10 Potential Benefits Of Pecans For Skin, Hair, And Health

If you want to start a sodium-free diet, pecans are an excellent addition. The benefits of pecans can be attributed to their high protein content, antioxidants, vitamins, and minerals. This buttery-flavored nut is native to America and has anti-cancer and anti-inflammatory properties that help treat many ailments. Intake of pecans can help reduce the risk of cardiovascular disease, lower blood glucose levels, improve digestive health, and boost brain health.

Trivia

Pecans were first cultivated by Native Americans. The name “pecan” originated from an Algonquian word that means a nut that needs a stone to crack.

This article explores the potential health benefits of pecans, their nutritional breakdown, and any adverse effects. Take a look.

10 Potential Health Benefits Of Pecans

1. May Reduce Risk Of Heart Disease

As per studies, increased intake of nuts lowers the risk of heart disease. Tree nuts like pecans can lower the levels of disease-causing low-density lipoprotein (LDL) cholesterol and triglycerides (1), (2). LDL or bad cholesterol can clog arteries and cause heart attacks and cardiovascular disease. A study conducted by the New Mexico State University found that people who ate 68 grams of pecans (around 38 pecans) each day had lower levels of LDL cholesterol than those in the control group who didn’t eat nuts. However, due to their high calorie count it would be advisable to stick to portion sizes of around max 16 pecans per day) (https://pubmed.ncbi.nlm.nih.gov/10719404/). Pecans are rich in unsaturated fatty acids that have a positive effect on lowering cholesterol (4), (5).

A pecan-rich diet can improve cardiometabolic risk factors, thanks to the presence of oleic acid and phenolic antioxidants (6). Pecans are replete with bioactive components, such as gamma-tocopherol, which can prevent chronic inflammation of the arteries (7). The flavonoids in pecans possess antioxidant properties and may lower blood cholesterol levels (8).

2. May Lower Blood Sugar Levels

Pecans are rich in dietary fiber that helps regulate blood sugar levels (6). One cup of these edible tree nuts contains 10.5 grams of total dietary fiber (9). In general, dietary fiber decreases the absorption of macronutrients in the intestine and delays gastric emptying. This results in lower blood glucose levels (10).

A study conducted by the University of Toronto on people with diabetes concluded that adding nuts to your daily diet helps improve blood glucose levels (11).

3. May Promote Brain Function

Pecans are high in gamma-tocopherol, a form of vitamin E (6). Studies state that individuals who consume vitamin E (dietary antioxidant) can lower their risk of dementia (12). This vitamin can fight against oxidative stress (or free radical damage) that may otherwise damage brain cells (13).

Pecans are also an excellent source of ellagic acid. This polyphenol can help prevent age-related cognitive decline (14). A study conducted on 150 middle-aged males found that ellagic acid has the potential to improve cognition (15).

The monounsaturated fatty acids in pecans also help reduce cognitive decline and improve brain functioning (16). Long-term intake of nuts was linked with improved cognitive behavior in older women (17). Another study conducted by the University of South Australia on 4822 adults aged 55 and over showed that people who consume 10 grams of nuts per day were 40% less likely to have poor cognitive function (18).

4. May Help Fight Inflammation

The phenolic compounds (such as tannins) in pecans can suppress chronic inflammation-causing genes and reduce inflammation (6). Pecans are also a rich source of magnesium that may help fight inflammation too. It may reduce inflammation in the arterial walls and reduce the risk of cardiovascular disease, arthritis, and Alzheimer’s. However, more studies are needed to further understand this mechanism of action in pecans.

5. May Improve Digestion

Pecans are rich in polyphenols such as ellagitannins (ETs) that can function as prebiotics (promote the growth of beneficial intestinal microorganisms). Studies suggest that ETs increase the growth of two common gut bacteria like Bifidobacterium and Lactobacillus (19). Also, pecans are loaded with dietary fiber that helps promote digestive health by regulating bowel movements (20). These tree nuts can reduce the risk of hemorrhoids and gastrointestinal problems and prevent constipation (21). However, more human studies are needed to prove these claims.

6. Are Rich In Antioxidants

Pecans have antioxidant properties, thanks to their bioactive compounds like ellagic acid (22). Oxidative damage has been linked to heart disease, Alzheimer’s, and cancer – and pecans may help reduce the risk. As per one study conducted by the Loma Linda University, USA, the antioxidant capacity of pecans can reduce LDL oxidation in humans (7). The increase in gamma-tocopherol levels with a pecan-rich diet reduces the risk of coronary heart disease (23).

7. May Help With Weight Loss

Pecans are rich in dietary fiber that has the ability to enhance satiety (24), (25). Intake of fiber regulates appetite, increases metabolism, and decreases your urge to eat more. This, in turn, may help with weight loss. The nuts are also rich sources of niacin, vitamin B6, riboflavin, thiamin, pantothenic acid, and folate that help promote metabolism too (26).

8. May Reduce The Risk Of Certain Cancers

Pecan kernel extracts are said to possess anti-proliferative, antioxidant, and cell-protective properties (27). The ellagic acid in pecans has anti-carcinogenic effects that can inhibit rapid proliferation of cancer cells (28). Also, the dietary fiber in pecans may help reduce the risk of colon cancer, and the oleic acid can help reduce the risk of breast cancer (29), (30), (31).

9. May Improve Skin Health

Pecans contain numerous antioxidants, including vitamins A and E, which fight free radicals that otherwise cause premature skin aging. Vitamin A is also great for healing the skin and reducing breakouts. The fiber in pecans is thought to flush out the body’s toxins and promote skin health (32).

10. May Prevent Hair Loss

Pecans are rich in amino acids that promote blood circulation to the hair roots. These tree nuts also are a rich source of iron that may help fight hair loss (33).

Note: A higher daily intake of plant-based sources of iron (non heme) is needed in comparison to animal-based iron sources (heme iron) due to their lower absorption capacity by the body.

Pecans contain a wide variety of vitamins and minerals. Read on to discover their nutrition profile.

Nutrition Profile Of Pecans

Pecans have a rich nutrient profile, and they contain 19 vitamins and minerals. They are packed with fiber, magnesium, copper, zinc, and vitamin B1. As per the U.S. Department Of Agriculture, 100 grams of pecans contain the following nutrients (9):

• Calories: 691 kcal
• Protein: 17 g
• Carbohydrates: 9 g
• Fiber: 9.6 g
• Iron: 2.53 g
• Magnesium: 121 mg
• Zinc: 4.53 mg
• Copper: 1.2 mg
• Thiamin: 0.66 mg
• Riboflavin: 0.13 mg
• Niacin: 17 mg     
• Pantothenic acid: 0.863 mg
• Vitamin B-6: 0.21 mg

Minerals like copper and zinc have many health benefits and help boost immune health and brain function as well as skin health, thyroid, and metabolism (34), (35).
