The healthy debate between cooked vegetables and raw vegetables | GMA

Summary

In this informative segment, registered dietitian and nutritionist Maya Feller discusses the impact of cooking methods on the nutritional value of various vegetables. She reveals that while some nutrients like lycopene in tomatoes are enhanced by cooking, others such as beta-carotene in carrots become more potent when boiled. Feller also highlights the benefits of consuming raw garlic for its anti-cancer properties and emphasizes the importance of pairing fat-soluble vitamins with olive oil for better absorption. The segment encourages viewers to consider their cooking methods to maximize the nutritional benefits of their vegetables.

Takeaways

• 🥦 Broccoli is a nutrient powerhouse, rich in vitamin K, C, folate, fiber, and antioxidants, which help reduce damaging free radicals in the body.
• 🍅 Tomatoes are a great source of lycopene, which has been linked to a reduced risk of heart disease and decreased chances of developing some cancers. Cooking tomatoes with high heat can increase their antioxidant activity and lycopene content.
• 🥕 Carrots are high in beta-carotene, and boiling them makes the beta-carotene more potent, suggesting that cooked carrots may be more beneficial.
• 🥗 Cooking tomatoes in olive oil is recommended as it increases the plasma lycopene, which is linked to heart health benefits.
• 🥦 The way you prepare vegetables can significantly affect the amount of nutrition you get from them, with some vegetables offering more benefits when cooked.
• 🥕 Raw garlic has strong anti-cancer components, but cooking it can also be beneficial depending on the dish.
• 🌿 Leafy greens are rich in fat-soluble vitamins A, D, and K, and consuming them with a little bit of olive oil can enhance their nutritional benefits.
• 🍅 Lycopene in tomatoes is better absorbed when cooked, especially when combined with olive oil.
• 🥦 The nutritional value of vegetables can vary depending on whether they are eaten raw or cooked, and understanding these differences can help maximize their health benefits.
• 🥬 Cooking methods such as boiling and using olive oil can enhance the bioavailability of certain nutrients in vegetables.
