Calories and macros are only part of the story.
Most nutrition apps stop at calories, protein, carbs, and fat. But the compounds with the strongest links to long-term health — polyphenols — aren't tracked at all. Research suggests a daily intake of approximately 650 mg of total polyphenols is associated with reduced risk of heart disease, cognitive decline, and chronic inflammation. How close are you?
What Pl3nish Tracks
Flavonoids
The largest class — includes anthocyanins in berries, catechins in tea, and quercetin in onions. Linked to heart health, reduced inflammation, and cognitive function.
Found in: Blueberries, green tea, dark chocolate, red wine, citrus
Phenolic Acids
Found abundantly in coffee, whole grains, and fruits. Support antioxidant defense and may protect against UV damage and certain cancers.
Found in: Coffee, whole wheat, berries, artichokes, pears
Stilbenes
Resveratrol is the most famous. Produced by plants under stress. Associated with cardiovascular protection and longevity research.
Found in: Red wine, red grapes, peanuts, blueberries
Lignans
Plant compounds with estrogen-like activity. Metabolized by gut bacteria into protective compounds. Associated with reduced breast cancer risk.
Found in: Flaxseed, sesame seeds, broccoli, kale, strawberries
Other Polyphenols
Includes curcuminoids (turmeric), tyrosols (olive oil), and tannins. Diverse compounds with anti-inflammatory, antioxidant, and gut health benefits.
Found in: Turmeric, olive oil, dark chocolate, walnuts, cloves
Why Track Polyphenols?
Heart Health
Polyphenols improve blood vessel function, reduce oxidative stress on LDL cholesterol, and support healthy blood pressure. Studies show diets rich in polyphenols reduce cardiovascular risk by up to 30%.
Brain Function
Flavonoids cross the blood-brain barrier and have been shown to improve memory, attention, and processing speed. Regular intake may reduce age-related cognitive decline.
Gut Health
Polyphenols act as prebiotics — feeding beneficial gut bacteria that produce short-chain fatty acids. A healthy gut microbiome influences immunity, mood, and nutrient absorption.
Inflammation
Chronic low-grade inflammation drives most modern diseases. Polyphenols modulate inflammatory pathways, reducing CRP and other biomarkers associated with disease risk.
How Pl3nish Tracks Polyphenols
Log a meal
Search 18,000+ recipes or describe any food with Nutritionix.
We match ingredients
Each ingredient is matched to our polyphenol database built from Phenol-Explorer research data.
See your breakdown
Total polyphenols per serving, broken down by flavonoids, phenolic acids, stilbenes, and lignans.
Track your P3 Score
Your daily and weekly polyphenol intake is scored against the 650mg research target alongside macros and micros.
Why Other Apps Can't Do This
Polyphenol data isn't in USDA's standard nutrition database — it requires a separate research dataset (Phenol-Explorer) and custom ingredient matching. That's why no mainstream nutrition app tracks it.
Try our free Polyphenol Lookup tool
Search any food and see its polyphenol content per serving — with compound breakdown. No account needed.
The P3 Score
One score that captures the completeness of your nutrition across three dimensions:
