Nutrition and Management of Type 2 Diabetes: Recommendations and More

Last update: 05 February, 2021

Type 2 diabetes has become a contemporary endemic disease. Besides not having a cure, it comes with associated complications of various types. It’s a serious health problem that, in most cases, is derived from a poor diet. How can patients improve their nutrition to properly manage type 2 diabetes?

Nutrition and diabetes recommendations

As concluded by a publication in Diabetes, Metabolic Syndrome and Obesity, education about nutrition and diabetes is crucial to properly manage the disease.

Therefore, it’s important that nutritionists and physicians inform patients about topics such as carbohydrate portions, blood glucose control, and the importance of physical exercise.

On the other hand, there are other nutritional recommendations that can be taken into account to address this health problem in regard to the patient’s diet. In any case, it’s important that each patient asks a professional to determine an individual dietary treatment.

Intermittent fasting

Intermittent Fasting.
Intermittent fasting has been shown to be beneficial in controlling type 2 diabetes. However, we recommend doing it under the supervision of a nutritionist.

One of the main problems resulting from diabetes is the control of the glucose curve. Intermittent fasting, especially 16:8, improves this situation and reduces insulin resistance, according to a review published in Translational Research. Thus, skipping breakfast can be a beneficial strategy in managing diabetes.

Some studies show that a 24-hour fast may also be beneficial. The problem in these cases is that it tends to be less operative due to adhesion problems. Not everyone is able to go that long without eating, especially if they’re subject to some type of physical work.

We must also consider that diabetes is usually associated with excess weight. In these situations, intermittent fasting also becomes a good ally.

Eliminating a daily meal reduces the number of calories in the diet and therefore facilitates weight loss. In this way, a great number of complications associated with overweight and obesity are prevented.

Whole foods, keys to nutrition to control type 2 diabetes

Sugar and refined flours are two of the great problems of modern food. They trigger insulin peaks, and favor the onset and lack of control of type 2 diabetes. Opting to reduce eating processed foods as much as possible, and substituting refined flours and cereals for their integral versions are great decisions.

Whole grain foods have a slower rate of intestinal absorption. Thus, sugar passes into the blood progressively and there’s less aggression towards the pancreas. Switching wheat for other cereals of higher quality, such as spelt or quinoa, are interesting strategies when we talk about the prevention and control of diabetes.

Reducing the amount of processed foods in the diet is one of the great milestones of modern nutrition. Since our mouths are so used to large amounts of sugar, it’s often difficult to reduce the amount of sweetness in the diet. Despite this, opting for fresh foods is a great investment in health.

Don’t consume fizzy drinks or alcohol

Some beer.
Drinking soft drinks and alcoholic beverages affects the health of patients with type 2 diabetes. In addition, it can lead to a state of dehydration.

Both sweetened soft drinks and their zero sugar versions put great stress on the pancreas. The same goes for alcohol and its hypoglycemic capacity. In addition, they promote weight gain and obesity. Thus, removing them from the diet usually produces a decrease in body mass and a notable improvement in the state of health.

On the other hand, alcohol can contribute to a state of dehydration. As we’ll see in just a bit, hydration is fundamental in people with diabetes. Therefore, diabetics should completely avoid alcohol.

Exercise

Exercise is a great ally in the fight against type 2 diabetes. Specifically, as observed in a study published in Current Diabetes Reviews, high-intensity intervallic exercise helps reduce insulin resistance and control body weight. This way, doing exercise regularly becomes a necessary habit in both the prevention and management of this disease.

Combining moderate-intensity exercise with intermittent fasting improves exercise results in terms of glucose control. It reduces insulin resistance and helps fat and body weight loss. As a result, the person’s health is significantly improved.

Staying hydrated

Dehydration is a common problem among people with diabetes. High blood glucose causes increased kidney excretion and thus fluid loss.

It’s important for people with diabetes to always stay well hydrated to avoid major complications. Drinking frequently and not waiting to be thirsty are two basic points in these situations.

Improve your nutrition to control diabetes

It’s important to improve nutrition to help control type 2 diabetes. In this sense, the patient should eat whole foods, stay hydrated, and avoid bad habits, such as alcohol and tobacco consumption. In addition, patients can also explore other options like intermittent fasting, but always make sure the diabetic is under the careful eye of a nutritionist while fasting.
