Choosing a balanced afternoon snack can help keep your heart healthy.

Heart-healthy snacks should contain a mix of protein, fiber and healthy fats.

What you eat in the afternoon can affect your heart and energy levels for the rest of the day. Many people eat sugary snacks or don’t eat at all. Both habits put stress on the body, destabilize blood sugar, and lead to poor metabolic health over time, which can harm heart health.
Choosing balanced snacks with heart-healthy ingredients like nuts, seeds, fiber and whole grains can help control cholesterol levels, support a healthy weight and keep you fuller longer, all of which are good for heart health. To share more of the best heart-healthy afternoon snacks, we dug into the science and spoke with cardiologists.
1. Unsalted nuts
Nuts, such as almonds and walnuts, are well-researched heart-healthy snacks. They contain unsaturated fats, fiber and plant compounds that help support healthy cholesterol levels and reduce inflammation.
Kunal Lal, MD, calls almonds “a delicious, crunchy snack that I often recommend,” noting that they are high in heart-healthy monounsaturated fat and provide fiber. He often tells patients that substituting almonds for potato chips can satisfy the urge to chew while supporting heart health.
This aligns with advice shared by Johanna Contreras, MD, who emphasizes choosing whole foods because choosing minimally processed snacks is important for heart health.
Walnuts offer similar benefits to almonds, including plant-based omega-3 fats, which can help reduce the risk of heart disease by promoting healthy cholesterol levels.
The ideal serving size of nuts is a small handful, or 1 ounce. 2 tablespoons of nut butter is also important. Choose varieties with no added salt or sugar. Try serving it with a handful of almonds and sliced pears, spreading nut butter on whole wheat crackers, or sprinkling chopped walnuts on yogurt.
2. Hummus with vegetables
Vegetables are often overlooked when it comes to snacking, but they are one of the most heart-healthy foods.
Contreras emphasized vegetables as a good choice, saying vegetables are ideal for snacking, such as celery or carrots with hummus. Pairing veggies with hummus adds a bit of plant-based protein and extra fiber, creating a more balanced snack.
Fiber also helps lower low-density lipoprotein (called “bad”) cholesterol, keeping you fuller for longer, making you less likely to overeat later in the day. At least 3 grams of fiber in snacks is a good goal. Try dipping baby carrots, cucumbers or sliced peppers into hummus or other legume dips.
3. Fruit
Fruits like berries provide fiber, minerals, and antioxidants that support blood vessel function and reduce oxidative stress—key factors in long-term heart health. Polyphenols may also help reduce the risk of type 2 diabetes.
Contreras said one snack she often recommends is berries and plain Greek yogurt. The benefits of blueberries, especially for heart health, are well documented. Their nutrients help keep blood vessels flexible, reduce inflammation, and support healthy blood pressure levels. Additionally, blueberries provide you with carbohydrates for energy and fiber to help you stay full.
Lal singled out mangoes, noting that they are rich in fiber, potassium and antioxidants such as vitamin C, nutrients that contribute to heart health. Antioxidants protect blood vessels from oxidative stress and inflammation, he added.
Buying frozen fruit is cost-effective and provides the same nutritional content. Make sure to pair fruit with protein or healthy fats to make your snack more satisfying and prevent blood sugar spikes. Try serving fruit with yogurt, a handful of nuts, or chia seed pudding.
4. Whole wheat toast or avocado crackers
Whole wheat bread and crackers make a smart afternoon snack base because they provide fiber and slowly digesting carbohydrates that help maintain stable energy levels.
When paired with avocado, this snack can provide extra cardio protection. “Avocados are rich in monounsaturated fat, dietary fiber and potassium,” says Lal. “Fiber helps lower cholesterol,” he explains. [while] The potassium in avocados helps regulate blood pressure. “
One of Lal’s helpful tips is to mash avocado on whole-wheat toast or turn guacamole into a vegetable spread. Whole-wheat crackers also contain B vitamins, which help your body convert food into usable energy, while fiber helps support ideal cholesterol levels and gut health. Cookies are convenient to take with you to work or on the go and can easily be paired with other snacks.
Be sure to check the label to make sure the cookies are low in sodium and have whole grains as the first ingredient. In addition to avocado, you can pair crackers or toast with nut butter or cheese.
What makes a heart-healthy afternoon snack?
To create a heart-healthy afternoon snack, two cardiologists offer some practical tips you can apply.
Combine fiber-rich carbohydrates with protein and healthy fats to stabilize blood sugar and support cholesterol balance.
Lal also advises patients to limit foods high in saturated fat, which directly increases total and LDL cholesterol. “Red meat, processed meat, sweet foods such as ice cream and baked goods, and full-fat dairy products should also be kept to a minimum,” he said.
Finally, plan ahead. Contreras encourages patients to pack snacks ahead of time to reduce the likelihood of grabbing convenience items that are loaded with sugar and empty calories.
You can use the following framework to create heart-healthy snacks:
-
Include at least one of the following:
Healthy fats: Nuts, seeds, avocados, olives -
fiber rich foods: Fruits, vegetables, whole grains, legumes or legumes
-
protein: Strain Greek yogurt, nuts, cheese, beans
-
Mix food groups as much as possible. Achieve at least two of the following goals:
protein -
Limit added sugars and excess sodium. Choose snacks:
Minimal added sugar -
Less than 20% of daily intake of sodium
Our expert opinion
An afternoon snack isn’t just about avoiding hunger, it’s a daily opportunity to actively support heart health.
The right foods can help stabilize blood sugar, provide nutrients associated with healthy cholesterol and blood pressure, and reduce the likelihood of overeating later in the day.
Over time, these small daily choices can add up to meaningful cardiovascular benefits. Focusing on a simple combination of fiber, healthy fats, and protein can turn that afternoon slump into a steady, heart-supporting routine.
