I can tell you that nectarines affect pregnant women in many ways. First of all, nectarine is a nutritious fruit, rich in nutrients such as vitamin C, vitamin A, fiber and antioxidants, which is very beneficial to the health of pregnant women.

However, pregnant women need to pay attention to the following points when consuming nectarines:

1. Temperature: Pregnant women should avoid consuming nectarines that are too hot or too cold, so as not to cause indigestion or oral discomfort.

2. Freshness: Choose fresh, ripe nectarines and avoid overripe or spoiled fruits to avoid food poisoning.

3. Allergic reaction: Some pregnant women may be allergic to nectarines. If allergic symptoms such as rashes, difficulty in breathing and swelling of the throat occur, they should stop eating immediately and seek medical attention.

4. Pesticide residues: Try to choose organically grown nectarines to minimize the risk of pesticide residues. If you are unsure whether a nectarine is organic or not, soak it in salt water for a while and then rinse it off with water.

Overall, eating fresh, ripe nectarines in moderation is safe for pregnant women and provides a wealth of nutrients. However, if you have any specific health questions or concerns, it is recommended to consult your doctor or obstetrician for personalized advice.
