DOCTOR’S ORDERS
Flour is essential in baking—but not all flours are created equal. Whether you're vegan, gluten-free, or simply aiming for better nutrition, here’s how your flour choices can level up your health game:
Gluten-Containing Flours:
- Whole Wheat Flour – High in fiber, B vitamins, and minerals. Great for blood sugar balance and digestion.
- Spelt Flour – Easier to digest than whole wheat and packed with nutrients.
- All-Purpose Flour – Versatile but low in nutrients; best used in moderation.
Gluten-Free Flours:
- Almond Flour – Rich in healthy fats, protein, and vitamin E.
- Oat Flour – High in prebiotic fiber for gut and heart health.
- Coconut Flour – Supports digestion and stabilizes blood sugar.
- Chickpea Flour – Protein-rich, great for heart health and plant-based diets.
- Brown Rice Flour – Good source of minerals that support your metabolism.
- Sorghum & Teff Flour – Packed with fiber and antioxidants; great for blood sugar and vascular health.
- Tapioca & Arrowroot Powder – Excellent thickeners; easy to digest but low in nutrients.
Tip from the Kitchen:
To boost the health value of your baked goods, combine whole grain and nut-based flours. For example, mix oat flour with almond flour or chickpea with brown rice flour for a more nutrient-dense and flavorful result.
And always check whether your flour substitutes require a 1:1 ratio—or if adjustments are needed for moisture or texture.
Whether you serve this pie at a gathering or enjoy a slice all to yourself, you’ll feel good knowing it’s made with real, whole ingredients—and a lot of plant-powered love.
