Topic: Tapioca
Tapioca is one of the alternative starches being used in higher end kibbles. Its gluten free, non-GMO, and when properly processed, non-toxic. In order to make, and bind kibble you must use a certain amount of starch. Tapioca is a good choice in that it is nontoxic, gluten & lectin free.
There is a lot of misinformation being disseminated about tapioca, so lets review the facts and set the record straight. There are no poisonings from properly processed tapioca flour. In fact, most poisonings occur in famine stricken areas where the starving individuals try to take short cuts in processing the raw cassava or manioc root. This is well documented. Tapioca has been safely consumed for thousands of years and is the main staple starch in African, Indonesian and South American diets. “500 million people rely on cassava as their main source of calories, among them subsistence farmers in Sub-Saharan Africa…”Richard Sayre, a professor of plant biology at Ohio State University
—-“The Culprit in Cassava Toxicity: Cyanogens or Low Protein?
by G. PadmajaThe starchy roots of cassava (Manihot esculenta Crantz) are already a staple for about 500 million people of tropical Africa, Asia, and Latin America, but countless others might also benefit from this food if it were not for the sensationalism that sometimes surrounds the crop’s potential toxicity.
The cassava plant carries two cyanogenic glucosides, linamarin and lotaustralin, in its edible roots and leaves. The amounts of these potentially toxic compounds vary considerably, according to cultivar and growing conditions. “Sweet” varieties usually have such small amounts as to be innocuous, whereas “bitter” varieties have sufficiently high levels to require domestic processing to remove most of the toxins.In situations where famine or extreme poverty may force a population to eat poorly processed cassava in a diet that is also deficient in nutrients such as protein, the plant’s cyanogenic glucosides can lead to poisoning. A classic case was the infantile kwashiorkor epidemic in famine-stricken Biafra in 1968, but there have also been recent examples of spastic paraparesis, or konzo, in drought-stricken regions of Mozambique and Tanzania.
Detoxifying cassava
Farming populations who cultivate cassava have developed many methods of detoxifying cassava. Boiling and drying are sufficient to make low-cyanogen cultivars safe for consumption, but more rigorous procedures such as grating, fermenting, and sun-drying, are necessary to effectively remove cyanogens from cultivars of higher toxicity.
The protein link
Whenever a chronic disease has been linked to cassava consumption, the victims have also been found to suffer from protein deficiency, suggesting a relationship between the two.
Protein is essential for all the body’s vital functions, and for eliminating certain dietary toxins. With the help of the enzyme rhodanese, the human body detoxifies cyanide by forming thiocyanate. When the body is regularly exposed to cassava cyanogens, the increased synthesis of rhodanese makes extra demands on the body’s reserves of amino acids, the building blocks of proteins. To detoxify 1.0 mg hydrocyanic acid (HCN), the body also needs a daily supply of about 1.2 mg of dietary sulfur (S) from S- containing amino acids (SAA). If the demand for rhodanese and SAA is prolonged, as in the regular consumption of cassava, and the diet is inadequate, the synthesis of many proteins vital for bodily functions may be impaired, leading to the development of protein deficiency diseases.
Cassava – low protein source
Cyanogens alone cannot be blamed for toxicity because other cyanogenic crops, such as sorghum and Lathyrus bean, which are widely used as food, cause few toxicity problems. But the protein contents of these two crops (11.0% and 18.7%, respectively) are higher.
Many cassava products contain very low amounts of cyanogens, which can be efficiently eliminated by the body, if the protein intake is adequate. Cassava roots, being bulky and rich in carbohydrates, free dietary proteins from having to meet the body’s energy needs, thus allowing them to be used more efficiently. However, the level of protein in cassava lags far behind the levels found in rice, wheat, and tuber crops (Figure 1). An adult consuming 1 kg of cassava has to ingest 52 g of protein from other sources to obtain the U.S. recommended daily allowance (RDA) of 65 g protein per adult. In contrast, 1 kg of wheat supplies 121 g of protein and rice, 61 to 64 g of protein.
If protein intake is more than adequate for both general metabolic requirements and cyanide elimination, toxic effects are lessened or even eliminated, even if cassava is improperly processed. (Fatal poisoning can result from ingestion of large amounts of unprocessed or poorly processed high-cyanogen cassava.) Hence, the lack of protein in cassava roots is probably responsible for most non-fatal cases of cyanide poisoning associated with cassava.”

Notice it was cassava and not tapioca, that caused the poisonings. Notice also that they weren’t in the US, but in impoverished areas, in developing nations, and there was a lack of sufficient dietary protein.
——-Nutritional profile of cassava
Cassava root is essentially a carbohydrate source.[27] Its composition shows 60â65 percent moisture, 20â31 percent carbohydrate, 1â2 percent crude protein and a comparatively low content of vitamins and minerals. However, the roots are rich in calcium and vitamin C and contain a nutritionally significant quantity of thiamine, riboflavin and nicotinic acid. Cassava starch contains 70 percent amylopectin and 20 percent amylose. Cooked cassava starch has a digestibility of over 75 percent.
Cassava root is a poor source of protein. Despite the very low quantity, the quality of cassava root protein is fairly good in terms of essential amino acids. Methionine, cysteine and cystine are, however, limiting amino acids in cassava root.

——THE HEALTH BENEFITS OF TAPIOCA
Aug 5, 2011 | By Kristi WrayConventionally, tapioca, derived from the cassava plant, is best known as a creamy pudding dessert with little sustenance. However, in some in areas like Africa, Asia and South America, tapioca is known better for its nutritional benefits than as a sweet treat. When eaten raw or incorrectly prepared, the plant releases poisonous properties. Thus, tapioca must be prepared correctly to prevent harm and ensure safe eating.
STARCH EQUALS ENERGY
The cassava plant is a root vegetable and a healthy source of carbohydrates. In many countries, it serves as a main dish because of its high starch content. Even better, it is considered a healthy starch because it is low in cholesterol and unhealthy fats. Tapioca can be included in dietary plans to promote healthy weight gain.GLUTEN-FREE
People suffering with Celiac disease or other conditions that restrict the use of gluten-based foods can use tapioca as an alternative to recipes that use wheat flour. Tapioca flour, which does not contain any gluten, is a healthier alternative to wheat flour. Both tapioca flour and tapioca starch can be used as a thickening agent in cream-based sauces and gravies.MINERALS
Calcium, phosphorous, potassium and magnesium can be found in tapioca in varying amounts. If you are preparing a more processed form of the root, like a pudding mix, you will receive a smaller amount of these minerals than if you were to consume tapioca starch or flour. Tapioca is also a good source of iron, and, in particular, dry tapioca pearls contain up to 13 percent of your daily value of iron. B-vitamins, including folic acid, which is extremely vital for pregnant women, are also found in tapioca.DIETARY FIBER
Over the years, the U.S. Department of Agriculture has placed extreme importance on the consumption of dietary fiber on a daily basis for a healthier lifestyle. The cassava root has a significant amount of dietary fiber in its natural form. According to the USDA, foods high in dietary fiber can help lower cholesterol, decrease the rate of colon cancer, and lower the risk of diabetes and heart disease.” http://www.livestrong.com/article/509033-the-health-benefits-of-tapioca/
