Dehydrators are a fantastic way to eat healthier and lose weight, all while enjoying delicious preservative-free organic foods. Nesco is the best brand for regular home use. The difference in models and price more or less comes down to power. The 1000 watt model I own is capable of drying up to 30 trays at once, but most people will never need that kind of capability.
The (gold) 600 watt model not only has a good deal of power (expandable to 12 trays), it is capable of varying temperature with a built-in thermostat. This is important if you want to dry a range of things (e.g. meats, vegetables, herbs, etc). Temperature control is especially important for vegetables. The high vitamin content of vegetables break down above certain temperatures, losing nutritional value. This is another reason why dehydrating is such a healthy option. Having healthy, easy snacks nearby is so important to weight loss. When your body tells you it’s hungry, you’re going to eat something. Eat well. Snack well.
Combine this with a slicer for some easy making of jerky. Or consider a mandolin for basic slicing of vegetables. Also, if you need more trays, they run about $15 for 2. Which ones you’ll need depend on what model you buy. Here’s the trays for the gold model.
