To ensure the freshness and quality of the ingredients, 2 dedicated researchers were jointly responsible for the procurement of fresh ingredients, which were purchased through regular channels on Monday, Wednesday and Friday mornings.~Ingredients will be delivered three times a week for a 12-week intervention period. The initial food items to be sent include: 90g of fish rich in omega-3 fatty acids; 300g of vegetables and/or legumes, and 200g of fruits; 30g of nuts; and a cup of probiotic yogurt.~Guided dietary follow-up was conducted through video viewing and WeChat or telephone follow-up. The researcher will provide cooking instruction or dietary pattern guidance by sending videos every two weeks."
