What is diabetes and how does diet influence it?

Diabetes is a chronic disease that affects how the body turns food into energy. Normally, your body breaks down the food you eat into sugar (glucose) and releases it into your bloodstream. When your blood sugar level goes up, your pancreas releases a hormone called insulin. Insulin acts like a key that lets blood sugar into your body’s cells for use as energy.

In people with diabetes, the body either doesn’t make enough insulin or can’t use it effectively. This causes blood sugar to stay in the bloodstream instead of entering the cells. Over time, having too much sugar in your blood can cause serious health problems, such as heart disease, vision loss, and kidney disease.

There are several types of diabetes, but the most common are type 1 and type 2.

• Type 1 Diabetes: The body doesn’t produce any insulin. This is often diagnosed in children and young adults. People with type 1 diabetes need to inject insulin daily to survive.
• Type 2 Diabetes: The body doesn’t produce enough insulin or doesn’t use it well. It’s the most common type of diabetes and develops most often in adults. Obesity, physical inactivity, and a family history are major risk factors for type 2 diabetes.

The Influence of Diet on Diabetes

Diet plays a fundamental role in both managing and preventing diabetes. What you eat directly influences your blood sugar levels.

For people with diabetes, diet is key to controlling blood sugar levels. A balanced diet helps keep blood sugar within a target range, which reduces the risk of long-term complications. The basic principles of a diabetic diet include:

• Controlling carbohydrate intake: Carbohydrates are the primary macronutrient that turns into glucose. It’s important to choose complex carbohydrates (whole grains, fruits, vegetables) instead of simple ones (sugars, sweets, sugary drinks), as the former release glucose into the blood more slowly.
• Consuming fiber: Fiber helps control blood sugar levels by slowing down the digestion and absorption of carbohydrates. It is found in fruits, vegetables, legumes, and whole grains.
• Limiting saturated fats: These fats can increase the risk of heart disease, a common complication of diabetes. It’s better to opt for healthy fats, such as those found in avocado, nuts, and olive oil.
• Controlling portion sizes: Eating too much, even of healthy foods, can raise blood sugar levels.
• Reducing added sugars: Sugary drinks, sweets, and desserts are concentrated sources of sugar that can cause rapid spikes in blood glucose.

For preventing diabetes, diet is also a crucial factor. An unhealthy diet—high in calories, saturated fats, and sugars—along with a sedentary lifestyle can lead to weight gain and insulin resistance, which is a precursor to type 2 diabetes. Maintaining a healthy weight and following a balanced diet are the best strategies to prevent the onset of type 2 diabetes.

In summary, diabetes is a metabolic disorder where the body has trouble using glucose for energy. Diet is a fundamental pillar in both the treatment and prevention of the disease, as what we eat directly impacts blood sugar levels and body weight, two key factors in the development and management of this condition.

The Role of Carbohydrates

Carbohydrates are one of the three main macronutrients (along with proteins and fats) and are the body’s primary source of energy. When you consume carbohydrates, your digestive system breaks them down into glucose, which is then absorbed into the bloodstream. This glucose is used by cells for energy.

There are two main categories of carbohydrates:

1. Simple Carbohydrates: Also known as sugars. They are found in foods like candy, soda, pastries, and fruits. They are digested and absorbed quickly, causing a rapid rise in blood sugar levels.
2. Complex Carbohydrates: Found in foods like whole grains, legumes, and starchy vegetables. These carbs are made of chains of sugar molecules that take the body longer to break down. As a result, glucose is released into the bloodstream more slowly and gradually.

For people with diabetes, the choice of carbohydrates is crucial. Consuming too many simple carbs can cause dangerous blood sugar spikes, while complex carbs help keep levels more stable.

What is the Glycemic Index (GI)?

The glycemic index (GI) is a tool that ranks carbohydrate-containing foods based on how quickly they raise blood sugar levels after eating. The scale runs from 0 to 100, with pure glucose serving as the reference, assigned a GI of 100.

• Foods with a High GI (70 or more): They are broken down quickly and cause a rapid and sharp rise in blood glucose. Examples include white bread, potatoes, white rice, and sugary cereals.
• Foods with a Medium GI (56-69): Cause a moderate rise in blood glucose. Examples include basmati rice, whole wheat bread, and orange juice.
• Foods with a Low GI (55 or less): They are broken down slowly and lead to a gradual, slower rise in glucose. Examples include oats, most fruits, legumes, non-starchy vegetables, and pasta.

