Research reviews and clinical trials have found that regular almond consumption may improve LDL cholesterol and other cardiovascular risk indicators when included as part of a balanced diet.

Regular almond consumption has been associated with improvements in several markers tied to cardiovascular health, including lower LDL cholesterol, reduced waist circumference and decreased inflammation, according to findings from multiple peer-reviewed studies and research reviews.
Almonds are the most widely consumed tree nut in the world and provide a concentrated source of unsaturated fats, fiber, vitamin E, magnesium, protein and other nutrients connected to heart health. Researchers have increasingly examined whether adding almonds to the diet can help improve blood lipid levels and other risk factors for cardiovascular disease.
A systematic review and meta-analysis published in the Journal of Nutritional Science examined 18 randomized controlled trials involving 837 participants. Each trial lasted at least four weeks and included almond consumption as part of the participants’ diets. The review found that almonds were associated with statistically significant reductions in total cholesterol and low-density lipoprotein cholesterol, or LDL, without harmful changes in high-density lipoprotein cholesterol, known as HDL, or triglycerides.
The size of the cholesterol changes varied across studies. Researchers said the differences may reflect participants’ starting cholesterol levels, their overall diets and the amount of almonds consumed.
A separate Oregon State University study published in June 2025 found additional benefits among adults with metabolic syndrome. In that trial, participants were assigned either a daily snack of 2 ounces of whole almonds or a calorie-matched control snack. After six weeks, the almond group had a 5% reduction in LDL cholesterol and a 7% decrease in apolipoprotein B, a marker associated with cardiovascular risk. Researchers also reported reductions in waist circumference and gut inflammation.
The Oregon State researchers said the findings add to evidence that almonds may be a practical dietary tool for people at elevated risk of heart disease. They also reported that participants adhered well to the almond snack plan and that no adverse effects were reported during the six-week study period.
Other research has reached similar conclusions. A review by Canadian researchers published in the Journal of Nutritional Science concluded that almonds can help support healthy blood lipid levels when incorporated into a balanced diet. The authors said those benefits should be considered alongside other heart-healthy habits, including regular physical activity and limiting processed foods high in sugar and unhealthy fats.
In another study cited in the book “The End of Heart Disease,” participants who consumed a diet using almonds as the primary fat source had total cholesterol levels 7% lower than those who consumed a diet rich in coconut fat.
Researchers have pointed to several possible reasons almonds may support heart health. Nuts contain mono- and polyunsaturated fats, plant sterols, antioxidants and fiber, all of which may contribute to lower cholesterol and reduced inflammation. A review in Nutrients highlighted those components as part of the reason nut consumption has been linked to lower cardiovascular disease risk.
Nutrition guidance also supports replacing saturated fats with unsaturated fats from foods such as nuts and fish. The book “Understanding Nutrition” notes that using unsaturated fats in place of saturated fats is a recommended dietary strategy for protecting cardiovascular health.
Still, researchers and experts have noted several limits in the evidence. Some almond studies, including the meta-analysis and the Oregon State trial, were funded in part by the Almond Board of California. Other limitations include incomplete accounting for participants’ total food intake in some studies, making it difficult to isolate the effect of almonds from the rest of the diet.
Experts also caution that almonds should not be viewed as a standalone treatment for high cholesterol. Instead, they are best understood as one part of a broader dietary pattern that includes vegetables, fruits, whole grains, legumes, healthy fats and limited intake of highly processed foods.
The cumulative research suggests almonds can be a useful part of a heart-healthy diet. For people seeking dietary ways to manage cholesterol, almonds offer a portable source of healthy fats, fiber, protein and essential nutrients. Some analyses have described almonds as a natural dietary option for people interested in reducing cholesterol, though researchers said medication decisions should be made with a health care professional.
Current dietary recommendations generally support eating nuts as part of a balanced diet for cardiovascular health. Researchers said additional long-term studies are needed to determine the sustained effects of almond consumption and to identify optimal serving sizes.
A practical daily serving is often described as a handful of almonds, about 1 to 1.5 ounces, which can be eaten as a snack or added to meals.
