They function as powerful antioxidants in the human body, which means they help neutralize harmful free radicals and reduce cellular damage, similar to how a shield protects against arrows.
- 3.
A higher intake of Anthocyanins has been linked to several significant health benefits, including improved cholesterol levels, better eye health, and a reduced risk of heart disease, certain cancers, and diabetes.
- 4.
The concentration of Anthocyanins varies significantly across different foods; for instance, purple potatoes can contain up to 800 milligrams per cup, while blueberries typically have around 600 milligrams per cup, and purple sweet potatoes about 500 milligrams per cup.

Frequently Asked Questions
61. UPSC often tests specific data points. What are the key numerical details related to anthocyanins that aspirants frequently confuse or overlook, especially regarding their economic impact and concentration?
Aspirants often overlook the stark contrast in market prices and farmer profitability. Purple potatoes, rich in anthocyanins, fetch around Rs 28 per kilogram wholesale, while normal potatoes sell for merely Rs 2-3 per kilogram during low-price seasons. This translates to a significantly higher profitability for farmers, potentially earning Rs 6 lakh to Rs 20 lakh per acre from anthocyanin-rich crops, far exceeding traditional varieties. Additionally, remember the concentration differences: purple potatoes can have up to 800 mg per cup, blueberries around 600 mg per cup, and purple sweet potatoes about 500 mg per cup. Also, the National Horticulture Mission offers a 50% subsidy for net house units to promote such high-value crops.
Exam Tip
Create a small table or flashcard comparing the prices (wholesale, farmer income) and concentrations (mg/cup) for different foods. Pay close attention to the units (Rs/kg, Rs/acre, mg/cup) as UPSC often swaps them.
