o Causes short term memory loss and amnesia - Cassava- cyanide o If not properly prepared (out in the sun), it can be lethal - Licorice root o Contains glycyrrhizin which can rob body out of potassium which leads to paralysis - Comfrey tea o Contains pyrrolizidine alkaloids which can have a very negative effect on the liver Problems with body chemistry - Phenylketonurea (PKU) o Genetic conditions unable to metabolize phenylalanine (component of aspartame) o 1/20,000 o Detected early in life o Accumulates in brain which is problematic - Lactose intolerance o Can occur at any time in life o 70% of the world is lactose intolerant o Milk allergy is due to some protein in milk (antibodies that form in body in response to milk) o In lactose intolerance, enzyme lactase is missing (lactose = glucose + galactose) o No metabolizing, so lactose goes through and bacteria digests it, which produces gas and therefore bloating, and diarrhea o Produces methane gas and hydrogen gas Give patient known concentration of lactose Measure methane or hydrogen in breath
Ève Belzile-Dugas Winter 2015 o Limit intake of dairy products E.g. in yogurt, most of lactose is broken down during fermentation o Possible to consume enzyme orally (can tolerate acidity of stomach) or consume products without lactose - Fructose malabsorption o Fructose is half of sucrose molecule o Doesn’t get absorbed in blood stream through small intestine, goes through and is digested by bacteria o Similar symptoms to lactose intolerance o People realize they have it when they eat fruit - Favism/hemolytic anemia/glucose-6-phosphate dehydrogenase deficiency o Abnormal breakdown of red blood cells o Symptoms: fatigue, shortness of breath, headache, nausea, vomiting, fever o Takes year before the proper diagnosis is made o Pythagoras had this o Fava beans are difficult to digest for these people - Hereditary fructose intolerance o Genetic condition o The body can absorb the fructose but cannot process it properly o Fructose-1-phosphate aldolase deficiency o Fructose amounts build up, interferes with processing of glucose o Causes nausea, sweating, tremors, seizures (symptoms of hypoglycemia) o Strong aversion to sweet - Intolerances o Simple carbohydrates (e.g. sugar alcohols like lactitol, mannitol, glucitol used in gum because don’t cause cavities) Washed out from the body by diarrhea Sometimes used voluntarily to laxative properties - Celiac disease/gluten sensitivity o First described by Dr. Samuel Gee (1888): children with bloated stomachs, diarrhea, stunted growth o Dr. Willem K. Dicke (WWII): Germans cut food to Poland Patients suffering from celiac disease got better when supplies of wheat were cut off o Wheat contains a family of proteins, gluten Constituted of two basic proteins: Gliadin (real problem) Glutenin Found in wheat, barley, rye, spelt, kamut, oats
Ève Belzile-Dugas Winter 2015 o The immune system mistakes gliadin for an invader and mounts an antibody attack. This triggers the release of cytokines which damage the villi of the intestines where absorption of food occurs.
