The Caerphilly Heart Disease Study followed 2,375 male subjects over 20 years and suggested the daily intake of a pint (~568 ml) of milk or equivalent dairy products more than halved the risk of metabolic syndrome. Some subsequent studies support the authors' findings, while others dispute them. A systematic review of four randomized controlled trials found that a paleolithic nutritional pattern improved three of five measurable components of the metabolic syndrome in participants with at least one of the components.

The progression of nephropathy in patients can be significantly slowed by controlling high blood pressure, and by aggressively treating high blood sugar levels. Angiotensin converting enzyme inhibitors (ACE inhibitors) or angiotensin receptor blockers (ARBs) used in treating high blood pressure may also benefit kidney disease in patients with diabetes.
Treatment of hypertension is important, despite the fact that it rarely causes noticeable symptoms at the early stages. Hypertension accelerates atherosclerosis, which leads to coronary artery disease, heart attacks, heart failure, strokes, kidney failure, peripheral artery disease, and aortic aneurysms. Treating hypertension in the early stages has been shown to prevent these complications.
The fact that the diagnostic criteria for metabolic syndrome vary between ethnic populations is testimony to significant nuances in the manifestation of metabolic syndrome in these groups. The original metabolic syndrome criteria were derived in mostly Caucasian populations, and some have argued for modification of individual criteria for specific ethnic subgroups, as has been done with waist circumference for patients of Asian origin. 
Type 2 diabetes was also previously referred to as non-insulin dependent diabetes mellitus (NIDDM), or adult-onset diabetes mellitus (AODM). In type 2 diabetes, patients can still produce insulin, but do so relatively inadequately for their body's needs, particularly in the face of insulin resistance as discussed above. In many cases this actually means the pancreas produces larger than normal quantities of insulin. A major feature of type 2 diabetes is a lack of sensitivity to insulin by the cells of the body (particularly fat and muscle cells).
When it comes to laboratory values, numbers like blood glucose and A1C levels are commonly checked. Less often, doctors order a test for your fasting insulin level; yet this test can help predict your risk of developing prediabetes and metabolic syndrome. Insulin plays a key role in metabolism, and high insulin levels can promote obesity, stimulate hunger, and increase the storage of fat.
The oral glucose tolerance test (OGTT), or glucose tolerance test is a blood test used (not routinely however) to diagnose diabetes, and gestational diabetes. Information in regard to reliability of the oral glucose tolerance test is important, as some conditions (common cold), or food (caffeine), or lifestyle habits (smoking) may alter the results of the oral glucose tolerance test.
In particular, eat a healthy diet that includes fruits, vegetables, and whole grains. Exercise is also important when it comes to preventing this condition. Regular physical activity will reduce your blood pressure, blood sugar, and cholesterol levels. The key is to try to maintain a healthy weight. Talk to your doctor before beginning an exercise program or radically changing your diet.
Exposure to certain viral infections (mumps and Coxsackie viruses) or other environmental toxins may serve to trigger abnormal antibody responses that cause damage to the pancreas cells where insulin is made. Some of the antibodies seen in type 1 diabetes include anti-islet cell antibodies, anti-insulin antibodies and anti-glutamic decarboxylase antibodies. These antibodies can be detected in the majority of patients, and may help determine which individuals are at risk for developing type 1 diabetes.
