Diet plays an important and prominent role in every disease as food can both treat the disease and also act as a problem enhancer. Here are some best foods for the management of the disease called hiatal hernia: -

• Fresh fruits: Fresh veggies and fruits are always healthy. Fruits contain antioxidants that help in reducing the risk of occurring this disease. The fruits include cherries, blueberries, bananas, and apples.
• Whole Grains: Increasing whole grains instead of flour in your diet will increase fibre and maintain blood sugars. Thus, whole grains are mostly recommended by all the experts. Grains include cereal, bran, and oatmeal.
• Lean meats: Other fatty meats can be harmful and can promote this disease. Thus, eat lean meat including mackerel and cod. Bake this meat other than frying.
• Water: Drink maximum water as much as one can as water is the biggest treatment of this disease, and it is highly recommended.
• Low-fat products: Dairy products with low-fat are only suggested and also food with less sugar. Drink fruit juice other than tea. Other low-fat food includes yoghurt and ice-cream. 

Some of the foods that a sufferer of this disease should definitely avoid are: -

• Saturated Fats: Highly rich butter, meat, and cheese should be avoided. This comes mostly in animal-based products like milk, meat, and other dairy products.
• Beverages: The alcohol and caffeine products like wine, beer, coffee or whole milk should be avoided completely as the disease gets worse with the intake of these beverages.
• Sugar: Sugar is almost harmful in every disease as it promotes fat and that may lead to further diseases like a hernia.
• Citrus products: Avoid all the citrus products including fruits like lemons, oranges, and grapes. These foods are highly acidic thus always suggested to avoid them.
• Spicy food with onion and garlic: These foods weaken the food pipe wall making it easier for stomach acids to back up into your oesophagus. Onions and garlic are also suggested to avoid as they may cause heart bum symptoms. 

• Cook food by using healthy fats like coconut, avocado, and olive oils.
• Eat in a calm and relaxing manner and relax more.
• Always remain in a touch with your doctor.
