The use of silicone bowls is safe, provided that they are made of food grade silicone material. These silicone bowls usually meet food safety standards and do not have direct harmful effects on the human body. The following are precautions when using silicone bowls:

1. Food grade materials: Silicone bowls are usually made of food grade silicone, which meets food safety standards.

2. Non toxic and odorless: Silicone itself is a non-toxic and odorless material, and will not release harmful substances under normal use conditions.

3. High temperature resistance: Silicone has good high temperature resistance and can usually withstand high temperature cooking and microwave heating.

4. Easy to clean: The surface of the silicone bowl is smooth, does not absorb food residues, is easy to clean, and can be washed by a dishwasher.

Although silicone bowls are considered relatively safe, the following points should still be noted:

● Purchase reliable brands: Choose well-known and reputable brands to purchase silicone bowls to ensure they meet relevant safety standards.

● Not suitable for extreme temperatures: Although silicone is resistant to high temperatures, it should not be used directly in open flames or ovens to prevent possible damage.

● Avoid scratching: Avoid using sharp objects to scratch the silicone bowl to prevent surface damage.

Under normal use, silicone bowls have no direct harmful effects on the human body. However, if you have any concerns about a specific brand or material, it is best to consult with relevant professional organizations or doctors for advice.
