Beetroot has been in the news for all the wrong reasons. Supply issues in recent months have seen a shortage of tinned beetroot on Australian supermarket shelves. At one point, a tin was reportedly selling on eBay for more than A$65.

But as supplies increase, we turn our attention to beetroot’s apparent health benefits.

Is beetroot really vegetable Viagra, as UK TV doctor Michael Mosley suggests? What about beetroot’s other apparent health benefits – from reducing your blood pressure to improving your daily workout? Here’s what the science says.

What’s so special about beetroot?

Beetroot – alongside foods such as berries, nuts and leafy greens – is a “superfood”. It contains above-average levels per gram of certain vitamins and minerals.

Beetroot is particularly rich in vitamin B and C, minerals, fibre and antioxidants.

Most cooking methods don’t significantly alter its antioxidant levels. Pressure cooking does, however, lower levels of carotenoid (a type of antioxidant) compared to raw beetroot.

Processing into capsules, powders, chips or juice may affect beetroot’s ability to act as an antioxidant. However, this can vary between products, including between different brands of beetroot juice.

Is beetroot really vegetable Viagra?

The Romans are said to have used beetroot and its juice as an aphrodisiac.

But there’s limited scientific evidence to say beetroot improves your sex life. This does not mean it doesn’t. Rather, the vast number of scientific studies looking at the effect of beetroot have not measured libido or other aspects of sexual health.

How could it work?

When we eat beetroot, chemical reactions involving bacteria and enzymes transform the nitrate in beetroot into nitrite, then to nitric oxide. Nitric oxide helps dilate (widen) blood vessels, potentially improving circulation.

The richest sources of dietary nitric oxide that have been tested in clinical studies are beetroot, rocket and spinach.

Nitric oxide is also thought to support testosterone in its role in controlling blood flow before and during sex in men.

Beetroot’s ability to improve blood flow can benefit the circulatory system of the heart and blood vessels. This may positively impact sexual function, theoretically in men and women.

Therefore, it is reasonable to suggest there could be a modest link between beetroot and preparedness for sex, but don’t expect it to transform your sex life.

What else could it do?

Beetroot has received increasing attention over recent years due to its antioxidant and anti-tumour effect in humans.

Clinical trials have not verified all beetroot’s active ingredients and their effects. However, beetroot may be a potentially helpful treatment for various health issues related to oxidative stress and inflammation, such as cancer and diabetes. The idea is that you can take beetroot supplements or eat extra beetroot alongside your regular medicines (rather than replace them).

There is evidence beetroot juice can help lower systolic blood pressure (the first number in your blood pressure reading) by 2.73-4.81 mmHg (millimetres of mercury, the standard unit of measuring blood pressure) in people with high blood pressure. Some researchers say this reduction is comparable to the effects seen with certain medications and dietary interventions.

Other research finds even people without high blood pressure (but at risk of it) could benefit.

Beetroot may also improve athletic performance. Some studies show small benefits for endurance athletes (who run, swim or cycle long distances). These studies looked at various forms of the food, such as beetroot juice as well as beetroot-based supplements.

How to get more beetroot in your diet

There is scientific evidence to support positive impacts of consuming beetroot in whole, juice and supplement forms. So even if you can’t get hold of tinned beetroot, there are plenty of other ways you can get more beetroot into your diet. You can try:

• raw beetroot – grate raw beetroot and add it to salads or coleslaw, or slice beetroot to use as a crunchy topping for sandwiches or wraps
• cooked beetroot – roast beetroot with olive oil, salt and pepper for a flavour packed side dish. Alternatively, steam beetroot and serve it as a standalone dish or mixed into other dishes
• beetroot juice – make fresh beetroot juice using a juicer. You can combine it with other fruits and vegetables for added flavour. You can also blend raw or cooked beetroot with water and strain to make a juice
• smoothies – add beetroot to your favourite smoothie. It pairs well with fruits such as berries, apples and oranges
• soups – use beetroot in soups for both flavour and colour. Borscht is a classic beetroot soup, but you can also experiment with other recipes
• pickled beetroot – make pickled beetroot at home, or buy it from the supermarket. This can be a tasty addition to salads or sandwiches
• beetroot hummus – blend cooked beetroot into your homemade hummus for a vibrant and nutritious dip. You can also buy beetroot hummus from the supermarket
• grilled beetroot – slice beetroot and grill it for a smoky flavour
• beetroot chips – slice raw beetroot thinly, toss the slices with olive oil and your favourite seasonings, then bake or dehydrate them to make crispy beetroot chips
• cakes and baked goods – add grated beetroot to muffins, cakes, or brownies for a moist and colourful twist.

Are there any downsides?

Compared to the large number of studies on the beneficial effects of beetroot, there is very little evidence of negative side effects.

If you eat large amounts of beetroot, your urine may turn red or purple (called beeturia). But this is generally harmless.

There have been reports in some countries of beetroot-based dietary supplements contaminated with harmful substances, yet we have not seen this reported in Australia.

What’s the take-home message?

