Role of nutrition on preventing gastric cancer
Excessive salt intake, often associated with a diet rich in pickled and smoked foods, has been linked to an increased risk of gastric cancer. To minimise this risk, it is advisable to adopt a low-sodium diet and consume plenty of fruits and vegetables. Current evidence does not support the effectiveness of dietary supplements like garlic and antioxidant vitamins (e.g., A, C, E) in reducing the risk of gastric cancer.
Nutritional challenges after a gastric cancer diagnosis
Gastric cancer treatments, such as surgery, chemotherapy, and radiation therapy, can lead to a variety of side effects that impact a patient’s ability to eat and absorb nutrients. These side effects are collectively referred to as Nutrition Impact Symptoms (NIS).
Examples of nutrition impact symptoms include:
- Loss of appetite
- Early satiety (feeling full after eating a small amount of food)
- Nausea
- Vomiting
- Difficulty in swallowing
Reduced nutritional intake can lead to unintended weight loss, muscle loss and malnutrition.
Dietary recommendations for post-gastric cancer treatment
After gastric cancer treatment, a high-protein, high-calorie diet can help maintain weight, preserve muscle mass, and aid in recovery. Prioritising protein-rich foods like fish, eggs, poultry, dairy, soy products, beans, and legumes is crucial. If you are struggling with appetite or unable to meet your nutritional needs, a registered dietitian may recommend oral nutritional supplements tailored to your specific condition.
Tips to follow a high energy high protein diet:
- Small, Frequent Meals: e.g., aim for 3 main meals and 3 smaller snacks throughout the day.
- Prioritise protein-rich foods at each meal.
- Drink high-calorie, nutrient-dense liquids like milk smoothies or oral nutritional supplements between meals.
- Consume your largest meal when you feel most energetic and hungry.
- Focus on enjoying your favorite foods rather than forcing yourself to eat what you don’t like.
- Add healthy fats like oils or sugar to increase the calorie content of your meals.
