You probably know the mid-afternoon dip when you reach for whatever is nearest. For a lot of people, that is a cookie or a bag of chips. A small handful of nuts can slot into the same moment without much fuss.
Eating about one ounce of almonds a day, roughly 23 nuts, lowers LDL cholesterol (the so-called "bad" cholesterol) by a small but consistent amount.
The pattern has turned up across dozens of randomized trials, and the American Heart Association lists almonds among the nuts tied to a healthier heart.
The largest recent look came from a review in Nutrients in August 2025. It pooled 36 trials covering 2,485 adults and found that daily almonds dropped LDL cholesterol and total cholesterol. HDL cholesterol (the "good" kind) was unchanged.

Translated out of research units, the LDL drop sits in the single-digit percent range, with a similar effect on total cholesterol. ApoB, another blood marker tied to heart risk, also fell.
What a daily handful seems to change
The core finding has held up for a long time. An earlier meta-analysis in the Journal of Nutritional Science from 2016 pooled 18 trials. It found a modest drop in LDL cholesterol, a drop in total cholesterol and a drop in triglycerides, while HDL stayed roughly flat.
A 2024 review in Nutrients went a step further. It reported that daily almonds appeared to shift HDL toward larger, more useful particles.
The same review also linked the habit to a drop in diastolic blood pressure, the lower number on a reading. That echoes earlier work on almonds and blood pressure.

None of this is a cure for high cholesterol, and the trials were not testing almonds against statins. They were testing a food swap, and the swap shows up on blood tests in a small, steady way.
How much and for whom
The 2025 meta-analysis flagged two things that make the effect bigger. People whose cholesterol started high benefited more than those with normal numbers. The response also grew when the daily dose reached about 45 grams, roughly a handful and a half.
That does not make the standard one-ounce portion pointless. It is the serving on US nutrition labels. One ounce delivers about 6 grams of protein, 4 grams of fiber, 13 grams of unsaturated fat and 160 calories.
The American Heart Association suggests about four servings of unsalted nuts a week, with raw or dry-roasted nuts chosen over varieties fried in oil. The group lists almonds among the nuts most tied to heart health, alongside walnuts, hazelnuts and pecans.

Anyone with concerns about their cholesterol or who is on heart medication should talk to a doctor before changing their diet in a big way.
The gain shows up when the almonds replace a less healthy snack, not when they get piled on top of what you already eat.
