custard apple, also known as Annona seeds, are from fruits like soursop (Annona muricata) or custard apple (Annona reticulata). While the fruits of these plants are commonly consumed and are generally considered safe, the seeds are another matter.

Potential Risks of custard apple:

1. Toxicity:

   • Annona seeds contain compounds that can be toxic. For example, soursop seeds contain annonacin, which is a neurotoxin and may have harmful effects if consumed in significant amounts.
   • Ingesting the seeds can pose risks to both the mother and the developing fetus, potentially leading to adverse effects.

2. Lack of Reliable Data:

   • There is limited scientific research specifically on the safety of consuming Annona seeds during pregnancy. Because of this lack of reliable data, it's best to err on the side of caution.

General Pregnancy Nutrition Advice:

1. Consult Healthcare Providers:

   • Before consuming any unusual or less commonly eaten foods during pregnancy, it's advisable to consult with a healthcare provider or a registered dietitian.

2. Focus on a Balanced Diet:

   • A diet rich in fruits, vegetables, whole grains, lean proteins, and healthy fats is generally recommended for a healthy pregnancy.

3. Avoid Known Toxins:

   • Certain foods and substances are known to be harmful during pregnancy, such as alcohol, certain types of fish high in mercury, and unpasteurized dairy products.

Given the potential risks associated with Annona seeds and the general lack of safety data, it is advisable to avoid consuming these seeds during pregnancy. If you have any concerns or questions about specific foods and their safety during pregnancy, discussing them with your healthcare provider is the best course of action.
