7 Win-Win Plant-Powered Solutions To Global Hunger That Benefit Human Health and The Planet

Hello friends! Popping in after a hectic week to share a more formal piece about fighting global hunger with sustainable solutions. This is a mash up of my two academic passions: environmental health science and nutrition.  have an extended version I may share later with much greater detail. For now, hope you enjoy the following!

7 Win-Win Plant-Powered Solutions To Global Hunger That Benefit Human Health and The Planet


Despite producing more than enough calories per capita needed to feed each person on earth, a stunning 830 million people have insufficient access to food, and many suffer from malnutrition-related conditions, including stunting, wasting, and micronutrient deficiencies. Meanwhile, obesity and chronic diet-related diseases such as diabetes and cardiovascular disease present an additional concern, creating the ‘dual burden of malnutrition.’

While finding hunger solutions, we must also consider the urgent threat of global climate change. The problem is complex, as the food system is both a leading cause of anthropometric climate change, and an industry deeply impacted by its effects.

Ameliorating these problems simultaneously is an onerous task. Luckily, there are many ways to build a healthy and sustainable diet, and many innovations at our fingertips that can help get us there. The following “win-win” plant-powered solutions benefit both human health and the environment, and have use across a variety of contexts. If applied on a global scale, these innovations could help lead a path towards a healthful, sustainable,  food systems future.

1.Win-Win: Swapping protein


It is well-known that meat, particularly livestock meats have some of the largest carbon and water footprints of all foods, representing 14.5% of all global greenhouse gas emissions (GHG). Red and processed meats have also been associated with increased risks of cancer and cardiovascular disease. But there are other ways to consume protein. Plant-based proteins including legumes, nuts and whole grains are far less carbon and water-intensive than animal proteins, and offer numerous health benefits, including lower rates of diabetes, cardiovascular disease, and cancer. A paradigm shift from meat to lesser-processed plant proteins will remain important moving forward.

2. Win-Win: Focusing on whole plant foods


Fruits, vegetables, legumes, nuts, seeds, and whole grains are all micronutrient-dense foods, filled with powerful plant compounds, including cancer-quenching flavonoids and heart-friendly plant sterols. Their high levels of dietary fiber provide satiety while lowering risks of developing various chronic diseases, such as stroke, hypertension, and diabetes. Fruits and vegetables vary in their water and carbon use, but are generally far less detrimental to the environment than animal-based foods, especially when carefully planned according to optimal growing seasons, and delivered to consumers at a local level, whenever possible.

3.Win-Win: Algae as food


Although algae has been consumed as part of the human diet for thousands of years, large scale adoption of algae as food has not yet fully taken off. However, it should. Algae offers a potential sustainable source protein and vitamin B-12, an essential micronutrient primarily found in animal-based foods, offering a valuable source of nutrition for those shifting towards a sustainable plant-based diet. Algae could also be considered as an alternative to seafood as a source of DHA and EPA, while helping decrease the current harm caused to the oceans by overfishing. The humble plant also boasts a substantial amount of iodine, a mineral that ranks among the leading micronutrient deficiencies in the world. Scaling up nori (dried green and purple laver) and red algae production is worth considering for planetary and human health.

4. Win-Win: Biotechnology


Biotechnology (such as the use of genetically modified organisms) is a powerful tool that may offer solutions to various malnutrition-related problems. For example, biotechnology can be used to address many micronutrient deficiencies of public health concern, including Vitamin A, iodine, iron,and zinc, all of which have already been implemented into staple crops such as rice and proved efficacious in alleviating rates of deficiencies. Furthermore, biotechnology has helped create more sustainable and resilient crops better equipped to deal with the increasingly temperamental climate shifts, dwindling water supplies, and extreme weather events, and offers potential to decrease reliance on harmful pesticides.

5. Win-Win: Hydroponics and fortification

Hydroponic farming (also known as ‘vertical farming’) allows for cultivation of large amounts of plant-foods, and is uniquely adaptable in urban settings, thereby slashing fresh food mileage and emissions in areas of high demand but little agricultural landscape. In addition to its high productivity and efficient water usage, hydrophobic farming offers opportunities for plant-food fortification, offering an additional way to combat micronutrient deficiencies and encourage fresh, plant-based food consumption at a larger, less resource-intensive scale.

6. Win-win: Replacing sugar crops with more diverse plant crops


Consumption of added sugar is associated with increased rates of obesity, diabetes, and dental caries, and offer little nutritive value besides caloric density. High-fructose corn syrup (HFCS), often found in soft drinks and packaged foods, is also associated with elevated risks of cardiovascular disease. Presently, sugar and HFCS-laden products are cheap, highly accessible, and supported by subsidies and tariffs. As a result, much land is devoted to corn production, thereby limiting land available for other crops and threatening agricultural diversity. Ending sugar subsidies and replacing them with other fruit and vegetable subsidies could benefit not only human health, but also encourage crop diversity, thus expanding the variety of plants we grow and consume, which is important for long-term agriculture and dietary well-being.

7. Win-Win: Widespread use of low-water, highly nutritious fruit crops

There are many low-resource, weather-resistant, food-bearing plants that are presently not widely used. For example, the moringa oleifera is a fast-growing, drought-resistant tree native to tropical South Asia. It produces high volumes of nutritious fruits and edible leaves, and its kernels can be used to produce oil. Artocarpus altilis (‘breadfruit’), is another hearty, fast-growing species of flowering tree that produces edible fruits rich in protein, vitamins and minerals, and requires few fertilizer and pesticides. While these plants and others like them are already used in some areas to alleviate malnutrition, more widespread cultivation of their bounty is worthy of exploring.


Solving global hunger in a sustainable way will be a real challenge. However, starting with little “win-win” solutions can help guide a path forward to create a more sustainable, nutritious future for all. From algae to breadfruit to biotechnology, focusing on expanding innovations and taking full advantage of the power of plants can lead to improved planetary and human health moving forward.
