Healthiest Nuts: 16 Nutritious Nuts Ranked from Best to Worst
Nuts are excellent, nutritious additions to any diet, but what are the healthiest nuts to eat?
Before we get into our rankings of the healthiest nuts, it's useful to see what makes nuts healthy.
The Health Benefits of Nuts
Many epidemiological studies have shown that eating nuts is correlated with many markers of good health and lower rates of obesity and chronic diseases.
Replacing parts of your diet with nuts can have a positive effect on your health. As state by Harvard Health,
"An analysis of data from the Harvard-based Nurses' Health Study showed that having one serving of nuts a day is associated with a 30% lower risk of heart disease compared with having one serving of red meat a day."
And in the Blue Zones, where the population has a disproportionately high rate of active, healthy centenarians, nuts are a key part of their diets.
Why are Nuts Healthy?
The most nutritious nuts have a wide variety (and high density) of nutrients important for a balanced diet.
Things like vitamins, minerals, and other phytochemicals are found in nuts, sometimes in high amounts. This is important, because deficiencies in these micronutrients can lead to poor health.
The best nuts have a wide variety of these nutrients.
Nuts are Nutrient-Dense
The healthiest nuts also have a high density of these nutrients. What does this mean?
It's important to look at the nutrient density of foods, because ideally we should be consuming a moderate amount of calories.
If you consume more calories than you expend throughout the day, you'll gain weight. So, eating a reasonable amount of calories is an important first step in a healthy diet.
But within the calories you eat, you want to make sure these other essential nutrients are coming along for the ride!
This is also important for nutrients you might want to eat less of.
For example, sugar.
100 grams of blackberries have around 4.9 grams of sugar, whereas 10 grams of cashews have around 5.9 grams of sugar.
But the _density _of sugar in blackberries vs. cashews is very different.
100 grams of blackberries comes in at around 43 calories, while 100 grams of cashews is around 553 calories. That means, while a handful of cashews might satisfy your hunger for a while, you'll be reaching for more calories soon after your blackberry treat!
We do still recommend blackberries! See our similar ranking of the healthiest fruits
So on an equal-calorie comparison, blackberries have about 0.45 grams of sugar per calorie, while cashews have about 0.04 grams of sugar per calorie.
The story is looking very different.
The World Health Organization recommends that fewer than 10% of your calories come from sugar (ideally, less than 5%).
On a calorie-based comparison, cashews are _much less sugar-dense _than blackberries.
The Healthiest Nuts have a Heart Healthy Macronutrient Profile
Micronutrients are important for a well-balanced diet. But it's also good to keep your macronutrients in check, too.
Your intake of dietary fats, carbohydrates, and proteins are important to keep within recommended balanced ratios.
Also important is the composition of these macronutrients.
For example, the American Heart Association suggests that less than 10% of your calories come from saturated fats.
The most nutritious nuts in our ranking are low in saturated fats.
But fat is a critical and necessary component of your diet. Some fat is important.
And unsaturated fats, polyunsaturated fats in particular, show heart healthy properties.
Many of the health benefits of nuts derive from their quality fat content, having low saturated fats and high in linoleic acid and alpha-linolenic acid (two polyunsaturated fats).
Many nuts also have a decent concentration of protein, too. Almonds, pistachios, and cashews are a few high protein nuts.
The Best Nuts are Good Sources of Fiber
Fiber is a very important dietary component that we often don't get enough of in our diets.

Fiber is important for everything from heath health and gut health to weight-loss and insulin regulation.
The healthiest nuts are fiber-dense. A few particularly high on the list are gingko nuts and chestnuts.
The Most Nutritious Nuts are Rich with Phytochemicals and Antioxidants
Whole foods are advocated among nutritionists in large part due to their vast array of various nutrients packaged together in piece. The synergies from this often add up to a number greater than the sum of their parts.
For example, the high sugar content of fruits is much less of a health issue because their high fiber content helps regulate the insulin response.
And fat-soluble vitamins are better absorbed when consumed with some amount of dietary fat.
Another benefit along these lines are phytochemicals - a term that embodies the molecules present in plant-based foods that often serve a nutrition and biochemical purpose but are not as well characterized by nutrition science.
For example, anthocyanins are flavonoids widely distributed in fruits and vegetables that exhibit antioxidative, anti-inflammatory, and neuroprotective properties.
And others like flavanols and isoflavones similarly show evidence of protective health benefits.
Similarly, the most nutritious nuts also contain caratenoids like lutein, shown to provide positive benefits to eye health.
The Healthiest Nuts Have High Concentrations of Many Nutrients
To rank high our list of the healthiest nuts, it takes more than just a high density of one or two nutrients.
For example, chestnuts have nearly 5.5X the daily recommended intake (DRI) value on a per-calorie basis - far more than any of the other nuts.
But in our ranking, this doesn't provide over twice the nutrient value of gingko nuts with around 2.2X the DRI.
Why? You will just pee out most of the extra!
Consuming many of these nutrients in excess of quantities that should provide enough nutrition to thwart both clinical and sub-clinical deficiencies won't provide much added benefit.
Therefore, the healthiest nuts in our ranking have a high density of nutrients, but also a breadth of nutrients. They provide a more complete and well-balanced source of more nutrition than the others.
Taking all of this into consideration, the gingko nut ranks #1 on our list of the healthiest nuts!
Although less popular in the US, gingko nuts - nuts from the gingko biloba tree - are popular in Japan.
Gingko nuts are dense with many essential nutrients, they contain important phytochemicals, they are low calorie and dense with fiber, and they have a heart healthy fat profile.
