New Human Clinical Trial Confirms Glycemic Benefits for Consumers Seeking Healthier Carbohydrate Choices

January 23, 2025 – Recent human testing conducted by INQUIS Clinical Research confirms that Huckleberry Gold, a potato variety developed by the Tri-State Breeding Program and managed by the Potato Variety Management Institute (PVMI), has a low glycemic index (GI). This study builds on earlier research conducted at Montana State University (MSU), which identified Huckleberry Gold as a promising low glycemic potato based on its starch composition​.

Unlike most commonly available potatoes, which fall into the medium-to-high glycemic index range, Huckleberry Gold demonstrated a glycemic index of 52, placing it in the low GI category. Foods classified as low GI (≤55) are digested and absorbed more slowly, resulting in a gradual rise in blood sugar levels. This makes Huckleberry Gold a valuable option for individuals managing blood sugar levels, including those with diabetes, prediabetes, or metabolic health concerns​.

A Game-Changer in the Potato Market

For decades, potatoes have been associated with high glycemic responses, leading some consumers to limit their intake. However, not all potatoes are high glycemic—there exists a spectrum of glycemic indices depending on the variety, starch composition, and cooking method.

"Huckleberry Gold fills a unique niche, because it naturally falls into the low glycemic category," said Jenny Gentry, PVMI Executive Director. "Consumers now have a potato option that aligns with lower glycemic diets without sacrificing taste or versatility."

Human Testing Confirms Earlier Findings

The INQUIS study followed industry standards for glycemic index testing, using ten healthy participants who consumed Huckleberry Gold and a dextrose control in a randomized crossover design. Blood glucose levels were monitored over a two-hour period, and Huckleberry Gold consistently produced a lower glycemic response compared to high-GI foods​.

The findings support previous research from Montana State University, which identified Huckleberry Gold as one of the few potato varieties with a higher amylose-to-amylopectin ratio, a starch profile associated with slower digestion and lower post-meal blood sugar spikes​.

A Step Forward for Health-Conscious Consumers

Given the increasing focus on metabolic health, these findings open the door for Huckleberry Gold to be positioned as a functional food that supports balanced blood sugar management. Future research may further explore the metabolic benefits of incorporating low GI potatoes into daily diets.

Where to Find Huckleberry Gold

Huckleberry Gold is available through select seed growers and retailers. For more information on availability, licensing, or research collaborations, visit pvmi.org or contact Jenny Gentry, jenny@pvmi.org.
