How are ecological, biological, organic and sustainable foods different?



Do you know what are the nuances that differentiate ecological, biological, organic, and sustainable products? Although more and more people are betting on these types of food, most people use these adjectives as synonyms. We explain their differences to you.

Healthy food is in vogue for many years, but still, many people confuse the terms. In fact, and as a study commissioned by Unilever pointed out a few months ago, 64% of Spaniards believe that ecological, biological, and sustainable are very similar concepts when we talk about food, while two out of ten consider that their meaning is identical.

The study also pointed out that almost half of the population (41%) perceive organic food as more natural, while a third of those surveyed rate it as tastier and healthier, although 27% believe that its price is too high. An identical percentage believe that it is worth opening the portfolio more to acquire them. 58% of consumers associate eggs with organic sales, second only to fruits and vegetables.

Although the European Community legislation considers synonyms the adjectives ecological -commonly called “eco” -, biological – “bio” -, organic and sustainable, designating those products that have not been designed or treated under chemicals or pesticides, which have not received genetic manipulation and that respect natural cycles, benefiting the environment and local livestock and agricultural communities, the truth is that there are some small differences and nuances between these concepts.

Definition and differences between eco, bio, organic and sustainable products

It is important to note that the use of one of these terms is usually done to highlight a specific aspect of the product. The European regulation requires that products of this type can not exceed 5% of ingredients from genetically modified organisms (GMOs), justifying the percentage as the tolerable range that can control the products  Consider the differences between these concepts related to responsible purchasing and the defense of the environment:

  • Organic food: It covers those products that develop all their stages of growth and production respecting the cycles of nature and without artificial intervention. Therefore, they are those that are grown and processed without fertilizers, pesticides, or genetic preservatives, nor irradiation, nor genetic engineering. Natural fertilizers are used for its cultivation, natural conditions such as soil or climate are used, and in the case of livestock, breeding is respected in optimal conditions -sufficient space or grass in the open air-, without intervention such as hormones or antibiotics. Organic foods contain fewer pollutants and nutrients with pro-oxidant and pro-inflammatory actions and a higher quantity of nutrients with anti-inflammatory and antioxidant actions.
  • Organic food: This term – so common in the food market, in which products with a bio prefix have been abundant for many years – names those foods that do not contain any component that has been genetically altered or received laboratory interventions to achieve the final result.  In this way, these producers carry out a natural process of species selection, close their reproductive cycle and improve their genetic heritage and support the preservation of high levels of biodiversity.
  • Organic Food: The “organic” label emphasizes that no chemical intervention has been made to develop the food and therefore no fertilizers or pesticides have been used in its production. It should be emphasized that not all organic foods are biological since they may not contain chemical substances but may have been genetically manipulated.
  • Sustainable food: The term is broader and is linked both to the environment and to the local economy and commerce. The sustainable economy is a form of production that enhances the local economy in the medium and long term and respects the planet and the environment, based on ecologically and ethically responsible cultivation. While, for example, organic farming is synonymous with sustainable agriculture, organic products – without pesticides or chemicals – can be produced on factory farms that are not sustainable.

Why do they say you have to brush your teeth before drinking coffee and never after



It has always been heard that coffee causes the teeth to be more yellow, but why do they say that it is good to brush your teeth before drinking it and not after?

When it comes to proper oral hygiene, you have surely heard comments on many occasions about how coffee makes your teeth more yellow and how good it is to wash them afterward. However, some specialists recommend that the opposite order be followed: brush your teeth before drinking coffee.

This is one of those situations that can provoke questions, like when you read that it is not advisable to drink coffee on an empty stomach. Have you been given the wrong instructions? But there are really dentists who bet on that order, brush their teeth and then drink coffee, like the American Christina Meiners.

In the HuffPost, they have asked this dentist about the situation and her explanation is that if the accumulation of bacterial plaque is eliminated before drinking coffee, it is more difficult for it to leave stains on the teeth.

Removing any residue or stain causes the coffee to not be able to grip anything on the teeth. Although it is recommended that afterward something is done to protect the teeth.

After drinking coffee, rinse your mouth with some water. This will prevent the enamel from weakening and the teeth from suffering any kind of problem. Without a doubt, a practice that can give food for thought and that you have probably never been told about.

