Is White Rice Healthy Is White Rice Healthy?
culled from:

White rice. It is a controversial food in nutrition circles. On the one hand, some nutritionists call it an empty source of calories and recommend avoiding it. Others consider it a safe starch and say it is ok in moderation.
Then, of course, there is the Japanese paradox- also known as “they eat rice all the time and live a long time so I should be able to eat pizza and Doritos and live to be 100 too” (exaggeration but I’ve heard some arguments very close to that)
Unlike modern wheat, which has been hybridized and modified and can be problematic for many people, and most other grains, rice is unique and potentially less harmful. I get asked about rice often and felt that it deserved its own post.

White Rice vs. Brown Rice

Brown rice is often considered a healthier rice than white rice, but white rice may actually be the healthier choice. Like anything from the grains family, rice contains a certain level of anti-nutrients like phytates which can make it hard for us to absorb the minerals it contains.
When my husband and I were working to reverse our cavities (we were able to), we had to avoid foods that were high in phytic acid, and brown rice was on this list because of its phytic acid content.
White rice, was considered safe in moderation. The reason is that when rice is milled, the bran is removed. This is the process that makes the rice “white” instead of brown, but since it removes the bran, it removes almost all of the phytic acid. This makes the rice more digestible and cuts down on the grain based fiber (which can be harmful to the gut).
Brown rice technically has more nutrients, but they aren’t available to the body and the bran is the most problematic part of the rice as far as phytic acid content. In fact, white rice is lower in phytic acid than most nuts, seeds and definitely most other grains.

Arsenic in Rice?

A few years ago, research came out warning against rice consumption because it could contain high levels of arsenic. Arsenic levels were significantly higher in brown rice than in white rice because arsenic is often found in the bran, which is removed in white rice. Chris Kresser explains:
Brown rice, on the other hand, has significantly more arsenic than white rice and should be avoided or consumed rarely. Some of the brown rice brands tested contained at least 50% more than the safe limit per serving, and a few even had nearly double the safe limit. (PDF with complete details of test results) Note that some of the worst offenders for arsenic are made from brown rice: processed rice products like brown rice syrup, brown rice pasta, rice cakes and brown rice crisps. These processed products are commonly consumed by those following a “healthy” whole grain rich or gluten-free diet, but they clearly pose a significant risk of arsenic overexposure, especially if a person eats more than one serving per day. Obviously, brown rice is not a food that should be a dietary staple, or even eaten on a regular basis.
The lowest levels of arsenic were found in white rice (jasmine or basmati) that was imported from other countries. Rinsing the rice (traditionally done in many cultures) further reduced the arsenic levels. There is still controversy on the rice/arsenic connection but this is one of the reasons we don’t consume rice often.

Naturally Gluten Free…

Rice is naturally gluten free, so the most problematic part of many grains is already absent from rice. This makes it generally a safe choice for celiacs and those who are gluten intolerant, but doesn’t mean it is healthy.
At the same time, many people do need some sources of healthy carbs and rice can be a relatively safe option. Women especially often see negative effects on hormones from consuming too low carb of a diet for too long, and of all the grains, white rice is a generally safe option for safe carb consumption.

Rice and Diabetes Link?

A 2012 study claimed that white rice consumption was associated with a higher risk of Type 2 diabetes, and this if often used as a reason to avoid rice. I was surprised by this study when it first came out since historically, Asian countries with high consumption of white rice still had low incidence of diabetes.
I researched further and realized that the study was just showing an association between “risk” of diabetes and rice consumption and not actual incidence of diabetes. Paul Jaminet (author of The Perfect Health Diet) provides a better explanation for the research:
If anything, diabetes incidence goes down as rice consumption increases. Countries with the highest white rice consumption, such as Thailand, the Philippines, Indonesia, and Bangladesh, have very low rates of diabetes. The outlier with 20% diabetes prevalence is the United Arab Emirates. A plausible story is this:
  1. Something entirely unrelated to white rice causes metabolic syndrome. Possibly, the something which causes metabolic syndrome is dietary and is displaced from the diet by rice consumption, thus countries with higher rice consumption have lower incidence of metabolic syndrome.
  2. Fact: Diabetes is diagnosed as a fasting glucose that exceeds a fixed threshold of 126 mg/dl, and in those with metabolic syndrome (but not those without) higher carb consumption leads to higher fasting blood glucose.
  3. Therefore, the fraction of those with metabolic syndrome diagnosed as diabetic will increase as their carb consumption increases.
  4. In China and Japan, but not in the US and Australia, white rice consumption is a marker of carb consumption. So the fraction of those with metabolic syndrome diagnosed as diabetic will increase with white rice consumption in China and Japan, but will be uncorrelated with white rice consumption in the US and Australia.
This chart (source) shows actual rates of diabetes compared to white rice consumption. If anything, it indicates that actual incidence of diabetes was lowest in countries with high consumption of white rice: White rice consumption and diabetes Is White Rice Healthy?

What Do the Experts Say?

Rice is a surprisingly polarizing food among nutrition experts, but here is where some experts weigh in on rice:

My Opinion

At the end of the day, I consider rice to be in its own category. It doesn’t deserve the same label as most grains (especially modern grains) and it certainly isn’t as bad on the nutritional spectrum as foods like vegetable oils. The safety of rice consumption seems to vary greatly based on the individual, cultural background and what the rest of the diet looks like.
For those already consuming a diet high in other carbohydrates and low in minerals, rice (or any grain) is definitely not the best option. Those on a high nutrient diet devoid of inflammatory foods and who have an active lifestyle may do great with moderate rice consumption. Of all the grains, rice is definitely the safest option and the only one I recommend consuming.
Personally, our family consumes organic white jasmine rice occasionally (once a week or less).
We typically consume it on heavy workout days or after a lot of activity and always in conjunction with high nutrient foods. I pre-rinse it to help remove any remaining arsenic. I don’t consider it a “cheat” food because the idea of “cheating” goes against our food rules and our goal to create positive and healthy attitudes about food with our kids. It is a food that we eat occasionally but not everyday since white rice isn’t an exceptional source of nutrients but it also isn’t as potentially harmful as many other grains.
I love occasionally enjoying some high quality sushi after a workout or some rice in a stir fry but don’t consider it a staple food. Rice still can contain trace amounts of arsenic so it certainly isn’t one of the first foods I feed to my babies and I avoid any processed foods with rice since these may be higher in arsenic.
