Foods Providing Glutathione
Foods Providing Glutathione – Glutathione is found pre-formed in many foods, even though it is found in relatively small amounts. Asparagus and avocado are near the top of the vegetable list when it comes to glutathione content. However, since a healthy human body can make glutathione from its three building blocks (the amino acids glutamic acid, glycine, and cysteine), it is only necessary to eat foods that contain these three individual amino acids and a healthy body can figure out how to combine them into glutathione. Cysteine is usually considered the most important of these amino acids to obtain from the diet when it comes to formation of glutathione, and you can find this sulfur-containing amino acid in most cruciferous vegetables (like broccoli, Brussels sprouts, cauliflower, kale and more) as well as onions and garlic.
While it is true that digestive enzymes are capable of breaking proteins down into individual amino acids, they don’t always do so. The body is capable of absorbing whole proteins intact, and a relatively tiny piece of protein like glutathione can also be absorbed intact.
In practice, it turns out that the body doesn’t often choose to absorb glutathione intact and prefers to break it down, absorb its separate amino acids, and then re-assemble them into glutathione as needed.
Health-e-Solutions comment: The Roman Diet should provide plenty of the basic building blocks required by the body to produce glutathione. However, if your health is seriously compromised, you should talk to your medical professional to see if glutathione supplementation is right for you.
