Food-Healthy or Not?

Having had a weight problem on and off for most of my life, I look at food as both an enemy and a friend. I have a love-hate relationship with food, and realize the impact is has on me, not only physically, but mentally. Food can get to the point of running (or ruining) your life...can you go to the Christmas party or your friend's house and have dinner? Will there be healthy food? If not, will everyone think you are snotty for not eating? Will they snicker, will they laugh?

The American diet for the most part is pathetic. Processed food, chemicals, irradiation, vitamins, pills, supplements, organic, or not...the list never ends. And that is just the beginning. Part of the problem with healthy eating is it costs more than cheap, processed food. Organic strawberries-$6.00, 8 processed hot dogs-$0.79, healthy food at a decent cost-priceless. Americans are bigger, unhealthier, and seemingly lazier than ever before.

I used to weigh 240 pounds and worked very hard to lose it. I tried many diets, fasts, pills, counting calories, counting fat, counting every ounce of food that entered my body. I became obsessed. I worked at a forklift factory doing security in a plant that had 3 forklift scales that I would weigh on every hour and average my weight. Every hour, eight hours a day, forty hours a week. Could I leave work thinner than when I got there? How much water could I drink to make that happen? What if I ate just fruit or negative calorie food? How many miles could I walk in an eight hour shift? One, two, four, ten?

The only thing that has ever really worked for me is counting fat grams. Nothing else. Eating a diet that did not have a lot of meat, a lot of veggies and fruit, and drinking a lot of water seemed to be the way to go. I would eat around 17 grams of fat a day, but sometimes consume 1500-1800 calories and the weight fell off.

After a few years though I became very ill with an autoimmune disease similar to lupus. At first the doctors thought I was allergic to something I was eating. Start with the basics-red dye, shellfish, nuts, dairy, strawberries, tomatoes, gluten, who knows? I lived on lamb and rice for six weeks trying to isolate the problem. I started to think everything I ate, everything that I absorbed through my skin was causing me to be sick. I was sick for almost four years before anyone had a clue what was wrong.

I once went to a naturopath/chiropractor who told me I needed to eat for my blood type, O-. My blood type begged for meat, especially red meat, and lots of it. I never was a huge fan of meat, but I figured what the heck, I'll try anything. Up until that point I had eaten mostly lacto-ovatarian and felt fine. Eating for my blood type removed my gall bladder, with a doctor's assistance. After I started eating so much meat, I felt awful. How anyone can do the Atkins diet is beyond me.

Overall, I believe a healthy diet consists of a lot of fresh vegetables and fresh fruit, not a great deal of meat (I don't know the last time someone in the US died from a protein deficiency), whole grains, and water-about a gallon a day. Not that I don't like Pepsi and pizza as much as the next person, but I do know what I feel better and healthier eating.

Lab Exercise-Drug Recognition Evaluation

I am a police officer and Drug Recognition Expert and specialize in drug impaired driving. The drug impaired driving program classifies 7 different categories of drugs based on their psychological and physiological effects on the body. A full drug evaluation is a process which includes a series of questions, blood pressure, pulse, temperature, divided attention tests, eye examinations, and toxicology by way of blood or urine.

There are seven categories of drugs that we consider for impairment. The drug symptomatology (and their exceptions) is categorized on a matrix card for quick reference. A much more intensive list of signs and symptoms are also utilized. Although each person is different, the majority of the time, drugs act a certain way upon the human body, both psychologically and physiologically.

The primary tasks for a Drug Recognition Expert are to determine driving impairment above and beyond alcohol impairment, if alcohol only is impairing the person, if the person has a medical condition or injury causing the impairment, or if the person is not impaired at all.

A drug evaluation consists of questions asked of the subject about what they have had to eat or drink in the past 24 hrs, physical disabilities and impairments, medication and drug usage, and sleeping habits. We also ask the subject if they know the approximate time without looking at a watch or clock. These questions assist in determining impairment factors, but also give us a chance to evaluate a persons speech patterns, body language, environmental interactions, and internal body clock.

Regardless of whether or not alcohol is suspected for the impairment, I request a breath sample showing the breath alcohol content from a deep lung breath from the subject. I can use an instrument calibrated to obtain and process breath alcohol.

After the series of questions and breath sample, I request the subject perform a Standardized Field Sobriety test called Horizontal Gaze Nystagmus (HGN.) Nystagmus is an involuntary jerking of the eyeball which is not normally visible to the naked eye. However, certain drugs enhance nystagmus to the point where it is visible. Central nervous system (CNS) depressants (including alcohol), inhalants, and dissociative anesthetics (such as PCP) enhance nystagmus. There are other types of nystagmus, but for law enforcement purposes, I look for nystagmus resulting from drug use or a recent head injury. While having the subject perform this test, I look for equality in pupil size, the nystagmus itself, and how the person balances and follows instructions.

