Reviewed by: | Author: Manoja Kalakanti

Diet is one of the most critical components of controlling the condition. Some foods can cause fluctuations in blood sugar levels while others keep it steady. Thus, what you eat can make or break your effort in keeping diabetes under control.

How to control diabetes with diet

Many other factors result in these fluctuations, such as genetics, physical activity, weight, stress, and sleep. But, the role of diet in maintaining sugar levels is vital. This article will talk about 9 ways to manage sugar levels and control diabetes through diet. Let’s first understand the relationship between food and diabetes management.

Relation Between Food and Managing Sugar Levels to Control Diabetes

Your body converts the food you eat into sugar (glucose). This sugar that circulates in the blood is used for energy and is called blood sugar. Too much sugar in your body has a detrimental effect on your health and causes diabetes – a condition characterized by excess sugar in the bloodstream.

Your body breaks down food differently; it separately breaks down the protein, fats, carbohydrates and vitamins. Carbohydrates have the highest impact on your blood sugar levels. Carbohydrates are broken down and turn into blood sugar. The more carbs you eat, the more sugar will be released into your bloodstream. Carbs in liquid form are absorbed even quicker; thus, it instantly spikes your sugar levels.

So what is a healthy blood sugar range? A blood sugar level less than 140 mg/dL (7.8 mmol/L) is normal.

How is food and diabetes connected

But fibre is one such part of carbohydrate that is not turned into sugar; hence it helps control the blood sugar levels. Therefore, the food you eat directly impacts the sugar levels, either increasing it quickly or causing a slow, gradual increase.

9 Diet Principles to Maintain Sugar Levels

Your diet has a massive influence on the management of diabetes. The ability of food to lower blood sugar or spike it is well researched. Often, a significant impediment in the successful management of diabetes is a lack of a disciplined diet.

How to control sugar levels through diet

While the importance of diet in maintaining healthy sugar levels is well known, it is equally important to engage in physical activity, control stress, and get adequate sleep. Below are some of the critical diet principles to follow for effectively controlling diabetes:

1. Include complex carbohydrates

For a long time, carbs had gained a bad reputation due to fitness experts. This misconception has been put to rest, as people have realised the incredible health benefits of carbohydrates. But, eating the right type of carb in the right amount can be healthy and help maintain sugar levels. Your body breaks down carbs into sugars, which is then used by the body for energy.

And since they are so quickly broken down into glucose for energy, carbs have a significant impact on your blood sugar levels compared to fats and protein. So, you must ensure that your carb intake is under control, but there is no need to avoid it. Avoid unhealthy refined carbs such as white rice, white bread, candy, soda and other processed foods.

These unhealthy carbs cause a spike in sugar levels. Instead, eat healthy, complex carbs such as whole fruits and vegetables, lentils and whole grains. The healthy carbs contain fibre, which is absorbed slowly, and does not cause any spike in blood sugar levels.

2. Low glycemic foods need to be consumed

The glycemic index shows the absorption and digestion of foods and the resultant rise in blood sugar levels. Foods high in glycemic index cause a spike in sugar levels, while low glycemic index foods cause blood sugar levels to drop. Eating low to moderate glycemic index foods such as oats, beans, lentils, legumes and non-starchy vegetables help in reducing the glycemic index. It is not the type of carbs that determines the impact on sugar levels but the amount you consume.

3. Include more fibre-rich foods

Fibre slows down the digestion and absorption of carbs and sugar. This helps control the swing in blood sugar levels. It has a satiating effect and is also good for digestive health. There are two kinds of fibre – soluble and insoluble. While they are both beneficial for health, soluble fibre is known to affect the management of diabetes positively. Incorporate fibre rich foods such as whole fruits, vegetables, and whole grains into your diet to control diabetes.

4. Include PUFA, MUFA (Polyunsaturated fatty acids, Monounsaturated fatty acids)

Include PUFA and MUFA oils instead of saturated fats. MUFA is known to improve cholesterol and keeps blood sugar levels under control. Omega-3 is rich in PUFA, and helps in managing depression and anxiety. MUFA-rich foods include olive oil, almonds, cashews, avocados and peanut oil. PUFA sources include flaxseeds, walnuts, peanuts and sunflower seeds.

5. Low dairy consumption

If you are wondering how to regulate blood sugar, you might want to cut down on dairy consumption. Dairy products such as milk, cheese, and yoghurt may not cause an immediate spike in blood sugar levels, but consistent consumption may lead to insulin resistance. More study is required to determine the effects of dairy on people with diabetes.

6. Immunity boosting foods intake

People with diabetes need to improve their immune strength, especially with COVID-19 around. Diabetes can weaken your immune system, thus making you vulnerable to illnesses. Foods such as nuts, broccoli, carrots, garlic and citrus fruits are diabetes-friendly foods that can boost your immune system.

7. Avoid trans fats

Fats are a healthy macronutrient that we must include in our daily diet. But not all fats are equals; some are healthy while others can result in severe health problems. People with diabetes must be more careful when choosing a fat. Trans fats are found in processed foods and baked goods such as chips and cakes, which may also contain hydrogenated oil. It has a negative impact on cholesterol levels and heart health. This can make controlling diabetes difficult. Always check the label of foods; go for products free of trans fats or hydrogenated oil.

8. Eat less meat and processed meat

Red meat and processed meat are bad for heart health and cholesterol levels. Experts do not suggest avoiding meat; instead, they recommend limiting the amount. You can also go for lean protein.

9. Limiting foods that are high in sugar content

Sugar is added to several packaged foods and drinks, making it difficult to keep track of the amount consumed. Sugar directly affects blood sugar levels and also leads to obesity and other health conditions. While you do not need to avoid sugar altogether if you have diabetes, limiting its consumption is better.

Try these principles if you are asking yourself how to bring down blood sugar. Apart from these principles, a comprehensive diet plan shown below can also help you manage the condition.
