Sweet Potatoes and Yams
Despite their name, sweet potatoes (Ipomoea batatas) are not actually potatoes! In fact, they are only distantly related to potatoes. Sweet potatoes are technically roots and are dicots (two seed leaves), where as potatoes are tubers. Sweet potatoes can be white, yellow, orange, red, brown or purple in color. Their origin is thought to be in Central or South America. By the time Christopher Columbus arrived in 1492, Native Americans had begun to cultivate sweet potatoes.
Yams are moncots (one seed leaf) and are related to grasses and lilies. They contain more starch, less sugar and are drier than sweet potatoes and must becooked prior to eating. Yams are actually native to Africa and Asia. In the South, African slaves called the sweet potato "nyami" because it looked similar to another starchy tuber from their homeland. "Nyami" eventually became "yam". Additionally, "yam" also refers to sweet potatoes that are grown in Louisiana. Louisiana sweet potato growers wanted to distinguish their orange, sweet and soft sweet potato from the drier, white and yellow sweet potatoes grown in other parts of the country.

Hormone Highlight: Glucagon
AKA: Glucose Raiser
Location: Secreted by the alpha cells of the islet of Langerhans in the pancreas
Function(s): Glucagon is released by the pancreas when blood glucose levels are too low. Along with insulin, it is part of a 'feedback' system to keep blood glucose levels stable. The release of glucagon is triggered by elevated amounts of amino acids (organic compounds that form proteins) in the blood stream and by exercise. Injectable glucagon can be used to quickly raised blood glucose when blood glucose levels are severely low. Glucagon also stimulates the breakdown of glycogen (stored glucose in the liver and muscles.)

Ketosis vs Ketoacidosis: Part 1
| Although Ketosis and Ketoacidosis sound the same, these two metabolic processes are very different. Both conditions involve ketone bodies (ketones), acid compounds (acetoacetate, beta-hydroxybutyrate and acetone) that are created (ketogenesis) when fatty acids are broken down by the liver. The body will use ketone bodies for energy when glucose is not readily available.
Ketosis: In ketosis, elevated levels of ketone bodies are present in the blood stream (whereas ketonuria is the presence of keton bodies in urine.) Normal serum reference ranges for ketone bodies are 0.05-0.30 mmol/L, which is commonly seen after a meal or with an overnight fast. A ketogenic diet has levels of ketone bodies between 1.0-5.0 mmol/L. In normal, othewise healthy individuals, ketosis due to starvation or carbohydrate restriction is regulated via metabolism and hormones to prevent an over production of acid, which results in ketoacidosis.
Ketoacidosis: In ketoacidosis (also referred to as Diabetic Ketoacidosis), blood glucose levels are usually greater than 300mg/dL, while ketone bodies are greater than 25 mmol/L. Ketoacidosis is much more prevelant in Type 1 diabetics, as they do not produce any insulin to move glucose into cells and muscles. While rare, it is not impossible for a Type 2 diabetic to have ketoacidosis, which may occur in the presence of severe illness. Alcoholic ketoacidosis occurs with excessive alcohol use (heavy drinking on a daily basis) in malnourished persons. Signs of ketoacidosis include: thirst, frequent urination, high blood glucose levels, high presence of ketones in the urine, nausea, vomiting, abdominal pain, fruity smelling breath, fatigue/lethargy, or confusion.
Stay tuned in January for Part 2 when we'll discuss a ketogenic diet!

Low-carbohydrate pizza crusts
For a special treat, homemade pizza crusts are a great way to enjoy a slice of pie without overdoing it on the carbohydrates.
