83 Calories, 4g Fiber, 38mcg Folate — The Aril-Only Nutrition Most Databases Get Wrong
Pomegranate arils (the edible seeds with their juice sacs, FDC 169134) deliver 83 calories per 100g with 1.67g protein, 1.17g fat, and 18.7g total carbohydrates including 13.67g sugars and 4g fiber (14% DV). Half a cup of arils (~87g) — a typical topping portion — has about 72 calories [1].
What many nutrition databases label as 'pomegranate' includes varying amounts of pith and membrane. The USDA entry (FDC 169134) is specifically for the edible portion — arils only. This matters because the pith contains concentrated tannins and different nutrients but is not typically consumed. Each aril consists of a translucent juice sac (the sweet part) surrounding a small white seed (the crunchy center) [1][2].
Folate at 38mcg per 100g (10% DV) is noteworthy — higher than most fruits and comparable to oranges (30mcg). A full cup of arils (~174g) delivers 66mcg folate (17% DV). Combined with 10.2mg vitamin C (11% DV) and 16.4mcg vitamin K (14% DV), pomegranate arils provide a broader vitamin profile than their common reputation as 'just an antioxidant food' [1].
Punicalagin: The Ellagitannin That Exists Almost Nowhere Else in the Human Diet
Pomegranate's most researched compound is punicalagin — a large ellagitannin molecule (MW ~1,084 Da) that is essentially unique to pomegranate among commonly consumed foods. Research has measured punicalagin at approximately 20-120mg per 100ml of pomegranate juice, depending on variety and processing. The concentration is highest in the peel and membrane, with arils containing lower but significant amounts [2][3].
Punicalagin is not measured in USDA nutrient panels — it falls outside the standard 25-nutrient analysis. Research tracks it as a polyphenol of interest because of its size and structure: it's one of the largest molecular-weight polyphenols in the human diet and is hydrolyzed to ellagic acid during digestion [2][3].
When eating arils, you consume punicalagin from both the juice sac (moderate concentration) and the seed (which contains some tannin compounds). Chewing the seeds releases more of these compounds than swallowing them whole. For nutrition journaling, note that pomegranate's bioactive compound profile is dominated by ellagitannins — a different category from the anthocyanins in berries or the flavonoids in citrus [2][3].
The Seed Inside the Aril: Punicic Acid and a Rare Fatty Acid Profile
Each pomegranate aril contains a small, white seed that accounts for about 12-20% of the aril's weight. These seeds contain pomegranate seed oil rich in punicic acid — a conjugated linolenic acid (18:3) that comprises approximately 65-80% of the seed oil's fatty acids. Punicic acid is extremely rare in the human diet, found almost exclusively in pomegranate seeds [2][3].
The total fat in arils is 1.17g per 100g — modest, but this small amount contains a unique fatty acid not found in virtually any other food. The seed oil also contains linoleic acid (~7%), oleic acid (~6%), and palmitic acid (~4%). You consume these fatty acids when you chew and eat the seeds rather than spitting them out [1][2].
Research has examined punicic acid's properties in laboratory and animal models, documenting it as a conjugated fatty acid with structural similarities to conjugated linoleic acid (CLA) — but derived from linolenic rather than linoleic acid. For food journaling, the practical note is that pomegranate seeds are one of the only dietary sources of this specific fatty acid [2][3].
½ Cup of Arils vs. 1 Cup of Blueberries: Comparing Two 'Superfood' Snack Portions
Half a cup of pomegranate arils (~87g) delivers: 72 calories, 1.46g protein, 16.2g carbs (11.9g sugar, 3.5g fiber), 8.9mg vitamin C (10% DV), 205mg potassium (4% DV), 33mcg folate (8% DV). One cup of blueberries (~148g) delivers: 84 calories, 1.1g protein, 21.4g carbs (14.7g sugar, 3.6g fiber), 14.4mg vitamin C (16% DV), 114mg potassium (2% DV), 9mcg folate (2% DV) [1].
Pomegranate arils win on potassium (80% higher per typical serving), folate (3.7x), and vitamin K (14.3mcg vs 28.6mcg per serving). Blueberries win on vitamin C (62% higher per serving) and provide anthocyanins rather than ellagitannins — a completely different class of polyphenol compounds [1].
The fiber content is nearly identical per serving (3.5g vs 3.6g), and calorie counts are close (72 vs 84). For a nutrition journal comparison, these are genuinely equivalent-tier snacks with different micronutrient strengths: pomegranate for folate and potassium, blueberries for vitamin C and manganese [1].

Practical Tips for Pomegranate Seeds
- 1
½ cup of pomegranate arils (~87g) delivers 72 calories, 3.5g fiber, and 33mcg folate (8% DV) — a nutrient-dense topping for yogurt, oatmeal, or salads. Seeds from one medium pomegranate yield about 1 cup (~174g) [1].
- 2
Pomegranate contains punicalagin — an ellagitannin found almost nowhere else in the human diet. It's concentrated in the peel and membrane but is also present in arils. Research tracks it separately from standard nutrients [2][3].
- 3
The small white seed inside each aril contains punicic acid — a rare conjugated fatty acid comprising 65-80% of pomegranate seed oil. Chewing the seeds releases these compounds; swallowing whole retains less [2][3].
- 4
Folate at 38mcg per 100g is among the highest of any fruit — higher than blueberries (6mcg), grapes (2mcg), and comparable to oranges (30mcg). A full cup of arils delivers 66mcg (17% DV) [1].
- 5
Vitamin K at 16.4mcg per 100g (14% DV) adds to the fat-soluble vitamin profile. A cup of arils provides 29mcg (24% DV) — significant for a fruit and relevant for vitamin K tracking [1].
