Diabetes is a chronic medical condition that affects millions of people worldwide. Unmanaged diabetes may lead to blindness, kidney failure, heart disease, and other serious conditions. However, it is possible to prevent diabetes by adopting a well-balanced diet, staying active, and controlling your weight. Research suggests that a diet rich in whole grains and the inclusion of coffee or tea can help lower the risk of developing type 2 diabetes. Additionally, regular exercise can increase insulin sensitivity and help prevent diabetes. It is important to note that prediabetes, characterized by elevated fasting blood sugar levels, can be controlled and even reversed through diet and lifestyle changes, thus preventing the progression to diabetes.

What You'll Learn
Eat a balanced diet
Eating a balanced diet is key to preventing diabetes. According to Tara Seymour, an advanced practice clinical dietitian and diabetes educator at Johns Hopkins, a balanced approach to diet is essential to ward off the progression of prediabetes. This means that all foods can be included in the meal plan, and it is important to avoid fad diets that promise quick fixes. Instead, gradual behaviour changes should be made to improve your overall diet.
A well-balanced diet includes a variety of nutrient-dense foods that are rich in protein, healthy fats, vitamins, minerals, antioxidants, and fibre. For example, healthy fats like monounsaturated and polyunsaturated fats can be found in olive oil, nuts, avocados, and some types of fish. These foods not only provide essential nutrients but also help to lower cholesterol and protect heart health.
In addition to including a variety of healthy fats, it is important to focus on adding more fruits and vegetables to your diet. Fruits and vegetables are packed with vitamins, minerals, and fibre, and they can help satisfy your sweet tooth without the added sugar found in processed foods. When it comes to carbohydrates, opt for healthy options such as whole grains like brown rice, farro, or quinoa. These complex carbohydrates provide sustained energy and can help manage blood glucose levels.
The Mediterranean diet is often recommended as a gold standard for people with prediabetes. This diet emphasizes whole grains, lean protein, and healthy fats, which can help manage blood glucose levels and promote overall health. Additionally, portion control is important, and the Diabetes Plate can be a useful tool to help you portion your plate and manage your diabetes. This approach is easy to customize and can be adapted to your food preferences.
Finally, staying hydrated is an important part of a balanced diet. Water should be your primary beverage of choice, as it helps to limit sugar intake and improve blood sugar management. Research also suggests that including coffee or tea in your diet may have protective effects against diabetes due to their antioxidant compounds. However, it is important to avoid adding sugars and syrups to these beverages, as they can increase blood sugar levels.

Exercise regularly
Regular exercise is a cornerstone of diabetes prevention and treatment. It is a powerful tool that can help prevent and manage diabetes, especially in those with prediabetes. Exercise has been shown to decrease the chances of developing diabetes by up to 58% in high-risk individuals.
Exercise helps in diabetes prevention by improving insulin sensitivity, allowing cells to effectively absorb glucose from the bloodstream and reducing insulin resistance. This, in turn, helps regulate blood sugar levels. Regular exercise also aids in weight management by burning calories and building muscle mass. Excess weight is a significant risk factor for diabetes, and even modest weight loss can significantly impact preventing the disease.
The American Diabetes Association (ADA) recommends that adults participate in at least 150 minutes of moderate-to-vigorous aerobic activity per week, spread over at least three days. This can include activities such as walking, cycling, swimming, or household chores. Additionally, two to three sessions of resistance exercises per week on non-consecutive days are advised.
It is important to note that you don't have to spend hours at the gym to reap the benefits of exercise. Small changes, such as taking the stairs instead of the elevator or walking instead of driving short distances, can contribute to your overall physical activity levels. You can start slowly and gradually increase your activity levels. It is always good to consult a doctor before starting any new exercise routine, especially if you have prediabetes or diabetes.

