Potatoes could send your blood pressure through the roof

Ah, potatoes. They somehow found their way into nearly every meal – whether it’s in the form of fries, or baked, scalloped, or mashed.

But potatoes have something of an identity crisis. They’re considered a vegetable, but they’re made up almost entirely of starch. So they act less like a veggie and more like a bowl of pasta.

So despite their healthy “vegetable” distinction, don’t be fooled. It’s a wolf in sheep’s clothing… and the latest research shows how it can derail your otherwise healthy diet.

A new study published in the British Medical Journal confirms that whether you boil, bake, mash or fry your spuds, eating these so-called veggies increases your risk for developing high blood pressure.

As I’ve previously shared with you, the humble potato can increase your risk of type 2 diabetes and expand your waistline. And now, this new study says that potatoes can also send your blood pressure through the roof.

Researchers from Harvard Med School and Brigham and Women’s Hospital used three large cohort studies to follow 187,000 men and women for more than 20 years.

They found that people who consumed four or more servings of potatoes a week over a prolonged period of time – especially women – had a significantly increased risk for high blood pressure when compared to those who ate less than one serving a month.

Fries were the worst offenders, increasing the risk by 17 per cent… but even potatoes cooked in a “healthy” way (like baked or boiled) increased the risk for high blood pressure by 11 per cent.

The researchers suggest that the high glycaemic load in potatoes can contribute to high blood pressure not only because of weight gain, but also an increase in oxidative stress and inflammation. And it may be enough to negate the potential health benefits of the potassium content in potatoes.

According to the study, if you replace just one of your servings of potatoes for the week with a non-starchy vegetable like broccoli, you’re more likely to keep your blood pressure in check.

But if you ask me, you’re better off following the Paleo diet and skipping starches altogether. And, vegetable or not, white potatoes are NOT considered Paleo.

You can substitute your mashed potatoes with mashed cauliflower, a cruciferous cousin of broccoli that’s packed with cancer-fighting sulphoraphane and none of the starch found in potatoes. A cup of cauliflower has fewer carbohydrates and about a tenth of the calories of a potato.

If you REALLY need your potato fix, try swapping white potatoes for Paleo-friendly sweet potatoes. The tasty sweet potato is filled with potassium like the white potato… but it
also has heart-healthy magnesium… and it’s been shown to actually LOWER blood pressure.
