How to Combine Foods for Better Digestion: Essential Do’s and Don’ts

Updated: Nov 12

I learnt in my childhood that when you eat, you should ideally not eat meat together with starches or tomatoes together with sour cream. Back then it was not explained why it's not recommended to combine these foods. Having learnt more about it in recent years through my nutrition studies, I am sharing what I have learnt below.


How to improve digestion?

Certain food combinations can make digestion harder for some people due to differences in digestion rates, enzyme needs, and acid requirements. Most of all it's important for you to take notice how you feel after eating. If you feel bloated, if you feel gassy, if you experience pain- it could be that you are combining foods together that can cause these digestive discomforts for you.


Here are some combinations that might be best avoided if you have sensitive digestion or are prone to digestive discomfort:


1. Protein and Starch (e.g., Meat and Potatoes, Burger and Fries)

  • Why: Proteins and starches require different enzymes and pH levels. Proteins need acidic conditions, while starches are best digested in a more alkaline environment.

  • Result: Eating them together can slow digestion and lead to bloating or gas for some people.

  • Tip: Try combining protein with non-starchy vegetables (like greens) instead, or eating starchy foods with vegetables separately.


2. Fruit with Other Foods (e.g., Fruit with Yogurt or Meat)

  • Why: Fruits digest more quickly than most other foods, and if they’re combined with slower-digesting foods, they may ferment in the stomach.

  • Result: This can lead to gas, bloating, or discomfort.

  • Tip: Eat fruits alone, ideally 30 minutes before a meal, or as a light snack in between meals. Some fruits, like bananas, may combine better with other foods, but generally, fruits are digested best on their own.


3. Dairy and Meat (e.g., Cheeseburger, Creamy Meat Sauces)

  • Why: Dairy and meat are both rich in protein and fat, which can be heavy on the digestive system. Dairy also requires specific enzymes, like lactase, which not everyone produces in sufficient amounts.

  • Result: Digestive discomfort, such as gas and bloating, especially if you’re lactose intolerant.

  • Tip: For better digestion, keep dairy and meat separate or enjoy small amounts to minimise potential discomfort.


4. Two High-Protein Foods (e.g., Bacon and Eggs, Meat with Beans)

  • Why: Proteins take time and energy to digest, and eating two types of protein can overwork the digestive system.

  • Result: This can lead to slower digestion and cause fatigue or bloating.

  • Tip: Stick to one type of protein per meal, like eggs with vegetables or beans with rice.


5. Sugary Foods and Protein (e.g., Dessert After a Steak Dinner)

  • Why: Sugary foods digest quickly, while proteins digest more slowly. When sugar is combined with protein, it may ferment in the stomach.

  • Result: This can lead to gas, bloating, and slower digestion.

  • Tip: Save sweet foods or desserts for at least an hour or two after a meal or enjoy them on their own to reduce digestive strain.


6. Water with Meals

  • Why: Drinking a lot of water during a meal can dilute stomach acid, making it less effective at breaking down food.

  • Result: This may slow digestion and lead to discomfort for some people.

  • Tip: Sip small amounts of water if needed, but for optimal digestion, it’s best to drink water 30 minutes before or after meals.


7. Fats and High-Sugar Foods (e.g., Ice Cream, Pastries)

  • Why: Fats slow down the digestion of sugars, which can cause blood sugar spikes and make digestion sluggish.

  • Result: This combination can lead to digestive discomfort, bloating, and an increased risk of weight gain over time.

  • Tip: Enjoy high-fat foods separately from sugary treats, or consider options with natural sugars and healthy fats if desired.


8. Acidic Fruits and Starches (e.g., Oranges with Toast or Oatmeal)

  • Why: Acidic fruits like citrus can interfere with the digestion of starches and make it harder for enzymes to do their job.

  • Result: This can lead to fermentation and bloating.

  • Tip: Enjoy acidic fruits on their own or combine them with proteins or leafy greens, which tend to pair better.


General Tips for Better Digestion

  • Eat Smaller Portions: Large meals can overwork the digestive system, so try to eat smaller, balanced meals throughout the day.

  • Chew Well: Chewing thoroughly helps break down food and mix it with saliva, which aids digestion.

  • Listen to Your Body: Everyone's digestion is different, so notice what combinations work best for you.


While not everyone is affected by these combinations, being mindful of them may help improve digestion, reduce discomfort, and promote overall gut health.
