Type 2 diabetes is among the most prevalent chronic diseases in the Kingdom of Saudi Arabia, where lifestyle factors including diet significantly influence the risk of developing it. However, the good news is that adopting simple daily dietary habits can make a big difference in preventing this disease.

In this article, we review a set of dietary practices proven effective in reducing the risk of type 2 diabetes, based on recommendations from nutrition and public health experts. These tips are practical and easy to apply in daily life, and do not require drastic changes.

Eat plenty of dietary fiber

Dietary fiber is one of the most important elements in regulating blood sugar levels. It slows down the absorption of carbohydrates, preventing sudden spikes in glucose after meals. Rich sources of fiber include leafy vegetables like spinach and arugula, fresh fruits like apples and oranges, legumes like lentils and chickpeas, and whole grains like oats and quinoa.

Consuming fiber also improves insulin sensitivity, a key factor in diabetes prevention. To reap its benefits, it is recommended to include a source of fiber in every meal, such as adding a vegetable salad to lunch or eating a handful of nuts as a snack.

Choose complex carbohydrates over simple ones

Carbohydrates directly affect blood sugar, so choosing the right type is vital. Complex carbohydrates, such as those found in whole grains, whole wheat bread, brown rice, and oats, digest slowly and provide sustained energy, while simple carbohydrates like white sugar and white flour rapidly raise blood sugar levels.

It is advised to replace white bread with whole wheat bread, white rice with brown rice or bulgur. Additionally, sweet potatoes can be used instead of white potatoes. These alternatives not only protect against diabetes but also provide a longer feeling of fullness.

Moderate fat intake and choose healthy fats

Not all fats are harmful; healthy fats play an important role in improving insulin sensitivity and reducing inflammation associated with insulin resistance. Healthy fats include olive oil, avocado, nuts, and fatty fish such as salmon and tuna.

Trans and saturated fats found in fried foods, fast food, and processed baked goods should be avoided. Olive oil can be used in cooking and salads, and avocado slices can be added to sandwiches instead of mayonnaise.

Regulate meal times and reduce added sugars

Meal timing plays a role in regulating blood sugar. It is recommended to eat three main meals and two snacks at regular intervals to avoid blood sugar lows or spikes. Reducing added sugars is also essential, as sodas, sweetened juices, and desserts cause harmful blood sugar spikes.

Sugary drinks can be replaced with water or unsweetened tea, and fresh fruits can be eaten instead of processed sweets. Also, reading food labels to identify hidden sugars helps control their intake.

Drink water regularly and monitor portion sizes

Drinking adequate amounts of water improves body functions and helps the kidneys eliminate excess sugar. It is recommended to drink at least 8 cups daily, increasing the amount in hot weather—which applies to most days of the year in Saudi Arabia.

Monitoring portion sizes also prevents excessive calorie intake, helping to maintain a healthy weight, which is an important factor in diabetes prevention. Smaller plates and measuring portions by eye or by cup can ensure balance.

Adopting these daily dietary habits not only protects against type 2 diabetes but also improves overall health and provides the body with energy and vitality. Remember that small and consistent changes are the most impactful in the long run. Start applying one of them today, add another gradually, and you will notice the difference in how you feel and your health.
