What is the Glycemic Index?
The glycemic index (GI) is a ranking system for carbohydrate-containing foods. It indicates how quickly a food raises blood glucose (blood sugar) levels after consumption.
Foods are ranked on a scale of 0 to 100:
- Low GI: 55 or less
- Medium GI: 56-69
- High GI: 70 or more
Low GI foods are digested and absorbed slowly, causing a gradual rise in blood sugar. High GI foods lead to faster, more dramatic spikes in blood glucose.
For people with diabetes or prediabetes, choosing more low GI foods can help control blood sugar and prevent unhealthy peaks and crashes in energy levels.
What is the Glycemic Index of Dates?
The GI rating can vary between different types and ripeness levels of dates. But most varieties are considered high glycemic:
- Medjool dates: 103
- Deglet Noor dates: 67
- Barhi dates: 70
- Saidy dates: 84
As you can see, medjool dates are very high on the glycemic index at 103. Other common varieties like deglet noor and barhi are medium GI foods.
The ripeness of the date also impacts the GI. Fully ripe, soft, sweet dates are higher GI than less ripe, firmer ones.
So are medjool dates low glycemic? No. But that doesn't mean you need to avoid them altogether if you're watching your blood sugar.
Glycemic Load of Dates
Glycemic index only tells part of the story. Glycemic load accounts for serving size by looking at the grams of carbohydrates in a typical portion.
While medjool dates are high GI, their glycemic load is medium due to their small serving size. The glycemic load of 5 pitted medjool dates (120g) is 18, which lands in the medium range.
This means portion control is key when enjoying high GI foods like dates. A few dates make a great sweet treat but won't spike your blood sugar dramatically. But overindulging in portions may cause unwanted rises in blood glucose.
Nutrition Profile of Medjool Dates
Medjool dates are more than just a sweet treat - they provide essential vitamins, minerals and antioxidants. Here is the nutrition breakdown per serving (5 dates or 120g):
- Calories: 290
- Protein: 3g
- Carbohydrates: 78g
- Fiber: 10g
- Potassium: 1,090 mg - 23% DV
- Magnesium: 54 mg - 14% DV
- Copper: 0.4 mg - 18% DV
- Manganese: 0.3 mg - 15% DV
- Vitamin B6: 0.2 mg - 9% DV
- Calcium: 64 mg - 6% DV
- Phosphorus: 62 mg - 6% DV
- Iron: 1.0 mg - 6% DV
- Antioxidants: polyphenols, carotenoids
As you can see, dates provide key electrolyte minerals like potassium, magnesium and manganese. They also contain B vitamins, antioxidants and decent fiber.
Fiber helps slow digestion, which blunts the glycemic impact of the sugars in dates. The combination of fiber, antioxidants and nutrients make dates a more nutritious choice than other candy or sweets.
7 Potential Health Benefits of Medjool Dates
Research shows dates may offer some powerful health benefits. Here are some of the top ways these sweet dried fruits may boost your wellbeing:
1. Reduce Inflammation
Chronic inflammation is linked to many diseases. The antioxidants in dates, including flavonoids, carotenoids and phenolic acids, provide anti-inflammatory activity.
Animal studies found date fruit extracts reduced several markers of inflammation and offered protection against damage caused by free radicals.
2. Support Brain Health
Neurodegenerative diseases like Alzheimer's and Parkinson's involve inflammation of the brain. The antioxidants in dates protect nerve cells from inflammation and oxidative stress.
In one study, date extracts inhibited the accumulation of amyloid beta protein, which forms the brain plaques found in Alzheimer's patients.
3. Improve Gut Health
Dates are a prebiotic food, meaning they feed the beneficial bacteria in your gut. They contain fiber that your body does not digest, allowing it to reach your colon and act as fuel for probiotics.
Better gut health can enhance digestion and immunity and reduce inflammation. More research is needed, but dates show potential as a prebiotic source.
4. Lower Triglycerides
High triglyceride levels increase your risk for heart disease. Animal studies found date fruit extract significantly decreased serum triglycerides, suggesting dates may protect heart health.
5. Reduce Oxidative Stress
Oxidative stress results from an imbalance between free radicals and antioxidants in your body. It leads to cellular damage and has been linked to cancer, aging, heart disease and more.
Thanks to their abundance of antioxidants, dates show promise for fighting oxidative stress and the chronic diseases associated with it.
6. Support Natural Labor
In some cultures, pregnant women eat dates to promote cervical dilation and reduce the need for induced labor. Some studies show date consumption in late pregnancy may reduce labor time and the need for oxytocin to induce labor.
More research is needed, but dates in pregnancy may support a quick, natural labor and delivery.
7. Help Manage Diabetes
Despite their high glycemic index, some research indicates dates may help stabilize blood sugar in diabetics. Fiber slows digestion, and antioxidants reduce inflammation and oxidative stress involved in diabetes.
One study found eating 100 grams of dates daily improved markers of inflammation and oxidative stress in diabetics. More research is needed to confirm their role in diabetes management.
How to Incorporate More Medjool Dates into Your Diet
Wondering how to eat more dates? Here are some simple ways to enjoy their sweet taste and health benefits:
- Snacking: Enjoy 4-5 pitted dates on their own or dipped in nut butter for fiber and protein
- Baking: Pure dates to use as a natural sweetener in muffins, granola bars, breads and cakes
- Smoothies: Blend dates into smoothies along with frozen fruit, milk/yogurt, and spinach or kale
- Salads: Top salads with diced dates for a flavor and nutrition boost
- Energy bites: Make no-bake energy balls
FAQs
Are medjool dates considered low glycemic?
No, medjool dates are not low glycemic. On the glycemic index, they rate at 103 which is quite high. However, due to their small serving size, their glycemic load is medium. But medjool dates are still not considered a low glycemic food.
Do dates raise blood sugar levels?
Yes, dates can raise blood glucose levels due to their high glycemic index. However, consuming just a few medjool dates as a snack should not spike blood sugar dramatically in healthy individuals. Portion control is important for people with diabetes or prediabetes.
What are the health benefits of dates?
Potential health benefits of dates include lowering inflammation, protecting brain and heart health, improving digestion, reducing oxidative stress, supporting natural labor, and helping manage diabetes symptoms. Their fiber, antioxidants, and nutrients are responsible for these effects.
