Avocados: more harm than good?

Is the water consumption worth it?

Yes, you might have spent the last 15 minutes perfecting that avo-on-toast picture to let your Instagram followers know  you're #cleaneating. But if I were to tell you that the avocado industry is causing families living nearby to lose their clean water supply, does it still count as clean eating?

A world without avocados everywhere might sound odd now, but when they were first brought to the UK in the 1960's they were not a big hit. Marks and Spencer introduced them as 'Avocado pears' in shops in 1968, but the name caused a lot of confusion. One customer sent in a complaint after stewing the 'pear' and serving it with custard. It wasn't until the 2010's that the fruit (I know, no wonder people got confused) really took off. Now it seems to be in everything- from chocolate mousse to sushi, french fries to soup... you name it, it probably (definitely) exists. There's even a National Avocado Day- July 31st, in case you fancy celebrating.

The hype is understandable. Although calorie-dense due to the high fat content, the fats found in avocado are mainly monounsaturated fats which lower bad cholesterol and help your cells to develop. They also contain almost 20 vitamins and minerals, such as folic acid, vitamin E and vitamin K. Although the creamy texture of an avocado may be off-putting to some considering we normally associate creaminess with dairy, it makes the fruit an amazing alternative for cooking and baking. Check out some great ideas here!

However, one big issue with the production of avocados is their water footprint.  It takes approximately 2,000 litres of water to produce one kilo of avocados. In Petorca, Chile, where many supermarkets source avocados from, this is even higher due to the region being very dry. 1kg of beef takes around 15,500 litres of water to produce and 1kg of pork is around 4,800 litres, so avocados still have a much lower impact environmentally than meat. But compared to other fruit and veg, avocados are thirsty plants. Potatoes only need about 1/8th of the water to produce and tomatoes need around 180 litres (per kg).

Due to the spike in popularity, avocado farmers in Petorca are illegally installing systems to divert river water to irrigate their crops, meaning those living locally don't have access to clean water. It takes 100,000 litres of water per day to grow a hectare of avocado trees, which is the same amount of water that 1000 people use in a day. Instead, locals have to rely on contaminated water brought in by trucks. However, this causes sickness, meaning they either have to buy bottled water or boil the contaminated water.

It's not just the water usage that's a problem however. The ongoing increase in demand for the fruit puts pressure on farmers to find more space to grow them. In Mexican states such as Michoacán, farmers are cutting down pine trees to plant avocado trees. A report published by Mexico's National Institute of Forestry, Farming and Fisheries in 2012 suggested that around 1,700 acres of forest land was lost every year between 2000 and 2010 to make space for avocado farming. In more recent years, this has dramatically increased as the demand for the fruit continues to grow. The Mexican authorities are struggling to keep up with the illegal deforestation occurring because avocado farmers leave some of the original pine trees to hide the smaller avocado trees below so they aren't visible from above.

Personally, the problems avocados cause are enough for me to try my hardest not to eat them. Everything we eat will have some sort of impact on the environment, but the more we educate ourselves, the more we can find the foods that work best for ourselves and our planet. Sometimes, they're in the only veggie option on a menu, so if that happens I'll pick it and enjoy it, knowing it's a treat. After all, we have to eat something, and choosing the meat-free option is still a great choice to make!

Next week- is olive oil killing birds?

Almond milk: more harm than good?

Is your morning coffee costing the lives of billions of bees? There's no denying it- plant-based milk is everywhere. In 2018, there was uproar in the US as a shortage of the popular oat milk brand 'Oatly' broke out, due to sales growing faster than even the company expected.  Demand for cow's milk is falling as people begin to choose alternative milks such as coconut, soya and even pea. However, this isn't without causing some controversy, of course. One plant milk in particular has come under fire recently, due to claims that its production is causing the deaths of billions of honey bees. Now, I'm not saying that we should just give up and switch back to drinking cow's milk. The 2018 University of Oxford study shows that dairy milk produces almost three times more greenhouse gasses than any milk alternative available.   So whichever plant milk you choose, it's still so much better for the environment than dairy. But if you're an almond milk lo...

Lockdown Baking Series: The 5th and final bake- Cinnamon rolls

As lockdown measures start to ease and we begin to return to some form of 'normal' life, it felt right to bring the Lockdown Baking Series to a close. But I wanted to end it on a (sugar) high, and what better way to do that than with cinnamon rolls? For years I've been using the excuse that recipes that use enriched dough (a classic bread dough with ingredients such as butter added) can't be made vegan and be just as good, because they wouldn't have the same richness that dairy and eggs bring. However, when I discovered these cinnamon rolls, I was proven wrong.    I first discovered this recipe when I had a craving for cinnamon rolls during Veganuary, and I haven't looked back since. They're just as soft and light, and even with plant-based margarine, they still taste surprisingly buttery. Now I know that a lot of people think the only suitably topping for cinnamon rolls is cream cheese frosting, which of course makes them more difficult to make vegan. Howev...

Veganism: more harm than good?

As veganism continues to rise in popularity, so does the amount of backlash claiming that going vegan isn't as good for the planet as people think. From avocados to coconuts, foods popular in vegan diets are now claimed to be causing serious harm to the environment. But what really is the truth?  Vegans eat more than just salad, right? So you've seen the news. Climate change is happening, and unless we start to significantly reduce carbon emissions, it's only going to get worse. More and more people are changing their lifestyles to reduce their individual carbon footprint, whether that's ditching flying, cutting down on plastic. One of the biggest ways people are doing their bit for the environment is by reducing meat and dairy intake. A University of Oxford study found that if everybody followed a plant-based diet, greenhouse gas emissions from food production would be reduced by 49%, and there would be a whopping 76% reduction in land use.   Early Bird...
