Key Takeaways
- Flaxseeds are one of the best plant sources of omega-3s, which are good for heart health.
- Flaxseeds can help lower LDL cholesterol and reduce inflammation.
- Hemp seeds are a top choice for protein.
Flax and hemp seeds may be small, but they’re loaded with nutrients. Both provide healthy fats, protein, fiber, and beneficial plant compounds. That said, flaxseeds stand out for heart health thanks to their higher omega-3 content.
Flaxseeds Are Very Rich in Omega-3s
Flaxseeds are one of the best plant sources of alpha-linolenic acid (ALA), a type of omega-3. About 50%-60% of the fat in flaxseeds comes from ALA, giving them a great omega-6 to omega-3 balance.
Studies show that eating flaxseeds can help lower “bad” LDL cholesterol, reduce inflammation, and protect your heart.
Hemp seeds also have ALA, but less—around 15%-26% of their fat. They still offer a healthy fat balance and protein, fiber, and plant compounds that may support heart and blood vessel health.
Flaxseeds vs. Hemp Seeds: Nutrition at a Glance
Here’s how flaxseeds and hemp seeds compare nutritionally:
| Flaxseed vs. Hemp Seeds | ||
|---|---|---|
| Nutrients | Flaxseed | Hemp |
| Serving Size | 1 tablespoon | 1 tablespoon |
| Calories | 37 | 57 |
| Fat (grams) | 3 | 5 |
| Protein (grams) | 1 | 3 |
| Carbohydrates (grams) | 2 | 1 |
| Fiber (grams | 2 | 0.5 |
Beyond omega-3s, flaxseeds are high in soluble fiber, which helps with digestion, keeps blood sugar steady, and can lower cholesterol. They’re also rich in lignans, plant compounds that act like antioxidants and may support heart and hormonal health.
Hemp seeds stand out as a top protein choice. They contain all nine essential amino acids, making them a complete protein similar in quality to eggs. They’re also rich in minerals like magnesium, iron, and zinc, and provide vitamins E, D, and A. Hemp seeds are less fibrous than flaxseeds, but still add some gut-supporting nutrients.
Do They Offer Any Other Health Benefits?
1. Anti-Cancer and Anti-Aging Properties
Flaxseeds are notable for their lignans, which may help lower the risk of certain cancers, especially hormone-related types. Their fiber and omega-3s also support healthy aging and gut health.
Hemp seeds provide antioxidants and reduce inflammation, but research on cancer prevention is stronger for flax.
2. Protein and Muscle Health
Hemp seeds are packed with protein that’s complete and easy to digest. They can help support muscle repair and growth, making them a solid choice for anyone on a plant-based diet.
Flaxseeds provide some protein too, but in smaller amounts and without all the essential amino acids.
3. Gut Health
Flaxseeds’ soluble fiber feeds healthy gut bacteria, supports regular bowel movements, and helps regulate blood sugar and cholesterol.
Hemp seeds can help gut health too, supporting the gut barrier and reducing inflammation, but they’re lower in fiber.
How to Add Flaxseeds and Hemp Seeds to Your Diet
Both seeds are easy to add to your diet:
- Flaxseeds: Use ground flaxseeds for the best absorption. Sprinkle them on oatmeal, yogurt, or smoothies, mix into muffins or pancake batter, or stir a small amount into soups and stews. Whole flaxseeds are fine for crunch in granola, but may pass through undigested.
- Hemp seeds: These have a mild, nutty flavor and can be eaten raw. Add them to salads, smoothies, yogurt, grain bowls, or avocado toast. They can also be blended into sauces or homemade energy bars.
