#Whey

[reasonsforhope]

"Scientists have developed a way to dramatically reduce the cost of recycling certain electronic waste by using whey protein.

Their method allows for the easy recovery of gold from circuit boards at a cost of energy and materials amounting to 50 times less than the price of the gold they recover—these are the numbers that big business likes to see.

Indeed, the potential for scalability depends on this sort of cost savings, something traditional e-waste recycling methods just can’t achieve.

Professor Raffaele Mezzenga from ETH Zurich has found that whey protein, a byproduct of dairy manufacturing, can be used to make sponges that attract trace amounts of ionized gold.

Electronic waste contains a variety of valuable metals, including copper, cobalt, and gold. Despite gold’s public persona as being either money or jewelry, thousands of ounces of gold are used in electronics every year for its exceptional conductive properties.

Mezzenga’s colleague Mohammad Peydayesh first “denatured whey proteins under acidic conditions and high temperatures, so that they aggregated into protein nanofibrils in a gel,” writes the ETH Zurich press. “The scientists then dried the gel, creating a sponge out of these protein fibrils.”

The next step was extracting the gold: done by tossing 20 salvaged motherboards into an acid bath until the metals had dissolved into ionized compounds that the sponge began attracting.

Removing the sponge, a heat treatment caused the gold ions to aggregate into 22-carat gold flakes which could be easily removed.

“The fact I love the most is that we’re using a food industry byproduct to obtain gold from electronic waste,” Mezzenga says. In a very real sense, he observes, the method transforms two waste products into gold. “You can’t get much more sustainable than that!” ...

However the real dollar value comes from the bottom line—which was 50 times more than the cost of energy and source materials. Because of this, the scientists have every intention of bringing the technology to the market as quickly as possible while also desiring to see if the protein fibril sponge can be made of other food waste byproducts.

E-waste is a quickly growing burden in global landfills, and recycling it requires extremely energy-intensive machinery that many recycling facilities do not possess.

The environmental value of the minerals contained within most e-waste comes not only from preventing the hundreds of years it takes for them to break down in the soil, but also from the reduction in demand from new mining operations which can, though not always, significantly degrade the environments they are located in.

[Note: Absolutely massive understatement, mining is incredibly destructive to ecosystems. Mining is also incredibly toxic to human health and a major cause of conflict, displacement, and slavery globally.]

Other countries are trying to incentivize the recycling of e-waste, and are using gold to do so. In 2022, GNN reported that the British Royal Mint launched an electronically traded fund (ETF) with each share representing the value of gold recovered from e-waste as a way for investors to diversify into gold in a way that doesn’t support environmentally damaging mining.

The breakthrough is reminiscent of that old fairy tale of Rumpelstiltskin who can spin straw into gold. All that these modern-day, real-life alchemists are doing differently is using dairy and circuit boards rather than straw."

Did some more cheese making, this time with chives.

This is the whey we collected from it.

We also made yogurt in a insta pot, it cooked for eight hours then we drained the whey from that too.

And here’s the cheese with chives.

Got some free logs from a local arborist today, big score. Also, this to me is why fitness is super important.

I'm healthy & strong, and can do tricky stuff comfortably. There should be many more decades of this.

I have a theory that you don't actually get old until you're between 60-70, but most people seem to give up at 40-50.

Fun Fact: The phrase "Get out of the way!" is an evolution from way back when, there bugs or other contaminants would get into the milk in the process of cheese making. The leftover liquid is called "whey" (like in your curds and whey). Cheese attendants would shout "Get out of the whey!" while dipping their hands in and flinging the bugs or contaminants out.

That evolved into it being used metaphorically -- if someone was blocking your path, you'd shout "Hey [person impeding my process / a nuisance]! Get out of the whey!"

Naturally as whey became less part of everyone's everyday life, the phrase evolved into using "way", as in meaning a path, and still retained its core meaning.

*Note: this is a lie I made it all up

The Best Chocolate Whey Protein Powders (Ranked)

Whey protein supplements are becoming popular for those looking to conveniently increase their protein intake. They are a wonderful addition to any well-balanced diet, that can help you achieve your fitness goals. During my weightlifting journey, I have tried many chocolate whey protein powders and have figured out what factors to look out for:

Value: Protein prices can fluctuate but generally brands can have ranges that they stick between.

Protein per serving (30g)

Taste

Fat and carbohydrate content: Low-quality whey protein will have high amounts of fat and carbohydrates and represents the amount of processing used to make the powder.

Mixability in water and milk: How easily the powder mixes in liquids without lumps.

Allergens: Whey protein obviously contains dairy and so may not be suitable for those with lactose intolerance.

These factors matter whether you're looking to build muscle, lose weight or just stay healthy.

Chocolate is typically a good flavour option for whey protein as it is made to be palatable to a wide range of people. Also, chocolate flavours are not usually too sweet or bland, when compared to other flavours.

If you have not tried any of the powders in this list, then you should consider trying them as I would recommend all of them for their unique benefits.

1. Optimum Nutrition (Double Rich Chocolate)

Out of all the brands I have tried, this one was the best overall. Its excellent taste and mixability easily justify its slightly higher price point.

4. PBN - Premium Body Nutrition Whey Powder (Chocolate)

PBN whey is the best budget-friendly choice, able to compete with even the best on this list. I was pleasantly surprised by the high protein per serving content and overall it has a great nutrition profile. However, I found that this protein struggled slightly with mixability and had a boring taste.

