Understanding Diabetes: The Basics
Diabetes affects over 9% of the population, with thousands of new cases diagnosed daily. Despite its prevalence, confusion and myths about diabetes persist—making it harder for those living with the condition to manage it effectively. Diabetes is broadly divided into two types:
- Type 1 Diabetes: The body cannot produce insulin and requires insulin therapy.
- Type 2 Diabetes: The body develops insulin resistance. This is more common and often linked to lifestyle factors, but genetics also play a significant role.
This article addresses the seven most common myths about diabetes, as discussed by leading nutritionists and medical experts. Each myth is debunked with evidence-based information to help you distinguish fact from fiction.
Myth #1: Overweight People Always Develop Diabetes
Reality: Obesity is a major risk factor for type 2 diabetes, but not everyone who is overweight gets diabetes—and not all people with diabetes are overweight2.
- About one third of obese individuals have diagnosed diabetes; others may never develop it.
- Genetics, age, ethnicity, and lifestyle also influence diabetes risk, not just weight.
- Type 1 diabetes is not related to weight—it usually develops due to autoimmune causes.
If you’re concerned about your risk, regular screenings are recommended—especially for those over 45 or with additional risk factors.
Myth #2: Diabetics Must Always Carry Snacks
Reality: The need to carry snacks depends on the type of diabetes and medication2.
- For type 1 diabetes, quick sugar sources are essential, as hypoglycemia (low blood sugar) can be sudden and dangerous.
- For type 2 diabetes, snack needs vary by medication. Those on drugs that can lower blood sugar (like insulin or sulfonylureas) may need to carry snacks; those managing by diet alone usually do not.
- Nutritionists recommend a shelf-stable snack of around 15 grams of carbohydrates for emergencies, such as a granola bar or fruit.
The real key to managing diabetes is eating regular, balanced meals—never going too long without food.
Myth #3: Only Older People Get Diabetes
Reality: While type 2 diabetes used to be called ‘adult-onset,’ it’s now seen in children as young as 3 years old2.
- Over 5,000 children develop type 2 diabetes every year in the U.S.
- Type 1 diabetes can occur at any age, and cases in young adults and adults are rising.
- For type 2, age 45–64 remains the most commonly diagnosed group, but increased childhood obesity has led to more cases in kids and teens.
If you have a family history or risk factors, regular screening is vital—no matter your age.
Myth #4: Diabetes Treatment Is Only Medicine and Diet
Reality: Exercise is a critical part of diabetes management—not just medicine and diet2.
- Regular movement, even simple walking, helps your body respond better to insulin and can lower blood sugar.
- The recommended goal: 10,000 steps per day. While this seems high, breaking it into short walks makes it achievable.
- Activities like swimming, cycling, or dancing also support good glucose control.
Consult your healthcare professional before starting new exercise regimes—it’s especially important if you take medications that could cause low blood sugar.
Myth #5: Type 2 Diabetes Results from Eating Too Much Sugar
Reality: Eating sugar alone does not cause diabetes, but an unhealthy diet can contribute—as can genetics, smoking, and inactivity2.
- Type 2 diabetes develops from a combination of genetic and lifestyle factors, not just sugar intake.
- Refined carbohydrates and sugary foods may increase risk, but they are only part of the picture.
- Screening tests, including fasting blood glucose and HbA1c, help evaluate your long-term risk.
A balanced diet, regular exercise, and regular health checks offer the best prevention.
Myth #6: Diabetics Can’t Eat Fruit
Reality: Fruits are nutrient-rich and safe for most people with diabetes when eaten in moderation2.
- Fruit contains vital vitamins, minerals, and plant compounds that support overall health.
- Nutrition experts advise pairing fruit with a protein source: nut butter, low-fat cheese, or hard-boiled egg, for steadier blood sugar levels.
- The real concern is portion control and awareness of carbohydrate content—not avoidance.
Focus on whole fruits over fruit juices or dried fruit, which are higher in sugar and calories.
Myth #7: Diabetes Is Always Caused by Poor Lifestyle Choices
Reality: Type 1 diabetes is autoimmune and not related to lifestyle; type 2 has many causes2.
- Type 1 diabetes occurs when the body attacks its own insulin-producing cells. The cause is unknown and not related to diet or exercise.
- Type 2 diabetes is more likely with poor diet and inactivity, but family history, ethnicity, and other health conditions also matter.
Healthy choices help prevent type 2 diabetes, but individuals should never be blamed for their diagnosis.
Frequently Asked Questions (FAQs)
Q: Can people with diabetes eat sugar?
A: Yes, but moderation is key. People with diabetes do not need a sugar-free diet, but they do need to monitor their overall carbohydrate intake and focus on a balanced nutrition plan.
Q: Is diabetes a mild disease?
A: No. All forms of diabetes are serious and, if not properly controlled, can lead to complications such as heart disease, kidney problems, and nerve damage.
Q: Are special foods needed for diabetes?
A: No special ‘diabetes foods’ are required. A healthy, balanced diet low in fat, salt, and sugar is best. Fresh fruits, vegetables, whole grains, lean proteins, and healthy fats are all encouraged.
Q: Does everyone with diabetes need insulin?
A: Not everyone. All people with type 1 diabetes require insulin. Many with type 2 diabetes can manage with oral medication, lifestyle changes, or both, though insulin may still be needed as the disease progresses.
Q: Is it possible to reverse diabetes?
A: There is no cure for type 1 diabetes. Some people with type 2 diabetes can achieve remission through substantial lifestyle changes, but continued monitoring and management remain necessary.