According to this dentist, it can be chemically abrasive to rub teeth with toothpaste while maintaining the acidic environment left by coffee. An opinion that can undoubtedly cause many people to value how to maintain good health in the mouth.

Science explains why you should continue to wear a mask even after you have been vaccinated



Vaccines are the hope to mitigate the spread of COVID-19, but science makes it clear that you will have to continue wearing a mask for a long time, and we tell you how long.

Vaccines are humanity’s hope to eradicate the spread of COVID-19 throughout the world, and although there are already vaccines in circulation, at the moment a very low percentage of the population has been vaccinated, with which we still have several months until practically the whole world is immunized.

But certain people have already received the vaccine and doubt knowing if they have to continue wearing a mask and sanitise hands in public. The answer is clear and concise: yes, you will still have to wear a mask and use hand sanitisers. The answer is clear and concise: yes, you will still have to wear a mask. Of course, the different governments will relax the measures over time and according to the behavior of the virus and its mutations.

The point is that vaccinated people can still transmit the virus, and until 100% of the population, or at least a very high percentage, is not already vaccinated, the need and obligation of masks will be a fact anywhere in the world.

To understand the situation, something that TheGuardian explains even with animated graphics, once a person is injected with the vaccine, they begin to develop antibodies that will systematically fight against the virus. These antibodies will circulate to other parts of the body and protect us from the disease.

It should be noted that the coronavirus normally enters the body through our nasal cavities, and although we continue to have antibodies in the nose, it is likely that their number is lower and the virus may remain in our nasal cavities for a time until it is eliminated. That is why, even if you are vaccinated and are immune to the virus, it is likely that you have traces of the coronavirus in your nostrils, and therefore could potentially infect other people who have not been vaccinated .

On the other hand, it must be taken into account that due to the urgency of the pandemic there are still many studies in progress and it is unknown for how long current vaccines can protect us against the virus since it does not mean that once we are vaccinated, we can never become infected again.

The scientific community is also looking closely at the evolutionary changes in the virus with all these variants, which could make vaccines less effective, and which could force certain people who have been vaccinated previously, to have to be vaccinated again a few months later.

There will be short-term exceptions, such as you can meet non-partners in your home without wearing a mask if they are all vaccinated, but when it comes to public spaces, it will continue to be mandatory, at least throughout 2021.

So until the scientific community does not have many more solid studies, presumably at the end of the year, we will not know how long we must wear a mask on a mandatory basis despite being already vaccinated.

This company wants to build a hotel in space in 2025



With SpaceX, Blue Origin, and other private companies improving by leaps and bounds, it seems that the dream of traveling to space is closer than ever.

SpaceX has only just taken the first two astronauts to the International Space Station, but the Californian company Orbital Assembly wants to start building a hotel in space in 2025, inside the Voyager station, which could be operational in 2027.

Orbital Assembly claims to be the first large-scale construction company in space. You have completed the design of the Voyager station, as well as your own creative tools to carry out this incredible construction. Now the only thing missing is money …

His goal is that, by 2027, a hotel will be ready in space with a cinema, restaurants, a spa, and rooms for 400 people, with the best views of the Earth possible.

The Voyager station, which in addition to the hotel will house scientific experiments, will orbit 550 kilometers high, in a polar orbit that would allow it to receive sunlight 24 hours a day, to power its solar panels.

This private station will be twice the size of the International Space Station, with a diameter of 200 meters and a weight of 2,418 metric tons, six times more than the ISS.

As seen in the opening photo, it is shaped like a ring. It is divided into 24 modules of 12 x 20 meters, with an area of ​​500 square meters each, divided into three floors. At least half of them would be dedicated to the hotel:

Current technology already allows this type of construction to be carried out. And it is quite likely that by 2027 SpaceX and even Blue Origin will already have standardized the transport of travelers to the International Space Station.

So technologically it is possible. The problem, as you can easily imagine, is money. The Space Station has cost about 150,000 million dollars and is inhabited by 7 or 8 astronauts. The Voyager station will be twice as large and will house 400 people.

Orbital Assembly is in the process of attracting investors. The hook is a new business: space tourism, with a profit forecast of billions of euros.

The success of this acquisition of shareholders will depend on whether everything we have shown here becomes a reality. Good luck!