The subject also performs divided attention tests such as the Walk and Turn, One Leg Stand, Rhomberg Balance, and the Finger to Nose test.

After completion of the divided attention tests, eye examinations are completed in which the subject's pupil size is measured in room light, near total darkness (NTD), and direct light. The pupil size is documented as normal, dilated, or constricted. During the direct light examination, the reaction to light (RTL) of the pupil is checked for normal reaction, slow reaction, or little to no reaction to the light stimulus.

Constricted Pupil

Pulse is checked 3 times during the examination and blood pressure once. Temperature is also taken during the evaluation. Once the evaluation is completed in its entirety, a blood or urine sample is obtained from the subject to identify the drugs used.

1) For the purposes of this lab experiment, I am taking the information from anonymous individuals that are under the influence of either a CNS stimulant drug, cannabis, or a narcotic analgesic, and testing whether or not the human physiological reactions fall into drug symptomatolgy categories for the certain drugs. I placed evaluations in 3 piles and mixed them up and randomly chose 1 test subject from each drug category. I will test the following aspects of the drug evaluation:

• Blood Pressure-normal 120/80
  
• Pulse rate- normal (for DRE purposes) 60-90 bpm
  
• Temperature-normal 98.6 plus or minus 1 degree
• Pupil Size-normal: room light 2.5-5.0mm, NTD 5.0-8.5mm, direct light 2.0-4.5mm
  
• Pupillary Reaction to Light-normal, slow, or little to none
  

The common symptoms for the 3 categories are as follows:

CNS Stimulants:

• BP-elevated
  
• Pulse-elevated
  
• Temperature-elevated
  
• Pupil size-dilated
  
• RTL-slow

Cannabis:

• BP-elevated
• Pulse-elevated
  
• Temperature-normal
• Pupil size-dilated
• RTL-normal

Narcotic Analgesics:

• BP-below normal
• Pulse-below normal
  
• Temperature-below normal
• Pupil size-constricted
• RTL-little to none

All subjects reflected in this are anonymous and the information has been utilized in part from previous drug evaluations. The toxicology has been confirmed by an accredited lab.

2) Hypothesis:

I expect that a person psychoactively under the influence of the either a CNS stimulant, cannabis, or a narcotic analgesic will exhibit symptoms common with that drug category symptomatology.

Subject 1, 21 year old male: CNS Stimulant

• BP-140/100
  
• Pulse-114, 120, 106 bpm
  
• Temperature-100.2
  
• Pupil size- room light-7.5mm, NTD-8.5mm, direct light-7.0mm
  
• RTL-slow
  

Subject 2, 35 year old female: Cannabis

• BP-150/90
• Pulse-96, 100, 88 bpm
  
• Temperature-99.0
• Pupil size-room light-7.0mm, NTD-9.0mm, direct light-5.5mm
• RTL-normal

Subject 3, 55 year old male: Narcotic analgesics

• BP-100/60
• Pulse-54, 58, 52 bpm
  
• Temperature-96.2
• Pupil size-room light-3.0mm, NTD-3.5mm, direct light-3.0mm
• RTL-Little to none visible

3) For DRE evaluations I used the following equipment:

• Sphygmomometer (manual, not electric)
• Stethoscope
• Thermometer and sheath
• Nitrile gloves
• Pupil light
• Red glow stick stimulus (for pupil test)
• Pupillometer
• Watch

5) The different measurements reflected on the DRE evaluations support the hypothesis. For each drug category, the measurements are accurate for the drug symptoms. A couple anomalies in the data in that the subject under the influence of a CNS stimulant had pupils of 8.5mm in NTD. That is the normal range, but in the high end. However, for DRE purposes, the totality of the pupils show a consistent dilation, which is how the documentation would occur. The other anomaly is the subject under the influence of cannabis had one pulse at 88 bpm which is in the normal range, rather than elevated. Again, the other 2 are elevated which would categorize as a whole as elevated.

6) One of the problems with the technique I chose is picking only one evaluation for each category, instead of more than one, which may have reflected less consistency with the drug symptoms. Also, polydrug use is a factor with drug evaluations and trying to find single category drug use is difficult.

7) Overall, the drug symptomatology for each of the 3 categories; CNS stimulants, cannabis, and narcotic analgesics are consistent with what the subjects exhibited during their DRE evaluations.
