You’ve probably heard the saying, “You are what you eat.” While it might sound cliché, there’s some truth to it. How we feel daily is often closely linked to what we put into our bodies and how we consume it.
If you're eating a balanced diet - getting your 5 servings of fruits and vegetables, 25-30 grams of fiber, and drinking plenty of water- but still feel sluggish, bloated, or experience digestive discomfort, the issue might not be what you’re eating, but how and when you're eating it.
Why Food Combining May Affect Digestion
Even if you're consuming a variety of healthy foods, improper food combinations can sometimes lead to digestive issues like gas, bloating, constipation, diarrhea, and stomach aches. Over time, poor food combinations could contribute to more serious conditions, such as Irritable Bowel Syndrome (IBS), which often causes symptoms like indigestion and bloating.
The key to improving digestion might lie in how you combine foods. This concept has roots in ancient Ayurvedic medicine, which suggests that different foods require different enzymes to digest, and combining incompatible foods may lead to digestive discomfort.
Improving Digestion Starts with Your Eating Habits
To optimize digestion, it’s important to first adjust your eating habits. Here are some tips to help you get started:
1. Eat Consciously
One common mistake is over-consumption. In many places, especially in the U.S., portion sizes are often larger than necessary. Our brains are typically about 10 minutes behind our stomachs, meaning we might continue eating even after we’re already full.
To avoid overeating, aim to stop eating when you’re about half full or satisfied—not stuffed. This requires slowing down and being mindful of your food choices, portion sizes, and eating speed. Try to:
- Use your senses (smell, sight, taste) to determine what’s right for you.
- Keep portion sizes in check. A good rule of thumb is that your portion should be no larger than the size of your fist.
- Slow down. Take time to enjoy your meal. Eating on the go can stress your digestive system, so try to set aside dedicated time for meals.
2. Eat at Regular Times
Our bodies function on an internal clock, and setting a regular eating schedule can help improve digestion. Eating at consistent times allows your body to anticipate meals and produce the necessary digestive enzymes.
Try to eat your meals at set times each day. Stick to regular food groups—it’s okay to change what you eat, but try to keep the types of foods similar each day. Organize foods into primary, secondary, and exotic groups:
- Primary foods: eaten regularly (e.g., vegetables, grains, fruits)
- Secondary foods: condiments and additions (e.g., nuts, spices)
- Exotic foods: eaten occasionally (e.g., new or unusual foods)
By doing this, your body will know when to expect food and can digest it more efficiently.
Food Sequencing: Organize Your Meals for Optimal Digestion
To avoid a “food traffic jam” in your digestive system, it’s helpful to eat foods in a particular order. Start with foods that are easy to digest and gradually move toward those that take longer.
Here’s a rough timeline for how long different types of foods take to digest:
- Juices and water: 20-30 minutes
- Soups, fruits, or smoothies: 30-45 minutes
- Vegetables: 30-45 minutes
- Grains and starches: 2-3 hours
- Beans, poultry, meat, or fish: 3 or more hours
To avoid digestive discomfort, eat the easiest-to-digest foods first, then move to the more complex ones. Think of your digestive system as a highway: slow-moving traffic should follow faster vehicles to avoid a jam.
Sample Meal Plan Using Food Sequencing
Breakfast:
- Water or juice
- Fresh fruit
- Cereal, bagel, muffin, or protein (e.g., eggs, meat)
Lunch:
- Beverage
- Salad, fruit, or vegetable
- Sandwich, grain, beans, or meat
Dinner:
- Beverage
- Salad
- Vegetables
- Main course (bean, grain, poultry, fish, or meat)
Note: Milk and milk-based products are hard to digest and should be consumed alone, not combined with other foods. The easiest beverages to digest are water or tea (preferably unsweetened).
Understanding the Seven Food Groups for Proper Food Combining
Protein
- Protein is essential but should be consumed in moderation.
- Protein foods (like meat, eggs, and beans) take about 3 hours to digest.
- Avoid combining different types of protein (e.g., meat and beans) in the same meal, as they require different enzymes to break down.
- Protein is best paired with non-starchy vegetables (e.g., leafy greens) to prevent digestive discomfort like bloating and gas.
Starches
- Starches (e.g., bread, pasta, potatoes) require digestion through enzymes in saliva and stomach acid.
- Avoid combining starches with proteins or acidic foods (like citrus fruits) as this inhibits starch digestion, leading to incomplete digestion and bloating.
- Pair starches with non-starchy vegetables for optimal digestion.
Sugars
- Sugars are easy to digest but can interfere with starch digestion when combined.
- Avoid combining sugars with starches or proteins. For example, putting sugar on cereal or eating dessert right after a meal can cause fermentation, leading to gas and bloating.
- Artificial sweeteners (e.g., sucralose) can slow digestion and should be avoided.
Fats
- There are two types of fats: saturated (solid at room temperature) and unsaturated (liquid at room temperature).
- Saturated fats are harder to digest and should be consumed in moderation.
- Unsaturated fats (found in olive oil, avocados, and nuts) are easier to digest and should be paired with non-starchy vegetables or lean proteins.
Fruits
- Most fruits are easy to digest because they contain water, which speeds up digestion.
- Avoid combining acidic fruits (e.g., citrus, berries) with proteins or starches as they inhibit digestion.
- The best time to eat fruit is before meals or on an empty stomach to ensure it digests quickly.
Vegetables
- Vegetables are generally easy to digest, especially if they contain lots of water (e.g., leafy greens, cucumbers).
- Starchy vegetables (e.g., potatoes, squash) take longer to digest (up to 2 hours), so be mindful of the combinations.
- Non-starchy vegetables (like broccoli, spinach, and lettuce) can be paired with almost any other food group.
Non-Starchy Vegetables
- Non-starchy vegetables digest quickly and can be eaten with any food group.
- They should be eaten before starches or proteins because they digest the fastest.
Summary: Moderation is Key
You don’t have to perfectly combine every food at every meal, but moderation is crucial. By consuming more good food combinations than bad ones, you can significantly improve digestion and reduce discomfort.
