Germinated Brown Rice is one of the best sources of natural GABA (gamma-Aminobutyric Acid) an amino acid produced in the brain, which acts as a neurotransmitter ‚ a chemical that fosters communication between nerve cells ‚and helps to keep stress-related nerve impulses at bay. GABA encourages mental and emotional well being, promotes relaxation and sleep.
What is GBR?
It is simply brown rice sprouted (or germinated)! Brown rice can be easily sprouted. The brown rice is first soaked overnight (or for two days) depending on the surrounding temperature and then kept for germination. It sprouts within 12-24 hours.
Brown Rice is a whole grain and offers an excellent nutritional profile. But it is also rich in enzyme inhibitors and anti-nutrients like phytic acid. The role of these anti-nutrients and enzyme inhibitors is to bind to the minerals in the body which results in poor nutrition absorption. Antinutrients and enzyme inhibitors may also cause slight discomfort to the stomach in the form of pain or flatulence.
Reducing or removing these enzyme inhibitors and anti-nutrients is possible through traditional methods of cooking like roasting, soaking, sprouting, and fermenting. The roasting process results in the least removal of antinutrients and sprouting & fermentation offer maximum removal.
GBR is a much better option when compared to brown rice. GBR ameliorates hyperglycemia, boosts the immune system, lowers blood pressure, inhibits the development of cancer cells, and assists the treatment of anxiety disorders. GBR is a natural functional food because:
As discussed earlier, during germination, a decrease of phytic acid progresses with time. In the GBR process, not much decrease in phytate content occurs but there is a phenomenal positive change in the bioactive compounds which confers a host of benefits. Further dried GBR offers an excellent appearance, improved shelf life with more sweetness, excellent taste with better texture. It cooks easier when compared to brown rice.
When brown rice is germinated, the most significant increase in the nutrient was observed in GABA levels. GABA, a neurotransmitter is naturally found in the human brain and spinal cord which helps in preventing insomnia, depression, and headaches. A study[1] showed that intake of GABA suppressed blood pressure and improved sleeplessness. A study[2] done on mice suggested that the antidepressant-like effects produced in the mice were due to GABA. Its main benefits are listed below:
It has long been thought that GABA is unable to cross the blood-brain barrier, but recent studies suggest otherwise. There is evidence of the presence of GABA transporter in the blood-brain barrier[1]. One more study[2] suggests that the beneficial effects of GABA taken through oral supplements may be through indirect channels like Enteric Nervous System. In addition, there are hundreds of online consumers who claim the beneficial effects of GABA supplements. In any case GBR is abundant with GABA and other nutrients, and is a natural functional food which offers many benefits.

Germinated brown rice is sprouted, leading to increased nutrient bioavailability, improved digestibility, and changes in texture and taste compared to regular brown rice.
Yes, like regular brown rice, germinated brown rice is naturally gluten-free, making it a suitable option for individuals with gluten sensitivity or celiac disease.
Cooking germinated brown rice is similar to cooking regular brown rice. It typically involves rinsing the rice, using the appropriate water-to-rice ratio (typically 1 cup of rice : 2 cups of water), and simmering until the rice is tender. Follow the package instructions for the best results.
Yes, germinated brown rice can generally be used as a substitute for regular brown rice in recipes. However, keep in mind that it may have a slightly different texture and flavor profile.
