This is what ChatGPT returned:<br \/>\nSoaking rice for 30 minutes before cooking can remove some surface starch and a small amount of arsenic, but the two effects are quite different.<\/p>\n<p>1. Arsenic removal<\/p>\n<p>Rice absorbs arsenic from the soil and water in which it grows. Much of this arsenic is inorganic arsenic, the form of greatest concern for human health.<br \/>\n&#8211; A 30-minute soak may remove some arsenic, particularly arsenic on or near the surface of the grain.<br \/>\n&#8211; However, it is not particularly effective at removing arsenic contained within the grain.<br \/>\n&#8211; Rinsing the rice several times before cooking can help, but the reduction is generally modest.<\/p>\n<p>2. Starch removal<\/p>\n<p>Here the answer is more positive.<br \/>\n&#8211; Soaking allows some loose surface starch to enter the water.<br \/>\n&#8211; Discarding that water and rinsing the rice removes the suspended starch.<br \/>\n&#8211; This can reduce the cloudy water and, to some extent, the stickiness of the cooked rice.<br \/>\n&#8211; However, most of the starch remains inside the grain.<br \/>\nResearch suggests that washing alone does not necessarily make a significant difference to the texture of cooked rice.<\/p>\n<p>3. What is the most effective way to reduce arsenic?<\/p>\n<p>The best-established household method is to cook rice in excess water, much as you would pasta, and drain it afterwards.<\/p>\n<table>\n<tbody>\n<tr>\n<th>Method<\/th>\n<th>Arsenic reduction<\/th>\n<\/tr>\n<tr>\n<td>Ordinary rinsing<\/td>\n<td>Generally small<\/td>\n<\/tr>\n<tr>\n<td>30-minute cold soak<\/td>\n<td>Some reduction, variable<\/td>\n<\/tr>\n<tr>\n<td>Cook in 6\u201310 parts water to 1 part rice, then drain<\/td>\n<td>Approximately 40\u201360%<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>The figures for excess-water cooking come from FDA research.<\/p>\n<p>There is also an interesting alternative: USDA research found that soaking white rice for 10 minutes in water at 80\u00b0C, using ten parts water to one part rice, removed an average of approximately 38% of inorganic arsenic.<\/p>\n<p>My recommendation<\/p>\n<p>If your objective is to reduce both arsenic and surface starch, I would:<br \/>\n1. Rinse the rice thoroughly.<br \/>\n2. Soak for 30 minutes in plenty of fresh water.<br \/>\n3. Discard the soaking water.<br \/>\n4. Cook in excess fresh water.<br \/>\n5. Drain when cooked.<br \/>\nOne qualification: cooking in excess water also removes some water-soluble nutrients, particularly B vitamins and iron from enriched white rice.<\/p>\n<p>Finally, I wouldn&#8217;t become overly concerned about rice consumption. Varying your grains rather than relying heavily on rice is a sensible way to reduce long-term exposure to arsenic.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>I saw this meme and thought to query the data.
