Micro Solutions For A Macro Problem: How Marine Algae Could Help Feed The World

By  and  via The Conversation

Our planet faces a growing food crisis. According to the United Nations, more than 800 million people are regularly undernourished. By 2050, an additional 2 to 3 billion new guests will join the planetary dinner table.

Meeting this challenge involves not only providing sufficient calories for every person, but also assuring a balanced diet that includes the protein and nutrients that are essential to good health. In a newly published study, we explain how marine microalgae could be a sustainable solution for solving global macro-hunger.

Problems with current food production systems

The current Western diet requires vast amounts of land, water and energy, is heavily polluting and is a major contributor to climate change. Providing nutritious food for an ever-growing global population with increasing per capita demand is pushing our current food production system beyond its limits.

Livestock production is replacing forests with cropland and pastures for meat and animal feed. Nitrogen and phosphorous fertilizer used to grow feed grain and other crops is degrading soils and creating biological dead zones in some 400 estuaries around the world.

Fish are an important source of omega-3 fatty acids and essential amino acids that make up our proteins. However, eating fish has some downsides. They can concentrate heavy metals and toxic organic chemicals in their tissues and pass them on to us. Furthermore, most ocean fisheries are overfished or at maximum production.

Aquaculture is producing a growing share of world seafood. But fish farms can have serious environmental impacts, including water pollution, disease transmission to wild fish and habitat destruction. Demand for small ocean fish to feed those raised on farms is depleting wild stocks.

An alternative approach: Cutting out the ‘middle fish’

In our paper, we propose an alternative solution: commercial production of marine microalgae as a staple human food and feed for animals and farmed fish. These tiny organisms are the ultimate source of omega-3 fatty acids and amino acids that humans need in our diets, and which many of us get by eating fish. But fish are merely aquatic intermediaries in the nutrition business. We can feed the world more efficiently by “cutting out the middle fish.”

Microalgae are a nearly untapped resource, and are found in both freshwater and marine aquatic systems. Although they are only few micrometers in size, they produce amino acids, fatty acids, vitamins, minerals, antioxidants, polymers and carbohydrates.

For example, the omega-3 rich microalgae Nannochloropsis oculata, or simply Nanno, is a promising potential source of high-nutrient food and feed. It is 40 percent protein by dry weight, of which one-third contains essential amino acids, and 6 percent EPA omega-3 essential fatty acid in a highly bioavailable form.

Only a handful of algal species are used commercially now, but hundreds of strains have the potential to become food and feed sources. Microalgae are currently used as a food ingredient, a food supplement and as aquafeed for fish.

Producing Nanno

Microalgae are commercially cultivated using several methods that have a range of sustainability footprints. The first is an aerobically fermented system, where cultivation is performed in dark, mixing vessels using sugar as the main energy source for the algae. Algae may also be cultivated in open ponds, using either fresh- or saltwater, carbon dioxide and sunlight. Alternatively, they may be grown in brackish water or seawater in closed, transparent tubes called photobioreactors.

Nanno is currently being grown at a commercial scale using brackish water in outdoor ponds with added carbon dioxide in Texas, and in photobioreactors using seawater and carbon dioxide at a geothermal power station in Iceland. Here sunlight is replaced by efficient LED lights powered by inexpensive, zero-polluting renewable electricity from the power plant.

Photobioreactors require the least amount of water and fertile land. These reactors are like LEGO blocks that can be stacked vertically. Since it is a closed system, this approach minimizes loss of water through evaporation.

One sustainability metric for comparing protein production from animals, plants and marine algae is the amount of land and water needed to produce an equal quantity of essential amino acids from each type of food. We calculate that producing one kilogram of beef-sourced essential amino acids requires 148,000 liters of freshwater and 125 square meters of fertile land. In contrast, producing the same amount from Nanno raised in an open pond with brackish water requires only 20 liters of freshwater and 1.6 square meters of nonfertile land.

Counterintuitively, some plant protein requires very large amounts of land and water, even relative to some meat sources. For example, peas require about twice as much freshwater and 6.5 times the footprint of fertile land to produce the same amount of essential amino acids as chicken.

Turning microalgae into food products

How does one eat Nanno? Currently it comes as a soft gel capsule of marine microalgae oil, marketed as an alternative to krill or fish oil as a daily source for omega-3’s. In powdered form, whole algae or algae extract could serve as an ingredient in health bars, sports snacks or pasta. Whole algae, such as Spirulina and Chlorella, are already commercially viable and have entered the market, along with other algae-based products such as algal tea and algal flour.

