Diet and Food Guidance for Itching

Food does not cause most itching, but diet can help in some conditions and trigger it in others.

Foods that may help the skin

• Plenty of water through the day
• Fruits and vegetables for vitamins and fibre
• Foods with healthy fats such as nuts, seeds, fish and mustard or olive oil in normal amounts
• Home-cooked, simple meals

Possible triggers

• A true food allergy (such as nuts, eggs, milk, shellfish) can cause hives and itching soon after eating. Avoid the food and see a doctor.
• Very spicy food and alcohol may increase itching in some people by making the skin feel warm.
• Hot drinks can worsen heat-related itching.
• Some people notice that certain foods worsen eczema. Keep a food diary before cutting foods out.

Do not cut out food groups without advice

Strict elimination diets, especially in children, can cause poor growth and nutrient gaps. Speak with a doctor or dietitian first.

Diet for related conditions

• With diabetes, steady blood sugar control helps reduce itching.
• With liver or kidney disease, follow the diet your doctor gives you.
• With iron deficiency, the doctor may advise iron-rich foods or supplements after a blood test.

Ayurvedic dietary advice

Ayurveda suggests avoiding sour, salty, fermented, very spicy and oily foods, and mixing milk with fish or sour items, when skin is itchy. Favour light, freshly cooked food with bitter greens such as bitter gourd. This is a traditional guide and evidence is limited.

Supplements

Do not start herbal or vitamin supplements for itching without advice. Some can harm the liver.

Key point

Eat a balanced diet, drink water, and avoid foods that clearly trigger your itching.

Before your appointment

Note when the itching began, where it is, what makes it better or worse, and whether it is worse at night. List all medicines, creams, herbs and soaps you use, and any new foods or products. Mention others at home with itching, rash, weight loss, night sweats, yellow eyes, dark urine or tiredness. Bring photos of any rash that comes and goes. Ask about tests, the safest treatment and the signs that need urgent care. Call 112 for swelling of the face or lips or trouble breathing.
