KRON 4 | Smell Test to Detect Brain Disease

KRON 4 Smell Test 4

A simple smell test could provide a quick and inexpensive way to identify those at high risk for Alzheimer’s and Parkinson’s. Weekend anchor Marty Gonzalez on “KRON 4 Morning News Weekend” is a willing test subject for the Alzheimer’s peanut butter test.

KRON 4 Smell Test1

Worldwide, nearly 44 million people have Alzheimer’s disease or a related form or dementia, but only 1 in 4 people with the disease is diagnosed.

Smell Test Protocol

Testing for Alzheimer’s disease or other dementias can be time-consuming, costly and invasive. In contrast, this University of Florida study used a simple peanut butter test:

  1. Patient: Closed his/her eyes and mouth. Then blocked one nostril.
  2. Clinician: Opened the peanut butter container (one tablespoon).
  3. Clinician: Held the ruler next to the open nostril while the patient breathed normally.
  4. Clinician: Moved the peanut butter up the ruler one centimeter at a time during the patient’s exhale until the person could detect an odor.
  5. Clinician: Recorded the distance.
  6. After 90 seconds, the procedure was repeated on the other nostril.

Left-Right Asymmetry

  • peanut butter_dollarphotoclub_40526513_600x400The study revealed dramatic differences between the left and right nostril in patients with early stage Alzheimer’s disease.
  • In patients with other kinds of dementia, there were either no differences in odor detection between nostrils or the right nostril was worse at detecting odor than the left one.
  • When smelling the peanut butter, the left nostril in the Alzheimer’s patients could not detect the smell of the peanut butter until it was an average of 10 centimeters (about 4 inches) closer to the nose than the right nostril had detected the smell. *A normally functioning olfactory nerve can detect odors at about 20 centimeters (about 8 inches) from the test agent.

*  See your physician if you lose your sense of smell. *

Validated Five-Item Test for Dementia

orange-03_croppedIn University of Chicago Medical Center study, nearly 3,000 adults, aged 57 to 85, had to identify five odors (peppermint, fish, orange, rose, and leather). During a five-year follow-up, those that could not identify at least four out of the five odors were found to be more than twice as likely to develop dementia.

Sodium Benzoate | How to Prevent Aging and Cancer

Benzoates are widely used preservatives

Sodium benzoate (also known as E211) is a chemical preservative used to help inhibit the growth of bacteria and fungus in acidic products. It is linked to aging and cancer and is widely used in foods, beverages, cosmetic, dental care products, and pharmaceuticals that contain:

  • Vinegar (salad dressings, pickled foods)
  • Carbonic acid (carbonated drinks)
  • Citric acid (jams, fruit juices, cough syrups, baby wipes, liquid hand soaps)
  • Alcohol (alcohol-based mouthwash)
  • Other high acids (soy sauce, Chinese food sauces)

Manufactured from Crude Oil

Sodium benzoate is the sodium salt of benzoic acid. This crystalline powder is produced by reacting sodium hydroxide (lye) with benzoic acid.  Benzoic acid is commercially manufactured by reacting toluene with oxygen.  Toluene is:

  • Related to benzene (a carcinogenic substance).
  • Found in crude oil and used to make gasoline.
  • Also known as methylbenzene or phenylmethane.

Due to the unpleasant aftertaste of sodium benzoate and not so much for toxicity, sodium benzoate concentration is limited by the FDA in the U.S. and should not exceed 0.1% by weight.  Potassium benzoate, the potassium salt of benzoic acid, is an alternative preservative to sodium benzoate.  When lower sodium content is required, potassium benzoate is used in place of sodium benzoate.    Continue reading “Sodium Benzoate | How to Prevent Aging and Cancer”
