​How to have a healthy summer and a gut friendly picnic

There are plenty of simple and delicious ways to add both prebiotic and probiotic foods and other nutrient dense foods to your picnic and summer events ensuring that you are both nourishing your gut and your palate.

During the summer, it’s incredibly easy to kick back, make the most of the weather and sometimes get carried away with that being out of school vibe. As sun makes more of an appearance, the desire to spend time outside increases and with that relaxed feeling, our attention on our diet and nutrition often wanes. Summer parties, picnics and barbeques often lead us to increase alcohol consumption, sugary foods such as ice-cream and cakes and decrease in fruit and vegetables. All of this sometimes puts our system out of sync which may be linked with the decline of the beneficial bacteria in our guts.

Hippocrates once said ‘ All disease starts in the gut” and being healthy is often thought to be the absence of disease. Given our gut health is often a mirror of our overall health, it’s incredibly important to maintain our gut microbiome and ensure its diversity. So how can you ensure that you look after this important symbiotic relationship and still have a fun and tasty summer?

Firstly, being conscious of eating and drinking things that might affect our gut health is important and think about simple swaps or tips:

There are plenty of simple and delicious ways to add both prebiotic and probiotic foods and other nutrient dense foods to your picnic and summer events ensuring that you are both nourishing your gut and your palate. Prebiotic foods are those that promote the growth of the beneficial bacteria in your gut whilst probiotics are foods which include live bacteria. For me, the easiest way to improve both gut health and overall health over the summer season is to make vegetables and fruit the basis for meals to ensure that you are getting plenty of fibre which provides a great source of nutrients for beneficial bacteria in your gut. Ideas for a gut healthy picnic might include:

Here of three of my easy summer favourite ingredients to add to your menu to help you enjoy gut health over the summer.

Berries –

British berries are at their sweetest and juiciest during the summer months and are packed with phytochemicals, polysaccharides and polyphenols which provide food for the gut microbiota. Berry anthocyanins can inhibit oxidative damage to cells and decrease the risk of disease by limiting dangerous anaerobic bacteria . There is evidence to demonstrate that cranberries have proanthocyanidins which potentially inhibit pathogenic microbiota such as uropathogenic E coli by preventing gut colonisation[ii]. Berries are perfect for dessert or snacking or even try add berries to salads or in salsas which are often fruit based or even in gazpacho. Discover some strawberry recipes here

Onions and garlic –

Onion and garlic are high in allyl sulphides such as allicin which has potent microbial activity against pathogenic bacteria such as Staphylococcus aureus and E. coli [iii]. They are also high in inulin, a non-digestible prebiotic which passes through both the large and small intestine unabsorbed. The beneficial bacteria in the gut such as Bifidobacterium ferment the inulin and this impacts the lining of the gut and stimulates beneficial bacteria to grow[iv]. Onions and garlic are great for adding flavour to a range of dishes, particularly marinades and dressings. Try my spicy chicken skewers with pineapple salsa to make the most of these ingredients.

Live yoghurt –

Milk sugars, lactose, are fermented by lactic bacteria in milk to make live yoghurt which is full of protein, calcium and vitamin D as well as beneficial bacteria. Some of these probiotics in live yoghurt have been to shown to reduce symptoms of irritable bowel syndrome (IBS) including bloating and stool frequency [v]. There are many studies demonstrating that live yoghurt improves bowel habits in women with no diagnosed bowel issues[vi]. Live yoghurt is often thought to improve the immune system function by reducing inflammation in obesity and obesity related disorders[vii]. Recent studies have demonstrated that frozen live yoghurt retains its gut health properties[viii] so look out for swapping ice-cream for frozen live yoghurt. Live yoghurt makes a fantastic alternative to mayonnaise in coleslaw or salad dressings.

RECIPE

Spicy chicken skewers with pineapple salsa

I’m a huge fan of anything that you can eat off a stick as this signifies summer to me. These chicken skewers can be popped onto the barbeque or under the grill, and eaten hot or cold with the salsa. They pack well and for both picnics or packed lunches and the salsa can be made with peaches, nectarines, strawberries or corn for summer eating.

Ingredients (serves 2)

10 mini wooden skewers, soaked in water

For chicken skewers

6 organic chicken thigh fillets, cut into 2.5cm cubes

1 clove of garlic, crushed

1 tsp of chipotle chilli paste

1 tbsp olive oil

Juice of ½ a lime

For salsa

½ a ripe pineapple (or 3 large peaches or nectarines or 200g strawberries)

1 red chilli, deseeded and finely diced

3 spring onions, finely sliced

Juice of ½ a lime

10g of coriander, finely chopped
