Diabetes - 0 views

    Insulin is a hormone produced by the pancreas to control blood sugar. Diabetes can be caused by too little insulin, resistance to insulin, or both. To understand diabetes, it is important to first understand the normal process by which food is broken down and used by the body for energy. Several things happen when food is digested: A sugar called glucose enters the bloodstream. Glucose is a source of fuel for the body. An organ called the pancreas makes insulin. The role of insulin is to move glucose from the bloodstream into muscle, fat, and liver cells, where it can be used as fuel. People with diabetes have high blood sugar because their body cannot move sugar into fat, liver, and muscle cells to be stored for energy. This is because either: Their pancreas does not make enough insulin Their cells do not respond to insulin normally Both of the above There are two major types of diabetes. The causes and risk factors are different for each type: Type 1 diabetes can occur at any age, but it is most often diagnosed in children, teens, or young adults. In this disease, the body makes little or no insulin. Daily injections of insulin are needed. The exact cause is unknown. Type 2 diabetes makes up most diabetes cases. It most often occurs in adulthood. However, because of high obesity rates, teens and young adults are now being diagnosed with it. Many people with type 2 diabetes do not know they have it. Gestational diabetes is high blood sugar that develops at any time during pregnancy in a woman who does not have diabetes. Diabetes affects more than 20 million Americans. Over 40 million Americans have pre-diabetes (which often comes before type 2 diabetes).

Zinc and diabetes--clinical links and molecul... [J Nutr Biochem. 2009] - PubMed - NCBI - 0 views

  • Zinc supplementation of animals and humans has been shown to ameliorate glycemic control in type 1 and 2 diabetes, the two major forms of diabetes mellitus, but the underlying molecular mechanisms have only slowly been elucidated. Zinc seems to exert insulin-like effects by supporting the signal transduction of insulin and by reducing the production of cytokines, which lead to beta-cell death during the inflammatory process in the pancreas in the course of the disease
  •  
    Zn show to help in glycemic control in both type I and II diabetics.  It appears to do this through inflammation reduction and thus improved insulin/Receptor signal transduction.   Also of note, antibodies against Zn transporter have been found in type I DM.

