Acorns vs. Chestnut — Health Impact and Nutrition Comparison
Summary
Chesnut is richer in potassium, phosphorus, iron, and vitamins B1 and C. They are packed with ellagic and gallic acids, which provide positive health impacts. In comparison, acorns are higher in calories and carbs. They are richer in unsaturated fats, most B complex vitamins, copper, magnesium, and manganese.

Introduction
This article is a comparison between chestnuts and acorns. We will discuss general differences, nutritional content comparisons, and health impacts.
Are acorns and chestnuts the same? This is the most common question related to this topic. The answer is clear. No, they are not the same. Acorns are different from chestnuts; acorns come from the oak tree and are smaller with a lighter color, whereas chestnut comes from the chestnut tree and is larger and has a darker color.
When matured and roasted, chestnuts tend to have a sweeter taste and can be easily eaten. In contrast, acorns contain tannins which give acorns a bitter taste.
Now that we answered the main question about the difference between chestnuts and acorns, we can discuss their nutritional content differences and health impacts.
Nutritional content comparison
In this section, we will compare 100g of each nut.
Calories
Acorns contain nearly 2.7 times more calories compared to chestnuts. Acorns contain 387 calories per 100g, whereas chestnut contains 131 calories per 100g.
Carbs
Acorns contain a higher amount of carbs compared to chestnuts. Acorn contains nearly 40g of carbs, whereas chestnut contains 27g.
Proteins
Considerably, acorns are richer in proteins compared to chestnuts. Acorns contain 6g of protein compared to 2g in chestnuts.
Fats
Acorns are much higher in fats compared to chestnuts. Chestnut contains low amounts of fats, considerably negligible. However, acorns are high in fats, mostly in unsaturated forms.
Minerals
Chestnut is richer in potassium, phosphorus, and iron. In comparison, acorns are richer in manganese, magnesium, and copper.
They are packed with minerals; in the diagram below, we can visualize their difference.

Health impacts
In this section, we will focus on the differences each provides regarding their health impacts.
Antioxidative properties
Chestnuts are packed with gallic and ellagic acids, which have antioxidative, anti-inflammatory, and antineoplastic activities. In addition, ellagic acid has neuroprotective properties. (1) (2)
Although chestnuts are packed with vitamin C, however, during the boiling or roasting process, vitamin C properties are lost because ascorbic acid is heat labile. (3)
Metabolic and cardiovascular health
Because the potassium in chestnuts and acorns may decrease arterial blood pressure, eating these foods may reduce the risk of developing arterial hypertension (4).
Chestnuts and acorns have beneficial effects on lipid control. According to this rat study, rats fed chestnut pericarp had significantly lower plasma total cholesterol in comparison to the control group (5). Consuming chestnuts in moderation on a regular basis can help to lower bad cholesterol while increasing good cholesterol, which is important for people with coronary heart disease (6).
Chestnuts are high in vitamin B12, vitamin B6, and folates, all of which may aid in the prevention of various types of heart disease, such as heart attack and stroke (7).
Tannins and iron absorption
Acorns contain higher amounts of tannins compared to chestnuts. However, acorns and chestnuts contain tannins in uncooked forms. Castalgins form chelates with bioavailable iron that we consume and reduce their bioavailability. Thus it is essential not to eat acorns or chestnuts raw. (8)
Digestion
Acorn extracts have been shown to have beneficial effects on indigestion. One study concluded that after a few months of taking acorn extract, patients experienced improved digestion with reduced epigastric pain and fewer pain episodes. (9)
Allergy
Chestnuts and acorns are tree nuts that can have cross-reactivity in allergic reactions. It is essential to be cautious if you have tree nut allergies. (10)
