Beyond Carbs: The Surprising Roles of Protein and Fats in Managing Type 1 Diabetes

Type 1 diabetes is an autoimmune condition where the body produces little to no insulin due to the destruction of pancreatic beta cells.

It can develop at any age but is most common in children, adolescents, and young adults.

In Malaysia, misdiagnosis is common, especially in children under 5, often leading to delayed treatment.

WHY GOOD TYPE 1 DIABETES MANAGEMENT IS IMPORTANT

Ignoring blood sugar levels is like ignoring a car’s warning light. Eventually, something will break down!

Short-Term Risks

Diabetic ketoacidosis (DKA)

• A complication that results from increased levels of a chemical called ketones in the blood.
• It causes excessive thirst, frequent urination, fatigue, and vomiting.
• Symptoms include fruity-smelling breath, nausea, and muscle stiffness.
• This is a medical emergency and requires immediate medical attention.

Long-Term Risks

• Kidney failure (nephropathy)
• Nerve damage (neuropathy)
• Vision loss (retinopathy)
• Foot infections

To manage type 1 diabetes well and to reduce the risk of complications, a personalized plan involving doctors, dietitians, and pharmacists is key. This plan includes medications, balanced nutrition, and exercise to ensure a healthy lifestyle.

THE ROLES OF PROTEIN AND FATS IN BLOOD SUGAR MANAGEMENT 

How Protein Affects Blood Sugar

• Do you know protein can raise blood sugar levels—but slowly?
• This is due to the action of glucagon, which is a hormone that helps the liver produce glucose from amino acids.
• High protein intake or fasting can cause a delayed glucose rise, typically 3 to 5 hours after eating.
• On the other hand, protein also aids in weight loss by promoting a feeling of fullness, reducing overeating.

How Fats Influence Blood Sugar

• Fat doesn’t directly convert into glucose but slows digestion, delaying blood sugar spikes.
• However, excessive fat intake, especially saturated and trans fats, can increase insulin resistance.

WITH THIS INFORMATION IN MIND, HERE’S HOW WE CAN PLAN BALANCED MEALS FOR BETTER CONTROL OF TYPE 1 DIABETES

Combining carbohydrates, fibre, protein, and fats in meals can result in:

• Smaller glucose spikes
• Longer-lasting satiety

For meals high in protein and fats, insulin adjustments may be needed to maintain stable blood sugar levels.

What Are the Ideal Amounts of Protein and Fats?

There is no universally ideal amount of protein and fat recommended for optimizing glycaemic control, so dietary goals should be personalized based on individual caloric needs.

Generally:

• Adults: Protein (15–20% of total daily calories), fats (20–35%), carbs (45–60%)
• Children and teens: Protein (15–20%), fats (30–35%), carbs (45–55%)

You should consult a dietitian to calculate how many calories you should eat and are currently eating daily, and from that point, you can also figure out the amount and types of proteins, fats, and carbs you should eat in each meal.

A Guide to Healthy Food Options

Protein options:

• Plant-based options include beans, lentils, tofu; comes with added benefits of fibre and healthy fats.
• Poultry and eggs.
• Fish, especially omega-3-rich options like salmon, and shellfish.
• Limit consumption of red meats.

Fat options:

• Choose monounsaturated fats such as olive oil, canola oil, nuts such as pumpkin seeds.
• Choose polyunsaturated fats such as sunflower oil, corn oil.
• Avoid or limit saturated fats (butter, cheese, etc) and trans fats (fast foods, deep-fried foods, processed foods).

KEY TAKEAWAYS

• Meals with a healthy balance of carbs, proteins, and fats help maintain steady blood sugar and prevent overeating.
• Protein can cause a slow glucose rise; opt for lean sources.
• Fats delay glucose absorption; prioritize unsaturated fats.

Are you ready to take control of your blood sugar with smarter food choices? A small change today could make a big difference tomorrow!
