Aldosterone synthesis is stimulated by several factors:

With respect to the major nutrients in foods and beverages, carbohydrates have the most profound effect on blood glucose and insulin levels, however, protein and fats also have an effect.

But as most people with diabetes know – particularly those who monitor their blood glucose levels regularly – it’s not just the foods and beverages we eat that affect our blood glucose levels. For example, blood glucose levels are often highest in the morning after an overnight fast, and after exercising, our insulin requirements typically decrease. The reasons why are relatively complex, and require a little knowledge of the way our bodies work.

Let’s start with the pancreas. It’s a small tadpole-shaped organ located in the abdomen, tucked behind the stomach. It secretes digestive juices into our gut, which digest the proteins, fats and carbohydrates from foods and drinks into their components (amino acids, fatty acids and sugars, respectively) so that they can be absorbed into our bodies through our intestines. In addition, it releases (secretes) hormones into our blood stream that regulate blood glucose levels. The hormone insulin is secreted by beta-cells, and glucagon is secreted by α-cells that are clumped together in little islands (islets of Langerhans) in the pancreas.

Most insulin is secreted by the pancreas after a meal containing carbohydrate, but it is also released in small amounts in-between meals at what’s known as the basal rate. Interestingly, our brain and nervous system uses about 80 per cent of the glucose utilised by our whole body, but glucose uptake by our brain and nervous system is not regulated by insulin. Also, while insulin stimulates glucose uptake by our muscles, they have other glucose receptors that do not require insulin to work.

Insulin lowers blood glucose levels partly by suppressing the release of glucose from the liver, by increasing glycogen (a kind of starch) synthesis and storage, and by inhibiting glycogen breakdown and the formation of glucose from other sources such as glycerol (from fat), lactate (from the metabolism of fuels like glucose and fructose by the liver and muscles) and amino acids (from proteins) by the process known as gluconeogenesis. It also enhances the uptake of glucose and some amino acids by our muscles and increases protein synthesis. In fat cells, it stimulates the synthesis of fatty acids from other fuels (e.g. glucose and fructose), and prevents the breakdown of fats into fatty acids.

Glucagon is secreted by the pancreas when blood glucose levels start to go below optimal levels, such as after an overnight fast, or during periods of increased energy expenditure (e.g., when exercising), to sufficiently induce a rapid, yet transient, rise in blood glucose. Glucagon raises blood glucose levels by having essentially the opposite effects of insulin by promoting the production (gluconeogenesis) and release (glycogenolysis) of glucose from glycogen stores in the liver and muscles. In fat cells, glucagon causes the breakdown of fats into free fatty acids which are released into the circulation to provide another source of fuel for our bodies.

So, while the foods and drinks we consume have a significant effect on blood glucose levels, they are not the only factors that make our blood glucose go up and down.

Aldosterone affects the Diastolic Blood Pressure and often when systolic pressure is good (110-130) and diastolic pressure is low (below 70) it is caused by low aldosterone so this is also a measure of correct mineralcorticoids.
Fludrocortisone (Florinef) is started at a ¼ of a tab, as it is a very potent steroid and changes your body's fluid balance. Increasing to 1/2 tab after 7-10 days depending on reactions and severity of problems. It is raised in this manner, 1/4 tab at a time, until the BP is normal and low aldosterone symptoms disappear. If at any time BP goes too high it should be reduced.
It can also cause fluid retention and pressure headaches, so these are signs of too much, or possibly it is lowering potassium too much so this is why electrolytes need to be checked often as you adjust this.

The GI was introduced back in 1981 to rate the glycemic character of the carbohydrate in individual foods like bread, breakfast cereal, rice, pasta, apples etc. The purpose was to exchange one carbohydrate source with another in your meals and snacks (e.g. replacing a high GI breakfast cereal like corn flakes with a low one like natural muesli). The decision behind the cut-offs for rating high GI (70 or higher) and low GI (55 or less) foods, was based on the spread of GI values among the single foods that had been GI tested.

Increasingly we are asked about the GI of mixed meals and the effect of extra protein and fat in the food on GI and blood glucose response. Eaten alone, protein and fat have little effect on blood glucose levels, but that’s not to say they don’t affect your blood glucose response when they are combined with a carbohydrate-rich food. Protein will stimulate additional insulin secretion, resulting in lower blood glucose levels. Protein and fat both tend to delay stomach emptying, thereby slowing the rate at which carbohydrate can be digested and absorbed. So, a high fat meal will have a lower glycemic effect than a low fat meal even if they both contain the same amount and type of carbohydrate.

We believe there’s a real need to define the difference between a low GI diet and/or meal and a low GI food. Because a low GI food is defined as 55 or less, everyone has made the reasonable assumption that a whole diet that averages 55 or less is a low GI diet. In fact, the average Australian and American diets already have a GI of around 55–60 because we eat fruits and dairy foods which are naturally low GI. So, to reduce the risk of chronic disease, we believe we need to aim lower and suggest that 45 is a better cut-off point for a low GI diet.

Why 45? Well, we know from numerous around the world that the daily average GI of the diet of people in the lowest quintile (20% of the population) is about 40–50. Similarly, in a meta-analysis in of 15 experimental studies investigating the role of low GI diets in managing diabetes, the daily average GI was 45. Since this average GI has been proven to have significant health benefits in people with existing diabetes and in reducing the risk of chronic diseases like heart disease and diabetes, and importantly, people can and do achieve it in real life, we believe a GI of 45 or less is what we all need to be aiming for.”

The most reliable and most accurate way to test for adrenal fatigue is the 24 hour adrenal saliva test. This test will give you your cortisol levels either 4 or 6 times (depending on which lab) during the day and night. It is not only your cortisol levels that are important, but also the cortisol rhythm. You cannot get accurate saliva results while on any kind of medication or supplement that will affect cortisol. Examples of this would be (this is not a complete list) Hydrocortisone, anti-anxiety meds, some anti-depressants, herbal adrenals supplements, asthma inhalers, prednisone. Saliva testing tells you the level of cortisol that is free and available (unbound) for your body to use. Where a blood cortisol level tells you what is bound and unbound. It is the unbound cortisol that is we need to know about. Herbal support will either extend your natural production or will help to raise or lower a low or high level of cortisol. Due to the herbal remedies interference with your own cortisol production you cannot test while taking these.
