The Healing Properties of Turmeric: Could Curcumin Play a Role in Cancer Prevention

 

It seems that not only is Curcumin a powerful anti-inflammatory, it may play a role in protecting us against cancer.

The study of plant-derived substances has evolved in the last 200 years, after the discovery that different active compounds can be derived from plants and studied for their health benefits. One such compound that has gained a lot of attention is the polyphenol curcumin, which is present in the yellow-orange turmeric spice powder.

Curcumin was first isolated in 1815 by two scientists from Harvard College Laboratory. Since then, it has been studied extensively for its powerful antioxidant, anti-inflammatory, anti-microbial and antiviral activities. In particular, it was found that curcumin could influence a wide range of molecules that play a role in cancer, and this unsurprisingly sparked a new area of interest among researchers – the study of curcumin and its anti-cancer potential.

Since 1987, the National Cancer Institute has tested over 1000 different agents for their potential chemopreventative activities (meaning the ability to reduce the risk of, or delay the development of cancer). Only about 40 of those ever moved to clinical trials, with one of those being curcumin.

Chemopreventative agents are usually grouped into three different subgroups:

  1. Antiproliferatives (substances used to prevent or slow cell growth, particularly malignant cells, into surrounding tissues)
  2. Antioxidants (compounds that protect your cells from the damaging effects of free radicals)
  3. Carcinogen-blocking agents (agents that disrupt the mechanisms that drive carcinogenesis, such as DNA damage)

As identified by researchers in a 2013 review, curcumin is found to belong to all three of these subgroups, and appears to play a role in helping to slow and/or block every stage of cancer, findings which help shed light on the potential powerful anticancer capabilities of curcumin.

Back in 1987 an interesting study examined the effects of curcumin on the DNA mutating ability of several toxins, and found that it was a successful anti-mutagen (an agent that helps to prevent the mutations of a compound) against several environmental carcinogens (however this was conducted in test tubes, not on humans).

Following on from this, a 1992 study was conducted studying the effects of eating less than 1 tsp of turmeric every day for a month, on a group of non-smokers vs smokers. After the month was over, the smoker group saw significant decreases in DNA mutagens in their urine (however it still exceeded that of the non-smoker group, so it’s better not to smoke at all).

There have been many more studies and systematic reviews conducted since then, focusing on the potential health benefits of dietary turmeric, with findings showing the inhibition of cell growth in many types of cancerous cells, shedding light on curcumin as an anti-mutagen and its potential usefulness in chemoprevention.  There’s certainly a lot of exciting research out there in the world of “food as medicine”.

Tumeric has many other benefits and properties, particulary acting as an anti-inflammatory agent.  We love using it in our meals and our vegan protein powder blends.

Turmeric can be purchased in powder form from the spice aisle of the supermarket, or as fresh turmeric root (looks a little like ginger root), which is also usually available from most grocery stores in the fresh produce section.  For enhanced bio-availability use pepper with turmeric.

Do you have turmeric in your spice cabinet? If so, how do you like to use it?

5 Easy and Versatile Veggies to Grow in Your Own Home Garden

 

Crisp, sweet carrots, snapping peas out of their shells, pulling firm, dark red beets out of the garden…growing your own veggies is not only fun and relaxing, but it’s also an amazing way to diversify and supercharge your diet with wholesome nutrition, stay active and get some vitamin D. No wonder why gardening is considered a natural stress reliever!

Although the thought of growing your own veggies can be overwhelming, there are some veggies that are super easy to grow, as well as being productive as crops, versatile to use, healthy to eat and great tasting! Plus, you’re more likely to eat more vegetables if they are easily accessible to you, and it’s really fun to share and cook with healthy food that has been nurtured by your own efforts! 

Here are 5 top picks for the best veggies to grow at home:

1. LETTUCE – Lettuce is super easy to grow (and actually quite hard to get rid of!), high in nutrients, low in calories and really hydrating, due to its high water content. Lettuce is one of those foods that you don’t notice in a dish until it’s not there, like in an egg and lettuce sandwich, or shredded lettuce in tacos. Lettuce seems to just make a dish 10 times better.

