Diet and Exercise Better than Smart Drugs

Some people are driven by their bodies, and others by their mind. Despite the age-old argument of whether the two entities are separate and distinct, we know one thing for sure--working out the body does wonders for mental health. Take that, Descartes!

A recent study out of Duke University showed that regular moderate exercise and healthy diet together can improve scores on cognition tests. The four-month study conducted by Duke's nueropsychology department looked at 124 fifty-two year old men and women with high blood pressure (HBP) who were a minimum of 15 pounds overweight, on average. The study was originally designed to look at diet, exercise, and HBP; but the researchers decided to throw in cognitive function as an interesting side investigation.

One third of the participants followed the DASH--Dietary Approaches to Stop Hypertension--diet, which emphasizes low-fat dairy products, fruits and vegetables, in combination with regular exercise. One third, followed the DASH diet along with a weight-management program and aerobic exercise. The final third went about on their regular dietary and exercise regimens.

The exercise conducted was moderate--30 minutes three to four times a week, "enough to put the heart up to 75 to 80 percent of its maximum rate," as one of the researchers said. The weight-management programs were split between two strategies--one centered on reducing portion size and cutting the snacking habit, while the other focused on appetite awareness training, which provided guidelines on food quantity (how much one ate) as well as food quality (types of food). The cognitive tests focused on executive function, learning and psychomotor speed.

Researchers found that the group that exercised regularly and ate well had an overall 30 percent improvement in mental function by the end of the four-month period. They also lost an average of 19 pounds and lowered systolic blood pressure (the higher of the 120/80 reading) by 16 points and diastolic pressure by 10 points. Shazam! All by diet and exercise.

As one of the researchers concluded, “There are neurochemical changes that happen with exercise. There is increased production of brain-derived neurotrophic factor, which stimulates connection with other brain cells, but also there is some evidence that it helps grow new brain cells.”

On top of that, as I point out in my book, The Six Keys to Optimal Health, regular exercise increases circulation, oxygen and nutrient transport to the brain; it reduces depression and anxiety; and it leads to increased production of phenylethylamine (PEA), which is the body's natural opiates...so it FEELS GOOD! Oh yeah, give it to me, baby!

There you have it: Another study showing the enormous benefits of diet and exercise. Now, before you say, "Big deal, tell me something I don't know," understand that these finding should shed some light on the notion of mass use of nootropic drugs, otherwise known as smart drugs. When 7% of all college students and 20% of polled scientists using them to enhance memory, problem solving, attention, and mental endurance, I think it's time to start discussing alternatives.

No drugs are free of side effects, and the notion of the world's scientists being tweaked out on designer speed is, well....scary (think Norman Osbourne). So that's why I post these seemingly obvious studies. Yes, we all know that diet and exercise have wide-ranging benefits. But then why isn't everybody doing them?

Stress in Pregnancy Doesn't Increase Complications

Preeclampsia and gestational hypertension are two disorders taken very seriously during pregnancy. Both disorders can lead to and might even cause the death of the unborn fetus. Many women who suffer from these maladies blame themselves and their stress levels; they think that if they just weren't as stressed-out during their pregnancies, they could have probably prevented the disorders and the subsequent deaths. A recent study, however, shows otherwise.

Dutch researchers have found that a woman's stress levels during pregnancy do not increase the chance of developing either of the hypertensive disorders of pregnancy. Although increased psychological stress is not great during pregnancy--it can wear a woman down and lead to postpartum depression--expecting mothers should not fear getting preeclampsia or gestational hypertension.

Preeclampsia is a hypertensive condition with significant protein concentrations found in the urine (proteinuria). Gestational hypertension is preeclampsia without proteinuria. Hypertension is high blood pressure (HBP), and elevated blood pressure can force substances, like protein, through the kidneys and into the urine--not a good situation. Obviously, HBP can be dangerous for a developing fetus. Both hypertensive disorders are asymptomatic--that is, they have no outstanding symptoms leading to their discovery. Therefore, blood pressure must be checked regularly during pregnancy. Both hypertensive disorders can develop after 20 weeks of pregnancy, but preeclampsia is often seen after week 32. The only solution to this dangerous situation is emergency cesarean section, induced labor, or abortion. Because of the high risk to mother and fetus, one of the above options must be exercised.

I found this an important piece to do since so many pregnant women in America seem to be stressed out. According to another recent study, 20% of all new mothers in the U.S. suffer from postpartum depression. Postpartum depression is linked to many risk factors including tobacco use late in pregnancy, physical abuse before or during pregnancy, partner-related stress during pregnancy, trauma during pregnancy, and financial stress.

Hey, life can be tough. And it's hell of a lot harder to deal with when feeling big, bloated, uncomfortable, hormonal and unable to find a comfortable position to sleep in. I get it. I see my wife dealing with it now during our second pregnancy. It ain't all fun and games. But at least when times get real tough, and the stress seems to know no bounds, please rest assured that you can "feel crazy" and not worry that you're damaging your baby--at least not as far as it's blood supply is concerned. Any other hypothesis regarding Mama's stress stressing baby out is still up for analysis. But for preeclampsia--not a chance.

Stress Management Chills Hypertension

High stress leads to high blood pressure. You don't say.

Stressed out? Boiling mad? About to lose your lid? Chill out, man...relax. Really, it'll save your life if you do.

Stress management techniques have been shown to reduce hypertension, or high blood pressure (HBP), if learned and practiced regularly. And even more exciting is that reducing stress through effective techniques can reduce the need for blood pressure drugs in elderly people with a special type of HBP called isolated systolic hypertension. Nice. So says a study out of Massachusetts General Hospital in Boston.

High blood pressure, not a disease in itself, but a warning that disease is looming, can lead to such maladies as heart attacks, stroke and kidney failure. Dang--doesn't it make sense to learn a few stress reduction techniques? I think so. Here are the best:

• Creating mental balance through a special technique called the collapse process (ask me about it, I'll be glad to explain).
• Meditation (there are many techniques to choose from--all good in my opinion)
• Pranayama (yogic breathing technique)
• Working out (especially hitting the heavy bag)
• Sex

That's right--learning a few of these powerful techniques can add years to your life by preventing some of today's most prevalent disorders. And in the case of isolated systolic hypertension, which often afflicts the elderly and is hard to treat with medications, these findings are stupendous.

So don't delay. Learn some stress management techniques today and you'll find life a little easier to deal with.
