Blood Sugar Basics: Warning Signs, Foods to Limit, and Common Questions About Beets

Blood sugar, also called blood glucose, is the main source of energy for your body’s cells. Keeping it in a healthy range matters for everyone, and many Americans have questions about what to eat, what to avoid, and when to talk to a doctor. This guide offers general education only. It does not replace advice from a healthcare professional.

What Is Blood Sugar?

Glucose comes from the carbohydrates you eat and drink. After a meal, your body releases insulin, a hormone that helps move glucose from the blood into your cells. When this process does not work as expected, blood sugar levels can stay higher than normal over time.

What Affects Blood Sugar Levels?

Several factors can influence blood sugar:

• Food choices: The type and amount of carbohydrates play a major role.
• Physical activity: Movement helps muscles use glucose for energy.
• Sleep and stress: Poor sleep and ongoing stress may affect how the body handles glucose.
• Body weight: Extra weight, especially around the waist, is linked to higher risk.
• Family history and age: Genetics and age can raise risk.
• Medications: Some medicines can affect blood sugar.

When Should You Be on Alert? Common Warning Signs

Certain symptoms are commonly associated with high blood sugar. Having one or more does not mean you have a condition, but they are a reason to speak with a healthcare provider:

• Increased thirst or dry mouth
• Frequent urination
• Unusual tiredness
• Blurred vision
• Slow-healing cuts or sores
• Frequent infections
• Unexplained weight loss
• Tingling or numbness in the hands or feet

Seek urgent medical care if you experience confusion, vomiting, fruity-smelling breath, rapid breathing, or extreme weakness. People who take diabetes medication should also know the signs of low blood sugar, such as shakiness, sweating, dizziness, and confusion, and follow their doctor’s guidance.

Main Foods and Drinks to Limit

Health organizations often suggest limiting foods that cause quick spikes in blood sugar or offer little nutrition:

• Sugary drinks: Soda, sweet tea, energy drinks, and sweetened coffee beverages
• Fruit juice: It lacks the fiber of whole fruit and is easy to overconsume
• Refined grains: White bread, white rice, and many crackers in large portions
• Pastries and desserts: Cakes, cookies, donuts, and candy
• Sweetened breakfast cereals and flavored yogurts: They often contain high levels of added sugar
• Fried and heavily processed foods: These can affect overall heart and metabolic health
• Processed meats: Bacon, sausages, and deli meats are often high in sodium and saturated fat
• Alcohol: It can affect blood sugar, especially on an empty stomach
• Large portions of dried fruit: The sugar is concentrated

Reading nutrition labels and checking for “added sugars” is a simple habit that helps.

Foods Often Included in Balanced Eating Plans

Many dietitians recommend focusing on:

• Non-starchy vegetables, such as leafy greens, broccoli, and peppers
• Whole grains, such as oats, quinoa, and brown rice
• Beans, lentils, and legumes
• Lean proteins, such as fish, eggs, and poultry
• Nuts, seeds, and healthy fats
• Whole fruits in reasonable portions

What About Beets?

Beets are a popular topic, and people often ask whether they are “good” or “bad” for blood sugar. Here are some general facts:

• Beets contain natural sugars, but also fiber, potassium, folate, and plant compounds called nitrates.
• Whole beets generally have a moderate effect on blood sugar when eaten in normal portions.
• Beet juice has less fiber than whole beets and may have a stronger effect on blood sugar.
• Beets can turn urine or stool pink or red, which is harmless for most people.
• Beets are high in oxalates, so people with a history of kidney stones should ask their doctor.
• Nitrates in beets may affect blood pressure, so people on blood pressure medication should check with their provider.

Beets can be part of a balanced diet, but they are not a treatment for any condition.

What About Supplements?

Some people look into supplements, such as herbal blends, chromium, cinnamon, or berberine, as part of a wellness routine. Keep these points in mind:

• Supplements are not a substitute for medical care, medication, or a healthy lifestyle.
• Results vary, and no product works for everyone.
• Some supplements can interact with diabetes medications and may cause blood sugar to drop too low.
• Dietary supplements are not evaluated by the FDA to diagnose, treat, cure, or prevent any disease.
• Never stop or change prescribed medication without your doctor’s approval.

How to Choose a Supplement Wisely

1. Talk to your doctor or pharmacist first, especially if you take medication.
2. Read the full ingredient list and check for allergens.
3. Look for third-party testing or quality certifications.
4. Review the return policy and customer support options.
5. Read independent reviews from several sources.
6. Be cautious of exaggerated claims such as “reverse diabetes,” “cure,” or “miracle formula.”
