How Sugar Damages Cells and Causes Diabetes

Sunday, December 18th, 2011

Problems associated with higher-than-desired sugar levels are myriad.  Most stem from the central problem of excess glucose flooding into blood vessel cells.

Everyone with glucose-handling difficulties is at increased risk of developing life-threathening conditions ranging from heart disease and stroke to blindness, nerve damage, depression, and kidney disease.  These dire complications are the result of hyperglycemia (excess glucose in the bloodstream).  There is now evidence that those with high “normal” fasting glucose levels suffer a greater incidence of disorders that are associated with diabetic conditions.

An increasing number of scientific studies reveal that sugar toxicity is a causative factor in a host of degenerative diseases and premature aging.  One only has to look at the multiple diseases suffered by diabetes to appreciate the lethal effects of protein glycation and carbonylation, major complications related to excess sugar (glucose) levels.  Non-diabetes also encourter destructive protein-damaging glycation and carbonylation processes, albeit at a lower rate than diabetes.

Taking steps to guard against glycation would appear to be a mandatory part of a health maintenance program.

Avoid food cooked at high temperatures to reduce the formation of AGEs (Advanced Glycation Ends) in the body.

[AGEs are the end-products of glycation reactions, in which a sugar molecule bonds to either a protein or lipid molecule without an enzyme to control the reaction].

In pre-diabetes, a patient’s blood glucose levels are abnormally evalated, but often not enough to warrant diagnosis of type II diabetes early on. Most pre-diabetic patients experience few if any symptoms, and thus have no idea that they are at risk of developing diabetes.  That is why it is so important to guard against sugar toxicity before a diabetic state manifests.  See the symptoms below.

There are good sugars and bad sugars.

Bad sugars, often referred to as simple sugars, are those in foods that do not offer any other nutritional benefit. Examples of simple sugars include foods like soda, sweets, sugar cereals, juice drinks, and refined grains.

Good sugars, or complex carbohydrates, are present in foods that provide nutrients such as vitamins, minerals, protein, and fibre. Examples of complex carbohydrates include foods like fruit, vegetables, beans, and whole grains.

Careful monitoring of your weight and your food choices will help you prevent diabetes.

Focus on lean proteins at each meal, and restrict your sugar and starch intake.  You also need to choose fibre-rich whole grains to release glucose in a steady stream to moderate blood sugar levels.  Good food choices include:

  • Dietary fibres
  • Eggs
  • Flaxseed oil
  • Lamb
  • Lean Beef
  • Low-fat Cottage Cheese
  • Nuts and Seeds (raw: almonds, sesame seeds, hazelnuts, cashews)
  • Poultry
  • Soy products
  • Cold-water fish
  • Veal
  • Yoghut

An accurate measurement of underlying glucose impairment is the hemoglobin A1C blood test.  But be on the look out for these symptoms:

  • Blurred vision
  • Excessive thirst
  • Extreme hunger
  • Increased urination
  • Increased fatigue
  • Irritability
  • Numbness/tingling in fingers and toes
  • Weakness or fatigue
  • Weight gain.

The key to living a long life unemcumbered by disease is to identify aging parts of your body that may be experiencing decline before disease strikes and take action immediately to treat them.  This can be accomplished by comprehensive annual check-ups that include advanced screening methods and thorough blood testing.

By taking action early, utilizing an integrative program of healthy diet, targeted nutrients, bioidentical hormones, and nutritional supplementation, you can ensure a bright healthy future free from silent diseases that rob aging adults of their helpful vigor.

Combating Age-Related Brain Deterioration

Monday, December 5th, 2011

By Eric R. Braverman, MD with Dale Kiefer, BS – Life Extension

 

You probably won’t hear this from your doctor, but your brain’s gradually shrinking as you read this.

Why?

A certain amount of physical wasting or atrophy – also medically termed “regional deterioration of brain structure” – occurs in the brain naturally with age.  The impact of these structural alterations is vastly underestimated by both physicians and patients alike.  This process usually commences around age 30, with marked acceleration observed at 50.

The results of physical brain deterioration can be dramatic. They include neurocognitive deficits, such as diminished attention span, verbal skills, spatial perception, deficits in abstract thinking and creativity, along with increased difficulty learning new tasks and retaining new information, flagging memory, and deteriorating sleep quality.

Maintaining a youthful brain in the face of these detriments of aging is perhaps the most crucial challenge of aging. The brain, our most important organ, is responsible for orchestrating a complex symphony of hormonal, neurochemical, and electrical signals to maintain the body in a state of vibrant health.

In this blog, we summarize what you can do to assist brain health and help preserve cognitive function.

  • Your brain begins to structurally deteriorate as early as age 30.
  • Maintaining youthful cognitive function is a crucial challenge of aging.
  • Declining memory function may also begin as early as age 30 and is often evident after 50 years of age.
  • Fortunately, it is possible to take proactive steps to maintain youthful cognition with aging.
  • Maintaining a healthy body weight and body fat percentage may help preserve healthy brain structure and function.
  • Frail bones have been linked with cognitive decline in women.
  • Hormonal balance may promote healthy cognitive function.
  • Traumatic brain injury is a common yet overlooked cause of cognitive difficulties.
  • Exercise increases blood flow to the brain and may decrease the risk of cognitive decline, while promoting sleep.
  • Strong mucles = strong brain.  Studies have repeatedly shown that older individuals who exercise regularly and maintain a healthy weight are less likely to succumb to cognitive decline.  Shrinking muscle mass correlates with declining cerebral blood flow.
  • A healthy diet and extra nutritional support further enhance cognitive function.
