Side effects of leafy green vegetables

If you have thyroid issues, it’s best to moderate your intake of raw leafy greens.
Allergic reactions: Although rare, some individuals may experience allergic reactions to leafy greens. Symptoms can include itching, swelling, or digestive upset.If you suspect an allergy, it’s best to avoid the offending vegetable and consult a healthcare professional for testing.
