Research conducted by Roy Morgan found that the vegetarian trend has been growing year on year. About 2.5 million people (12.2 per cent of the population) in Australia are now eating completely, or almost completely, vegetarian.
The 2018 data shows continued growth in people choosing kinder, more sustainable meals. But while many choose to cut out meat for moral and environmental reasons, some are turning towards a veg-based diet to bolster their health.
It’s not actually necessary to eat meat to get all the nutrients needed for good health, and because vegetarians tend to eat more plant-based foods, they often enjoy a diet lower in calories, saturated fat and cholesterol.
It may also be assumed that vegetarians and vegans don’t get enough protein, (which is abundant in meat). However, plant protein can adequately meet or even exceed recommended protein intake, through eating whole grains and legumes, plus foods including lentils, nuts, seeds, dairy and eggs.
That being said, it can be easy to eat a vegie diet of junk food, like pizza, chips and snacks, so vegetarians need to be careful they get all the nutrients the body needs, particularly B12, calcium, iron and zinc.
Lynne Elliot, chief executive of the Vegetarian Society, suggests anyone who is thinking of going vegie should follow a balanced diet, with five portions of fruit and veg a day, plenty of complex carbohydrates and antioxidants, as well as lower saturated fat and cholesterol.
“A vegetarian diet can be a refreshing change,” she hastens to add, so even if you aren’t thinking of cutting out meat full-time, cutting back or having ‘meat-free’ days can totally liven up your cooking repertoire (and you might even save some money in the process).
With that in mind, let’s explore some of the scientific benefits of adopting a vegetarian lifestyle.
1. Reduced type 2 diabetes risk
Studies have shown that vegetarians are less likely than meat eaters to suffer from a number of diseases. According to a study by the University of Navarra in Spain, vegetarians tend to have a lower type 2 diabetes risk, because they’re less likely to be obese, and often have a lower average body mass index (BMI) than meat-eaters.
2. It’s good for your heart
Being vegetarian could also have heart health benefits. A 2013 Oxford University study looked at 45,000 people and compared rates of heart disease between vegetarians and non-vegetarians. It found that a vegie diet can reduce the risk of heart disease by nearly a third (32 per cent), concluding that it was likely down to the diet’s effect on lowering cholesterol and blood pressure.
3. It could lower your cancer risk
The World Cancer Research Fund describes eating red or processed meats (such as sausages or bacon) as a ‘convincing’ risk for colon cancer. Separately, a 2015 US study of 77,000 people found that a vegetarian diet cut the risk of colorectal cancer by 20 per cent.
4. Lower saturated fat consumption
Cutting out meat can markedly reduce fat intake, especially saturated fat – which has been linked to clogged arteries and coronary heart disease. Even extra-lean minced beef has more than four times the fat of pulses such as beans, lentils and peas, and making a Bolognese or curry with Quorn meat or soya mince, for example, can reduce fat by three-quarters.
5. Lower cholesterol and blood pressure
A study by the Vegetarian Society claims that a balanced vegetarian diet contains up to twice as much fibre as the national average diet, and soluble fibre can help to keep cholesterol under control. Soya foods and nuts have been shown to be especially helpful in keeping cholesterol levels low.
6. Longer life expectancy
Research suggests vegetarians may live longer than carnivores. A 2013 US study of more than 73,000 people found a vegetarian diet is associated with a 12 per cent reduction in all-cause mortality, and some reductions in death from specific diseases. A 2003 study of 1.5 million people also found that following a vegetarian diet, or a diet very low in meat, for at least 20 years, can increase life expectancy by 3.6 years.
7. Better skin
Balanced vegie diets can also come with external benefits, packing in lots of vitamins, minerals, and antioxidants that support healthy hair, skin and nails. Chomping on carotenoid-packed vegetables – those with a dark green, red and orange hue – are great for preventing UV light damage, which can lead to melanoma, wrinkles and dry skin.
