Starch-Rich Foods: Comprehensive List by Category

Starch is a polysaccharide (glucose polymer) serving as plants' primary energy storage. Dietary starch provides sustained glucose release.

Grains & Cereals (Staple Starch Sources)

• Rice (white, brown, wild, black, red)
• Wheat (whole, durum, spelt, farro, bulgur, couscous, semolina)
• Corn (maize, polenta, grits, cornmeal, popcorn)
• Oats (rolled, steel-cut, groats)
• Barley (pearled, hulled)
• Rye
• Quinoa (pseudocereal, high protein)
• Sorghum, Millet, Teff
• Buckwheat (pseudocereal)
• Amaranth (pseudocereal)

Legumes (Pulses) — Starch + Protein + Fiber

• Beans: Black, kidney, pinto, navy, cannellini, lima, fava, adzuki, mung.
• Lentils: Brown, green, red, French (Puy), black beluga.
• Chickpeas (garbanzo).
• Peas: Split, whole, black-eyed.
• Peanuts (legume, high fat).
• Soybeans, edamame, tempeh, tofu.

Starchy Vegetables (Tubers, Roots, Corms, Winter Squash)

• Potatoes (white, red, yellow, purple, fingerling)
• Sweet potatoes / yams (distinct botanically)
• Cassava (yuca, manioc) / tapioca
• Taro, malanga, yautía
• Plantains (cooking banana)
• Jerusalem artichoke (sunchoke — inulin, not starch)
• Winter squash: Butternut, acorn, kabocha, delicata, spaghetti, pumpkin.
• Parsnips, turnips, rutabaga (moderate starch).

Fruits (Higher Starch When Unripe / Specific Types)

• Bananas (green → high resistant starch; ripe → sugar)
• Plantains (cooked as starch)
• Breadfruit, jackfruit (unripe)
• Dates, figs, persimmons (moderate)
• Most fruits: Low starch, high fructose/glucose/sucrose.

Isolated Starches & Derivatives

• Cornstarch, potato starch, tapioca starch, arrowroot, wheat starch, rice starch.
• Maltodextrin, modified food starch (thickeners, processed foods).

Resistant Starch (Fermentable Fiber)

• RS1: Physically inaccessible (whole grains, seeds).
• RS2: Raw granules (green banana, raw potato, high-amylose corn).
• RS3: Retrograded (cooked & cooled potato, rice, pasta).
• RS4: Chemically modified.
• Benefits: Feeds colonic microbiota → SCFAs (butyrate), improves insulin sensitivity, satiety.

Balance starch intake with fiber, protein, fat; choose whole/minimally processed sources for metabolic health.
