For friends who like eating winter jujubes, being able to eat winter jujubes that are in season is best, so you need to know clearly when winter jujubes ripen and come on the market.

2. Generally, winter jujubes can be picked in batches from early October, and the picking time is after the morning dew has dried, which is more conducive to storage. In addition, the degree of ripeness at picking has a relatively large impact on storage life. The lower the ripeness of winter jujube, the more storage-resistant it is, and the initial red fruit (coloration below 25%) is the most storage-resistant. So if picking for fresh eating, do it when half-red; if for processing, you can choose to pick at the initial red stage.

Generally, diabetic patients had best avoid eating winter jujubes; if they really want to eat, they can eat one or two to have a taste.

3. Winter jujube should not be eaten too much at one time, nor on an empty stomach, because the jujube skin is relatively hard and contains crude fiber, so it is not very easy to digest. If eaten in large amounts on an empty stomach, it will burden the stomach and intestines and make them feel uncomfortable.
