Sea Buckthorn – a rich source of antioxidants

Thoughts from our registered nutritionist, Lucy Williamson DVM BVM&S MSc

It’s almost a year since I began working with British Seabuckthorn – as a Registered Nutritionist with a particular interest in sustainable foods, healthy for people and planet, this journey is an exciting one… British Seabuckthorn (BSB), responsibly farmed in Essex, contains an abundance of nutrients vital for long-term health and wellbeing. Packed with antioxidants, natural prebiotics, vitamins, minerals, unsaturated oils and many other beneficial phytonutrients, it’s a berry with fabulous potential.

The best food choices not only nurture human health but support the biodiversity of our ecosystems too, from healthy soils to thriving flora and fauna with essential roles to play in maintaining nature as it should be. So, as the British Sea Buckthorn Company nurture these principles in continuing to work hard to develop a crop adapted to our rather unpredictable British climate, here are a few ‘need-to-knows’ about British Sea Buckthorn!

A rich source of antioxidants 

Our everyday metabolism uses oxygen. By-products of this process are known as free radicals, which can cause damage to cells in a process known as Oxidative Stress – a key factor in ageing and chronic illness such as heart disease, stroke and cancer. We produce antioxidants all the time in our body cells which, by removing these radicals, keep our cells healthy. Many of the antioxidants we make require Vitamins C and E and British Sea Buckthorn is an excellent source of both. Our recommended daily intake of Vitamin C is 45mg; British Sea Buckthorn often contains more than 400mg/ 100g so it’s a very rich source! (current regulations concerning nutrient claims state a food must contain more than 24mg/ 100g to be ‘high in’ Vitamin C, EU Regulation No 1047/2012) Oxidative stress is higher in Obesity and Type 2 Diabetes so antioxidant need increases here too as it does after endurance or high intensity sport. BSB also contains other, powerful antioxidants including Superoxide Dismutase and Flavanoid polyphenols which have an important role in nurturing our all-important gut bacteria too.

As well as eating a more plant-based diet, we’re encouraged to eat fish at least twice weekly in order to benefit from its Omega 3 unsaturated oils. Many years of firm evidence now show the links between a good intake of Omega 3 and protection against heart disease and stroke in particular due to its anti-inflammatory role. Fish contains particularly beneficial types of Omega 3, DHA and EPA. These aren’t present in plants but a good intake of plant

Omega 3 (ALA)

Omega 3 can be used by the body to make EPA and DHA. Too much Omega 6 in the diet can restrict this process but as sea buckthorn contains far more Omega 3 than Omega 6, it has real potential here too.

Seabuckthorn as a natural Prebiotic: Fibre

FIBRE is a type of carbohydrate that can’t be digested in the small intestine. Instead, it passes to the colon (large intestine) where it’s fermented by billions of gut bacteria to produce many compounds essential for our metabolism. Collectively, the genetic make-up of these bacteria is known as our ‘Microbiome’. With 150x our own genetic makeup, our microbiome is to be nurtured; in fact, our ratio of human cells to bacterial cells is 1:1 so we’re just as much bacteria as we are human! We now know these gut bacteria have key roles in our long-term health, from optimising our immune system to protection against certain types of cancer and weight control. In addition, fibre maintains our ‘digestive health’, helping food to pass more quickly through the gut. In 2016, Public Health England, advised increasing the recommended intake of fibre for children (18g/day) and adults (30g/day), as a result of firm evidence for its health benefits, collected over several years. Sea buckthorn, along with other fruit and veg (diversity is the key to good microbes!) is a great source of fibre and also flavanoid antioxidants mentioned earlier, both of which are an important energy source for our microbiome and our gut health.

With an abundance of nutrients, too many to mention here, I’m excited to be involved with the British Sea Buckthorn story as we work together towards a sustainable food choice with so many potential benefits to our longer-term health.
