The Role Of Insulin In The Body
Tweet Insulin is a hormone which plays a key role in the regulation of blood glucose levels. A lack of insulin, or an inability to adequately respond to insulin, can each lead to the development of the symptoms of diabetes. In addition to its role in controlling blood sugar levels, insulin is also involved in the storage of fat. Insulin is a hormone which plays a number of roles in the body’s metabolism. Insulin regulates how the body uses and stores glucose and fat. Many of the body’s cells rely on insulin to take glucose from the blood for energy. Insulin and blood glucose levels Insulin helps control blood glucose levels by signaling the liver and muscle and fat cells to take in glucose from the blood. Insulin therefore helps cells to take in glucose to be used for energy. If the body has sufficient energy, insulin signals the liver to take up glucose and store it as glycogen. The liver can store up to around 5% of its mass as glycogen. Some cells in the body can take glucose from the blood without insulin, but most cells do require insulin to be present. Insulin and type 1 diabetes In type 1 diabetes, the body produces insufficient insulin to regulate blood glucose levels. Without the presence of insulin, many of the body’s cells cannot take glucose from the blood and therefore the body uses other sources of energy. Ketones are produced by the liver as an alternative source of energy, however, high levels of the ketones can lead to a dangerous condition called ketoacidosis. People with type 1 diabetes will need to inject insulin to compensate for their body’s lack of insulin. Insulin and type 2 diabetes Type 2 diabetes is characterised by the body not responding effectively to insulin. This is termed insulin resistance. As a result the body is less able to t Continue reading >>
How Do Fats & Proteins Affect Blood Sugar Levels?
After you eat, your blood sugar levels increase and trigger the release of insulin, an important hormone in managing how your body uses glucose. Different types of nutrients affect blood sugar differently, and maintaining an appropriate intake of carbohydrates, proteins and fats will help control blood sugar levels and prevent or manage metabolic diseases like Type 2 diabetes. Carbohydrates, proteins and fats are the three macronutrients your body needs. Carbohydrates are primarily used for energy, while proteins are important for rebuilding tissue, and fats are important for maintaining cell membranes and facilitating vitamin absorption, among other functions. Carbohydrates have the most significant impact on blood sugar, so carbohydrate intake should be monitored closely by individuals with or at risk for Type 2 diabetes. Protein's Effects on Blood Sugar Compared to carbohydrates, protein keeps blood sugar levels steady. When consumed alone, protein does not generate a rise in blood sugar. According to a study published in 2003 in “American Society for Clinical Nutrition,” individuals with Type 2 diabetes who maintained a 30:40:30 intake ratio of protein to carbohydrates to fat showed a 40 percent lower blood sugar response than those who maintained a 15:55:30 intake ratio. This suggests that protein is neutral food for blood sugar levels and can replace at least some carbohydrates to yield a better overall blood sugar response. Fat's Effects on Blood Sugar Like protein, fat has significantly less impact on blood sugar than carbohydrates. When consumed alone, ingested fats have no bearing on the concentration of circulating blood sugar. Replacing some carbohydrate content with healthy dietary fats could therefore result in steadier overall levels of blood sugar. M Continue reading >>
How Does Insulin Lower Blood Sugar?