Protein Works' chocolate whey powder is a great choice, with a good nutrition profile. It suits all needs including muscular repair and weight loss and will help you achieve your goals. Its taste is too sweet, in my opinion, but if you can ignore that, this is a powder that mixes well.

Value: 3.5/5

Fat per serving (30g): 1.8g

Carbohydrate per serving (30g): 2.1g

Taste: 3.5/5

Overall: 3.9/5

6. Peak Supps Whey Protein Powder Concentrate (Chocolate)

Peak Supps prides itself on the quality of its whey protein, claiming its whey is sourced from grass-fed cows. I found that this protein mixes well with 50/50 water/powder by volume, providing a clean, premium-tasting protein shake. If you don't mind the price, this is a great quality protein powder, that feel extra healthy.

Value: 3/5

Protein per serving (30g): 23g

Fat per serving (30g): 2.3g

Carbohydrate per serving (30g): 1.8g

Taste: 3/5

Mixability in water: 3/5

Mixability in milk: 3.5/5

Overall: 3.2/5

7. Amfit Nutrition Whey Protein Powder (Chocolate)

This is another budget option that has good protein per serving. Also, its fat and carbohydrate content is perfectly average for protein powders on the market. Others would say that this is too sweet and artificial tasting and I would have to agree. Another gripe I had with this protein is that it takes a bit more effort to remove lumps.

I also had problems resealing the bag it came in, but nothing major.

Value: 4.0/5

Protein per serving (30g): 22g

Fat per serving (30g): 1.8g

Carbohydrate per serving (30g): 2.3g

Taste: 3.5/5

Mixability in water: 3.5/5

Mixability in milk: 3.5/5

Overall: 3.8/5

8. Bulk Essential Whey Protein Powder (Chocolate)

This would be a great protein powder as it tastes great, but its carbohydrate content is way too high at 8.2g per serving. This is much higher than its competitors and I would not recommend this to someone trying to lose weight. It is a shame as this is a great-tasting protein powder that mixes reasonably well with whatever you put it in.

Value: 4.0/5

Protein per serving (30g): 19g

Fat per serving (30g): 1.2g

Carbohydrate per serving (30g): 8.2g

Taste: 3.0/5

Mixability in water: 3/5

Mixability in milk: 3.5/5

Overall: 3.7/5

9. Warrior, Whey - Protein Powder (Chocolate)

For those on a tighter budget, this is a less popular choice, but a good one nonetheless. It is a high-protein powder with slightly higher fat and carb content than most. Its taste and smell are not extraordinary like the powders higher on this list, but it gets the job done. I would describe the shake consistency as a bit gritty and thick, but at this price point, it's hard to complain.

Value: 4.0/5

Protein per serving (30g): 22g

Fat per serving (30g): 2.3g

Carbohydrate per serving (30g): 2.9g

Taste: 3.5/5

Mixability in water: 3.0/5

Mixability in milk: 3.5/5

Overall: 3.6/5

10. My Sports Fuel Premium Protein (Double Chocolate)

As by far the cheapest on this list, the My Sports Fuel Whey Protein powder surprised me the most. The double chocolate flavour has a taste similar to Ovaltine. I would stick to water for this shake as the grittiness can be overwhelming went mixed with milk. I would say others will either love or hate this protein powder with no in-between. However, at its price, there is little harm in trying this brand as you may love it.

Value: 4.5/5

Protein per serving (30g): 24g

Fat per serving (30g): 0.2g

Carbohydrate per serving (30g): 3.8g

Taste: 3.0/5

La whey c'est important?

La whey, également connue sous le nom de protéine de lactosérum, est une forme de protéine dérivée du lait. Elle est souvent utilisée par les sportifs et les personnes pratiquant une activité physique intense en raison de ses nombreux avantages pour la performance et la récupération musculaire. Voici quelques raisons pour lesquelles la whey est importante pour les sportifs :

Teneur élevée en acides aminés essentiels : La whey est considérée comme une protéine complète car elle contient tous les acides aminés essentiels nécessaires à la croissance et à la réparation musculaire. Ces acides aminés aident à favoriser la synthèse des protéines musculaires, ce qui est important pour la récupération et la construction musculaire après l'entraînement.

Digestion rapide : La whey est rapidement digérée et absorbée par le corps, ce qui en fait une source de protéines idéale après l'entraînement. Elle peut fournir rapidement les acides aminés nécessaires aux muscles pour commencer le processus de récupération.

Augmentation de la synthèse des protéines musculaires : La whey stimule la synthèse des protéines musculaires, ce qui signifie qu'elle favorise la croissance musculaire et aide à prévenir la dégradation musculaire. Cela peut être bénéfique pour les sportifs qui cherchent à développer leur masse musculaire et à améliorer leur force.

Source pratique de protéines : La whey est disponible sous forme de poudre qui peut être facilement mélangée avec de l'eau ou d'autres liquides. Cela en fait une option pratique pour les sportifs qui ont besoin d'une source rapide de protéines après l'entraînement ou pendant la journée.

Soutien de l'immunité : La whey contient également des fractions de lactosérum bioactives, telles que l'immunoglobuline et la lactoferrine, qui peuvent aider à renforcer le système immunitaire. Les sportifs peuvent être plus vulnérables aux infections et à la diminution de la fonction immunitaire en raison de l'intensité de leurs entraînements, et la whey peut contribuer à atténuer ces effets.