Why is the Glycemic Index Important?

Knowing the GI is a useful tool for those looking to control their blood sugar levels, whether to manage diabetes or prevent it.

• Blood Sugar Control: Choosing low-GI foods can help prevent sharp spikes and drops in glucose, making it easier to manage the disease.
• Weight Management: Low-GI foods are often rich in fiber and make you feel full longer, which can help control appetite and maintain a healthy weight.
• Overall Health: A diet based on low-GI foods often aligns with a healthier diet in general, as it prioritizes whole grains, fruits, vegetables, and legumes over processed foods.

Additional Considerations: Glycemic Load (GL)

While the GI is a valuable tool, it has its limitations. The GI does not account for the amount of carbohydrates you consume. This is where the Glycemic Load (GL) comes in.

The GL combines the quality of the carbohydrate (its GI) with the quantity consumed. It’s calculated by multiplying a food’s GI by the amount of carbohydrates in a serving and then dividing the result by 100.

• Low GL (10 or less): The food is considered to have little impact on blood sugar.
• Medium GL (11-19): Moderate impact.
• High GL (20 or more): Major impact.

For example, watermelon has a high GI, but a typical serving has a relatively low amount of carbohydrates, so its GL is low. This means that eating a moderate serving of watermelon won’t raise your blood sugar as much as eating a large serving of white rice, which has both a high GI and a high GL.

In conclusion, carbohydrates are an essential part of the diet, but choosing the right type and quantity is fundamental. By using tools like the glycemic index and, even better, the glycemic load, you can make informed decisions that help you maintain optimal blood sugar control and improve your overall health.

Foods with High Added Sugars

Foods and drinks with added sugars are the ones that raise blood glucose levels the fastest. They not only lack nutrients but also contribute to weight gain.

• Sugary drinks: Sodas, processed fruit juices, sweet tea, and sports drinks. Liquid sugar is absorbed very quickly, causing an almost instant glucose spike.
• Sweets and desserts: Cakes, cookies, ice cream, candies, and milk chocolates. These products are loaded with sugars and unhealthy fats.
• High-fructose corn syrup and other sweeteners: These are found in many processed foods and should be avoided.

Refined Carbohydrates

These carbohydrates, unlike their whole-grain counterparts, have been processed to remove fiber and other important nutrients. They are digested quickly, causing a sharp rise in glucose.

• White bread, white rice, and white pasta: These are simple carbohydrates that are digested quickly.
• Sugary breakfast cereals: Many processed cereals are made with refined grains and contain large amounts of sugar.
• Processed snacks: Potato chips, crackers, and other similar snacks often contain refined carbohydrates, unhealthy fats, and excessive sodium.

Saturated Fats

People with diabetes have a higher risk of cardiovascular disease. Therefore, it is crucial to limit fats that can harm the heart.

• Saturated fats: Found in red meat (fatty cuts), butter, cheese, and whole milk. Excessive consumption can increase “bad” LDL cholesterol.
• Trans fats: These are artificial fats found in many processed and fried foods, such as fast food, commercial pastries, and margarine. These fats are particularly harmful to the heart.

High-Sodium Foods

Limiting salt intake is important for everyone, but especially for people with diabetes, as they have a higher risk of high blood pressure.

• Processed foods: Canned soups, deli meats, ready-made sauces, and frozen meals often have a high sodium content.
• Restaurant food: Food from restaurants, especially fast food, is usually very high in sodium.

What Can You Do Instead of Consuming These Foods?

Instead of focusing on what you should avoid, think about healthier options:

• Substitute sugary drinks with water, lemon water, or unsweetened tea.
• Choose complex carbohydrates like whole-grain bread and pasta, brown rice, oats, and legumes.
• Opt for lean protein sources like fish, skinless chicken, and tofu, and use healthy fats like olive oil.
• Prepare your own meals at home to control the amount of sodium and fat.

By limiting these foods and opting for healthier alternatives, you can improve your diabetes management and reduce the risk of complications, leading to a better quality of life.
