Fats

The majority of the macronutrient in hickory and pecan nuts are composed of fats. Pecan nuts contain higher amounts of fats than hickory.

We can say that 72% of pecan is fat, and 64% of hickory is fat.

Since fats are the main component, it is important to mention their distribution in detail.

Although pecan contains more “total fat” than hickory, it contains less saturated fat and equal polyunsaturated fats. Among the polyunsaturated fats are omega-3 fats and omega-6 fats.

The fats are mostly unsaturated type distributed among polyunsaturated fats and monounsaturated fats.

Minerals

Both nuts are highly rich and diverse in their mineral profiles. Pecan is richer in copper, zinc, and iron. All these values satisfy the RDV of each respectively. In addition to that, the amount of phosphorus also satisfies the RDV. However, hickory contains higher amounts of phosphorus. On the other hand, hickory is richer in phosphorus and magnesium, and they both satisfy the RDV of each. In addition to that, copper and zinc amounts in hickory, although less than pecan, also satisfy the RDV of each.

Overall Health

Nuts in general, including hickory and pecans, have long been regarded to contribute to weight gain. On the other hand, science has determined a false assumption based on its research. They are high in calories due to their high monounsaturated and polyunsaturated fats. They are abundant in vitamins and minerals and healthy fats and help with digestion and metabolism. (1)

Cardiovascular Health

Section reviewed by cardiologist Astghik Grigoryan

Pecans are known for their high content of monounsaturated fats, particularly oleic acid, which is heart-healthy. They also contain antioxidants like vitamin E and phenolic compounds, which may help reduce inflammation and oxidative stress, both of which are linked to atherosclerosis (2, 3).

Hickory nuts, on the other hand, also contain healthy fats and some antioxidants, although their specific nutrient composition may vary slightly from pecans. They're also a good source of fiber, which can help lower cholesterol levels and improve heart health (4).

In general, including a variety of nuts in your diet, including both pecans and hickory nuts, can be beneficial for heart health. They can be part of a balanced diet that includes plenty of fruits, vegetables, whole grains, and lean proteins, all of which contribute to overall cardiovascular health. However, it's essential to consume them in moderation, as they are calorie-dense foods.

Diabetes

Pecan contains anti-diabetic flavonoids and phenolic substances that reduce total blood glucose levels and provide glycemic control. In addition to this capability, it has anti-oxidant properties. (5)

In addition, most nuts, including pecan and hickory, have characteristics that reduce metabolic syndrome, including obesity, hypertension, and diabetes. Reducing the risks of developing metabolic syndrome reduces the overall mortality rate. (6)

Cancer

On breast cancer cell lines, pecan extract has exhibited anticarcinogenic properties. (7)

Gallic acid present in hickory nuts has protective effects against ovarian cancer. (8)

Digestion

Section reviewed by gastroenterologist Arpi Gasparyan

Since they are both fiber-rich, they may alter the gut microbiome and increase Bifidobacterium and Lactobacillus levels, considered “good” bacteria; dietary fiber may also alleviate chronic constipation symptoms. 

According to several guidelines, eating fiber-rich foods may beneficially affect diverticular disease. (9) (10) (11)
