Almonds (the seeds of the almond fruit) are supported by scientific evidence for their beneficial effects on cholesterol levels, specifically in lowering LDL ("bad" cholesterol) and maintaining or increasing HDL ("good" cholesterol). Multiple randomized controlled trials and meta-analyses have demonstrated that regular almond consumption can lead to moderate reductions in total and LDL cholesterol in individuals with normal or elevated cholesterol levels. The primary mechanisms are believed to involve almonds' high content of monounsaturated fats, fiber, phytosterols, and antioxidant compounds such as vitamin E. These components work synergistically to reduce cholesterol absorption and improve lipid profiles.

For example, a meta-analysis published in the journal Nutrition Reviews (2016) found that almond consumption significantly reduced total cholesterol and LDL cholesterol, with an average daily intake of 45 grams yielding the most consistent results. Another study in the American Journal of Clinical Nutrition (2015) echoed these findings, showing that almonds can replace less healthy snacks to improve cholesterol profiles. While most research focuses on using almonds to lower elevated cholesterol, the evidence for using almonds specifically to support or treat low cholesterol (hypocholesterolemia) is limited, as low cholesterol is less commonly a therapeutic target. Nonetheless, almonds are not associated with lowering cholesterol to unhealthy levels and are generally considered heart-healthy.

In summary, there is strong scientific evidence supporting the use of almonds to manage cholesterol, especially to lower elevated levels, though direct evidence for treating low cholesterol is minimal.
