Low FODMAP Quinoa & Almond Flour Collagen Lemon Loaf

Photos and recipe by @thefodmapfactor.

This Collagen Lemon Loaf is slightly zesty, subtly sweet, and perfectly moist, with an extra bit of sweetness from a lovely lemon glaze. We make the best of a variety of Hearthy Foods' products, including our Almond Flour, Quinoa Flour, Tapioca Flour and our Grass-Fed Collagen Peptides for a boost of protein and added health benefits. This loaf is both Low FODMAP and Paleo-Friendly, making it the perfect gut-healthy, summer treat!

What are FODMAPs and what is the Low FODMAP Diet?

Standing for Fermentable Oligosaccharides, Disaccharides, and Polyls, FODMAPs are short-chain carbohydrates that are present in a variety of foods. As suggested by the acronym, these sugars are rapidly fermented by bacteria in the gut. This is fine for most people, but for those with Irritable Bowel Syndrome (IBS), consuming them can lead to digestive distress. Thus, the Low FODMAP diet was developed to help those with IBS manage their symptoms. Fortunately, research has shown that successful implementation of the diet can reduce stomach pain, bloating and distention, and improve bowel habits and quality of life.

Benefits of Dietary Collagen Peptides

As the most abundant protein in the human body, collagen is present in all connective tissues, such as skin, bones, cartilage, tendons, ligaments and blood vessels. In other words, it’s the main component of what holds the body together! It can also be found in the eyes, ears, nose cartilage, teeth, lungs, blood vessels and muscles.

Studies have shown that our collagen product can promote the reduction of wrinkles, increase hydration and elasticity of the skin, and maintain the structure and functionality of joints. It can also promote an anti-inflammatory effect, increase bone mineral density, strengthen the bones and improve the healing of ulcers.

From a gut health perspective, one study found that collagen assists in preserving the structure of the intestinal lining, preventing breakdown. It also plays a vital role in repairing the fibrosis of the gastrointestinal tract, which is an important factor in IBS management. Although it is impossible to determine in advance where collagen peptides will be used in the body once broken down into its components, the extra protein and amino acids will be utilized by your body where it's needed most - and that's a win!

Collagen Lemon Loaf Ingredients & FODMAP Content

Dry Ingredients

Hearthy Foods Almond Flour, Quinoa Flour and Tapioca Flour - Almond flour and quinoa flour make up the base of this loaf. While almond flour is mild in flavor, quinoa flour adds some uniqueness to the loaf with its very subtle grassy taste. Tapioca flour, as a finer flour, acts as a binder and gives the loaf a bit more softness than when using almond and quinoa flour alone.

According to the Monash University FODMAP Diet app, almond flour is low FODMAP in 1/4 cup servings. Quinoa flour and tapioca flour are both low FODMAP in 2/3 cup servings.

Hearthy Foods Grass-Fed Collagen Peptides - Helps to keep the loaf moist, and adds an extra boost of protein and health benefits! There are no added sugars or ingredients in our pure Collagen Peptides. So with a negligible amount of carbohydrates, there are little to no FODMAPs in our collagen.

Cream of Tartar & Baking Soda - A small amount of these ingredients encourages a modest rise after mixing and during baking.

Powdered Sugar - Used for the glaze. According to the Monash University FODMAP Diet app, powdered sugar is low FODMAP in 1 tablespoon servings and moderate FODMAP in 500g servings, which is more than 3 cups! This makes our 1/2 cup portion FODMAP-friendly. If you are Paleo, feel free to omit the glaze (the loaf is delicious on its own or with some yogurt) or substitute the powdered sugar for a homemade Paleo powdered sugar.

Wet Ingredients

Eggs - Serves as a binding element and helps the loaf rise. As eggs are mostly protein, there are little to no FODMAPs present.

Maple Syrup - Adds a little bit of sweetness, and is low FODMAP in 2 tablespoon servings. That puts 1 slice well under the FODMAP threshold.

Coconut Oil - Helps to soften and moisten the loaf.

Lemon Juice & Lemon Zest - Gives the loaf and lemon glaze its zesty & refreshing flavor. 1/2 a cup of lemon juice is low FODMAP.

Almond Milk - Used to thin out the glaze to your desired consistency, and is low FODMAP in 1 cup servings.
