Introduction
If your physical condition is good and gastrointestinal function is normal during the preconception period, onions can be consumed in moderation as a nutritious food supplement. They contain vitamin C, folic acid, selenium, and other components that help enhance immunity and promote metabolism. The sulfides present in onions can also assist in regulating blood lipid levels, providing essential nutritional support for preconception. Moderate consumption generally does not cause adverse effects on the body.

Whether or not to eat onions during the preconception period should be determined according to individual physical condition and gastrointestinal status. If the body is healthy and the gastrointestinal tract is adaptable, moderate consumption of onions may be acceptable. However, if the gastrointestinal tract is sensitive or prone to bloating, consumption should be cautious. Detailed analysis is as follows:

If the body's condition is good and gastrointestinal function is normal during the preconception period, onions can be consumed in moderation as a source of nutritional supplementation. Onions contain vitamin C, folic acid, selenium, and other components that help enhance immunity and promote metabolism. Additionally, sulfur-containing compounds in onions can assist in regulating blood lipid levels, providing foundational nutritional support for preconception preparation. When cooked thoroughly, the irritant properties of onions are reduced, and moderate consumption generally does not cause adverse effects.

If gastrointestinal function is inherently weak or there are existing issues such as bloating or acid reflux, the pungent and irritating components in onions may stimulate the gastrointestinal mucosa, potentially causing discomfort such as bloating and abdominal pain, which can affect nutrient absorption and overall physical condition. Some women may be particularly sensitive to certain foods during the preconception period, and the distinct odor and taste of onions might worsen symptoms like nausea and reduced appetite. In such cases, it is recommended to reduce or avoid onion consumption.

If gastrointestinal discomfort occurs after consuming onions, adjust the diet promptly. Maintain a balanced daily diet and consume more foods rich in protein, iron, calcium, and other essential nutrients to create a favorable physical environment for preconception preparation.
