We use Jasmine Brown Rice - different brands. Never tasted like cardboard. The taste could be because you are used to high fat, sugar, salt diet and your taste buds are stuffed. Manufacturers coat the rice to stop it sticking together in the packaging. Rinsing 3x is necessary.
A quick search brings up this link about Thai rice...

There are ways to balance your blood sugar. Try a couple of tablespoons of Apple Cider Vinegar before each meal. It is said to also prevent the body laying down fat stores. Get 'Braggs' brand from Golden Place.
Add a sprinkling of Cinnamon to your rice. Half a teaspoon a day makes a big difference to your blood sugar levels. I buy packets of cinnamon sticks and grind them as needed.
Watch what sugars you are consuming. Don't eat anything with Fructose Corn syrup. Cut out the sodas completely, especially anything that says 'diet'.
If you want all the goodness of the Rice Bran, cook with Organic Rice Bran Oil. It doesn't turn toxic in high temperatures as the other oils do. Or buy 'Oryzanol' capsules.
Boozers find it hard to cut down due to sugar cravings. If you want to reduce your drinking, try eating a few sweets as you wean yourself off it.
There's little point in changing any one food (or rice) when the rest of your diet and lifestyle is unhealthy. Bit like thinking a couple of vitamin pills will correct a lifetime of abuse. Why not look at what else you are eating and make gradual improvements. If not, at least try the ACV and Cinnamon.
Good luck.
