Protein-rich. Low-carb. Gluten-free. These are all popular eating plans today. And peanut flour can help you achieve each of these diet goals.1, 2, 3, 4 That’s because peanut flour is:
- Rich in protein. Peanut flour is made from crushed peanuts that have had some of their fat removed. 4, 5 What’s left is a concentrated source of high-quality protein.6 In fact, peanut flour has 11 to 17 grams of protein per ¼ cup of flour1, 2, versus 3 grams for white all-purpose flour made from wheat.7
- Low in carbohydrate. The higher protein content of peanut flour is balanced out by a lower carb content. Peanut flour has 9 to 11 grams of carbs per ¼ cup of flour1, 2, versus 24 grams for wheat flour.7
- Gluten-free. Gluten is a type of protein found in wheat, barley, rye, and sometimes oats that can cause health issues in people with gluten intolerance, wheat allergy, or celiac disease.3 Peanut flour doesn’t contain this protein, so it’s a good option for people on a gluten-free diet.3, 4
The Power Flour for Your Heart
Peanut flour contains several compounds that have been linked to better cardiovascular health.8 It’s packed with arginine2, 8, an amino acid involved in helping keep arteries relaxed and blood flowing freely.5 Plus, it contains phytosterols, plant compounds that help with maintaining healthier cholesterol levels.5
In one study, USDA researchers fed hamsters one of four different diets:
- A diet that contained fat-free peanut flour
- A diet that contained peanut oil
- A diet that contained peanuts
- A peanut product–free diet (the control group)8
After six months, the three groups that ate peanut products had lower LDL, or “bad,” cholesterol levels than the control group.8 The development of atherosclerosis (the buildup of fatty deposits inside arteries9) was also slowed in the three peanut groups.8
Nutty Flavor Is a Baked-In Feature
In addition to having health benefits, peanut flour adds a delicious nutty flavor to baked goods and main courses.4 In baking, peanut flour is often combined with another type of flour to achieve the best result.5, 10 Since peanut flour does not contain gluten, baked goods made with a combination of peanut flour and another flour may rise better than those made with peanut flour alone.10
One study looked at the ideal ratio of peanut flour to white wheat flour for baking bread.10 Volunteers rated the taste best when peanut flour replaced about half of the wheat flour (as measured by weight) in a bread recipe.10 However, the bread rose higher the less peanut flour was used10 When adapting your own favorite baking recipe, you may need to experiment a bit to find the right mix of flours.
Of course, you could also just look for new recipes that already include peanut flour as an ingredient. You’ll find Peanutty Zucchini Muffins, Rocky Road Brownies with Peanuts, and Peach Berry Crisp with Oatmeal-Peanut Topping among our recipes for Baked Goods and Desserts.
