Enhancing Nutrients and Phytonutrients in Ohio Grown Foods: A Focus on Optimal Health

Cooking and preserving methods significantly influence the nutrient and phytonutrient levels in fruits and vegetables, with effects varying by method and nutrient type.

Boiling and Nutrient Loss

Boiling often causes substantial loss of water-soluble nutrients such as vitamin C and some antioxidants, as these leach into the cooking water. However, consuming the cooking liquid can help mitigate this loss.

Steaming for Better Nutrient Retention

Steaming generally preserves more nutrients and phytonutrients than boiling because it minimizes contact with water and reduces nutrient leaching, maintaining better antioxidant capacity in vegetables.

Sautéing and Nutrient Retention

Sautéing (stir-frying) can retain nutrients well if cooking times are short and moderate heat is used. Excessive heat or long cooking can degrade heat-sensitive vitamins. Using acidic ingredients like lime juice might reduce harmful compound formation during frying.

Roasting, Grilling, and Nutrient Loss

Roasting or grilling enhances flavor through Maillard reactions but can degrade certain heat-sensitive nutrients (like vitamin C, some B vitamins, and polyphenols) and may generate harmful compounds such as advanced glycation end-products (AGEs).

Canning, Freezing, and Drying

Canning subjects foods to heat and oxygen over time, often reducing vitamin C and some antioxidants but can preserve others. Nutrient retention in canned foods tends to be better than in dried foods but worse than in frozen foods. Freezing generally preserves the majority of nutrients and phytonutrients if done promptly after harvest, with some loss possible but much better retention compared to drying or prolonged cooking. Drying decreases water content and concentrates nutrients but can reduce heat- and air-sensitive phytonutrients like anthocyanins and vitamin C, especially if dried using heat.

Tips for Maximizing Nutrient Retention

• Nutrient retention is higher with shorter cooking times and reduced cooking liquid exposure.
• Cooking can increase the bioavailability of some nutrients (e.g., beta-carotene in carrots, chlorogenic acid in potatoes), even though some vitamins degrade.
• A variety of preparation methods and regular consumption of diverse fruits and vegetables ensures balanced nutrient intake and maximizes health benefits.

Nutrient-Rich Fruits and Vegetables

• Winter squash, pumpkins, and carrots contain vitamin C, vitamin A, vitamin K, vitamin B6, potassium, and carotenoids.
• Tomatoes contain vitamin A, vitamin C, vitamin K, potassium, and carotenoids.
• Peppers have vitamin A, vitamin C, vitamin B6, carotenoids, phenolics, and capsaicin.
• Green leafy vegetables contain vitamin A, vitamin E, vitamin K, vitamin B6, riboflavin, folate, magnesium, iron, calcium, and potassium.
• Apples, pears, and peaches have vitamin A, the phytochemical quercetin, which is anti-inflammatory.
• Berries contain vitamin C, vitamin K, and have the phytonutrients anthocyanins and ellagitannins.
• Melons contain vitamin C, vitamin A, vitamin B6, folate, potassium, carotenoids, and polyphenols.
• Sweet corn contains vitamin C, niacin, and carotenoids.
• Green beans and pea pods have vitamin A, vitamin C, folate, and phytonutrients including carotenoids, chlorophyll, polyphenols, and saponins.