Everyone knows that glucose, or sugar, is needed to give the human body energy. That would not be possible without the intervention of the hormone insulin -- a protein produced by the pancreas that responds to sugar levels in the blood. Pancreatic cells take up blood sugar and secrete insulin into the bloodstream. The insulin allows other body organs -- including the brain, liver, heart and muscles -- to take up sugar to fuel their own energy requirements. Video of the Day Insulin is made and released by a type of cell in the pancreas known as a beta cell. This process is complex and occurs in response to changes in glucose concentration in the blood. Glucose concentration is affected by a person’s nutritional status, for example, if the person just ate a full meal or has been fasting for several hours. It is also influenced by hormones released by the intestines that are involved in the digestion of what has been eaten. Further, the brain releases factors into the blood based on its energy status and requirements. A cascade of events begins when a person has eaten something, for example, a piece of bread. Bread is rich in carbohydrates, which when broken down by digestion become the sugar glucose. Glucose is absorbed by the intestines into the bloodstream, raising the blood glucose level, and transported to the pancreatic beta cells. Here it is broken down further into energy known as ATP, and this causes insulin to be released into the blood. Insulin then interacts with the body’s cells and organs, prompting them to absorb glucose from the blood to make their own energy. For example, the heart muscle needs glucose to make energy to sustain its pumping action. Decreasing Blood Sugar This movement of glucose into the body's cells lowers the levels of sugar in the bl Continue reading >>
Homeostasis - Blood Sugar And Temperature
Your body is made up of millions of cells which need the conditions inside your body to be as constant as possible so they can work properly. However everything you do tends to change your internal conditions. You take millions of new molecules into your body when you eat and digest food. Your blood sugar levels soar after you have a meal - but your cells use up the glucose fast when you exercise hard. You release heat energy every time you move about, the amount of water you take into and lose from your body varies all the time and your cells are constantly producing poisonous waste (see Homeostasis - the kidneys and water balance.) The blood sugar levels in your body are coordinated by hormones, chemicals which regulate and balance the working of organs and cells. Hormones are made in endocrine glands and are carried around the body to their target organs in the blood stream. Some hormones have long term effects, for example, the hormones that control how you grow and the changes that happen at puberty. Other hormones have shorter term effects. The hormones insulin and glucagon which control your blood sugar levels are like this. It is important that the core temperature of your body stays within a very small range for the enzymes in the cells of your body to work properly. Your skin is one of the most important organs in the control of body temperature.

Apple Cider Vinegar And Diabetes
OK, y’all. I wrote about this several years ago, but now I’m serious. If you want to control any type of diabetes better, consume vinegar before meals and at bedtime. Start today! It lowers post-meal and fasting glucose levels. In a study from Arizona State University, subjects took a drink of 20 grams of apple cider vinegar, 40 grams of water, and 1 teaspoon of saccharin with each meal. (I think stevia might be better than saccharin.) Those with insulin resistance who drank the vinegar had 34% lower postprandial (after-meal) glucose compared to controls. These postprandial benefits had been found before. It was thought that vinegar might slow the absorption of carbohydrate into the blood, or slow the breakdown of starches into sugars. This effect would mimic the effect of drugs like acarbose (brand name Precose). But the 2004 study cited above reported that vinegar reduced postprandial glucose more in subjects who were highly insulin resistant. The authors say this result shows that vinegar increases insulin sensitivity, perhaps acting similarly to metformin. Now studies have found that vinegar at bedtime reduces fasting blood glucose in the morning, indicating that vinegar might promote insulin production, like nateglinide (Starlix). Pretty amazing that a simple chemical like vinegar (acetic acid) could have the benefits of three different classes of diabetes drugs, and all for a few cents a dose! It’s likely good for both Type 2 and Type 1, especially for lowering postprandial glucose. And postprandial glucose levels account for 30% to 70% of A1C values. Vinegar has got to be the most cost-effective medicine in history, but most people with diabetes still aren’t taking it. And doctors aren’t prescribing it. Why not? Is it because there are no “vinegar rep Continue reading >>
Exactly What I Ate To Get My Blood Sugar Under Control For Good
