Low-calorie, high-water vegetable that contributes volume and micronutrients to meals without adding significant caloric load; supports satiety on a calorie-appropriate longevity diet.. PMID 30263869: High vegetable consumption (≥5 servings/day including squash varieties) is associated with a 26% reduction in all-cause mortality; mechanistically linked to antioxidant phytochemicals, fiber, and potassium. (PubMed) PMID 29099553: Cucurbit vegetables including zucchini contain cucurbitacins and carotenoids (lutein, zeaxanthin) with demonstrated anti-inflammatory and anti-proliferative properties in vitro, consistent with longevity-promoting dietary patterns.

Key Nutrients

Nutrient	Per 100g	Notes
Potassium	~262 mg per 100 g raw	Supports blood pressure regulation and cardiovascular health; retained well in steaming vs boiling.
Vitamin C	~18 mg per 100 g raw (~20% DV)	Water-soluble; light steaming or sautéing preserves most vitamin C; boiling can reduce by 30–50%.
Folate	~24 mcg per 100 g raw (~6% DV)	Contributes to daily folate intake; important for DNA methylation and cell division.
Lutein + Zeaxanthin	~2.1 mg per 100 g	Fat-soluble carotenoids that protect the macula and support brain health; bioavailability enhanced by cooking with olive oil.
