Can Your Body Digest Wheatgrass? The Surprising Truth

4 min read

According to nutritional experts, humans lack the enzymes to break down the tough cellulose in raw grass, making a mouthful of plain wheatgrass indigestible. This leads to the critical question: can your body digest wheatgrass effectively and absorb its celebrated nutrients?

Quick Summary

Humans cannot digest raw wheatgrass leaves due to their high cellulose content. However, juicing or powdering the grass breaks down the fibrous cell walls, making its concentrated vitamins, minerals, and chlorophyll readily available for the body to absorb.

Key Points

  • Indigestible Cellulose: The human body lacks the enzyme cellulase needed to break down the tough cellulose fibers in raw wheatgrass.

  • Juicing is Essential: To absorb its nutrients, wheatgrass must be juiced or powdered, which breaks down the fibrous cell walls.

  • Rich in Nutrients: Juiced wheatgrass is a concentrated source of vitamins, minerals, enzymes, and chlorophyll that the body can easily absorb.

  • Aids Digestive Health: Wheatgrass juice contains digestive enzymes that can help break down food and improve nutrient absorption in the gut.

  • Start Slowly to Adjust: Beginners should start with small doses of wheatgrass juice to acclimate to its potent detoxifying effects and minimize potential side effects like nausea.

  • Fresh vs. Powdered: While both are effective, fresh wheatgrass juice is generally considered more potent due to higher levels of active enzymes.

Understanding the Raw Challenge: Why You Can't Eat Raw Wheatgrass

The most straightforward answer to the question "Can your body digest wheatgrass?" is that you cannot digest it in its raw, fibrous form. The human digestive system is simply not equipped for it. The primary reason lies in a specific type of carbohydrate called cellulose, which makes up the cell walls of plants like wheatgrass.

Unlike cows and other ruminants, humans do not produce the enzyme called cellulase, which is essential for breaking down the tough cellulose fibers. This biological limitation means that chewing and swallowing raw wheatgrass would result in the material passing through your digestive tract largely undigested, and you would not be able to absorb most of the nutrients locked inside. This is why wheatgrass is almost always consumed in processed forms, such as juice or powder.

The Juicing Solution: Unlocking the Nutritional Power

Juicing wheatgrass is the key to bypassing the indigestible cellulose. A juicer crushes and presses the wheatgrass, effectively breaking open the plant's cell walls and releasing its nutrient-rich liquid contents. This liquid, or juice, is packed with vitamins, minerals, enzymes, and chlorophyll, all of which are easily absorbed by the human body. This process makes the potent nutrients bioavailable, meaning your body can readily use them for its benefit. A single shot of wheatgrass juice is often compared to a significant amount of dark, leafy greens due to its concentration of nutrients.

Comparing Raw Wheatgrass vs. Juiced Wheatgrass

Feature Raw Wheatgrass (Chewing) Juiced Wheatgrass
Digestibility Very difficult; cellulose is indigestible. Easily digested and absorbed.
Nutrient Absorption Minimal, as nutrients are locked in cell walls. High, as nutrients are released from cell walls.
Primary Benefit Minimal nutritional benefit; acts as a fiber source. Access to concentrated vitamins, minerals, and enzymes.
Taste Strong, fibrous, and difficult to chew. Potent, grassy flavor, often mixed with other juices.
Digestive Impact May cause discomfort due to high, unprocessed fiber. Can aid digestion and detoxify the gut with beneficial enzymes.

The Role of Enzymes in Digesting Wheatgrass Juice

Once the wheatgrass is juiced, the focus shifts from the indigestible fiber to the rich enzymatic content of the liquid itself. Wheatgrass juice is a source of various digestive enzymes, such as protease and lipase, that can actually aid your body's own digestive process. These enzymes help break down food and improve the absorption of nutrients, not just from the wheatgrass but from other foods consumed as well. This can lead to reduced bloating, gas, and stomach upset for many individuals. Drinking wheatgrass on an empty stomach is often recommended to maximize the absorption of these beneficial enzymes.

How to Maximize the Benefits of Wheatgrass Consumption

  • Start with Small Doses: For first-time consumers, a small 1–2 ounce shot is recommended to allow the body to adjust to its potent detoxifying effects. Side effects like nausea or headaches can occur initially, but often subside within a couple of weeks.
  • Choose Fresh Juice Over Powder: While powdered wheatgrass is convenient, fresh juice is considered to be significantly more potent and effective, as it retains more of its active enzymes and nutrients.
  • Mix for Palatability: If the earthy, grassy taste is too strong, mix the wheatgrass juice with other fruit juices, coconut water, or add it to a smoothie.
  • Consider Capsule Form: For those who cannot tolerate the taste, wheatgrass is also available in capsules or tablets.
  • Grow Your Own: For the freshest and most potent juice, consider growing and juicing your own wheatgrass at home, though it's important to ensure it's free of mold.

Potential Side Effects and Considerations

While wheatgrass is generally safe for most people, some individuals may experience adverse reactions, especially when they first start consuming it. These can include nausea, headaches, or stomach upset due to its potent detoxifying properties. It's crucial to consult a healthcare professional before adding wheatgrass to your diet, particularly for pregnant or breastfeeding women, or those with underlying health conditions. For individuals with celiac disease or gluten sensitivity, it is important to choose certified gluten-free products, although wheatgrass itself is gluten-free as long as it is harvested before the wheat seed forms.

Conclusion

So, can your body digest wheatgrass? The answer is nuanced. While your body cannot break down the raw, fibrous leaves, it can effectively digest and absorb the wealth of nutrients when consumed in a juiced or powdered form. The key is processing the grass to release its powerful nutritional components, including chlorophyll, vitamins, minerals, and digestive enzymes, which can support overall health. By understanding the difference between raw and processed wheatgrass, you can safely and effectively incorporate this potent superfood into your diet.

Frequently Asked Questions

Humans cannot eat raw grass because our digestive systems do not produce the enzyme cellulase, which is necessary to break down the cellulose that forms the tough cell walls of grass.

The best way to consume wheatgrass is by juicing it, or using it in a powdered form mixed with water or other liquids. This breaks down the indigestible fibers and releases the concentrated nutrients for your body to absorb.

Yes, especially for new users. The potent detoxifying properties of wheatgrass can sometimes cause temporary side effects like nausea, headaches, or stomach upset. It's recommended to start with a small amount and increase gradually.

Yes, pure wheatgrass is gluten-free. Gluten is found in the wheat kernel, but wheatgrass is harvested before the seed head forms. However, those with celiac disease should ensure they are using certified gluten-free products to avoid cross-contamination.

Yes, wheatgrass juice is known to aid digestion. It contains beneficial enzymes that help break down food and its detoxifying properties can cleanse the gastrointestinal tract, which may reduce issues like bloating and constipation.

The time it takes to see benefits can vary by individual. Some people report experiencing increased energy and better digestion within a few weeks, while others with more chronic conditions may take longer to notice effects.

Fresh wheatgrass juice is considered more potent with higher levels of active enzymes. Powdered wheatgrass, while more convenient and shelf-stable, has undergone processing that may reduce its enzymatic activity.
