get gut happy

7th June 2018 by Jess

What if we really are what we eat? Our nutritionist Jess explains how even the best diet in the world is nothing without the ability to absorb it properly.

Optimal gut health has become a prominent focus in 21st century health. The old saying “we are what we eat” doesn’t quite hold true; instead, it should read, “we are what we digest”. If you have the best diet in the world yet can’t absorb it or can absorb only a fraction, you’re only going to reap a small percentage of its goodness.

gut-related health problems

Healthy digestion, absorption, and assimilation of food is a big job that depends on many other factors. For example, the bugs in your gut are like a rain forest – a diverse and interdependent ecosystem. They must be in balance for you to be healthy.

Too many of the wrong ones (like parasites, yeasts or bad bacteria) or not enough of the good ones (like Lactobacillus or Bifidobacteria), can lead to serious damage to your health.

When we have poor gut health and improper gut function with too many bad critters hanging out compared to healthy bacteria, health problems can arise such as obesity, diabetes, allergies, skin issues, sugar cravings, weight imbalances, autoimmunity, depression, mood swings, cancer, heart disease, fibromyalgia, eczema, and asthma.

These sup-optimal health issues are our body’s way of communicating that it needs some focus and TLC in one way or another.

Having a healthy gut becomes central to your entire health and connected to everything that happens in your body, that’s why I almost always start treating my nutrition clients’ chronic health problems by fixing their gut first.

7 Ways to Optimise Gut Flora

The best way to grow a healthy inner garden and make your gut bugs happy begins with your diet. Here are 7 ways to build healthy gut flora starting with your next mouthful:

  1. Eat whole, unprocessed, unrefined foods. One of the best ways to maintain gut health involves cutting out the sugar and refined carbs and upping gut-supporting fibre since processed foods often contain ingredients that either suppress 'good' bacteria or increase 'bad' bacteria.
  2. Serve 75% of your plate as vegetables and plant-based foods in their whole form (versus juices since the juicing process removes the fibre). Your gut bugs really love these high-fibre plant foods.
  3. Eat good fats. Omega 3 fats and monounsaturated fats, such as extra-virgin olive oil will help with decreasing inflammation, giving healthy gut bugs a chance to flourish.
  4. Remove inflammatory fats. Cut out bad, inflammatory fats like vegetable oils. Replace these with healthier oils like extra-virgin olive oil and coconut oil.
  5. Add fibre-rich foods. Nuts, seeds, fruit, vegetables, pulses and wholegrains feed healthy bacteria and provide prebiotics which feed our healthy bacteria.
  6. Add fermented foods. Sauerkraut, kimchi, tempeh, and miso contain good amounts of probiotics so your healthy gut bugs can be fruitful and multiply. Vegetables from the sunflower family (artichokes, radicchio, lettuce, tarragon, chicory and salsify) and the lily family (leeks, chives, shallots, onions, garlic and asparagus) are particularly helpful to gut bacteria.
  7. Meditate, sleep and enjoy regular gentle exercise. These three vital R&R steps are vital for a healthy gut. Gentle, non-stressful exercise is therapeutic even for serious gut diseases due do it’s anti-inflammatory effects.

These recommendations are not miracle cures. They are the actions that lead to normalised gut function and flora through better diet choices, increased fibre intake, the use of nutrients that repair the gut lining, and the reduction of bad bugs in the gut with herbs or medication.

Soluble vs insoluble fibre

There are 2 different types of fibre: soluble and insoluble. Both are important for health, digestion, and preventing diseases.

Soluble fibre attracts water and turns to gel during digestion. This slows digestion. Soluble fibre is found in oat bran, barley, nuts, seeds, beans, lentils, peas, and some fruits and vegetables. Some types of soluble fibre may help lower risk of heart disease.

Insoluble fibre is found in foods such as wheat bran, vegetables, and whole grains. It adds bulk to the stool and appears to help food pass more quickly through the stomach and intestines.

so how much fibre should we be getting?

The Scientific Advisory Committee on Nutrition (SACN), who looked at the role of fibre in maintaining good health, published these new recommendations in July 2015:

  • adults 16 years and over: 30g per day
  • 11-16 years: 25g per day
  • 5-11 years: 20g per day
  • 2-5 years: 15g per day
shop snacks that are a source of fibre
