Blood sugar

Maintaining normal blood sugar values is very important to overall health. Normal blood sugars are between eighty and one hundred twenty milligrams per deciliter. A blood sugar of seventy milligrams per deciliter will have a person feeling extremely hungry. Under seventy is considered hypoglycemia meaning low blood sugar.

The main hormones that regulate blood sugar are insulin and glucagon. These are produced by the pancreas. Insulin allows sugar to pass from the bloodstream into muscles lowering blood sugar. Glucagon breaks down glycogen stores, releases glucose from the liver, and fatty acids from fat tissue to liberate sugar into the blood. Insulin is in response to rising blood glucose values and glucagon in response to low blood glucose.  Insulin is produced by beta cells of islets of Langerhans and glucagon by alpha cells of the pancreas. Glucagon injections are available for people susceptible to hypoglycemia.

Diabetes mellitus is characterized by hyperglycemia. Type 1 or juvenile onset is characterized by lack of adequate insulin production.  Type 2 is called adult onset and caused by insulin resistance at the receptor level.  Hormones have receptors where the hormone binds to trigger its regulatory effect. Type1 is treated by insulin therapy, glucose monitoring, exercise, and proper nutrition program. Type 2 diabetes is treated with oral medication like Glucophage that helps lower sugar by increasing insulin sensitivity, exercise, glucose monitoring, and proper nutrition program.

Uncontrolled or untreated diabetes mellitus can cause a large variety of damage to the body. Complications include heart disease or stroke, kidney disease, eye damage, nerve damage, and erectile dysfunction. Symptoms include bowel and bladder distress, hearing impairment, dry or damaged skin, periodontal disease, dry mouth, excessive thirst, frequent urination, and neuropathy. In the treatment of this disease many will also experience hypoglycemia. Hypoglycemia may demonstrate the symptoms of confusion, excessive sweating, excessive hunger, fainting, fatigue, lightheadedness, shakiness, anxiety, headache, blurred vision, irritability, pallor palpitations, slurred speech, tremor, sleepiness, and unsteadiness. Prolonged or extreme low sugar may lead to comma or death.

The remainder of this document will discuss foods that  will   have  a positive effect on mental processes, diseases, and health.   This is a review of some foods that have  a  positive  effect on mental health and cognitive processes.

Diets

The word diet is where some problems begin. Normal metabolisms can make healthy nutrition programs reasonably easy to calculate. One problem with the word diet is that it insinuates that the client will be deprived of calories or nutrients. Although changes must be made, individuals have converted meals   from two to four per day and never felt severely deprived, shaky, sick, or like they have the flu while reaching body fat or weight goals. Another problem with the word diet is that ninety percent of known diet programs are not particularly successful after a one-year time frame. Nine out of eleven top listed diets are not proven successful after one year according to market research. The reason for this is generally because of severe deprivation of calories or specific macronutrients that may benefit metabolism very short term, but not long term and may detrimental. The keys to healthy nutrition programs are appropriate daily caloric intake, percentages of macronutrients, and   foo

TPN questions 2

What makes this program better than the rest? Everyone can reach a goal weight or body fat and maintain it.  TPN is tailored.   The categories designed make programs tailored to very specific needs of the client. TPN is precise.   It allows the clients to achieve a very targeted body weight or fat percentage. Many programs are far from tailored and far from healthy.  Many systems are nothing more than a lesson in portion control. A retired former professional football player should not be selecting from the same meals and eating the same number as his female counterpart.  He lost 32 pounds, but still looks quite round.  Did he lose muscle or fat? I know these two people should not be using the same caloric breakdown.  "The meals show up at the door and I eat them “Sounds awful.  Who wants to eat like that?    TPN provides numerous meal plans. We believe in eating fresh, less processed food as possible. We wish to empower people to a lifetime of nutrition management.  The goal