2. CARROTS – Carrots have a huge temperature growing range which means they can be grown in many climates all year round. They’re also really productive and can be producing for months after you plant them. Being quite a dense vegetable, even just a few standard size ones or small varieties are enough to feed the whole family for dinner. There’s a reason why people promote carrots for better eye sight – carrots contain the antioxidants lutein and beta carotene which are known for their eye health benefits!

3. CABBAGE – Cabbages are such a diverse veggie, they can be preserved and pickled to have in salads or sandwiches, made into slaw, or added into stir-fries for a crunchy element. They’re also really good for you. A study conducted in Western Australia with 900 women over the age of 70 found that eating three or more portions of veggies per day (a combination of cabbage, broccoli, cauliflower and Brussel sprouts) lowered the participants risk of heart disease and stroke. Mini cabbages are quick to grow from seed and harvest and can go a long way in a delicious preserve such as sauerkraut.

4. BEETS – A known “superfood”, beets are packed with vitamins and minerals, high in fibre, low in fat and low in calories. They’re also super easy to grow and you can even eat the tops of the beets – the beet leaves, which are just a regular leafy vegetable. This makes them a really versatile and productive option to grow in your home garden.

5. ONIONS – There have been heaps of scientific studies looking into the health benefits of onions, with findings showing benefits with regulating blood sugar, inhibiting the growth of harmful bacteria in your gut, boosting the immune system and the list goes on! Onions are a pretty hearty crop to grow, with varieties to suit all climates. If you’re short on space, try growing some spring onions, which can grow just about anywhere.

TOP TIP: No space for a home garden? Regrow the spring onions you buy from the supermarket by placing the white stems in a glass of water. Place the glass near a sunny window and wait for the magic to happen!

The Importance of Eating Antioxidants with Every Meal

 

 

Firstly, what are antioxidants?

Antioxidants are compounds found in certain foods that help to neutralise the free radicals (damaging molecules produced through the body’s process of oxidation) in your blood. In short, they help to protect our cells and DNA from damage that can lead to disease. That’s why it’s really important that we take in more antioxidants than we use up. In fact, the very act of eating increases oxidative stress, which is the attack on your cells from free radicals.

Antioxidants originate from the plant kingdom, due to the thousands of antioxidant compounds found naturally in fruits and vegetables. Ideally, fresh produce should be sneaking its way into every meal that we eat. But, we know that that’s not always possible – takeaway nights, dining out, dinner at a friend’s house…sometimes it’s a little hard to eat healthy all the time.

A few interesting studies have shed a light on antioxidants and their ability to counteract the negative oxidative effects of an “unhealthy” meal e.g. a meal that is high in fat, sugar and refined carbohydrates, and low in whole foods.

A 2010 review found that consuming fruits which are high in phenolic phytonutrients (health-promoting compounds) with an unhealthy meal (high fat, pro-inflammatory, low in nutrients) increases the antioxidant capacity of the blood and helps to counterbalance some of the negative effects of the meal.

In another interesting study, participants were given standard breakfast items which caused a high increase in oxidized cholesterol in their blood stream 6 hours after the meal. However, adding a cup of antioxidant-rich strawberries to the meal kept the meal from contributing to further oxidation, and allowed them to eat lunch at a baseline oxidation level.

A similar study found that eating a bunch of grapes with a meal resulted in a rise in blood antioxidant levels, leaving the body in a positive antioxidant balance for a few hours. The same results were found with blueberries.

These findings highlight the importance of eating antioxidants with every meal, and if you can’t avoid an unhealthy meal, adding a side of berries or grapes to your plate may be beneficial in helping to maintain oxidative balance.

A 2004 study found that out of all fruits, berries (e.g. strawberries, blueberries) were the best source of polyphenol antioxidants.

