Understanding Lactose Intolerance Among Different Ethnic Groups
Some ethnic groups have significantly higher levels of lactose intolerance. For instance, research indicates that up to 75% of African-Americans and Native Americans, and 90% of Asian-Americans have at least some difficulty digesting milk sugar. But these aren’t the only people who might experience issues due to an imbalance of lactase in the gut. Certain digestive diseases and even minor injuries to the intestines can disrupt our enzyme balance.
The Natural Production of Lactase
The body naturally produces the lactase enzyme in the brush border of our small intestines, unless we are lactose intolerant. Lactase production is particularly high when we are infants because lactose makes up about 40% of the total calorie content of breast milk.
The Health Benefits of Lactase
The scientific community has long confirmed the use of lactase as a supplemental agent to help people properly digest lactose. Here are some significant health benefits and studies supporting the benefits of enzymes like lactase:
Lactose Intolerance
Animal-based lactase has been used for many years by people with lactose intolerance. However, increasing research on plant-based lactase shows promising evidence that it can offer similar health benefits. A review published in the 2008 “Alternative Medicine Review: A Journal of Clinical Therapeutic” found lactase to be an effective support for digestive imbalances.
Reduces Gas and Bloating
Clinical research has shown that lactase may help prevent and reduce flatulence in humans. Placebo-based studies indicate that microbial lactase preparations can significantly lower symptoms such as belching, hydrogen production, bloating, and other flatulence-related issues in individuals with reduced lactase levels in the gut.
Irritable Bowel Syndrome
The research suggests that enzymes similar to lactase may help reduce symptoms of irritable bowel syndrome (IBS). This leads to the conclusion that supplementing with lactase enzyme may benefit the estimated 1-in-5 Americans who suffer from IBS.
Digestive Upset in Children with Autism
Studies also show a correlation between chronic diarrhea in children with autism spectrum disorder and lowered amounts of intestinal disaccharidase activity, including important digestive enzymes like lactase, sucrase, and maltase.
Irritation in the Digestive Tract
Research suggests that reduced intestinal lactase enzyme activity may contribute to issues like diarrhea, illness, and other negative gut responses. Supplementing with lactase may help ease problems such as indigestion, loose stools, and sinus irritation. To prevent these issues, using lactase supplements might be a beneficial idea.
May Help Prevent Certain Digestive Issues
Scientists now understand the link between genetics and the digestive system. Some children and infants suffer from chronic diarrhea, cramping, and abdominal distension. Studies suggest that fungal-derived lactase has shown significant clinical improvements in children with these challenging digestive conditions. This research highlights the usefulness of carbohydrate enzymes like lactase in supporting digestive health associated with enzyme deficiencies.
How to Read the Units of Measurement for Lactase
Lactase (FCC ALU/g) is measured in ALUs (Lactase Units) based on the hydrolysis of carbohydrates. One ALU is calculated using a 15-minute hydrolysis of an o-nitrophenyl-β-D-galactopyranoside substrate at 37°C and pH 4.5.
The FCC notation stands for Foods Chemical Codex, a division of USP (United States Pharmacopeia), which sets standards for ingredients. In the case of enzymes, FCC is a standard assay used to accurately determine their activity. The current compendium is FCC VI.
What Is the Best Form of Lactase?
Look for a source like Veganzyme? that comes from all vegetarian, non-GMO sources, is kosher certified, contains no animal products, and is suitable for vegetarians and vegans. The best form of lactase is derived from the fermentation of A. oryzae.