Beetroot may give some modest boost to sex for men and women, likely by helping your circulation. But it’s unlikely to transform your sex life or act as vegetable Viagra. We know there are many contributing factors to sexual wellbeing. Diet is only one.

As a clinical psychologist, I often have clients say they are having trouble with thoughts “on a loop” in their head, which they find difficult to manage.

While rumination and overthinking are often considered the same thing, they are slightly different (though linked). Rumination is having thoughts on repeat in our minds. This can lead to overthinking – analysing those thoughts without finding solutions or solving the problem.

It’s like a vinyl record playing the same part of the song over and over. With a record, this is usually because of a scratch. Why we overthink is a little more complicated.

We’re on the lookout for threats

Our brains are hardwired to look for threats, to make a plan to address those threats and keep us safe. Those perceived threats may be based on past experiences, or may be the “what ifs” we imagine could happen in the future.

Our “what ifs” are usually negative outcomes. These are what we call “hot thoughts” – they bring up a lot of emotion (particularly sadness, worry or anger), which means we can easily get stuck on those thoughts and keep going over them.

However, because they are about things that have either already happened or might happen in the future (but are not happening now), we cannot fix the problem, so we keep going over the same thoughts.

Who overthinks?

Most people find themselves in situations at one time or another when they overthink.

Some people are more likely to ruminate. People who have had prior challenges or experienced trauma may have come to expect threats and look for them more than people who have not had adversities.

Deep thinkers, people who are prone to anxiety or low mood, and those who are sensitive or feel emotions deeply are also more likely to ruminate and overthink.

Also, when we are stressed, our emotions tend to be stronger and last longer, and our thoughts can be less accurate, which means we can get stuck on thoughts more than we would usually.

Being run down or physically unwell can also mean our thoughts are harder to tackle and manage.

Acknowledge your feelings

When thoughts go on repeat, it is helpful to use both emotion-focused and problem-focused strategies.

Being emotion-focused means figuring out how we feel about something and addressing those feelings. For example, we might feel regret, anger or sadness about something that has happened, or worry about something that might happen.

Acknowledging those emotions, using self-care techniques and accessing social support to talk about and manage your feelings will be helpful.

The second part is being problem-focused. Looking at what you would do differently (if the thoughts are about something from your past) and making a plan for dealing with future possibilities your thoughts are raising.

But it is difficult to plan for all eventualities, so this strategy has limited usefulness.

What is more helpful is to make a plan for one or two of the more likely possibilities and accept there may be things that happen you haven’t thought of.

Think about why these thoughts are showing up

Our feelings and experiences are information; it is important to ask what this information is telling you and why these thoughts are showing up now.

For example, university has just started again. Parents of high school leavers might be lying awake at night (which is when rumination and overthinking is common) worrying about their young person.

Knowing how you would respond to some more likely possibilities (such as they will need money, they might be lonely or homesick) might be helpful.

But overthinking is also a sign of a new stage in both your lives, and needing to accept less control over your child’s choices and lives, while wanting the best for them. Recognising this means you can also talk about those feelings with others.

Let the thoughts go

A useful way to manage rumination or overthinking is “change, accept, and let go”.

Challenge and change aspects of your thoughts where you can. For example, the chance that your young person will run out of money and have no food and starve (overthinking tends to lead to your brain coming up with catastrophic outcomes!) is not likely.

You could plan to check in with your child regularly about how they are coping financially and encourage them to access budgeting support from university services.

Your thoughts are just ideas. They are not necessarily true or accurate, but when we overthink and have them on repeat, they can start to feel true because they become familiar. Coming up with a more realistic thought can help stop the loop of the unhelpful thought.

Accepting your emotions and finding ways to manage those (good self-care, social support, communication with those close to you) will also be helpful. As will accepting that life inevitably involves a lack of complete control over outcomes and possibilities life may throw at us. What we do have control over is our reactions and behaviours.

Remember, you have a 100% success rate of getting through challenges up until this point. You might have wanted to do things differently (and can plan to do that) but nevertheless, you coped and got through.

So, the last part is letting go of the need to know exactly how things will turn out, and believing in your ability (and sometimes others’) to cope.

What else can you do?

A stressed out and tired brain will be more likely to overthink, leading to more stress and creating a cycle that can affect your wellbeing.

So it’s important to manage your stress levels by eating and sleeping well, moving your body, doing things you enjoy, seeing people you care about, and doing things that fuel your soul and spirit.

Distraction – with pleasurable activities and people who bring you joy – can also get your thoughts off repeat.

If you do find overthinking is affecting your life, and your levels of anxiety are rising or your mood is dropping (your sleep, appetite and enjoyment of life and people is being negatively affected), it might be time to talk to someone and get some strategies to manage.

When things become too difficult to manage yourself (or with the help of those close to you), a therapist can provide tools that have been proven to be helpful. Some helpful tools to manage worry and your thoughts can also be found here.

When you find yourself overthinking, think about why you are having “hot thoughts”, acknowledge your feelings and do some future-focused problem solving. But also accept life can be unpredictable and focus on having faith in your ability to cope.
