Prune Smoothie Recipe (for Stronger Bones)

👩🏽‍⚕️ Nutritionist's Note

This smoothie was built with bone health in mind, using whole foods that naturally provide calcium, magnesium, vitamin K, potassium, protein, and antioxidants.

Lightly cooking the collard greens reduces oxalates, improving calcium absorption, while still delivering vitamin K. Pumpkin seeds, chia seeds, and almond butter contribute calcium and magnesium-minerals essential for bone formation and mineralization-along with heart-healthy fats that support nutrient absorption.

Prunes add natural sweetness along with potassium, antioxidants, and unique polyphenols. Research links prune consumption to reduced bone loss, particularly in postmenopausal women. Finally, an optional clean, one-ingredient protein powder supports muscular and skeletal strength, making this prune smoothie a satisfying, food-first way to help your bones thrive over time.

👩🏼‍🌾 Ingredients & Health Benefits

As a Registered Dietitian Nutritionist, my goal is to highlight the health benefits of each ingredient. Below, I've included notes on the ingredients from a nutrition expert's perspective.

• Collard Greens: Mild when cooked, collards blend smoothly without overpowering the smoothie. They are one of the richest plant sources of calcium and vitamin K.
• Pumpkin seeds: These add a subtle nuttiness and body without changing the flavor. They contribute magnesium and plant protein.
• Almond butter: Creamy with a gentle nutty sweetness, almond butter gives the smoothie richness while adding magnesium, calcium, and healthy fats.
• Chia seeds: Nearly flavorless but transformative for texture, chia seeds thicken the smoothie and create a creamy mouthfeel. They provide calcium and magnesium.
• Nondairy Milk: Soy, pea, or hemp milk adds creaminess and a neutral base while contributing protein and, when fortified, calcium.
• Prunes: Naturally sweet and caramel-like, prunes eliminate the need for added sweeteners. They provide fiber, vitamin K, potassium, magnesium, and polyphenols that support digestive regularity and have been linked to reduced bone loss with regular intake.
• Frozen mango, berries, or banana: Use frozen mango for a naturally creamy texture and mild sweetness. Or add berries instead for a brighter, slightly tart flavor, less sugar, and to keep the smoothie tasting fresh. Alternatively, frozen banana makes the smoothie thicker and more milkshake-like, with a neutral sweetness that lets the other ingredients shine.

Optional:

• Protein powder: A clean, one-ingredient protein powder blends in seamlessly and boosts protein.
• Turmeric and Black Pepper: Turmeric's active compound, curcumin, has been proven to benefit inflammatory diseases. It adds warmth without sweetness. A pinch of black pepper enhances curcumin absorption, supporting its anti-inflammatory effects without affecting flavor.
• Cinnamon is one of the cheapest common food sources of antioxidants. I use Ceylon cinnamon to avoid the higher coumarin levels in cassia, making this smoothie safe and nourishing.

✔️ Storage Tips

These simple steps help preserve nutrients, flavor, and texture:

• Storage: Refrigerate in an airtight container for up to 4 days. This prune smoothie keeps well in the fridge due to the fiber from prunes and chia seeds. It holds its texture and does not separate or become watery over time.
