How to improve digestion & heal your gut

Has digestive discomfort become a fact of life for you? Do you believe that gas, bloating, heart burn or constipation is unavoidable? If yes, then here’s some good news: a few simple diet and lifestyle changes can a great impact on your gut health and make these digestive ailments a thing of the past.

Learn what you can do today to improve your gut function naturally and help it ‘run’ more smoothly.

1. Ditch Sugar-Laden & Highly Processed Foods

Besides being usually poor in nutrients and high in calories, processed foods are also loaded with sugar and/or high fructose corn syrup; two ingredients that lead to the production of inflammatory cytokines, ‎an excess of which has been associated with ‎digestive disorders 1.

A highly processed diet also favors the growth of pathogens in our gut. These bad bugs have no digestive function and can gradually destroy the gut’s lining and function by producing dangerous endotoxins and upsetting the delicate ecosystem in the gut. This increases the risks of developing a leaky gut, one that is unable to prevent toxins or bacteria from entering the bloodstream 2. A damaged gut also worsens inflammation.

Your action plan:

  • Start reading food labels and avoid products that list sugar among the first three ingredients or those that contain any kind of syrups (fructose, inverted, golden, glucose and so on).
  • Keep a food diary to spot foods that are high in sugar or fructose – try to reduce the consumption of these foods one at a time. For instance, if you drink 8oz of soda daily either substitute it with water every other day or gradually decrease your consumption by 1oz every week.
  • Eat more whole foods – this way you won’t have to scrutinize food labels that often.

2. Avoid industrial seed oils

Regular consumption of industrial seed oils such as canola, sunflower or soya bean oil can disturb the omega-6 to omega-3 ratio, paving the way for inflammatory processes, and may also damage the lining of your gut. 3

Your action plan:

  • Use virgin coconut oil for cooking.
  • Make your own salad dressing using extra virgin olive oil and apple cider vinegar (or any type of organic vinegar) instead of commercial dressings or mayonnaise – these often contain seed oils.

3. Overcome digestive deficits

It’s possible to have the healthiest and most nutrient-packed diet possible, but still suffer from digestive issues. It might just be age-related digestive decline.

As we age, our digestive system may become gradually less efficient at digesting food and absorbing nutrients 4. As we grow older, we experience a reduction in diversity of the gut microbiome and a decline in digestive enzymes such as: 4

  • Pepsin: The enzyme released by the stomach which initiates protein digestion.
  • Pancreatic amylase: Involved in carbohydrate digestion.
  • Pancreatic protease: Responsible for the bulk of protein digestion.
  • Pancreatic lipase: Breaks down dietary fat into monoglycerides and free fatty acids.
  • Healthy bacteria: These are also involved in vitamin production and absorption.

The role of these enzymes is to break down the food into nutrients that can be easily utilized by the body. If this process is undermined in any way, the food food you eat won’t be digested properly. This can result in problems such as excess gas, bloating, inflammatory conditions, vitamin deficiency, malnutrition, and a weakened immune system 3, 5

Your action plan:

Incorporate some of the spices below into your diet.

  • These spices can help increase bile secretion, which will improve the digestion and absorption of fat and fat-soluble vitamins, and stimulate your pancreatic enzymes and increase lipase activity 6.
  • They can also help to decrease food transit time by making the digestive enzymes and bile acid more available, thus accelerating the overall digestive process and improving nutrient absorption 7. A reduced food transit time in the intestines has also been linked to reduced risks of colon cancer, and can also alleviate constipation 7.

Turmeric. Add some turmeric powder to curries or in marinades. You can also have some turmeric tea: simply allow 1 teaspoon of finely grated fresh turmeric to steep in hot water for 3 minutes; strain; add in a quarter teaspoon of fresh lemon juice or some raw honey (optional) and drink.

Fenugreek. You can add a pinch of grounded fenugreek to mashed sweet potatoes, curries or chickpea salad. To make fenugreek tea, allow 1 teaspoon of fenugreek seeds to steep in a cup of boiling water for 5 minutes; strain and relish with a little bit of raw honey.

Garlic. Add some freshly minced garlic to stir fries, soups and curries or use whole cloves when roasting beef or grilling fish.

Ginger. Add grated ginger to stir fries or casseroles or when preparing sweet and sour dishes. You can also make ginger tea by adding a teaspoon of minced ginger to some boiling water or green tea.

Fresh pineapple 8,9 and papaya 9 have been shown to improve protein digestion in individuals who lack sufficient digestive enzymes. These two fruits contain enzymes (papain and chymopapain in papaya and bromelain in pineapple) that help breakdown protein into amino acids. Eat a slice or two of either fruit 10 minutes before your meal. You can also use the fruits in green smoothies.

The following can also improve your gut health:

  • Take a high quality probiotic.
  • Consume fermented foods regularly.
  • Avoid taking non-steroidal anti-inflammatory drugs (NSAIDs) or acid-suppressing medications.
  • Avoid alcohol.
  • Practice stress-reducing activities and sleep before midnight.