When Thomas Rupp was diagnosed with type 2 diabetes, he was stunned. Despite having a challenging career (he was working in corporate finance and for FEMA), he managed to exercise regularly, and he rarely ate fast food or sweets. Sure, he weighed 245 pounds, but at 6 feet tall that didn't seem so terrible. He didn't consider that his weight pushed his BMI into the obese category—and he didn't realize that many of the "healthy" foods he was eating were actually loaded with tons of sugar and calories. Rupp's doctor started him on four different medications. The side effects were bothersome, but what really kicked him into gear was learning that he'd need to start injecting himself with insulin nightly. Instead, he turned to the Diabetes Reversal Program at Tufts Medical Center, where he met with the founding director, Michael Dansinger, MD. They worked together to closely examine Rupp's diet and uncover pitfalls that Rupp had trouble spotting on his own. (You can control your blood sugar with food and without insulin by making healthy lifestyle changes. Try the easy plan in The Natural Way To Beat Diabetes.) For instance, while adding some cream and sugar to a cup of coffee might not be a big deal for some people, Rupp often downed 10 cups of coffee a day to power himself through long days in the office. (Here are 8 physical signs you drink way too much coffee.) And he was putting cream and sugar in each cup. "That's 10 containers of cream and 10 teaspoons of sugar a day I was adding to my diet," he says. And even though he worked out, "I was drinking green juices at the gym, or protein smoothies with mango, once again without realizing the sugar content." Other seemingly healthy choices—like salads—also concealed stealth sugar bombs. "I would add vinaigrette dressi Continue reading >>
The 4 Foods That Will Steady Your Blood Sugar
Wondering what blood sugar has to do with you, if you don’t have diabetes? Keeping your blood sugar levels as steady as possiblenow may help you avoid getting diabetes later. “As you get older, your risk for type 2 diabetes goes up,” says Alissa Rumsey, Registered Dietitian and Spokesperson for the Academy of Nutrition and Dietetics. “Since you can’t modify your age, it is important to take other steps to lower your risk, including maintaining a healthy weight, getting enough exercise, and balancing your diet to prevent spikes in blood sugar.” Controlling your blood sugar will also just make you feel better. “It’s best to control blood sugar—it keeps your energy stable,” says Leann Olansky, M.D., an endocrinologist at the Cleveland Clinic. “If your blood sugar doesn’t vary that much before and after a meal, that’s a healthier way to be.” Unrelated to diabetes, symptoms of occasional high blood sugar aren’t life-threatening, but rather unpleasant and only potentially dangerous if you suffer from other health problems. “When your blood sugar is too high, it can make you feel sluggish,” says Dr. Olansky. “When it’s higher still, it can lead to dehydration and make your blood pressure unstable, and cause you to urinate more often, especially at night.” But when your blood sugar remains chronically high, insulin, a hormone that’s supposed to help your body store sugar as energy, stops working as it should. “Prolonged high blood sugar levels can lead to insulin resistance, meaning your body isn’t able to use insulin properly,” says Rumsey. “Over time this insulin resistance can develop into diabetes, when insulin isn’t able to keep your blood sugar within normal levels.” Current research reveals an association between spik Continue reading >>
Normal Regulation Of Blood Glucose
The human body wants blood glucose (blood sugar) maintained in a very narrow range. Insulin and glucagon are the hormones which make this happen. Both insulin and glucagon are secreted from the pancreas, and thus are referred to as pancreatic endocrine hormones. The picture on the left shows the intimate relationship both insulin and glucagon have to each other. Note that the pancreas serves as the central player in this scheme. It is the production of insulin and glucagon by the pancreas which ultimately determines if a patient has diabetes, hypoglycemia, or some other sugar problem. In this Article Insulin Basics: How Insulin Helps Control Blood Glucose Levels Insulin and glucagon are hormones secreted by islet cells within the pancreas. They are both secreted in response to blood sugar levels, but in opposite fashion! Insulin is normally secreted by the beta cells (a type of islet cell) of the pancreas. The stimulus for insulin secretion is a HIGH blood glucose...it's as simple as that! Although there is always a low level of insulin secreted by the pancreas, the amount secreted into the blood increases as the blood glucose rises. Similarly, as blood glucose falls, the amount of insulin secreted by the pancreatic islets goes down. As can be seen in the picture, insulin has an effect on a number of cells, including muscle, red blood cells, and fat cells. In response to insulin, these cells absorb glucose out of the blood, having the net effect of lowering the high blood glucose levels into the normal range. Glucagon is secreted by the alpha cells of the pancreatic islets in much the same manner as insulin...except in the opposite direction. If blood glucose is high, then no glucagon is secreted. When blood glucose goes LOW, however, (such as between meals, and during Continue reading >>

The main sugar found in the blood and the body's main source of energy. Also called blood sugar. PubMed Health Glossary (Source: NIH - National Institute of Diabetes and Digestive and Kidney Diseases) How the Body Controls Blood Glucose When the blood sugar levels rise, for instance following a meal, the pancreas releases insulin. Insulin enters the bloodstream and ensures that the sugar in the food and drinks we consume is transported from our blood to our cells, where it is transformed into energy for the body. Insulin also causes the liver and the muscles to store sugar, and stops new sugar being made in the liver. The blood sugar levels fall because of this. When blood sugar levels are low, the pancreas releases glucagon into the bloodstream. This hormone causes the cells of the liver to release stored sugar. Glucagon also ensures that the cells of the liver produce new sugar from other substances in the body. When the blood sugar level has risen, the release of glucagon is stopped once again.

