Energizing Lunches

Protein is a meaty topic right now—what’s the best source, how much we need, and when to eat it. Researchers have found it’s more effective to eat protein at every meal versus one big serving at dinner. This ensures our muscles are constantly supplied with the amino acids needed for growth and repair.

Portioning protein throughout the day may also prevent the risk of having excess protein oxidize and turn into glucose or fat. At least 15 percent of our daily calories should come from protein. Add protein to your lunch routine and choose lean meats or fish, legumes, dairy, and nuts.

Carbohydrate ranking

From 45 to 65 percent of our daily calories should come from carbohydrates. Carbs are the body’s main source of energy. Once digestion occurs, all carbs end up as glucose (sugar) that’s released into the bloodstream. The key is to choose complex carbs that break down slowly—and that’s where the glycemic index (GI) comes in. It’s a numerical system that measures how fast a carbohydrate-containing food raises blood glucose, and then ranks it as either high or low.

High GI foods are digested quickly and rapidly raise blood sugar levels. Most processed foods fall into this ranking. However, some high GI foods do hold great nutritional benefits, such as ripe fruit, cereals, and whole wheat bread. Medium and low GI foods digest slowly and are often rich in fibre, vitamins, and minerals.

Foods such as whole grains, certain fruits, nuts, and most vegetables take longer to digest, which helps prevent insulin spikes and keeps blood sugar levels in check. Regardless of whether a food falls in the high or low GI category, the goal is to eat a varied and combined diet based on whole foods in proper portion sizes.
