Caffeine and Pregnancy: How much is too much
One of the first things most of us women prepare to say goodbye to once we see those two pink lines on our pregnancy tests is caffeine. Many women will stop their caffeine habit cold turkey out of the sheer fear of doing some sort of damage to the new life growing inside of them. These women will swear off anything that has caffeine in it from coffee, and soda to even chocolate. Then there are some of us who will still drink caffeine but cut back. Instead of drinking five cups of coffee a day, we might cut back to at least one cup of coffee to get us through the day.
Our mothers and grandmothers will probably tell us that they drank the same amount of caffeine pregnant as they did when they were not pregnant and their children turned out fine. However a lot more research has been done since their time and studies are showing that too much caffeine can cause some complications such as preterm labor and/or low birth weight.
So how much caffeine is too much caffeine? Doctors are telling their patients that a moderate amount of caffeine will not harm their babies. Even though caffeine does cross the placenta, anything less than 300 milligrams a day (an 8 ounce cup of strong coffee) will not do any harm. Anything over 300 milligrams puts your baby at risk and studies have also shown that women who drink more than 300 milligrams of caffeine a day during their first trimester have a slightly higher risk of a miscarriage.
Studies have also shown that women who had over 500 milligrams of caffeine a day had babies who had faster heart rates and faster breathing rates. These babies also spent more time awake in their first few days of life rather than peacefully sleeping after their long journey.
There are a number of other reasons why we women might want to cut back on the amount of caffeine we drink during pregnancy. For starters, it has no nutritional value. If there is ever a time for us to be aware of our nutritional needs it is when we are pregnant. Second, caffeine is a stimulant which will increase your heart rate and can cause insomnia and headaches which can put some stress on your growing little one. Third, caffeine can cause heartburn. If you have been pregnant before you know that heartburn can be a burden to begin with, and caffeine just makes it worse. Lastly it is a diuretic which means it can cause you to lose fluids which can put you at a risk of becoming dehydrated.
While it is not necessary for you to give up all caffeine through out the duration of your pregnancy, you should learn how to drink it in moderation or don’t drink it at all. If you can not handle having only one cup of coffee a day, then you might be better off drinking no coffee at all. Stick with caffeine free sodas and even decaf coffee. Remember though that decaf coffee still contains small traces of caffeine so make sure you take that into consideration.
Brazilian Superfruit Found to Kill Cancer Cells
A recently completed University of Florida study has added to the buzz surrounding the Brazilian acai berry. The study is one of the first to research the many claims attributed to the acai fruit.
In it’s study, six different chemical extracts were made from acai berry pulp, and each extract was prepared in seven concentrations.
At least 4 of the extracts killed a great many cancer cells when applied for 24 hours or more. Anywhere from 35 percent to 86 percent of the cancer cells were destroyed, depending on the particular extract and concentration.
According to Stephen Talcott, an assistant professor with UF’s Institute of Food and Agricultural Sciences, the study showed extracts from acai berries triggered a self-destruct response (apoptosis) in up to 86 percent of leukemia cells tested
Talcott, however, cautioned against reading too much into the results, noting that the tests were run against cancer cell cultures and not on human test subjects.
Still, the results are exciting. In the last year, the Brazilian berry has really taken off in the United States. It has also caught the attention of many companies who are now creating products that include the acai berry.
Although, acai berries are thought to be one of the richest fruit sources of antioxidants, other antioxidant rich fruits have been shown to kill cancer cells in similar studies.
Antioxidants are substances that may protect cells from the damage caused by unstable molecules known as free radicals. Free radical damage is theorized to be one of the main causes of cancer. A sufficient amount of antioxidants are thought by many to short-circuit this process by interacting with and stabilizing the free radicals and may stopping the damage that they do to healthy cells.
Experts are divided on just what effect antioxidants have on cancer cells in the human body, because of the many other lifestyle factors that have to be factored into the equation.
Many anecdotal claims have been made for the acai berry. And traditionally Indians in the Brazilian rain forest have used it in ways as diverse as food, house thatching, drink, diarrhea, jaundice, fevers, and as treatment for many other health diseases.
The University of Florida study is a welcome step towards getting away from some of the claims of acai and subjecting it to controlled studies.
“A lot of claims are being made, but most of them haven’t been tested scientifically,” Talcott said. “We are just beginning to understand the complexity of the acai berry and its health-promoting effects.”
Male Menopause? Not!
It’s hard to adjust to a world seemingly spinning out of control. Getting ahead in the “old” economy is getting harder and harder. There are limited resources for men who want to challenge the status quo, who want to break out from the “shoulds” that rule them, who are confused any more about what it means to “be a man.”
While the physiology of male menopause is a measurable fact, I think something else is going on here. After the initial years struggling to achieve their career aspirations and role as provider, men would do well in recognizing this shift as a desire for greater fulfillment beyond work. Women have fulfilled their role as child bearer and mother. We have no qualms in stating our needs once the kids are off pursuing independent lives.
Rat Race Running You Ragged?
Most men are probably wondering, “Where the hell do I fit in anymore?” Some men confuse wanting off the rat race roller coaster as the start of a midlife crisis. But a crisis, when confronted, is an opportunity. Someone once wrote, “confusion is the threshold of a greater awareness.” Most intelligent men understand this concept but tend to judge it. I’m here to tell you that confusion is a good thing!
Think for a moment about Chinese handcuffs; the harder you pull, the stronger they bind you. The same is true with confusion; if you fight the fact that you cannot control your confused state, you will continue to muddle along. Instead, consider the possibility that by adapting to a new and changing reality, clarity and direction are yours for the asking.
When we resist change, there is no space to move, to explore, to expand. Just because the competitive landscape has changed and relationships are often fraught with frustration does not diminish your role or importance. You have the potential to be at cause in your life.
Maybe it’s your turn to create, not compete. Give yourself permission to breathe.
