55. Shiitake Mushrooms: The Functional Fungi

Shiitake mushrooms, a staple in many cuisines, are an excellent addition to any blood-sugar-conscious diet. They contain a compound called lentinan, which has been shown to support healthy blood sugar levels. Shiitake mushrooms are also a good source of fiber, which slows digestion and helps prevent rapid glucose spikes. Additionally, they are rich in antioxidants and anti-inflammatory compounds that support overall health. Sautéed, roasted, or added to soups, shiitake mushrooms are a delicious and functional way to support your metabolic health.

56. Red Onion: The Flavonoid-Rich Carb

Red onion is a versatile vegetable that offers a surprising benefit for blood sugar management. It contains a high concentration of quercetin, a powerful antioxidant that has been shown to improve insulin sensitivity and support healthy blood sugar levels. Red onions are also rich in fiber, which slows digestion and helps prevent rapid glucose spikes. Add them raw to salads, sandwiches, or tacos for a crunchy, flavorful boost. Their natural sweetness satisfies without spiking blood sugar, making them a versatile and flavorful ally.
