Known health risks

Several studies have linked the consumption of flour contaminated with traditional canaryseed silica fibers to esophageal cancer. Pureza sells only Silica Fiber Free™ canaryseed. These “hairless” or glabrous types of canaryseed, developed by the University of Saskatchewan, lack these silica fibers.

Consumer protection

For the well-being of consumers, the US Food and Drug Administration (FDA) does not permit dietary supplement providers to discuss a product’s potential or known health benefits as related to a disease or condition. This is out of concern that people who may need to seek medical treatment might instead use products that have not undergone extensive testing for safety and effectiveness. Such a delay in seeking effective treatment could be harmful.

With this in mind, Pureza does not discuss specific diseases or health conditions on our website. We focus instead on the nutritional properties of Silica Fiber Free™ alpiste that may support normal health.


Use of canaryseed as a dietary supplement has surged worldwide in recent years, fueled largely by the personal stories of people who have used it. Some people use canaryseed milk or leche alpiste to support normal health of the heart, blood vessels, liver, kidneys and pancreas. Others claim it helps them maintain a healthy weight.

Please note, however, that although researchers have intermittently studied the nutritional properties of canaryseed since the 1960’s, only recently have they begun investigating its possible health benefits for humans. So these popular uses are not substantiated by scientific data.

Based on our own survey of the scientific literature, we believe these nutritional properties have potential value in Silica Fiber Free™ canaryseed used a dietary supplement:

Antioxidant activity
One 2004 study found canaryseed has antioxidant activity close to that of vitamin C. Plant sterols and certain esters of caffeic acid (which is unrelated to caffeine) may contribute to canaryseed’s antioxidant activity.

Protein and amino acids
Canaryseed has 9 grams of protein per 5 tablespoon serving (measured dry). This is 18% of the US Recommended Daily Allowance. Analysis of canaryseed protein found proportionately high levels of the amino acids arginine, tryptophan and phenylalanine, as well as a high arginine/lysine ratio.

Digestion and nutrient absorption.
Many people, notably the Raw Foodists, believe that eating enzyme-rich foods promotes digestion and health. Cooking plant foods destroys many if not most of these enzymes. Since canaryseed grain is soaked and consumed raw, it has these active enzymes in it.
