Some herbal diabetes products have turned out to be downright dangerous. In February 2000, the FDA recalled five Chinese herbal products after discovering that they contained various amounts of two prescription diabetes drugs, phenformin and glyburide. (The products are listed at Phenformin was withdrawn from the U.S. market 20 years ago after it caused serious side effects, including several deaths.
A major feature of the disease is a condition known as insulin resistance.  Insulin is a hormone that moves glucose (sugar), from the bloodstream into the body’s cells where it is used for energy.  For a variety of reasons that are not fully understood, the body’s tissues don’t respond adequately to insulin and glucose then becomes elevated in the bloodstream.
Herbal prescriptions for diabetes are formulated or prescribed based on the patient’s predominant symptoms. For instance, a patient presenting primarily with excessive thirst (lung Yin deficiency) might be given a single herb, such as radix panacis quinquefolii; or a combination of herbs in a patent formulation such as yu chuan wan, which is used in general to treat diabetes of mild to moderate severity and specifically to treat excessive thirst due to Yin deficiency,12 and ba wei di huang tang (“eight-ingredient pill with rehmannia”), which was originally used to treat people exhibiting weakness, fatigue, and copious urine soon after drinking water.13
The study, published in Diabetes Care, measured C-peptide, which is produced at the same time and in the same quantities as the insulin that regulates our blood sugar. By measuring C-peptide levels in blood or in urine, scientists can tell how much insulin a person is producing themselves, even if they are taking insulin injections as treatment. The team studied 1,549 people with Type 1 diabetes from Exeter, England and Tayside, Scotland in the UNITED study.
As of this writing, new and exciting research is being done to prevent and cure Diabetes. JDRF Australia is working on a cure that aims to allow the body to produce insulin and for the body to stop attacking its own B-cells. Another cure that is being worked on is enhancing the survival of B-cells so that they can be transplanted to diagnosed patients. In terms of prevention, since testing can now be done for an individual’s genetic risk, diet modifications have been found to delay the onset of diabetes to at least five years.
Healthy fats: Medium-chained fatty acids found in coconut and red palm oil can help balance blood sugar levels, and they serve as the preferred fuel source for your body rather than sugar. Using coconut milk, ghee and grass-fed butter can also help balance out your blood sugar levels, so include these foods into your meals and smoothies. Some research actually suggests that a high-fat, low carb diet known as the keto diet may be a novel approach to reverse diabetes naturally, although you don’t technically have to go into ketosis to achieve the benefits of healthy fats in treating diabetes.

Magnesium deficiency is common in diabetic patients, as magnesium can be lost in the urine with hyperglycemia. A study in Diabetes Care reported that low magnesium status is common in Type 2 Diabetes Mellitus (T2DM) and showed that when low-magnesium Type 2 Diabetes Mellitus patients were given an oral dose of magnesium daily for sixteen weeks, the mineral reduced insulin resistance, fasting glucose, and A1C levels.

Several prediabetes interventions exist based on evidence from the landmark Diabetes Prevention Program (DPP) study. The DPP study reported that moderate weight loss (5-7% of body weight, or ~10-15 lbs. for someone weighing 200 lbs.), counseling, and education on healthy eating and behavior reduced the risk of developing type 2 diabetes by 58%. Data presented at the ADA 2014 conference showed that after 15 years of follow-up of the DPP study groups, the results were still encouraging: 27% of those in the original lifestyle group had a significant reduction in type 2 diabetes progression compared to the control group.
The findings, reported in the journal Cell Metabolism, show the cells grown in the lab can reduce blood glucose levels to normal. Professor Evans added: “It was a little bit of a surprise to see that beta cells produce a high level of this regulator, but beta cells have to release massive amounts of insulin quickly to control sugar levels. It’s a very energy-intensive process.”

What are the symptoms of prediabetes? People typically do not have symptoms of prediabetes, which is partially why up to 90% of people don’t know they have it. The ADA reports that some people with prediabetes may develop symptoms of type 2 diabetes, though even many people diagnosed with type 2 diabetes show little or no symptoms initially at diagnosis.
Magnesium is high in green leafy vegetables, nuts, beans, and grains, but we remove most beans and all grains from the diet of patients, which is why using magnesium as part of a natural remedy for diabetes can be beneficial. Low intracellular magnesium can cause insulin resistance. Dosing of up to 500 mg a day is fine, but higher than that may result in diarrhea in patients.
Change in fasting plasma glucose (A), 2 h post-oral glucose tolerance test (B), and homeostasis model assessment (HOMA-B) insulin secretion (C) during the 16-year follow-up in the Whitehall II study. Of the 6,538 people studied, diabetes developed in 505. Time 0 was taken as the diagnosis of diabetes or as the end of follow-up for those remaining normoglycemic.

They also have to balance the food they eat with the amount of insulin they take and their activity level. That's because eating some foods will cause blood sugar levels to go up more than others, whereas insulin and exercise will make blood sugar go down. How much the blood sugar level goes up after eating depends on the type of nutrients the food contains.

So if you really want to prevent diabetes, boost your vitamin D levels with either daily sunshine or quality vitamin D3 supplements. Vitamin D deficiency explains why diabetes is so rampant among African Americans, by the way. Did you notice that doctors don't explain any of this to African American patients? It's the dirty little racist secret of both the diabetes and cancer industries...
You should have no more than three of these “feeding times” per day. The reason limiting the number and duration of your meal times is so important has to do with staying out of the vicious cycle of increasing insulin resistance. To get smart on insulin resistance — the cause of both type 2 diabetes and obesity — read Dr. Jason Fung’s book, The Obesity Code: Unlocking the Secrets of Weight Loss, or watch his free lecture on YouTube.
