drinking too much coffee, tea or other caffeinated beverages.
• DEATH? Caffeine overdose is dangerous and can kill you.
  FDA knows of a 19 year old college student who died after taking an overdose of caffeine tablets to stay awake. A caffeine tablet contains as much caffeine as one to three 5-ounce cups of coffee.The FDA is also aware of at least one death of a teenager who used powdered pure caffeine.
• WARNING. PURE CAFFEINE: Pure powdered caffeine is a powerful stimulant and very small amounts may cause accidental overdose. Parents should be aware that these products may be attractive to young people. These products are essentially 100 percent caffeine. A single teaspoon of pure caffeine is roughly equivalent to the amount in 25 cups of coffee.
• HOW MUCH? Experts agree that 4 to 7 cups of coffee or more each day is too much. Studies suggest that moderate amounts of caffeine are not harmful. How much is moderate? One hundred to 200 mg (one to two 5-ounce cups of coffee) each day is the limit that some doctors suggest, but each person is a little different. How caffeine affects people varies with their size, their sex, and how sensitive they are to caffeine’s effects. Experts agree that 600 mg (four to seven cups of coffee) of caffeine or more each day is too much. 
• BE INFORMED. Learn how much caffeine is in your foods and drinks. Check the Caffeine Content Table to see how much caffeine you take in each day. If you’re taking in too much caffeine, you may want to cut back. This isn’t easy – reduce your caffeine slowly to make withdr awal symptoms (like bad headaches, and feeling tired, and depressed) as mild as possible.
