Is 70 percent cocoa chocolate good for diabetes?

4 min read

According to a study published in The BMJ, regular dark chocolate consumption may be linked to a lower risk of type 2 diabetes. So, is 70 percent cocoa chocolate good for diabetes, and how can you enjoy it safely?

Quick Summary

Consuming 70 percent cocoa chocolate in moderation can offer potential benefits for diabetes, including improved insulin sensitivity and antioxidant intake, due to its high cocoa and lower sugar content compared to other chocolate types.

Key Points

  • Moderate Portions are Crucial: Enjoy 70% cocoa chocolate in small, controlled portions (around 1 ounce) to avoid excess calories and sugar.

  • Check the Label for Sugar: Always scrutinize the nutrition facts for added sugars, as brands and percentages vary. The benefits depend on low sugar content.

  • Benefit from Flavonoids: The high flavonoid and antioxidant content in 70%+ cocoa chocolate can improve insulin sensitivity and support heart health.

  • Choose Non-Alkalized Chocolate: Opt for dark chocolate not processed with alkali (Dutching) to retain the highest concentration of beneficial flavonoids.

  • Pair with Protein and Fiber: To minimize blood sugar spikes, pair your dark chocolate with protein and fiber sources like nuts or berries.

  • Part of a Healthy Diet: Dark chocolate is a supplemental treat, not a primary health strategy. The best approach is a balanced, healthy diet and regular exercise.

Understanding the Benefits of 70% Cocoa Chocolate

Dark chocolate with a high cocoa percentage contains several bioactive compounds that may benefit individuals with diabetes. The health properties of dark chocolate are attributed mainly to its flavonoid content, particularly flavanols. These potent antioxidants have been shown to play a role in metabolic health in several ways.

Improved Insulin Sensitivity

Research suggests that the flavanols in dark chocolate can improve the body's sensitivity to insulin. This means the body's cells can use insulin more effectively to absorb glucose from the bloodstream, which is crucial for managing blood sugar levels. Improved insulin sensitivity is a key goal for individuals with type 2 diabetes and those with prediabetes.

Heart Health and Blood Pressure

Diabetes often increases the risk of cardiovascular complications. Flavonoids in dark chocolate have been shown to support cardiovascular health by improving blood flow and reducing blood pressure. Studies indicate that consuming dark chocolate for a few weeks can lead to a decrease in both systolic and diastolic blood pressure. This protective effect is particularly valuable for people with diabetes.

Anti-inflammatory and Antioxidant Effects

Flavanols in dark chocolate have significant antioxidant and anti-inflammatory properties. Chronic inflammation and oxidative stress are linked to insulin resistance and the progression of type 2 diabetes. By combating these issues, the antioxidants in dark chocolate can help protect cells from damage and support overall metabolic health.

Lower Glycemic Impact

Compared to milk or white chocolate, 70 percent cocoa chocolate has a lower glycemic index, leading to a more gradual rise in blood sugar levels. This is because it contains less added sugar and more fiber, which helps slow down the absorption of carbohydrates into the bloodstream. The healthy fats from cocoa butter also contribute to this slower glycemic response.

The Importance of Moderation and Potential Risks

While the potential benefits of 70 percent cocoa chocolate are encouraging, it is not a free pass to overindulge. Like any other treat, moderation is critical for people with diabetes. Excessive consumption can lead to unintended consequences that counteract any benefits.

Calorie and Fat Content

Dark chocolate is still a calorically dense food due to its cocoa butter and sugar content. Overconsumption can contribute to weight gain, which is a major risk factor for worsening diabetes control. A standard 1-ounce serving (about 28 grams) is a common recommendation, but this should be factored into your daily calorie and carbohydrate intake.

Sugar Content Variation

Even 70 percent dark chocolate contains some sugar. It is crucial to read nutrition labels and understand the total carbohydrates and added sugars per serving. Brands vary significantly, with some potentially adding more sugar than others. For individuals managing blood sugar, being mindful of this is essential to prevent unexpected spikes.

Alkali-Processed Chocolate

Some chocolate is processed with alkali (also known as 'Dutching') to reduce bitterness. This process, however, can significantly lower the flavonoid content, diminishing many of the potential health benefits. Look for chocolate that has not been processed with alkali to maximize the benefits.

Comparing 70% Cocoa vs. Other Chocolate Types

Understanding the differences between chocolate varieties is key to making a wise choice for diabetes management. The cocoa content is the primary differentiator, driving variations in nutritional profile and health effects.

Feature 70% Cocoa Dark Chocolate Milk Chocolate White Chocolate
Cocoa Content High (≥70%) Low (typically <30%) None (contains cocoa butter, no solids)
Sugar Content Lower High Very High
Antioxidants Rich in flavonoids Few flavonoids None
Fiber Contains dietary fiber Very little None
Insulin Sensitivity Potential improvement Minimal impact/potential harm Negative impact
Glycemic Impact Low to moderate High Very High

Making High-Cocoa Chocolate Part of Your Diet

Incorporating dark chocolate into a diabetes-friendly diet involves more than just picking the right bar. It's about strategic consumption to minimize blood sugar impact while maximizing the enjoyment.

  • Consider Timing: Enjoying dark chocolate alongside a balanced meal or a source of protein and fiber, such as a handful of nuts or berries, can help moderate the blood sugar response. The fat and fiber slow down digestion and sugar absorption.
  • Start Small: If you are new to higher cocoa chocolate, start with a lower percentage, such as 70%, and gradually increase to 80% or 85% as your palate adapts. The richness of high-cocoa chocolate means you'll likely feel satisfied with a smaller portion.
  • Pair Wisely: Create healthy snacks by pairing a small square of dark chocolate with nutrient-dense foods. Examples include melting a piece and drizzling it over fresh strawberries or mixing cacao nibs into a yogurt bowl.
  • Listen to Your Body: Pay close attention to how your body responds. Monitoring your blood glucose levels after consuming dark chocolate can provide personalized insight into its effects on you. What works for one person may not be ideal for another.

Conclusion: A Smart Indulgence, Not a Treatment

While the prospect of a sweet treat being beneficial for diabetes is appealing, the verdict on whether is 70 percent cocoa chocolate good for diabetes is nuanced. The answer is a qualified 'yes' – provided it is consumed in strict moderation and chosen carefully. The high concentration of flavanol antioxidants offers genuine metabolic and cardiovascular benefits, such as improving insulin sensitivity and lowering blood pressure. However, dark chocolate is not a medical treatment or a weight-loss tool, and its benefits are maximized only when it is part of an overall healthy, balanced diet. By choosing a high-quality bar with minimal added sugar and exercising portion control, you can enjoy a small piece of dark chocolate thoughtfully without compromising your health goals.

Frequently Asked Questions

Yes, all 70 percent dark chocolate contains some sugar, though significantly less than milk or white chocolate. The amount varies by brand, so checking the nutrition label is always recommended.

For most people with diabetes, a small, controlled portion of about 1 ounce (28 grams) per day is considered safe. However, it is best to consult with a healthcare provider to determine the right amount for your individual health needs.

Some studies suggest that the flavanols found in high-cocoa dark chocolate may help improve insulin sensitivity, potentially benefiting blood sugar control.

When consumed in moderation, dark chocolate can be a satisfying, nutrient-dense snack that can help curb cravings. However, its high calorie and fat content mean that excessive consumption can lead to weight gain.

Enjoying dark chocolate as part of a balanced snack or meal can be beneficial. Pairing it with fiber and protein, like nuts or yogurt, can help slow the absorption of sugar and prevent rapid blood glucose spikes.
