1 Eat the Foodshed: Improving the Diet with Local Foods Layla Wall BS Nutrition & Dietetics: Department of Sustainability Studies Foodshed Fieldschool Participant Staple Food Advantages Some key foods that support health also store well, providing several key advantages to growers and consumers: Crops that store well allow for producers to sell their product with less possibility of spoilage before reaching market. Consumers are able to purchase local foods that can be stored and used at their convenience. Foods that store well tend to be staple foods, allowing local foods to contribute a larger amount of calories to the diet. Consumers can purchase staples and use them past the season that more perishable local foods are available. Staple Foods and Health A major health concern nationwide is type 2 diabetes, and New Mexico is not an exception. 157,000 New Mexicans have diabetes 1 Death from diabetes in NM is higher than the national average 1 The cost is over $1 billion annually in New Mexico and reduces quality of life 1. Some traditional staples can help achieve a health promoting diet to prevent disease. Meeting Nutritional Guidelines with Local Staples The Academy of Nutrition and Dietetics encourages consumption of a wide range of foods that represent a rainbow of colors. A staple in New Mexico, blue corn, is a great way to include blue food in the diet. Blue corn is a whole grain, and a source of fiber. The USDA recommends making half your grains whole, and the Academy of Nutrition and Dietetics advocates consuming adequate amounts of dietary fiber from a variety of plant sources 3,4. What are the staples in your region that have a potential to benefit health? Regional Staple Foods Every region in the world has treasured local foods that serve as staples. These foods tend to grow well in the areas they are consumed and many provide unique nutritional benefits. New Mexico staples include corn, beans, squash, peanuts, chile, pecans, and peanuts. These foods all are nutritional powerhouses that have the advantage of long shelf life. What are your regions local foods that meet the criteria of nutritious staples? What are the staples in your region that meet these criteria and how might they benefit local growers and your region’s health? References: 1.NM Department of Health. Diabetes Facts.

Staple Foods in New Mexico The three sisters, corn, beans and squash, are a traditional combination of plants that can provide inspiration for practical application of traditional food ways to today’s diet. These plants grown synergistically together, and provide protein, fiber, and micronutrients. These foods sustained people in the southwest for centuries, and have the potential to support a health promoting diet today. They store well, thus can be stored and sold when the market allows. Certain heritage varieties and production methods can bring a higher price in the marketplace for producers, while providing nutritional benefits for consumers. Why Blue Corn in New Mexico? Blue corn is a variety of Zea Mays, and is referred to as purple corn in the scientific literature. One of many colored corns that have been consumed by people in the Southwest for centuries. The corn’s pigment provides the vivid color in blue and other colored corn that serves as a possible antioxidant 2. This substance is an anthocyanin pigment, a type of flavonoid compound that gives plants various colors of blue, red, purple, and pink. A familiar source of anthocyanin pigment is blueberries. The advantage of ingesting anthocyanin pigments from blue corn for people in the Southwest is that this food is historically part of the diet, stores well without refrigeration, and is more affordable than fresh or frozen blueberries. Blue corn muffins were incorporated into the menu at La Vida Llena, a retirement community, and were well accepted by residents of many backgrounds. Blue Corn Research Recent research has identified the pigment found in blue corn to lower the total adipose tissue deposition in mice fed a high fat diet 2. The study compared the total fat deposition in a group of mice fed a high fat diet with added purple corn coloring compared to a group of mice that were fed an identical high fat diet sans purple corn coloring. The study found that the group of mice that received the purple corn coloring deposited significantly less adipose tissue, and had reduced levels of mRNA of genes involved in fatty acid synthesis 2. The mice that received purple corn coloring also had reduced indicators of insulin resistance 2. This is a metabolic condition that is often a precursor to diabetes or occurs as part of Type 2 diabetes. One major caveat is that this study subjects were mice. Perhaps future research can help determine if this outcome holds true for human subjects. Incorporating Blue Corn into Meals Use blue corn tortillas in place of flour tortillas for meals and snacks As a hot breakfast cereal: combine ¼ cup blue corn meal with ½ cup water and cook until thick Use blue corn flour in place of yellow in cornbread, muffins, and pancakes Prepared as a traditional hot drink flavored with cinnamon called Atole Blue corn popcorn Background The University of New Mexico 2011 Foodshed Fieldschool traveled throughout the Southwest to visit agricultural production sites, processing facilities, and community centers. This afforded the opportunity to learn about treasured local staple foods with unique nutritional benefits, and consider the opportunity to include them in the diet to improve nutritional intake and benefit local growers.
