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?

Elderly Drug Addicts

Americans aged 75-85 are some of the country's biggest drug addicts. That's right, 68% of surveyed adults who take prescription medications were found to also take over-the-counter medications and dietary supplements. The problem with this practice is that many drugs and supplements have adverse reactions with each other.

Here go some more elderly drug-abuse facts:

• more than half of U.S. adults aged 57 to 85 are using five or more prescription or non-prescription drugs
• one in 25 are taking them in combinations that could cause adverse drug reactions
• adults over 65 make up more than 175,000 emergency department visits a year for adverse drug reactions
• commonly prescribed drugs accounted for a third of these visits

Wow! Does anybody else find this scary? The reason for this inordinate drugging of our elderly citizens is simple: We live in a drug-worshiping culture. Our current medical paradigm is all about the drugs, man. Foolish, very foolish. Don't get me wrong, drugs are useful. I've said exactly that, here, and in my book. But why more than 50% of all people over 57 (that's too young, in my opinion) need to be on 5+ drugs is dumbfounding. Frankly, it blows my mind.

But, I get it; many others don't. You see, drugs are the main weapon in the arsenal of the current health care authority--the medicos. Drugs fit into the current "health" paradigm, which the medical education is based specifically around. Neither situation alone--the use of drugs to treat, or medical domination of the health care system--is necessarily a problem. It's the two together that cause a dangerous situation.

My answer to the problem:

1. Medicine stay the dominant force in health care, but alter their paradigm by adding health and wellness to a far greater degree than what they are doing now.
2. Recognize other health disciplines as allies in this quest to improve health care.
3. Take responsibility in determining all medications a patient is on and managing the patient accordingly.
4. Recognize that conservative, non-drug treatment is always, ALWAYS, superior to medicating when that option exists.
5. Understand when that option exists.

Until these simple steps are adopted by the medical industry, expect more of the same: Too many elderly people (and people, in general) addicted to prescription meds, and way too many people getting sick or dying from adverse drug reactions.

Oh the Irony...

The American Medical Association has said it wants fast-food restaurants to post nutritional facts on their menus as a means to combat obesity. These facts should include calories, grams of fat, grams of saturated fat, and grams of trans fat in each fast food item.

You probably already know how I feel about this notion if you've read my June 18th post, Barking up the Wrong Tree. Not only do I think it's ludicrous to penalize fast-food chains (what about pizza parlors, ice cream shops, candy stores, Chinese restaurants and burger stands, like Fat Burger and every other junk food supplier?), it ain't gonna do diddly if people don't value there health to begin with.

"No, you're wrong Campos. People will make better choices if they can see how many calories they're consuming." Poppycock! This information has been on food packaging for years at our country's biggest supplier of junk food - the good ol' fashioned grocery chain. That's right, the American institution known as the grocery store is the largest pusher of junk food in the world, and they've been advertising calories and fat counts for ever. It hasn't stopped people yet from stuffing their faces full of Dinty Moore Beef Stew. And neither will it help people choose between the Double Quarter Pounder and the MacSoy Melt.

I find it especially hysterical that the AMA is promoting this idea. Wait. I've got a better idea. Why don't fast-food restaurants include this information on the back of their receipts in technical language and with the smallest print the human eye can distinguish - just like they do with prescription medications? That'll at least put them up to par with the medical/pharmaceutical industries as responsible informers.

And here's another good idea: why not have medical offices post the number of deaths associated with adverse drug reactions (also see here) and unnecessary surgeries (and here, and here) in their waiting rooms so that people know just what they're in for. Think the AMA will push for that kind of responsible advertising anytime soon?
