Craft Beer is Advancing Science

We all know that craft beers are delicious thanks to all their fun flavours and now we also know that by drinking craft beer we are helping the world of science. The search for hop plants, which are integral to craft beer, has pushed science to go further into examining the plant and it’s neighbours – that means the world of botany is expanding. The drive for more varieties of hops has even led to using old ideas in new ways around what medicinal practices hops can be used for!

Flavor is driving the hunt. But, as it turns out, Matthews himself is not only, or even mostly, interested in flavor. The scientific byways, and possible medical uses, are more intriguing to him: the hipster I.P.A. quaffers are, in effect, advancing the frontiers of pure science, enabling the sequencing of the hop genome, and funding ethnobotanical excursions. “I was just in Tbilisi, at the Georgian botanical garden,” Matthews said. “People in Georgia are still into agroforestry—they pick wild strawberries and things in the forest. It turns out rural Georgians have for a long time used wild hops to cure their breads. Hops makes a powerful broad-spectrum antibiotic. It stops bacteria from souring the bread.”

The Georgians have also used hops as a folk medicine for reproductive health, to treat uterine pain, for example. This makes sense to Matthews since hops contain the strongest known plant-derived estrogen. “We are seeking to engineer it,” he said. “We think it can be used for hormone-replacement therapy—for example, in postmenopausal women.”

China Aims to Decrease Meat Consumption by 50%

Consuming meat as part of your diet increases your carbon footprint by a large factor. It take a lot more energy to produce meat than it does to produce plants. Indeed, many institutions have called for people around the world to consume less meat while increasing their fruits and veggies intake.

China has issued new dietary guidelines that encourage less meat consumption in hopes that it frees up resources (land, energy, etc.) for other means. Given the size of China’s population even a small percentage of Chinese changing their diets will make a difference.

New dietary guidelines drawn up by China’s health ministry recommend that the nation’s 1.3 billion population should consume between 40g to 75g of meat per person each day. The measures, released once every 10 years, are designed to improve public health but could also provide a significant cut to greenhouse gas emissions.

Should the new guidelines be followed, carbon dioxide equivalent emissions from China’s livestock industry would be reduced by 1bn tonnes by 2030, from a projected 1.8bn tonnes in that year.

Globally, 14.5% of planet-warming emissions emanate from the keeping and eating of cows, chickens, pigs and other animals – more than the emissions from the entire transport sector. Livestock emit methane, a highly potent greenhouse gas, while land clearing and fertilizers release large quantities of carbon.

Turning Beer Into Food

Eat Beer! Help ReGrained Grow – Barnraiser from Barnraiser on Vimeo.

Brewing beer requires a lot of energy since it involves heating large amounts of water and tossing in a bunch of plant matter. From there the plant matter gets tossed into compost (or in some places a landfill) to be reused. This plant matter is known as spent grain and you can use it again before it ends up as compost. A company called Regrained is taking those spent grains from brewers and turning them into food!

I’ve home-brewed beer and have used the spent grains to make cookies, and you can too. Here’s a guide how to prepare spent grains for baking if you also make your own beer.

That six-pack of IPA you enjoyed on Friday night generated about a pound of waste in its making. After brewers soaked barley (or sometimes other grains) in hot water and extracted the liquid to make beer, they’re left with a lot of spent grain on their hands. Most rural breweries, like Northern California’s Lagunitas or Sierra Nevada, haul the byproduct to nearby farms, which feed the grain to their animals. Others recycle it as compost. But for smaller breweries in urban areas, miles away from hungry pigs, figuring out what to do with the leftovers isn’t always easy.

The company Regrained turns that spent grain into snack bars. At a Meetup event in the Mission district of San Francisco, curious eaters lined up around the company’s booth, intrigued by the displayed logo “Eat Your Beer.” Cameron Schwartz, a tall man wearing a T-shirt with the same words, explained how his brother and buddies—all home-brewers—decided to open a business that takes beer byproducts and bakes them into bars, costing $2.50 a pop and sold at local grocery stores. So far, ReGrained has worked with three breweries in the Bay Area.

Eat Whole Grains for a Whole Lifetime

A simple change to your diet can make a whole lot of difference on your heart. Instead of reaching for the white bread go for the bread with the whole grains. It’s a pretty easy modification you can make to your diet. Just by switching to whole grains over bleached grains you can improve your health.

Give it a try and see how you feel!

People who ate the most whole grains were about 16 percent less likely to die of any cause during the study than those who ate the least, almost 20 percent less likely to die from cardiovascular disease and more than 10 percent less likely to die of cancer.

For every additional serving of 16 grams of whole grains, cardiovascular disease-related death risk declined by 9 percent and cancer death risk by five percent, as reported in the review in Circulation.

A half-cup of cooked brown rice, cooked oatmeal, or cooked 100 percent whole grain pasta, for example, or one slice of 100 percent whole grain bread, would be the equivalent of about 16 grams.

Food Good For You Is Good For The Planet

Producing food takes a lot of energy regardless of where it comes from, but some foods require a lot more input than others. In general it takes way more energy to feed people meat than it does a plant based diet because the animals need to be fed before they are slaughtered. A meat diet impacts the environment in a negative way.

Fret not though as you can greatly lower your carbon emissions by just eating less meat. It’s easy to be vegetarian, and it’s even easier to slowly transition to a plant focussed diet. Furthermore, not only is switching to a primarily plant based diet good for the planet it is also good for your health. It’s a simple way to make the world and yourself better.

If the global population followed the health eating guidelines published by the World Cancer Research Fund International and World Health Organization, greenhouse gas (GHG) emissions would drop 29 per cent compared to the baseline scenario. The elimination of red meat and poultry entirely would lower emissions by 55 per cent, while a vegan diet would reduce them by 70 per cent. Rates of early mortality would also decline by 6 to 10 per cent, depending on the scenario.
