A small bag of peanuts, cashews or sunflower seeds are rich sources of heart-healthy fats and protein. Pick up a vegetable juice or some low-fat milk from the convenience store fridge for some additional vitamins.
Tip: You can find nuts and seeds in trail mixes, but be sure to look at the serving size before munching away on an entire bag. The addition of chocolate-covered nuts or candy can also inflate the number calories you’re taking in with one snack, so pick an option with just nuts and dried fruit.
