Improve your gut health to help support fertility- What exactly ARE prebiotics and Probiotics?

All health starts with the gut! If nutrients cannot be digested and/or absorbed from our food correctly then this will have an impact on all body organs and systems in some way, including the reproductive system.

It is important to ensure that the gut is full of healthy microbes which are balanced, as these form an ecosystem that works closely together forming many interconnections (this is known as the Microbiome). This finely tuned ecosystem is important for a healthy body and mind as it is involved in the effective absorption of vital nutrients, enhancing the immune system and helping to reduce inflammation in the body, turning off genes, turning on enzymes, helping in the reduction of anxiety and depression and the ageing process (to name a few). A diet high in sugar and fat may negatively affect the gut microbiome and may contribute to certain conditions such as insulin resistance. Some gut bacteria form vitamin K and short-chain fatty acids such as butyrate, acetate and propionate. These short-chain fatty acids are the main nutrient source of the cells lining the colon. They promote a strong gut barrier that helps keep out harmful substances, viruses, and bacteria which helps reduce inflammation.

It is important to ensure that the gut is full of healthy, diverse bacteria at least 3 months before conception for a variety of reasons. These reasons include: for the effective absorption of vital nutrients, enhancing the immune system, and also to reduce inflammation in the body. The health of a mother’s gut is vital prior to conception and it has been linked in studies to reduced eczema, asthma and coeliac disease risk, along with improved immune function in children (to name a few

How can healthy gut bacteria be improved?

  • Consume a good variety of prebiotic foods as these will help to support probiotic bacteria.
  • Consume some fermented foods such as sauerkraut or kefir to support gut flora.
  • Consume foods containing probiotic bacteria.
  • Consider taking a probiotic supplement (check with your GP or Nutritional Therapist/Dietician)

What are prebiotics and probiotics?

Prebiotics are important in our gut as they help the growth of good bacteria (Probiotics). They come mostly from carbohydrate fibers called Oligosaccharides. As they are not digested, they remain in the digestive tract and encourage the good bacteria such as Bifidobacterium and Lactobacillis to grow.

Prebiotics are naturally found in fruit, vegetables and wholegrains. Good sources are garlic, onions, leeks, berries, oats, Jerusalem artichoke and bananas.

Probiotics are useful live bacteria such as Bifidobacterium and Lactobacillis which help to maintain the balance in the digestive system and help to keep it healthy.

Probiotic sources are: yoghurt containing live bacteria culture, kefir, kombucha, cheese that is not baked, sauerkraut, kimchi, miso and fermented milk. Some foods also have probiotics added to them.

Some of those foods can also be considered synbiotic, because they contain both beneficial bacteria and a prebiotic source of fibre for the bacteria to feed on such as sauerkraut and kefir.

Roasted onions recipe – a great source of prebiotics!

Ingredients: (makes 2 portions)

4 small and medium yellow or red onions

1 tablespoon of extra virgin olive oil

1 tablespoons unsalted butter, thinly sliced

Pinch of coarse sea salt

Preheat the oven to 180 degrees Celsius. Cut the tops off of each onion, but leave most of the skins on the onion. Arrange the onions in a baking dish. Drizzle the olive oil over the onions. Place a thin slice of butter on each onion.

Sprinkle generously with salt and pepper and top with a rosemary sprig.

Bake for 35 minutes or until tender.
