The researchers also reported that quercetin, quercetin-3-O-beta-D-arabinofuranoside, and phenolic compounds, such as caffeic acid, had potent antioxidant properties. The bioactive flavonoids included the antioxidant quercetin and quercetin compounds, such as quercetin-3-O-beta-D-glucopyranoside which have antiproliferative properties against liver cancer cells and breast cancer cells. The researchers identified 29 compounds, including triterpenoids, flavonoids, organic acids, and plant sterols with antiproliferative (anti-cancer) and antioxidant activities. Varieties of apples with bright colors, such as Red Delicious, have the highest levels of flavonoid pigments.Ī study by He and Liu (2008) reported that Red Delicious apple peels contained bioactive phytochemicals. The peels or skin of Red Delicious are rich in polyphenol antioxidants, including the pigments anthocyanins and anthocyanidins. Red Delicious is relatively high in calories and carbs compared with other apple varieties (only Fuji variety has higher calorie and carb contents among the five best-known apple varieties profiled in this article). Some subvarieties have an elongated shape while others are rounder. It is known for its rich, deep red color and sweet, crispy flavor. Red Delicious apple is probably the best-known variety in the U.S. Source: USDA Red Delicious apple nutrition Red delicious apples are rich in calories.

The calcium content (7mg per 100g of apples) is significantly higher than the calcium contents of Granny Smith (5mg), Red Delicious (5mg), Fuji (6mg), and Honeycrisp (4 mg). Gala apple originated in New Zealand as a cross between Kidd’s Orange Red and Golden Delicious. Source: USDA Gala apple nutrition Gala apples have calories and high mineral contents.
