I can give you some advice. Every pregnant woman's physical condition and preferences are different, so it is best to take the following suggestions before consulting your doctor or professional dietitian.

For 7-month-old pregnant women, dinner should provide enough nutrition, while taking into account digestion and comfort. Here are some dinner options suitable for pregnant women:

1. Food is rich in protein: fish, poultry, beans, nuts and tofu are all good sources of protein. These foods contribute to the growth and development of the fetus.

2. High-fiber foods: Foods rich in fiber such as vegetables, fruits, whole wheat bread and brown rice can help prevent constipation and other digestive problems.

3. Foods with high calcium and iron content: milk, yogurt, cheese, green leafy vegetables and red meat are all good sources of calcium and iron. These nutrients are essential for the bone and blood health of pregnant women and fetuses.

4. Avoid eating raw meat: In order to prevent food-borne diseases, pregnant women should avoid eating raw meat, such as sashimi, raw egg yolk and raw meat products.

5. Control food intake: Pregnant women should avoid overeating, especially high-sugar and high-fat foods. Proper control of food intake helps to maintain healthy weight gain.

The most important thing is that pregnant women should make a diet plan that suits them according to their physical condition and the doctor's advice. If you have any special dietary needs or health problems, please consult a professional doctor or dietitian.
