Risk factors for type 2 diabetes include obesity, high cholesterol, high blood pressure, and physical inactivity. The risk of developing type 2 diabetes also increases as people grow older. People who are over 40 and overweight are more likely to develop type 2 diabetes, although the incidence of this type of diabetes in adolescents is growing. Diabetes is more common among Native Americans, African Americans, Hispanic Americans and Asian Americans/Pacific Islanders. Also, people who develop diabetes while pregnant (a condition called gestational diabetes) are more likely to develop type 2 diabetes later in life.
Type 2 diabetes is almost always reversible and this is almost ridiculously easy to prove. This is great news for the more than 50% of American adults who have been diagnosed with pre-diabetes or diabetes. Recognizing this truth is the crucial first step in reversing your diabetes or pre-diabetes. Actually, it something that most people already instinctively recognized to be true.
Imagine our bodies to be a sugar bowl. A bowl of sugar. When we are young, our sugar bowl is empty. Over decades, we eat too much of the wrong things – sugary cereals, desserts and white bread. The sugar bowl gradually fills up with sugar until completely full. The next time you eat, sugar comes into the body, but the bowl is full, so it spills out into the blood.
If you eliminate concentrated sources of carbohydrates (foods that turn into sugar in your blood stream) like candy and cookies, you may be able to reduce or eliminate the need for diabetes medications. Everyone with type 2 diabetes will benefit from an improved diet, but you may still need other interventions, such as increased physical activity, weight loss or medications to keep your blood sugars in the target range. Check with your doctor about any diabetes medication dose adjustments that may be required if you change your diet.
A healthy diet for prediabetes does not necessarily need to be low in carbohydrates. According to U.S. News and World Report rankings, the two types of diet for prediabetes and high cholesterol in 2018 are moderate diet patterns. A Mediterranean diet pattern is ranked first, followed closely by the Dietary Approaches to Stop Hypertension, or DASH, diet.
Interventional studies showed that high carbohydrate and high monounsaturated fat diets improve insulin sensitivity, whereas glucose disposal dietary measures comprise the first line intervention for control of dyslipidemia in diabetic patients.78 Several dietary interventional studies recommended nutrition therapy and lifestyle changes as the initial treatment for dyslipidemia.79,80 Metabolic control can be considered as the cornerstone in diabetes management and its complications. Acquiring HbA1c target minimizes the risk for developing microvascular complications and may also protect CVD, particularly in newly diagnosed patients.81 Carbohydrate intake has a direct effect on postprandial glucose levels in people with diabetes and is the principal macronutrient of worry in glycemic management.82 In addition, an individual’s food choices and energy balance have an effect on body weight, blood pressure, and lipid levels directly. Through the mutual efforts, health-care professionals can help their patients in achieving health goals by individualizing their nutrition interventions and continuing the support for changes.83-85 A study suggested that intake of virgin olive oil diet in the Mediterranean area has a beneficial effect on the reduction of progression of T2DM retinopathy.86 Dietary habits are essential elements of individual cardiovascular and metabolic risk.87 Numerous health benefits have been observed to the Mediterranean diet over the last decades, which contains abundant intake of fruit and vegetables. The beneficial effects of using fish and olive oil have been reported to be associated with improved glucose metabolism and decreased risk of T2DM, obesity and CVD.88
The process of type 2 diabetes begins years or even decades before the diagnosis of diabetes, with insulin resistance. Insulin resistance is the beginning of the body not dealing well with sugar, which is the breakdown product of all carbohydrates. Insulin tells certain body cells to open up and store glucose as fat. When the cells stop responding your blood sugar rises, which triggers the release of more insulin in a vicious cycle. Insulin resistance is associated with abdominal obesity, high blood pressure, high triglycerides, and low HDL ("good cholesterol"). When these occur together, it is known as metabolic syndrome or pre-diabetes. It is a risk factor for heart disease and type 2 diabetes.
Often, people with type 2 diabetes start using insulin with one long-acting shot at night, such as insulin glargine (Lantus) or insulin detemir (Levemir). Discuss the pros and cons of different drugs with your doctor. Together you can decide which medication is best for you after considering many factors, including costs and other aspects of your health.
At the close of the DPP trial, investigators offered lifestyle intervention to all 3 groups. Patients in the original metformin group continued to take metformin (with participants unblinded to assignment); patients in the original lifestyle intervention group were offered additional lifestyle support.5 At a median follow-up of 10 years after initial enrollment in the DPP trial, metformin reduced the incidence of overt diabetes by 18% compared with placebo (95% CI, 7%-28%), and lifestyle intervention reduced it by 34% (95% CI, 24%-42%; no statistic of comparison supplied).
Meanwhile, processed or packaged foods should be avoided or limited in your diabetes diet because, in addition to added sugars and processed carbohydrates, these foods are often high in sodium and therefore may increase your blood pressure and, in turn, the risk of heart disease or stroke — two common complications of diabetes. It’s important to keep your blood pressure in check when managing diabetes.
Recently, evidence suggested a link between the intake of soft drinks with obesity and diabetes, resulting from large amounts of high fructose corn syrup used in the manufacturing of soft drinks, which raises blood glucose levels and BMI to the dangerous levels.38 It was also stated by Assy39 that diet soft drinks contain glycated chemicals that markedly augment insulin resistance. Food intake has been strongly linked with obesity, not only related to the volume of food but also in terms of the composition and quality of diet.40 High intake of red meat, sweets and fried foods, contribute to the increased the risk of insulin resistance and T2DM.41 In contrast, an inverse correlation was observed between intake of vegetables and T2DM. Consumption of fruits and vegetables may protect the development of T2DM, as they are rich in nutrients, fiber and antioxidants which are considered as protective barrier against the diseases.42 Recently, in Japanese women, a report revealed that elevated intake of white rice was associated with an increased risk of T2DM.43 This demands an urgent need for changing lifestyle among general population and further increase the awareness of healthy diet patterns in all groups.
