Snack foods are foods eaten between regular meals, ranging from chips and pretzels to fruit and yogurt, ideally offering nutrients rather than just calories.
We’ve all grabbed a bag of chips or an apple between lunch and dinner. Snack foods fill that gap. But the definition stretches further than the vending machine aisle. Food regulators, nutritionists, and school lunch programs each draw the line differently, and knowing where those lines sit helps you make better choices for yourself and your kids.
What Counts As A Snack Food?
The most practical definition: snack foods are edible items eaten between main meals. In U.S. guidance, the category commonly includes chips, pretzels, popcorn, crackers, fruit snacks, dried fruit, snack mixes, cookies, cakes, candy, ice cream, and similar items. The FDA’s product category list specifically names “snacks” with examples like chips, pretzels, popcorn, extruded snacks, fruit-based snacks, and grain-based snack mixes.
Some definitions also treat nuts, granola bars, and yogurt as snacks when eaten outside mealtimes. The unifying thread isn’t the ingredient—it’s when and how you eat it.
What The USDA Says
The USDA takes a broader view in some programs and a narrower one in others. Their SNAP accessory foods list treats many snack items as “accessory foods” that can be purchased with benefits. For school food sales, the USDA’s Smart Snacks rules—effective July 1, 2014, codified at 7 CFR 210.11—set specific nutrient standards that apply to snacks sold in schools. Those rules distinguish between single foods, combination foods, and packaged items that would each qualify individually.
Are Snack Foods Healthy?
It depends entirely on what you pick. The U.S. guidance is consistent: choose whole, minimally processed foods, and pair carbohydrates with protein or healthy fat for snacks that keep you satisfied. A handful of almonds with an apple beats a bag of gummy bears on every metric that matters.
Health-oriented guidance also recommends limiting snacks high in saturated fat, added sugar, and sodium, while favoring nutrient-dense options. Treating snacks as “empty calories” is discouraged—snacks can deliver real nutrition when chosen deliberately.
| Smart Snack Choice | Why It Works | Better Than |
|---|---|---|
| Apple slices + peanut butter | Fiber plus protein and healthy fat for lasting fullness | Apple-flavored fruit snacks with added sugar |
| Greek yogurt + berries | Protein, calcium, and antioxidants in one cup | Yogurt-covered pretzels with minimal real yogurt |
| Popcorn (air-popped) | Whole grain with fiber, low in calories when unbuttered | Butter-drenched movie theater popcorn |
| Carrot sticks + hummus | Vegetable serving plus plant-based protein | Potato chips with ranch dip |
| Trail mix (portion-controlled) | Nuts, seeds, and dried fruit in one satisfying handful | Snack mix with mostly pretzels and candy pieces |
Portion size matters just as much as the food itself. Common health guidance suggests snack portions around 150–250 calories, with many examples landing near 150–200.
Smart Snacks Rules In Schools
The USDA’s Smart Snacks standards, in place since July 2014, govern what schools can sell to students during the school day. These rules apply to vending machines, school stores, and à la carte lunch lines. For a snack to qualify, it must meet limits on calories, sodium, sugar, and fat while providing one of several beneficial nutrient groups—whole grains, fruit, vegetables, dairy, or protein.
A “combination food” contains two or more foods from two or more food groups. When combined, these foods lose their individual exemptions and must meet the snack nutrient standards as a whole. However, items that are individually exempt can be packaged together without extra ingredients and keep those exemptions—though they still must meet calorie and sodium limits. So a bag combining separately compliant pretzels and nuts can pass, but a mix that adds a new ingredient must be evaluated as a new product.
What Is A Reimbursable Snack Under CACFP?
The Child and Adult Care Food Program (CACFP) has its own snack rules. For a reimbursable snack, schools and childcare centers must serve two of the five required components—milk, fruit, vegetable, grain, or meat/meat alternative. Using only milk and juice does not satisfy the requirement, no matter how healthy those two items seem. You need items from two different component categories to count.
How To Choose Better Snacks
The pattern is simple: aim for whole or minimally processed foods, pair a carbohydrate with protein or healthy fat, and watch the portion. Nuts and cheese offer protein and fat. Fruit and whole-grain crackers offer the carbohydrate. Combine them and you get a snack that holds you until the next meal without the sugar crash.

Remember that a snack isn’t automatically good or bad because of its category. A handful of chips can fit a balanced diet; a “healthy” granola bar loaded with sugar can derail one. Read labels, watch portions, and let the nutrient content—not the marketing—make the call.
FAQs
Are snacks the same as junk food?
No. Snacks are simply foods eaten between meals. Junk food refers to items high in calories, sugar, salt, or fat with little nutritional value. Many snacks—fruit, nuts, yogurt, whole-grain crackers—are nutrient-dense and support a healthy diet. The category isn’t the problem; the specific product choice determines whether a snack helps or hurts.
How many snacks should you eat per day?
There’s no single universal number—it depends on your meal size, activity level, and hunger cues. Many people do well with one to two snacks daily, especially between breakfast and lunch or lunch and dinner. The better question is whether your snacks add nutrients you’re missing at meals rather than just extra calories from sugar and refined grains.
Can you lose weight while eating snacks?
Yes. The key is choosing snacks that fit within your daily calorie goal—typically 150–250 calories per snack. High-protein and high-fiber options like Greek yogurt, nuts, or vegetables with hummus keep you full longer, which can prevent overeating at your next meal. Snacking itself doesn’t cause weight gain; consistently exceeding your energy needs does.
