What does Dr. Gundry say about flax seeds?

4 min read

According to Dr. Steven Gundry, whole, unground flax seeds are largely indigestible and will pass through your system without providing their vital nutrients. Therefore, to reap the benefits of the powerful omega-3 fatty acids, fiber, and lignans, he insists that they must be consumed in their ground form.

Quick Summary

Dr. Gundry endorses ground flax seeds as a nutrient-dense food for gut, heart, and overall health, but warns that consuming them whole is ineffective. He recommends grinding them fresh to ensure maximum absorption of omega-3s, fiber, and lignans. His diet plan emphasizes proper preparation to unlock their full potential.

Key Points

  • Grind for digestion: Dr. Gundry insists that whole flax seeds are indigestible due to their tough outer shell, so they must be ground to be of any nutritional use.

  • Nutrient absorption: Grinding flax seeds is the only way to release and absorb their valuable omega-3 fatty acids (ALA), fiber, and lignans.

  • Fresh is best: Store-bought ground flax can be rancid. Dr. Gundry recommends buying whole seeds, grinding them fresh, and storing them in an airtight, refrigerated container.

  • Lectin-free option: Unlike chia and other seeds, flax seeds are considered safe from a lectin standpoint on the Gundry diet, specifically because their lectins are trapped within the indigestible hull.

  • Heart and gut health: Properly prepared ground flax seeds are praised for promoting cardiovascular health and improving digestive regularity due to their high fiber content.

  • Versatile superfood: Ground flax can be easily incorporated into a variety of dishes, including smoothies, baked goods, and as an egg replacer.

Grinding is Mandatory for Flax Seed Absorption

Dr. Gundry's central message regarding flax seeds is straightforward: their nutritional value is only accessible to your body when they are properly prepared. He explains that the tough outer shell of a whole flax seed is designed by nature to resist digestion, allowing the seed to pass through an animal's digestive tract unharmed so it can be dispersed and replant itself with its own 'fertilizer'. Because of this built-in protection, sprinkling whole flax seeds on your salad or mixing them into a smoothie is, in his view, a nutritional waste.

The Importance of Freshly Ground Flax

For Dr. Gundry, the optimal method involves grinding whole flax seeds at home just before use. He suggests using a simple coffee grinder for this purpose. The concern with pre-ground flaxseed from the store is its high vulnerability to oxidation. Once the outer shell is broken, the delicate omega-3 fatty acids are exposed to light and air, causing them to go rancid quickly. To prevent this, he recommends buying whole seeds, grinding only what you need, and storing any leftover ground flax in a refrigerated, airtight container. This practice ensures you are getting the freshest and most potent nutrients possible.

The Health Benefits of Ground Flax Seeds

When prepared correctly, ground flax seeds offer a wealth of health benefits that align perfectly with the principles of the Plant Paradox diet.

A Superior Source of Omega-3s

Flax seeds are a fantastic source of alpha-linolenic acid (ALA), a plant-based omega-3 fatty acid. While the conversion of ALA to the more readily used EPA and DHA is not highly efficient, particularly in men, ALA itself has numerous benefits, including reducing inflammation and supporting heart health. Adding ground flax seeds is a simple way to boost your ALA intake without relying on fish oil.

Rich in Soluble and Insoluble Fiber

Flaxseed is a fiber powerhouse, containing both soluble and insoluble fiber. The soluble fiber forms a gel-like substance in the gut, which can help regulate blood sugar levels and lower cholesterol by binding to bile salts. The insoluble fiber adds bulk to stool, promoting regular bowel movements and alleviating constipation. This dual-action fiber content is excellent for promoting a healthy and diverse gut microbiome.

Abundant Lignans for Hormonal Support

Flax seeds are the richest dietary source of lignans, which are plant compounds with antioxidant and phytoestrogenic properties. Lignans are converted by gut bacteria into enterodiol and enterolactone, which can help balance hormones. This can be particularly beneficial for postmenopausal women and offers protection against certain hormone-sensitive cancers.

Dr. Gundry's Guide to Choosing Your Seeds

Dr. Gundry is very specific about which seeds are safe on his diet, and his position on flax seeds is not an exception. Here is a comparison of flax seeds with some other popular options:

Feature Ground Flax Seeds Chia Seeds Sunflower Seeds/Pumpkin Seeds
Gundry's Status Approved (when ground) Not Recommended Not Recommended
Lectin Content Indigestible shell, so lectin is not a concern when ground. Contain lectins. Contain lectins.
Digestibility Highly digestible after grinding. Highly absorbent and can form a gel, but contain lectins. Lectins can cause issues for some.
Recommended Use Grind and add to smoothies, oatmeal, or baking. Discouraged by Gundry due to lectins. Discouraged by Gundry due to lectins.
Nutritional Profile Excellent source of ALA, fiber, and lignans. Contains omega-3s, fiber, minerals, but also lectins. Contains nutrients but also lectins.

How to Use Ground Flax Seeds on the Plant Paradox Diet

  • Smoothies: A tablespoon or two of freshly ground flax adds a creamy texture, omega-3s, and fiber to your morning drink.
  • Flax 'Eggs': For baking, combine one tablespoon of ground flax with three tablespoons of water to create a vegan egg substitute.
  • Baking: Incorporate ground flax into approved baked goods like muffins or bread for added nutrition.
  • Topping: Sprinkle ground flax on compliant cereals, yogurts, or salads for a nutty flavor and nutritional boost.

A Critical Distinction: Why Grinding Matters

In summary, Dr. Gundry’s stance on flax seeds is a lesson in nuance and proper preparation. While he affirms their status as a beneficial superfood, he draws a critical line between the whole and ground forms. The indigestible nature of the whole seed renders its prized nutrients inaccessible, while the simple act of grinding transforms it into a powerful tool for improving gut health, managing inflammation, and supporting hormonal balance. For anyone following the Plant Paradox, flax seeds are a valuable addition, but only when you remember the key rule: grind them first.

Conclusion: The Ground Flax Seed Advantage

Dr. Gundry's message is clear: the only good flax seed is a ground flax seed. By taking the small extra step of grinding them fresh, you can unlock a powerhouse of fiber, omega-3s, and lignans that supports everything from digestive health to hormone balance, making them a highly recommended component of the Plant Paradox and other health-conscious diets. Ignore this simple preparation step, and you'll miss out on the incredible benefits these tiny seeds have to offer.

Frequently Asked Questions

No, Dr. Gundry does not recommend whole flax seeds because their hard outer shell makes them indigestible, meaning your body cannot absorb the nutrients.

Yes, flax seeds are allowed on the Plant Paradox diet, but only when they are ground. Whole flax seeds are considered a waste and should be avoided.

You need to grind flax seeds to break down their tough, protective outer layer. This process allows your body to access and absorb the high-fiber content, omega-3s, and lignans locked inside.

Dr. Gundry recommends storing freshly ground flax seeds in an airtight container in the refrigerator. This protects the delicate omega-3s from oxidation caused by light and air.

While flax seeds have some lectins, Dr. Gundry considers them safe because the lectins are contained within the tough, indigestible shell that passes through the gut. Therefore, when ground, the lectins are not a concern.

Yes, Dr. Gundry has suggested mixing ground flax seeds with basil seeds as a preferable alternative to chia seeds, which he believes have problematic lectins.

Eating whole flax seeds means they will pass through your digestive system largely intact, carrying their nutrients with them and providing very little, if any, nutritional benefit.
