Food Combinations to Avoid: What You Need to Know

Share It!

Nutrition plays a crucial role in our health and well-being, and this extends not only to the quality of the foods we eat, but also to how we combine them. Certain food combinations can cause digestive discomfort, interfere with nutrient absorption, and even affect our long-term health. In this article, we’ll explore some combinations that are best avoided and the reasons behind these recommendations.

  1. Fruit with Heavy Meals
    Fruits are fast-digesting foods. When consumed after heavy meals, they can ferment in the stomach, leading to bloating, gas, and discomfort. This is because fruits require a different stomach environment than meals rich in protein and fat, which take longer to digest. To avoid problems, choose to eat fruit alone or as a light snack.
  2. Dairy with Acidic Foods
    Combining dairy products (like milk or yogurt) with acidic fruits (like oranges, lemons, or pineapples) can cause the milk to curdle in your stomach, making it harder to digest. Additionally, this combination can cause discomfort and a feeling of heaviness. If you enjoy smoothies or shakes, consider using less acidic fruits or avoiding dairy with citrus fruits altogether.
  3. Starchy Meats
    Combining proteins (like meat, chicken, or fish) with carbohydrates (like rice, potatoes, or bread) can be challenging for your digestive system. Each type of food requires different enzymes to digest, which can lead to slower digestion and symptoms like bloating and gas. For more efficient digestion, try eating proteins and carbohydrates at separate meals.
  4. Starchy Foods with Sugar
    Eating starchy foods (like chips or bread) along with sweet desserts can cause blood sugar spikes. Combining complex and simple carbohydrates can result in short-lived energy followed by a crash, leading to fatigue and excessive hunger. To avoid this, choose a single source of carbohydrates per meal and keep sweets to a separate time.
  5. Fish with Dairy
    The combination of fish and dairy is considered hard on the digestion and can cause gastrointestinal discomfort in some people. Fish digests more quickly than dairy, and the combination can cause fermentation in the stomach. For best digestive results, choose to consume fish with vegetables or whole grains.
  6. Nuts and Dried Fruits with Heavy Meals
    While nuts and dried fruits are healthy, consuming them in large quantities with other heavy foods can make digestion more difficult. These foods are rich in fiber and healthy fats, but they can cause discomfort if not digested properly. Consider consuming nuts and dried fruits as stand-alone snacks to optimize digestion.
  7. Coffee or Tea After Meals
    Caffeinated beverages, such as coffee or tea, can interfere with the absorption of iron and other nutrients if consumed immediately after a meal. Additionally, caffeine can increase stomach acid, leading to digestive discomfort. To maximize nutrient absorption, wait at least 30 minutes after a meal before drinking any caffeinated beverages.
  8. Alcohol with High-Fat Foods
    Combining alcohol with fatty foods can overload the liver and cause gastrointestinal discomfort. Alcohol and fat are metabolized differently, and the combination can cause bloating and discomfort. For the healthiest way to consume alcohol, limit alcohol with heavy meals and consider lighter food options.
  9. Raw Vegetables with Protein
    Some raw vegetables, such as broccoli and cauliflower, can be difficult to digest when consumed with protein, leading to gas formation. To avoid discomfort, consider cooking vegetables before combining them with protein or eating them as a light snack.
  10. Juices with Solid Foods
    Drinking juices, especially processed ones, with meals can dilute the digestive juices in your stomach, which can harm your digestion. For best results, choose to drink juices before or after meals, allowing your stomach to work more efficiently.


The food combinations we make have a significant impact on our digestion and overall well-being. While some people may tolerate these combinations without problems, it is always good to listen to your body and observe how it reacts to different food combinations. By becoming aware of the combinations that may cause discomfort, you can make more informed decisions about your diet, promoting healthy digestion and a more balanced lifestyle.
