Who Can Benefit
-
Broad group: Busy adults and health-minded readers seeking a simple, heart-friendly snack that fits into daily life.
-
Medium group: People with overweight/obesity and prediabetes who want a tasty option that may help stabilize blood pressure patterns and support long-term vascular health.
-
Narrow, symptom-based group: Individuals especially concerned about blood pressure variability or nighttime blood pressure, seeking easy, everyday dietary tricks to smooth fluctuations.
What Research Shows
Almonds may help improve blood pressure stability in adults with overweight/obesity and prediabetes.
In a small, carefully designed study, 34 participants consumed 50 g of whole almonds daily for five months, with a switch to a control period and a washout in between. Arterial stiffness and most markers of inflammation or endothelial function did not change with almond intake. Systolic blood pressure fell by about 3–4 mmHg across 24 hours, during the day, and at night, and the variability of systolic blood pressure also improved at all time frames, including nighttime. The retinal microvasculature showed a tiny change (a 2 μm increase in central retinal venular caliber), while other microvascular measures and biomarkers stayed roughly the same. Taken together, almonds did not overhaul vascular stiffness or inflammatory markers, but they did modestly lower blood pressure and make it more stable—a potential win for heart health in this population.
Bottom line: adding almonds may support everyday blood pressure control, even if other vascular and inflammatory markers don’t shift dramatically.
How to Eat It
- Recommended Serving
- Use a daily serving similar to the study: about 50 g of almonds per day (roughly a generous handful). If 50 g feels too much at first, start with 20–30 g and work up to ~50 g as tolerated.
- Easy Ways to Eat
- Eat them as a midday snack on their own.
- Sprinkle chopped almonds on yogurt, oatmeal, or smoothie bowls.
- Toss into salads for extra crunch.
- Mix into homemade trail mixes with dried fruit or whole-grain cereal.
- Flavor Pairings
- Enjoy with citrusy foods (orange, lemon) and olive oil for a Mediterranean-inspired bite.
- Pair with yogurt or berries for a creamy–crunchy contrast.
- Combine with cinnamon or cacao for a warm, dessert-like option.
- Roast lightly with a touch of sea salt and garlic for a savory snack.
Takeaway
A daily handful of almonds can be a tasty, practical habit that modestly lowers and stabilizes blood pressure in people with overweight/obesity and prediabetes, without needing to overhaul vascular markers. If you’re looking for a simple swap or addition to your routine, starting with about 50 g of almonds per day could be a realistic first step toward steadier blood pressure and everyday wellness.
