Cooking on an outdoor grill, barbecue or smoker is a summertime tradition that supplements the laid-back feel of summer and gets us all outside to enjoy not only the warm weather, but delicious food too. Grilled food not only tastes better but also provides many health advantages.
Outdoor grilling and barbecuing have evolved from what might have seemed limited to hamburgers, steaks, sausages and hot dogs not too long ago to a time when nearly everything can be cooked outdoors over an open flame or in a smoker. Kitchen ovens and frying pans are no match for the flavors a grill embeds in meats and vegetables.

The chemical reaction that makes food tastes better when heated is known as the Maillard Reaction, named for French chemist Louis-Camille Maillard (1878-1936), who studied the browning effect on foods. Heat from a grill breaks down food proteins into amino acids, which react with sugars to create the browning effect.
The Maillard Reaction starts when you cook at temperatures around 300 to 500°F, browning and adding crispiness to the outside surface of food and creating the strong flavors we all love from grilled food. Heat from an open flame or from inside a smoker just makes food taste better, and not just meats. Vegetables erupt with flavors absent when braising and boiling.

The Maillard Reaction combines with the caramelization reaction which also occurs when cooking at high temperatures. Caramelization is the browning of sugar molecules, which produces a nutty and sweet flavor. Over-grilling and over caramelizing can lead to the blackened, burnt and charred mess we all try to avoid.

Grilled food not only tastes better, it also has nutritional benefits. Higher heat levels used in grilling cause more vitamins and minerals to react with the food, adding nutrients that aren’t available through other cooking methods like boiling or baking. Grilling also requires less or no added fat, such as oil or lard. This allows us to enjoy our delicious grilled foods knowing it’s healthier for us. Grilling may reduce risks for heart disease, some cancers, and type 2 diabetes.