Control your weight
Weight control is a crucial aspect of preventing diabetes, especially when coupled with a healthy diet and active lifestyle. Losing weight can be challenging, but even losing a few pounds can make a significant difference in your health and energy levels, and it can also make it easier to manage diabetes if you already have it.
The key to successful weight loss is finding the right balance of exercise, healthy eating, and portion control. It is important to avoid fad diets and instead focus on gradual behaviour changes that will lead to a well-balanced diet. A balanced diet does not mean eliminating entire food groups or following restrictive diets; instead, it involves including a variety of foods in appropriate portions. Emotional eating can be a common challenge when trying to lose weight, so it is helpful to identify any emotional triggers that may cause you to reach for food.
Regular exercise is an important component of weight loss and diabetes prevention. Aim for at least 150 minutes per week of moderate to vigorous exercise or 10,000 steps daily, but be sure to consult your doctor before starting any new exercise routine. Exercise can increase insulin sensitivity, which helps prevent diabetes, and it also boosts heart health.
In addition to exercise, it is important to stay hydrated by drinking plenty of water. Water should be your primary beverage, but research also suggests that including coffee or tea in your diet may help reduce the risk of diabetes due to their antioxidant compounds. However, be mindful of adding sugars or syrups to your drinks, as these can increase blood sugar levels and negate the potential benefits.

Avoid sugary drinks
Drinking water, coffee, tea, and artificially sweetened drinks are all healthier alternatives to sugary drinks. Sugary drinks are loaded with calories and provide virtually no other nutrients. Research indicates that people who consume sugary drinks do not feel as full as they would have if they had consumed the same calories from solid food. They also do not compensate for the high caloric content by eating less food. The average can of sugar-sweetened soda or fruit punch provides about 150 calories, almost all of them from added sugar. If you were to drink just one of these sugary drinks every day without cutting back on calories elsewhere, you could gain up to 5 pounds in a year.
In addition to weight gain, regularly consuming these sugar-loaded beverages can increase the risk of type 2 diabetes, heart disease, and other chronic diseases. Higher consumption of sugary beverages has also been linked with an increased risk of premature death. One large observational study in 2,800 people found that those who drank more than 2 servings of sugary beverages per day had a 99% and 20% increased risk of LADA and type 2 diabetes, respectively. Another study that followed 40,000 men for two decades found that those who averaged one can of a sugary beverage per day had a 20% higher risk of having a heart attack or dying from one compared to men who rarely consumed sugary drinks.
To reduce the risk of diabetes, it is recommended to replace one daily serving of a sugary beverage with water, coffee, or tea. While water should be your primary beverage, research suggests that including coffee or tea in your diet may help you avoid diabetes. Studies report that daily coffee intake reduces the risk of type 2 diabetes by up to 54%, with the greatest effect generally seen in people with the highest consumption. Green tea, in particular, has been found to have a positive effect on general health and may lower the risk of type 2 diabetes. However, it is important to avoid adding sugar, milk, cream, or flavored syrups to your coffee or tea, as this increases the overall calorie count and may affect your blood sugar levels.

Eat whole grains
Eating whole grains is a key component of a diabetes-preventing diet. Whole grains are an excellent source of dietary fibre, which plays a crucial role in regulating blood sugar levels and promoting insulin sensitivity. Additionally, whole grains are digested more slowly than refined grains, helping to keep blood sugar levels stable and preventing spikes in insulin.
When it comes to choosing whole grains, there are a variety of options to select from. Some examples include oatmeal, brown rice, quinoa, barley, and whole wheat bread. These grains are packed with nutrients and offer an array of health benefits, including a reduced risk of type 2 diabetes. They are also a good source of essential vitamins and minerals, such as magnesium, which is important for blood sugar control.
It is beneficial to incorporate a variety of whole grains into your diet to maximise their effects. Aim for a minimum of two to three servings per day. A serving size typically equates to a half cup of cooked grains or one slice of whole-grain bread. However, it is important to be mindful of portion sizes, as even healthy whole grains can contribute to weight gain if overconsumed.
The versatility of whole grains allows for numerous delicious and nutritious preparation methods. Start your day with a nourishing bowl of oatmeal topped with fresh fruit and nuts for breakfast. For lunch or dinner, try swapping out refined grains for their whole-grain counterparts, such as opting for brown rice or quinoa instead of white rice. You can also experiment with different types of whole-grain bread for sandwiches or as a side dish.
In addition to their positive impact on blood sugar regulation, whole grains have been linked to a reduced risk of other chronic diseases. Research has indicated that regularly including whole grains in your diet can lower the chances of developing heart disease and certain types of cancer, and may even aid in weight management. Thus, incorporating whole grains into your diet not only contributes to diabetes prevention but also promotes overall health and well-being.