Proven Tips & Strategies To Bring High Blood Sugar Down (quickly)
Untreated, high blood sugar can cause many problems and future complications. Recognizing signs of high blood sugar levels and knowing how to lower them can help you prevent these complications and increase the quality and length of your life. Topics covered (click to jump to specific section) High blood sugar level symptoms and signs Symptoms of high blood sugar include: Increased thirst Tired all the time Irritability Increased hunger Urinating a lot Dry mouth Blurred vision Severe high blood sugar can lead to nausea and fruity smelling breath The signs and symptoms for high blood sugar are the same for both type 1 and type 2. Signs usually show up quicker in those who have type 1 because of the nature of their diabetes. Type 1 is an autoimmune disease that causes the body to stop making insulin altogether. Type 2 is caused by lifestyle factors when the body eventually stops responding to insulin, which causes the sugar to increase slowly. People with type 2 can live longer without any symptoms creeping because their body is still making enough insulin to help control it a little bit. What causes the blood sugar levels go to high? Our bodies need sugar to make energy for the cells. Without it, we cannot do basic functions. When we eat foods with glucose, insulin pairs with it to allow it to enter into the cell wall. If the insulin is not there, then the glucose molecule can’t get through the wall and cannot be used. The extra glucose hangs out in the bloodstream which is literally high blood sugar. The lack of insulin can be caused by two different things. First, you can have decreased insulin resistance which means that your insulin doesn’t react the way that it is supposed to. It doesn’t partner with glucose to be used as fuel. Secondly, you can have no insuli Continue reading >>
The Ultimate Guide To Biohacking Your Blood Sugar Levels (and Why Sugar Sometimes Isn’t Bad).
If you enjoy the post you’re about to read, you may want to check out the free Diabetes Summit from April 18-25, 2016, in which 30+ experts (including me) share the best tips, strategies and secrets for controlling and reversing blood sugar issues, type 2 diabetes, pre-diabetes and metabolic syndrome… In one of my Quick & Dirty Tips articles last week, I mentioned that one “hack” I use to avoid experiencing big spikes in blood sugar from a big meal is to do some basic strength training with a dumbbell prior to eating that meal, which, as I explain in that article, activates specific sugar transporters responsible for taking up carbohydrate into muscle tissue, rather than partitioning those sugars into storage fat. Since my own personal genetic testing has revealed that I have a higher than normal risk for Type 2 diabetes (there are specific genetic variations associated with diabetes that you can check out here), hacking blood sugar levels to get them lower is a topic near and dear to my heart. This should also be a very important topic for you to educate yourself on, since not only are there are specific genetic variations associated with diabetes that you can check out here), hacking blood sugar levels to get them lower is a topic near and dear to my heart. This should also be a very important topic for you to educate yourself on, since not only are Type 2 diabetes rates rising, both in the United States and globally (even among athletes and so-called “healthy” people), but so are a host of other chronic disease, neural degradation and weight issues directly related to high blood sugar. Characterized by insulin resistance and chronic high blood sugar levels (hyperglycemia), type 2 diabetes can lead to both brain and metabolic dysfunction, and is also a sig Continue reading >>
Is Taking Insulin Daily For Type-2 Diabetes Fine? Is There A Possibility To Control Blood Sugar Using Oral Medicines?

Why Is This Generation More Prone To Diabetes, High Blood Pressure, And Other Health Issues? How Did Our Forefathers Deal With It?
