Grapefruit Derived Flavonoid Naringin Improves Ketoacidosis And Lipid Peroxidation In Type 1 Diabetes Rat Model

Abstract Hypoglycemic effects of grapefruit juice are well known but the effects of naringin, its main flavonoid on glucose intolerance and metabolic complications in type 1 diabetes are not known. Sprague-Dawley rats divided into 5 groups (n = 7) were orally treated daily with 3.0 ml/kg body weight (BW)/day of distilled water (group 1) or 50 mg/kg BW of naringin (groups 2 and 4, respectively). Groups 3, 4 and 5 were given a single intra-peritoneal injection of 60 mg/kg BW of streptozotocin to induce diabetes. Group 3 was further treated with subcutaneous insulin (4.0 IU/kg BW) twice daily, respectively. Stretozotocin (STZ) only-treated groups exhibited hyperglycemia, polydipsia, polyuria, weight loss, glucose intolerance, low fasting plasma insulin and reduced hepatic glycogen content compared to the control group. Furthermore they had significantly elevated Malondialdehyde (MDA), acetoacetate, β-hydroxybutyrate, anion gap and significantly reduced blood pH and plasma bicarbonate compared to the control group. Naringin treatment significantly improved Fasting Plasma Insulin (FPI), hepatic glycogen content, malondialdehyde, β-hydroxybutyrate, acetoacetate, bicarbonate, blood pH a Continue reading >>

    This topic is actually much simpler than it's made out to be, that being it is merely a question of quantity of ketone production, and is only an issue in an individual who is unable to produce insulin.
    Unfortunately this is often glossed over even in medical texts, so it's not uncommon for even doctors and nurses to misunderstand the simple yet crucial difference, not to mention nutritionists.
    In the end it's all a matter of volume. Kind of like the difference between a sip, a gulp, and drowning.
    A moderate carbohydrate diet will often result in occasional trace amounts of ketone levels in the blood, typically after a fast (first thing in the morning) or after a decent exercise session. A very low carbohydrate diet is ketogenic by nature due to both low levels of carbohydrates in circulation/storage and ingestion of high levels of fat, and will result in moderate levels of ketone bodies circulating, usually around quarter-to-half the concentration of blood glucose, but occasionally reaching or even exceeding parity.
    Proper starvation - as in complete caloric avoidance for a week or two - can result in ketone bodies up to double or even triple circulating glucose levels, but even then the body has plenty of feedback loops to maintain ketone levels that are still well within safe parameters, you'll do organ damage from other stressors before ketones become a problem. There is of course something called alcoholic ketoacidosis, but this requires extensive periods of time where near 100% of your calories are derived from ethanol.
    Point being, this has nothing to do with nutritional ketosis. If you are capable of producing insulin then there is no danger of acidosis, which is actually ridiculously elevated ketones AND glucose levels.
    Serum ketone body levels typically look like this:
    Normal diet: 0-0.1 mmol/L
    Normal diet overnight fasted: 0.1-0.5 mmol/L
    Ketogenic Diet: 0.6-3.0 mmol/L
    1-4 weeks starvation: 6-10 mmol/L
    Diabetic insulin deficiency: >20 mmol/L

    Ketoacidosis
    Nutritional ketosis is a normal, physiological response to carbohydrate and energy restriction. A ketogenic diet is an effective weight loss strategy for many. Ketoacidosis, on the other hand, is a pathological condition caused by insulin deficiency. The common theme is low insulin; however, in ketoacidosis, blood glucose levels are very high. Ketone levels are elevated in both states, although are 10-20x higher in ketoacidosis (~0.5-2 vs. > 20 mM). Nutritional ketosis and ketoacidosis should not be confused with one another, and a ketogenic diet doesn't cause ketoacidosis.
    ...
    In people on a ketogenic diet, blood glucose levels are not increased. This is an important aspect differentiating nutritional ketosis from ketoacidosis.
    ...
    Ketogenic dieting is safe, and can be beneficial. Ketoacidosis is pathological, and can be fatal.

    Diabetic Ketoacidosis vs. Dietary Ketosis
    Diabetic patients know that the detection in their urine of the ketone bodies is a danger signal that their diabetes is poorly controlled. Indeed, in severely uncontrolled diabetes, if the ketone bodies are produced in massive supranormal quantities, they are associated with ketoacidosis.
    ...
    However, during very low carbohydrate intake, the regulated and controlled production of ketone bodies causes a harmless physiological state known as dietary ketosis.

    IN A NUTSHELL: Nutritional ketosis is a state of health in which your body is efficiently burning fat as its primary fuel source instead of glucose. When undergoing a ketogenic diet you are essentially converting yourself from a “sugar burner” to a “fat burner”. This is accomplished by reducing your consumption of carbohydrates, increasing your intake of fat, and consuming only an adequate amount of protein to meet your body’s needs. Th ...

    Ketosis and ketoacidosis sound similar and are sometimes confused, but don’t mistake these conditions for one another. These involve two different sets of circumstances with considerably different outlooks. Both are triggered by an increase of ketones in the body, which are acids released into the bloodstream when the body burns fat for energy instead of carbohydrates. But it’s how the body responds to this increase that sets ketosis and keto ...

As a result, you gain excess weight, develop inflammation and become prone to cellular damage. To avoid this problem, ...
