Rice isn't just efficient at accumulating arsenic; it also can contain high levels of other heavy metals, including mercury and lead. The Mayo Clinic study included blood tests to determine levels of mercury, lead, and cadmium, and found higher levels of all three in people on a gluten-free diet.
However, researchers found that “food containing rice had significantly higher mercury concentrations than those based on wheat or other grains.” Mercury concentrations did not differ significantly between rice types—brown, unenriched white, and enriched white. Why does arsenic and mercury accumulate in rice?
This crop has been demonstrated to have agricultural challenges such as contamination with mercury. One of several known heavy metals with significant systemic toxic effects, mercury is a source of contamination of rice through environmental and occupational pollutants.
That's because rice contains inorganic arsenic, a potentially toxic metal that can cause health problems with chronic exposure.
The traditional treatment for mercury poisoning is to stop all exposures. In many cases, chelation therapy is also used. This involves giving a medication (the chelator) which goes into the body and grabs the metal (chelos is the Greek word for claw) then carries the metal out of the body, usually into the urine.
Many people consider white rice an “empty” or “bad” carb since it loses nutrients when the bran and germ are removed. However, white rice is typically enriched with added nutrients such as iron and B vitamins. So while brown rice does have more nutrients than white rice, white rice is still considered nutritious.
The FDA research also shows that rinsing rice before cooking has a minimal effect on the arsenic content of the cooked grain and will wash off iron, folate, thiamine and niacin from polished and parboiled rice.
Eat 8 to 12 ounces (two to three meals) a week of a variety of fish and shellfish that are lower in mercury. Five of the most commonly eaten fish that are low in mercury are shrimp, canned light tuna, salmon, pollock, and catfish.
Mercury and PFOS cannot be removed through cooking or cleaning -- they get into the flesh of the fish. You can reduce the amount of other contaminants like PCBs by removing fat when you clean and cook fish.
Arsenic accumulates in the grain's outer layers, which are removed to make white rice. Brown has more nutrients, though, so you shouldn't switch entirely to white. Brown basmati from California, India, or Pakistan is the best choice; it has about a third less inorganic arsenic than other brown rices.
Most rice does contain arsenic due to how it is grown in paddies, but the levels can vary depending on where the rice is from (14). Jasmine rice does contain arsenic and is in fact higher in arsenic than basmati rice (14). However, steps can be taken to reduce arsenic during the preparation of rice.
Because of its adaptability, accessibility and affordability, many people eat rice on the regular—even daily. It can certainly be part of a well-balanced meal plan.
According to Chinese mythology, rice was given as a gift from the animals after a large flood, giving the Chinese people a source of plentiful food. Rice thrived in China's wet rural environment and became the principal food staple of the region. Rice is versatile and filling, providing a satisfying meal.
The five types of foods that cause inflammation include: Red meat and processed meats, including bacon, hot dogs, lunch meats and cured meats. Refined grains, including white bread, white rice, pasta and breakfast cereals.
Basmati Is A Healthy 'Supergrain”
It contains all eight essential amino acids, folic acid, and is very low in sodium and has no cholesterol. Basmati has a low to medium glycemic index, meaning that energy is released at a slower, steadier rate leading to a more balanced level of energy.
Jasmine rice is high in carbohydrates, moderate in protein, and low in fat, making it a healthy choice for people who are looking for a filling, low-fat food. Jasmine rice is not a significant source of vitamins or minerals. But it does contain small amounts of calcium, iron, and some B vitamins.
Rinsing or washing rice removes that excess starch, resulting in grains that are more separate when cooked. (There's the added benefit that rinsing rice before cooking can reduce the level of arsenic, but FDA research shows that the impact is minimal on the cooked grain.)
Health effects of mercury exposure
The inhalation of mercury vapour can produce harmful effects on the nervous, digestive and immune systems, lungs and kidneys, and may be fatal. The inorganic salts of mercury are corrosive to the skin, eyes and gastrointestinal tract, and may induce kidney toxicity if ingested.
Once in your body, metallic mercury can stay for weeks or months. When metallic mercury enters the brain, it is readily converted to an inorganic form and is “trapped” in the brain for a long time. Metallic mercury in the blood of a pregnant woman can enter her developing child.
Salmon is low in mercury.
Farmed salmon has on average, 0.05 micrograms of mercury per gram. This is well below the levels deemed safe for women and children by the FDA and EPA, which inform the United States Dietary Guidelines for Americans (DGA).
