Healthy Snacks for School

School days are long for growing children with many kids having just enough time to hastily scarf down some cereal before running off to the bus. Lunch time can be similarly rushed because of the school’s need to get every student through the line. The result is often inadequate care for a student’s nutritional needs, making healthy snacks a must-have item to help children through the day.

Nutritional Considerations for Healthy Snacks

The body primarily uses carbohydrates, proteins, and fats for energy. The digestive system breaks these macronutrients into their component parts, making them a readily available energy source for a variety of tissues.

In general, carbohydrates are the most readily available sources of energy. Simple carbohydrates, which have a less complex molecular structure, lead to a rapid increase in blood sugar. Although major swings in blood sugar are not desirable, a modest increase in blood sugar levels can prevent the dips that trigger cravings, irritability, and mental fogginess (Holloway, n.d.). Complex carbohydrates, which take longer for the body to break down, then keep your child’s energy levels up for a longer period of time.

Healthy Snacks Enhance Concentration and Studying

Packing healthy snacks for school not only staves off hunger pangs but may also improve concentration and academic performance. In fact, snacks are particularly important in the mid-morning and mid-afternoon. Blood sugar levels typically spike at breakfast and again at lunch. However, they tend to be lower between these meals. This causes students to feel tired, irritable, and mentally unfocused. Eating a healthy snack causes blood sugar levels to stabilize (Massachusetts Institute of Technology, 2014).

Healthy snacking while at school results in significant changes in cognitive performance. A 2007 study found that school-aged children of low socioeconomic status who ate a mid-morning snack experienced improved memory performance during the day. Children of similar standing who did not snack experienced a mid-morning slump in which their memory and attention waned (Muthayya et al., 2007).

The best school snack is one that contains some carbohydrates and some protein, as protein can help quell cravings. For example, slices of cheese and a few crackers keep blood sugar levels stable while promoting satiety between meals. Eating a piece of fruit is another good way add carbohydrates to your diet to provide an energy boost in the mid-afternoon.

Practical Considerations When Packing Healthy Snacks for School

Many schools have policies about children snacking during class. Elementary school children may receive small snacks or a milk break during the day. For older children, parents can pack a non-perishable snack that would survive a few hours in a locker or backpack. Pre-made snack mixes are perfect for this purpose.

For instance, a small baggie of trail mix with nuts is a good way to provide much-needed protein to prevent hunger cravings. Because a fresh, juicy piece of fruit may be messy to eat at school, opt for dried fruit or fruit leathers instead. Packing a variety of non-perishable snacks at the beginning of the week is a helpful way to ensure your child has enough sustenance to get them through each day.