In its current form Nanno can be used as a protein and fatty acid supplement to improve the nutritional level of undernourished people around the world, and as feed for farmed fish and livestock. Most algae-based products are marketed in the United States as dietary supplements, but we believe the time has arrived to introduce algae-based foods to the dining table.

A number of companies already offer innovative alternative meat products, which have the potential to become large-scale food sources with nutritional content and taste comparable to meat. But products based on potatoes, wheat and soy still consume large amounts of freshwater and arable land, with the same environmental disadvantages of current agriculture.

By our calculation, pea- and soy-based alternative meat products with similar nutritional amino acid value to Nanno could be produced using 6.4 times less freshwater than beef, but would require 2.2 times more fertile land. In contrast, using marine microalgae reduces land usage by over 75-fold, since no fertile land is required, and lowers freshwater usage by a factor of 7,400.

Our paper describes a sustainable system for cultivating microalgae that is economically viable. The next step is persuading food scientists to utilize it as the basis for alternative meat products. Chefs and connoisseurs, gastronomes and gourmands, consumers and critics can all help the planet by taking part in a global transition to algae-burgers.

(Natural News)
Over 30 million people – almost 10 percent of the United States population – currently suffer from diabetes, with type 2 diabetes accounting for up to 95 percent of the cases. And, let’s not forget the millions of people in a prediabetic condition – which leads to all sorts of health issues, as well. It almost goes without saying that, as a society, we need help now.

This staggering sum reflects a national epidemic, one which shows no signs of slowing down any time soon. While Western medicine insists there is ‘no known cure’ for diabetes – and offers its failed attempts at managing the disease with dietary “restrictions” and toxic medications – natural health experts like, Gabriel Cousens, MD are revealing a much better way to go.

According to Dr. Cousens, diabetes can indeed be successfully treated and cured.

Discover a highly-effective, proven way to naturally eliminate the threat of diabetes. On the next NaturalHealth365 Talk Hour, Jonathan Landsman and holistic physician Gabriel Cousens, MD talk about a LIVE, plant-based approach of eating that can stabilize blood sugar, help to prevent diabetes, and even get rid of the horrible condition – which causes cardiovascular disease and premature death. If you or someone you love has diabetes (or prediabetes) – be sure to tune into this informative show.

‘Conscious’ consumption of plant-based foods will promote dramatic reductions in blood sugar

According to Dr. Cousens, a plant-based diet is one of the keys to reversing diabetes. Conscious consumption of these foods will allow the body to reverse many of the degenerative disease processes that cause diabetes – and promotes dramatic reductions in fasting blood sugar levels.

Along with lifestyle, exercise, meditation and psycho-spiritual awareness training, a plant-based diet can reverse diabetes in a matter of weeks, Dr. Cousens reports. Other benefits include decreased body fat and increased cognitive abilities.

Using his protocol, Dr. Cousens says that 100 percent of non-insulin-dependent type 2 diabetics were off all diabetic medications after 3 weeks, while maintaining a fasting blood sugar of less than 100. Among insulin-dependent diabetics, medication use was reduced by 84 percent, again sustaining fasting blood sugar of under 100. Medically speaking, these are outstanding results!

In addition to a plant-based diet, Dr. Cousens sometimes advises juice fasts, using 100 percent organic green juice drinks, to reduce accumulated toxins and eliminate powerful cell-memory cravings. The bottom line: diabetes IS reversible – despite what conventionally-trained physicians have told you. Don’t miss the next NaturalHealth365 Talk Hour for greater details about the program that Dr. Cousens has been perfecting for 40 years and the incredible research behind it.

The power of nutrition: Wheatgrass juice has powerful anti-diabetic effects

Wheatgrass juice, a primary ingredient of green juice fasts, is a superfood with unique powers against diabetes. Scientifically known as triticum aestivum, wheatgrass is rich in antioxidants, amino acids and digestive enzymes – as well as beneficial chlorophyll, a natural liver cleanser and detoxifier that also reduces oxidative damage.

Wheatgrass is also rich in minerals – particularly iron, magnesium, calcium and the cancer-fighting nutrient selenium – and provides a good supply of the beneficial antioxidant vitamins A, C and E.