When you leave your doctor’s office, do you ever wonder what he’s not telling you? Every appointment, he tells you to eat less sugar and go on more walks, but aren’t there other ways to get your diabetes under control? Here’s 3 tricks to manage your diabetes that your doctor won’t tell you: Eat More Fat You read that right. Eat more fat. That’s because fat helps your body absorb insulin. That means the more fat you eat, the easier it’ll be to manage your blood sugar. But here’s the kicker: It’s got to be the right type of fat. You’re looking for Unsaturated Omega-3 Fat. Here’s some great sources: Fish Eggs (Any eggs labeled “enriched” have plenty of omega-3) Grass-fed beef (There’s lots of omega-3 in the grass) Do Some Pushups… Or any kind of strength exercises. All the cardio your doctor tells you to do will increase your insulin absorption a little, but to really keep your body regulated you’ve got to get your entire body moving. The best way to do that is any exercise that focuses on strength. You want to avoid straining yourself, but make a habit of doing a few pushups every day, throw in some body squats, and soon you’ll be taking tighter control of your blood sugar. Not to mention it’ll get rid of stress, and give you plenty of energy. Relax Laying back and keeping cool are vital to regulating your blood sugar. Stress causes physical distress on the body which affects blood glucose levels. Not to mention, when you’re stressed out it’s easy to overeat, which obviously wreaks havoc on your blood sugar. For easy relaxation, try out simple meditation or breathing exercises. These tricks will help, but… If You Want to REVERSE your Type 2 Diabetes and never worry about your blood sugar again, here’s what you need: A recent med Continue reading >>
3 Easy Tips To Lower Blood Sugar Fast
Jeanette Terry was diagnosed with type 1 diabetes when she was 11 years old, and she has since lived with diabetes through difficult life transitions, including the teenage years, college, and having children. She addresses the day-to-day struggles of living with diabetes—going beyond medical advice—to improve overall adherence and management. Extremely high blood sugar levels can be dangerous, and they can cause lasting health complications. Remember: if you ever have blood sugar readings that remain high for more than 24 hours without coming down (and after an effort has been made to lower them), you need to be addressed by a doctor. That being said, we've all had those days when we get a random high blood sugar reading and we are not sure what caused it…or we forget to give insulin, or we eat a delicious dessert without realizing how much sugar is actually in it. For whatever reason, those out of the ordinary high blood sugar readings happen and need to be treated. No need to rush to the doctor for every high blood sugar reading though. There are some simple steps you can take to lower blood sugar fast. Watch for signs of high blood sugar You know the feeling: extreme thirst, sluggishness, nausea, blurred vision, a downright sick feeling. And your family or friends may tell you that extreme irritability is a major sign you need to check your blood sugar to see if it is high. The best thing to do is to catch it before it gets really high, or it will be harder to bring down quickly, causing havoc on your blood sugar readings for days. If you do not take insulin as a part of your treatment plan, these tips will show you how to lower your blood sugar fast. If you take insulin, you will first want to give the appropriate amount of insulin to correct the blood sugar. Continue reading >>
Which Supplements Can Help Lower Or Control My Blood Sugar?
Question: Answer: Many different supplements may help lower or control blood sugar in people with prediabetes or type 2 diabetes who experience hyperglycemia (when blood glucose rises higher than normal). These supplements are discussed below. More details about each, including dosage, drug interactions, potential side effects, and ConsumerLab.com's reviews of products on the market, can be found by clicking on the links. Due to the seriousness of hyperglycemia, it is important to consult with your physician regarding use of these supplements. Cinnamon supplements may modestly improve blood sugar in people with type 2 diabetes whose blood sugar is not well controlled with medication. In addition, one small study found that a branded cinnamon extract reduced fasting blood sugar by an average of about 10 mg/dL in prediabetic men and women with metabolic syndrome. Keep in mind, however, that only certain varieties of cinnamon have been shown to have this effect, and long-term safety studies have not been conducted. Curcumin (from turmeric) may improve blood sugar levels, according to preliminary studies, and one study found curcumin to dramatically lower the chances of prediabetes in middle-aged, slightly overweight men and women with somewhat higher than normal blood sugar levels. Alpha lipoic acid may improve insulin sensitivity and blood sugar control in people with type 2 diabetes, although it may only slightly reduce levels of glycosylated hemoglobin (HbA1c). Chromium picolinate may help some people with type 2 diabetes decrease fasting blood glucose levels as well as levels of insulin and glycosylated hemoglobin (HbA1c). However, be aware that high doses may worsen insulin sensitivity in healthy people who are not obese or diabetic. Having adequate blood levels of vi Continue reading >>