Berries are on the dirty dozen, so organic berries are best. Keeping frozen berries on hand is also a great idea, and actually, frozen berries often have more antioxidants and other nutrients because they’re frozen shortly after picking. Essentially, frozen produce is often even fresher than what we call “fresh produce”!

10 Signs You Need to Detox!

 

You may not realise it, but every day we are exposed to different toxins and pollutants, all products of the modernized world we now live in. From pollutants in our air, water and soil, to synthetic chemicals, heavy metals, heavily processed foods and food additives.

Normally, the body does an amazing job at facilitating toxin elimination to help keep us healthy and thriving. Each system in our body is involved in a complex process named “detoxification”, involving highly sophisticated mechanisms for the removal of toxins and unwanted substances from the body.

However, if the body’s natural detoxification process is compromised (for example, due to stress, or an overworked liver from a high intake of processed foods, refined sugars, alcohol, smoking or the exposure to too many environmental toxins), this causes significant consequences on our health.

Our liver, or otherwise our “detox manager” has the busy job of filtering out toxins from the foods we eat and the things we are exposed to in our environment. When our liver gets overloaded (just like for example, if you get overworked in your job), it starts to have trouble processing the toxins efficiently and fast enough. This causes toxins to build-up in the body, which causes inflammation, and this creates a vicious cycle which is difficult to break.

The build-up of toxins in the body is linked to autoimmune conditions, gastrointestinal disorders, inflammation, fibromyalgia, chronic fatigue syndrome and numerous other illnesses and diseases.

Here are 10 signs that you may need to detox:

  1. Persisting fatigue
  2. Unexplainable weight gain
  3. Brain fog
  4. Headaches
  5. Stubborn belly fat
  6. Skin problems (acne, rashes)
  7. Achy muscles and joints
  8. Digestive distress (bloating, gas, diarrhoea)
  9. Irregular sleep patterns
  10. Feeling anxious or depressed

We don’t believe in detoxes that are aimed to starve you or drive you insane. That’s why we created our 4-week Wholesomeness Detox, specially put together by our nutritionist and cooked by our qualified chef’s.

Probiotics and the Link with Brain Health

 

The beneficial live microorganisms that are present in some fermented foods are called “probiotics” (derived from the Greek word meaning “for life”, and for good reason).

Probiotics have long been studied for the beneficial health effects they produce when consumed. For example, probiotics have been linked to the prevention of colon cancer, cholesterol and blood pressure management, immune function improvements, the prevention of infections, reducing inflammation, and supporting gut health while under stress.

In recent years, a growing body of evidence has also been investigating whether probiotics have the potential to promote a different aspect of health – namely brain health.

The interest in the field of probiotics and mental health was first sparked when a ground-breaking study was conducted in Japan in 2004. When two groups of mice (one group being germ-free, without bacteria in their guts) were placed under stress, the researchers were able to reverse the exaggerated stress response of the germ-free mice by introducing beneficial bacteria into their guts. The experiment highlighted the connection between microbes in the gut and stress responses in the brain, and suggested that altering the gut microbiome (e.g. with probiotics), could influence brain function.

Since then, many studies have focussed on the positive connection between probiotics and brain health, particularly on mood, behaviour and depressive symptoms. 

A recent 2019 large-population based study found an association between probiotic food consumption and lower rates of depression among men. These findings were in line with previous conclusions by Benton et al. who found that probiotics improved mood in healthy individuals who reported having poor mood at the beginning of the experiment.

When our gut is healthy and balanced, our “good” bacteria can do what they’re supposed to do, like produce critical neurotransmitters that effect the biochemistry of our brain, and thus effect mood, behaviour and depression.

These findings reiterate the significant role that diet and nutrition have on regulating and promoting mental health.

Boost your good bacteria for a healthy brain with some of our probiotic-rich dishes:

  • Our Herbed Pine nut & Goji Quinoa Salad, with Beetroot Hummus, Broad beans and Sauerkraut (containing sauerkraut for immune-boosting probiotic benefits)
  • Our Miso Salmon with Asian Vegetables and Brown Rice (containing miso paste, another non-dairy probiotic that we love)
