This is a common type of information about food combinations that could be harmful to health, but many of these claims may not be accurate or are exaggerated. Currently, there is no clear scientific evidence that combining certain foods will lead to "toxicity" or cause cancer.

Here are a few basic points to consider about food combinations:

Soybeans and cruciferous vegetables: There are rumors that eating soybeans along with cruciferous vegetables can negatively affect the thyroid, but this only happens in cases of excessive consumption, and more research is needed to confirm this.

Alcohol and grilled meat: Overcooked grilled meat can produce harmful compounds (such as PAHs and HCAs) that are linked to cancer. Combining this with alcohol may increase the risk of harm to the body.

Tomatoes and cucumbers: There's a rumor that this combination negatively affects digestion, but there is no clear scientific evidence to support the claim that this combination is harmful to health.

The key is to maintain a balanced and varied diet, avoiding focusing too much on unproven warnings. If you have concerns about your health, it is best to consult with a doctor or nutritionist.
