Hi,
I would like to congratulate you first!
Dry fruits like different nuts, raisin, dates you can have but in limited amounts, as they are good source of calorie, carbohydrates and saturated fat but they also have other nutrients like, almond, walnut are good source of protein and omega 3 fatty acids, dates, raisins are souce of iron. It will be better to drink normal double toned milk and have home made curd, but packaged curd is fine. Honey is better than refined
sugar, so yes you can have lemon grass tea with honey once in a day. You should follow a balanced diet which meet the needs of all the nutrients, which is required during pregnancy.