It also combats diabetes with its powerful anti-inflammatory effects, while helping to oxygenate the body, boost metabolism and rebuild damaged tissue. In addition, wheatgrass improves digestion and helps to maintain healthy weight. Research has shown that wheatgrass even has pain-relieving qualities and can promote restful sleep.

So, wheatgrass merely represents ONE example of the many ways that nutrition (when done properly) can help to literally heal the body. Don’t miss this opportunity to learn more about how to help yourself to be healthy again.

Chronic inflammation: The causes and solutions

Image: Chronic inflammation: The causes and solutions

(Natural News)
There is growing consensus – among holistically-minded healthcare providers and conventionally-trained physicians alike – that chronic inflammation is the root cause of chronic disease. And, as we all know, chronic diseases like, arthritis, cancer and diabetes, are a growing concern throughout the Western world. (for good reason – as you’ll soon see)

In fact, the National Council on Aging reports that a shocking 80 percent of people 65 and over suffer from at least one condition. (Of course, younger people can be affected as well.) Although Western medicine attempts to treat chronic inflammation with a variety of pharmaceutical drugs, these medications not only add a toxic burden to the body, but fail to address the real cause of the problem.

Find out how the right nutritional approach can eliminate the threat of chronic inflammation – naturally. On the next NaturalHealth365 Talk Hour, Jonathan Landsman and Dr. Stephen Lewis, a leading authority on nutrition and natural lifestyle strategies, will talk about the link between diet, inflammation and chronic disease. Plus, this show will reveal the best ways to safely prevent chronic disease symptoms without the need for toxic medications. Don’t miss this lifesaving news.

A steady decline in the quality of food is causing rampant inflammation

Inflammation in and of itself is not necessarily harmful. In fact, it is a natural response to injury and infection – the body’s attempt to repel invaders, repair damage and heal tissues.

With acute inflammation, which resolves within days, this reaction is appropriate and beneficial. It is only when inflammation becomes chronic – which happens in response to repeated trauma or long-term exposure to toxins – that problems arise, including the triggering of chronic disease. These can include cancer, asthma, allergies, Crohn’s disease, Alzheimer’s disease, Parkinson’s disease, diabetes, heart disease, arthritis, high cholesterol and high blood pressure.

A major cause of chronic inflammation, says Dr. Lewis, is the quality of our food, which has declined drastically over the past 50 years. The presence of environmental toxins, the depletion of nutrients from the soil and the primacy of pro-inflammatory GMO (genetically-manipulated) foods all conspire to create an overactive immune system, which triggers inflammation.

And the problem is widespread. Soy and corn products, which Dr. Lewis calls “the most modified foods in North America,” make up a large part of the Standard American Diet. Of course, many healthcare providers also point to gluten-laden foods – which can cause “leaky gut” syndrome, an increased permeability in the intestinal lining, that cause all kinds of health issues like, depression, anxiety, thyroid disorders – to name just a few.

Bottom line, all of this is avoidable with the right information. Be sure to tune into the next NaturalHealth365 Talk Hour with Jonathan Landsman and Dr. Lewis for an important show about your health.

A natural way to reduce inflammation by improving the digestive system

To deal with chronic inflammation, Dr. Lewis advises a ‘four-step protocol.’ Increasing nutrients, decreasing toxins, repairing leaky gut and introducing “friendly” digestive enzymes can help eliminate inflammation – and stop chronic degenerative diseases in their tracks.

One of the most potent natural remedies advised by Lewis is bromelain, a digestive enzyme obtained from fresh pineapples. Bromelain specifically breaks down proteins, while helping the body absorb valuable nutrients more effectively. Bromelain can also help heal and repair the digestive tract.

In addition, bromelain is a potent anti-inflammatory agent that can stand up to prescription medications in clinical studies. In one study, a combination of bromelain and two other enzymes was as effective as pharmaceutical non-steroidal anti-inflammatory drugs in reducing knee pain from osteoarthritis – and accomplished this without unwanted side effects.

Bromelain, available in convenient capsule form, can be used for a variety of digestive issues, including inflammatory bowel disease, ulcerative colitis, constipation and Crohn’s disease. Antiviral and antibacterial, this versatile enzyme is also used for post-operative pain and swelling — as well as the treatment of asthma, allergies and sinus infections.

This is just one example of the many things we will discuss on the next NaturalHealth365 Talk Hour.
