BEETROOT BENEFITS
I hadn't planned a post about beetroot, but when I sliced this one the colour was just so vivid that I just had to say something about it.
It's a compound called betaine that causes the red colour, and the presence of betaine is a great reason to eat beetroot. Let's take a look at why.
Have you heard of methylation? It's a key biological process that is going on all the time in our body. It's involved in detoxification, processing hormones, turning genes on and off, building neurotransmitters and much more. In other words, it's a key process for health.
How does this relate to betaine? Betaine is a nutrient that can keep the methylation cycle "turning". Ensuring enough nutrient availability for methylation is important in relation to cardiovascular disease, cancer risk, mental health and hormonal health, amongst others. I know I have genetic variants that mean that I benefit from a higher than average intake of betaine. Other sources of betaine include spinach and quinoa.
Another great reason to eat beets is because they contain nitrates. These are converted into nitric oxide, which dilates blood vessels. Drinking a glass of beetroot juice daily results in significant reductions in systolic blood pressure in people with hypertension.
The dilation of blood vessels by the nitrates results in improved oxygenation throughout the body, so it shouldn't be too surprising to learn that taking beetroot before an event (as powder or juice if the whole food is difficult) can improve athletic performance and stamina.
Beetroot is also a great source of nutrients such as fibre, folate, potassium, manganese and vitamin C. However, as betaine is harder to come by in the diet, it's the betaine that keeps me eating beets.
When I was young, we never ate beetroot at home. My mum used to say it was the only food she wouldn't eat. I wonder now if she had only ever tasted soggy pickled beetroot. I prefer to buy fresh beetroot and then slice it thinly into a salad, chop it into chunks and roast it, or again slice it finely and mix it into patties. And sometimes I juice it and drink it before exercising - just in case it might help me beat some records 😉!