  • the energy supplied to rephosphorylate adenosine diphosphate (ADP) to adenosine triphosphate (ATP) during and following intense exercise is largely dependent on the amount of phosphocreatine (PCr) stored in the muscle
  • Creatine is chemically known as a non-protein nitrogen
  • It is synthesized in the liver and pancreas from the amino acids arginine, glycine, and methionine
  • ...26 more annotations...
  • Approximately 95% of the body's creatine is stored in skeletal muscle
  • About two thirds of the creatine found in skeletal muscle is stored as phosphocreatine (PCr) while the remaining amount of creatine is stored as free creatine
  • The body breaks down about 1 – 2% of the creatine pool per day (about 1–2 grams/day) into creatinine in the skeletal muscle
  • The magnitude of the increase in skeletal muscle creatine content is important because studies have reported performance changes to be correlated to this increase
  • "loading" protocol. This protocol is characterized by ingesting approximately 0.3 grams/kg/day of CM for 5 – 7 days (e.g., ≃5 grams taken four times per day) and 3–5 grams/day thereafter [18,22]. Research has shown a 10–40% increase in muscle creatine and PCr stores using this protocol
  • Additional research has reported that the loading protocol may only need to be 2–3 days in length to be beneficial, particularly if the ingestion coincides with protein and/or carbohydrate
  • A few studies have reported protocols with no loading period to be sufficient for increasing muscle creatine (3 g/d for 28 days)
  • Cycling protocols involve the consumption of "loading" doses for 3–5 days every 3 to 4 weeks
  • Most of these forms of creatine have been reported to be no better than traditional CM in terms of increasing strength or performance
  • Recent studies do suggest, however, that adding β-alanine to CM may produce greater effects than CM alone
  • These investigations indicate that the combination may have greater effects on strength, lean mass, and body fat percentage; in addition to delaying neuromuscular fatigue
  • creatine phosphate has been reported to be as effective as CM at improving LBM and strength
  • Green et al. [24] reported that adding 93 g of carbohydrate to 5 g of CM increased total muscle creatine by 60%
  • Steenge et al. [23] reported that adding 47 g of carbohydrate and 50 g of protein to CM was as effective at promoting muscle retention of creatine as adding 96 g of carbohydrate.
  • It appears that combining CM with carbohydrate or carbohydrate and protein produces optimal results
  • Studies suggest that increasing skeletal muscle creatine uptake may enhance the benefits of training
  • Nearly 70% of these studies have reported a significant improvement in exercise capacity,
  • Long-term CM supplementation appears to enhance the overall quality of training, leading to 5 to 15% greater gains in strength and performance
  • Nearly all studies indicate that "proper" CM supplementation increases body mass by about 1 to 2 kg in the first week of loading
  • short-term adaptations reported from CM supplementation include increased cycling power, total work performed on the bench press and jump squat, as well as improved sport performance in sprinting, swimming, and soccer
  • Long-term adaptations when combining CM supplementation with training include increased muscle creatine and PCr content, lean body mass, strength, sprint performance, power, rate of force development, and muscle diameter
  • subjects taking CM typically gain about twice as much body mass and/or fat free mass (i.e., an extra 2 to 4 pounds of muscle mass during 4 to 12 weeks of training) than subjects taking a placebo
  • The gains in muscle mass appear to be a result of an improved ability to perform high-intensity exercise via increased PCr availability and enhanced ATP synthesis, thereby enabling an athlete to train harder
  • there is no evidence to support the notion that normal creatine intakes (< 25 g/d) in healthy adults cause renal dysfunction
  • no long-term side effects have been observed in athletes (up to 5 years),
  • One cohort of patients taking 1.5 – 3 grams/day of CM has been monitored since 1981 with no significant side effects
  •  
    Nice review of the data, up to the publication date, on creatine.

  •  
    pancreatic cancer survival risk is shorted by 2.43 with elevated estradiol in women.  This risk is linked to an increase in TNF alpha.  In contrast, men survival risk was worse by 1.96 odds ratio with low Testosterone.  Again, inflammation was the culprit.

Nutritional Modulation of Insulin Resistance - 0 views

  • Five branched chain and aromatic amino acids (isoleucine, leucine, valine, tyrosine, and phenylalanine) showed significant associations with future diabetes
  • there is increasing evidence that longer term high-protein intake may have detrimental effects on insulin resistance [68, 117–123], diabetes risk [69], and the risk of developing cardiovascular disease
  • high-protein and the high GI diets significantly increased markers of low-grade inflammation
  • ...5 more annotations...
  • significant and clinically relevant worsening of insulin sensitivity with an isoenergetic plant-based high-protein diet
  • healthy humans that are exposed to amino acid infusions rapidly develop insulin resistance
  • longer term high-protein intake has been shown to result in whole-body insulin resistance [68, 118], associated with upregulation of factors involved in the mammalian target of rapamycin (mTOR)/S6K1 signalling pathway [68], increased stimulation of glucagon and insulin within the endocrine pancreas, high glycogen turnover [118] and stimulation of gluconeogenesis [68, 118].
  • it was recently shown in a large prospective cohort with 10 years followup that consuming 5% of energy from both animal and total protein at the expense of carbohydrates or fat increases diabetes risk by as much as 30% [69]. This reinforces the theory that high-protein diets can have adverse effects on glucose metabolism.
  • Another recent study showed that low-carbohydrate high-protein diets, used on a regular basis and without consideration of the nature of carbohydrates or the source of proteins, are also associated with increased risk of cardiovascular disease [70], thereby indicating a potential link between high-protein Western diets, T2DM, and cardiovascular risk.
