The Secret Usefulness of Avocado Pits

A couple of years ago, following the whole avocado toast thing, there was a trend of eating the pit (technically a seed). People would dry them out, chop or blend them into a powder, and treat them basically as a supplement, full of fiber and antioxidants. Now, research indicates that the avocado pit has some other impressive properties.


New research from Penn State found that extract from the avocado pit has significant anti-inflammatory properties. In classic scientist-undersell mode, one of the researchers said, "We saw inhibitory activity at concentrations in the low microgram-per-milliliter range, which is an acceptable amount of activity to justify further studies." In other words, yes, avocado pit extract is anti-inflammatory in a non-nonsense way.

But that doesn't mean that you should try centrifuging your own avocado pit extract. After the trend of blending up the pits, some attention was paid to whether the pit is even edible. Many other seeds, including apple seeds, are not edible, even if you can figure out their texture; apple seeds contain a substance that, in the body, creates cyanide. Not at lethal doses from one apple, sure, but, you know. Cyanide.

The research on avocado pits is far less settled than for apple seeds. The California Avocado Commission, which has every motivation to promote edible avocado pits, says that they do not recommend eating them, as the research has not yet adequately decided whether the pits are safe to eat. Other nutritionists agree.

But the Penn State research furthers the idea that there's something to the pit besides a method to keep guacamole green, or a fun planting experiment. The pits are usually garbage, and while they're highly biodegradable, there still might be a way to make use of them.

It is far too easy to view scarcity and poor quality of water as issues solely affecting emerging economies. While the images of women and children fetching water in Africa and a lack of access to water in India are deeply disturbing, this is not the complete picture.

The city of Flint, Michigan, where dangerous levels of pollutants contaminated the municipal water supply, is a case in point — as is, more recently, the city of Newark, New Jersey.

The Past is No Longer a Guide to the Future

We get ever closer to "day zeros" — the point at when municipal water supplies are switched off — and tragedies such as Flint. These are not isolated stories. Instead they are becoming routine, and the public sector and civil society are scrambling to address them. We are seeing "day zeros" in South Africa, India, Australia and elsewhere, and we are now detecting lead contamination in drinking water in cities across the U.S.

"Day zero" is the result of water planning by looking in the rear-view mirror. The past is no longer a guide to the future; water demand has outstripped supplies because we are tied to business-as-usual planning practices and water prices, and this goes hand-in-hand with the inability of the public sector to factor the impacts of climate change into long-term water planning. Lead in drinking water is the result of lead pipe service lines that have not been replaced and in many cases only recently identified by utilities, governments and customers. An estimated 22 million people in the US are potentially using lead water service lines. This aging infrastructure won't repair or replace itself.

One of the most troubling aspects of the global water crisis is that those least able to afford access to water are also the ones who pay a disproportionately high percentage of their income for it. A report by WaterAid revealed that a standard water bill in developed countries is as little as 0.1 percent of the income of someone earning the minimum wage, while in a country like Madagascar a person reliant on a tanker truck for their water supply would spend as much as 45 percent of their daily income on water to get just the recommended daily minimum supply. In Mozambique, families relying on black-market vendors will spend up to 100 times as much on water as those reached by government-subsidized water supplies.

Finally, we need to understand that the discussion of a projected gap between supply and demand is misleading. There is no gap, only poor choices around allocation. The wealthy will have access to water, and the poor will pay more for water of questionable quality. From Flint residents using bottled water and paying high water utility rates, to the poor in South Africa waiting in line for their allocation of water — inequity is everywhere.

Water Inequity Requires Global Action — Now.

These troubling scenarios beg the obvious question: What to do? We do know that ongoing reports on the 'water crisis' are not going to catalyze action to address water scarcity, poor quality, access and affordability. Ensuring the human right to water feels distant at times.

We need to mobilize an ecosystem of stakeholders to be fully engaged in developing and scaling solutions. The public sector, private sector, NGOs, entrepreneurs, investors, academics and civil society must all be engaged in solving water scarcity and quality problems. Each stakeholder brings unique skills, scale and speed of impact (for example, entrepreneurs are fast but lack scale, while conversely the public sector is slow but has scale).

We also urgently need to change how we talk about water. We consistently talk about droughts happening across the globe — but what we are really dealing with is an overallocation of water due to business-as-usual practices and the impacts of climate change.

We need to democratize access to water data and actionable information. Imagine providing anyone with a smartphone the ability to know, on a real-time basis, the quality of their drinking water and actions to secure safe water. Putting this information in the hands of civil society instead or solely relying on centralized regulatory agencies and utilities will change public policies.

It may seem innocuous to flush a Q-tip down the toilet, but those bits of plastic have been washing up on beaches and pose a threat to the birds, turtles and marine life that call those beaches home. The scourge of plastic "nurdles," as they are called, has pushed Scotland to implement a complete ban on the sale and manufacture of plastic-stemmed cotton swabs, as the BBC reported.
