Discover the Ancient Art of Drying Food for Healthy Snacks

By Scout Nelson

Drying food is one of the oldest and easiest ways to preserve it for later use. People first learned this method by watching animals eat dried berries and survive, long before science explained how removing water slows spoilage. By lowering the water activity, drying stops bacteria, mold, and yeast, keeping food safe and nutritious for months.

Removing water also concentrates natural sugars and calories. For example, one cup of grapes has about 60 calories, but a cup of raisins has more than 490 calories. Both are healthy, but dried fruit is more calorie dense, so portion size matters.

Ancient cultures around the world relied on dehydration. Early Native Americans perfected drying techniques, preserving corn, berries, squash, chokecherries, and meat to survive cold seasons. They even made pemmican, a mix of dried meat, fat, and fruit, as a portable high energy food that inspired recipes still used today.

Modern households can easily dry food using simple appliances. Countertop dehydrators and home freeze dryers allow year-round preservation. Fruits like apples, cherries, and grapes and vegetables such as carrots, corn, potatoes, squash, and tomatoes all dry well. When properly dried and stored in moisture proof containers like glass jars, these foods stay fresh for several months.

Homemade fruit leathers, jerky, and trail mixes make healthy snacks for school lunches, hikes, and busy days. Drying also prevents food waste by using slightly overripe or leftover produce.

For best results, choose a dehydrator with a thermostat offering a temperature range of 85 to 160 degrees Fahrenheit and a two-speed fan for even airflow. Avoid ovens that heat too quickly, as they can form a hard outer “case” and trap moisture inside.

This autumn, try drying apple slices or making fruit leather from applesauce. Drying food connects us to ancient traditions while creating convenient, healthy snacks that highlight the harvest’s natural flavors.
