In an editorial in The Hill, Marine Stewardship Council (MSC) CEO Rupert Howe urges the world to embrace sustainable and well-managed fish and seafood, or blue foods, as a key pillar for addressing the looming crisis of how to feed fast-growing populations.
Pakistan is facing a serious protein shortage that could be solved by increasing seafood consumption. A so-called ‘blue economy’, which emphasises sustainable development while preserving biomass like marine life and coastal resources, could also help strengthen the country’s financial and geostrategic standing.
Blue color is very rare in natural foods
One of the rarest colors in nature is blue. It doesn’t come up often in plant foods or in animals.
The blue color is usually a pigment called anthocyanin that’s found in blueberries, red cabbage, and other fruits and vegetables. It’s a natural antioxidant and is also the key to mixing other colors like green.
But it can also make food look unnatural. A team of researchers from the University of California, Davis, the Mars Wrigley Institute, and UC Riverside, have now discovered a new cyan blue that’s a natural alternative to synthetic blue food dye.
The research, published in Science Advances, shows that red cabbage is the best natural source of this new food coloring. The team has used an enzyme to convert the anthocyanin blue from a tiny fraction of red cabbage extract into a primary product.
Blue color is associated with toxic
The color blue reaches human eyes through a small window on the spectrum of colors, somewhere between violet and green. It has a dominant wavelength of 450-495 nanometres.
It is a rare color in nature, and its pigment is hard to find. In plants, the blue color is formed when a red pigment called anthocyanin is mixed with other pigments.
There are different shades of blue and each has a different meaning. Light blue carries qualities like health, healing, tranquility, understanding, and softness; dark blue is associated with knowledge, power, integrity, and professionalism.
Some people say that blue is a symbol of calmness, loyalty and tradition. It is also used in uniforms for hospital workers and police officers to represent the reliability, trust, cleanliness, order and stability.
Blue has many spiritual connotations in many cultures and religions. It is often depicted as the color of the Virgin Mary and is commonly found in UN peacekeeping uniforms. It is also considered to be a sign of divinity in Catholicism.
Blue color is not good for health
Blue is one of the least common colors in nature and rarely appears in plants. Its pigment, anthocyanin, is rare too, and can only be found in a very small number of flowers like morning glories, hydrangeas, and bluebells.
Even when it is found in plants, its color is rarely a solid one. Rather, it often appears in a mix of other hues or as a mixture of red and green pigments.
As a result, a diet that contains too much of it can be harmful to your health. Blue dyes in food have also been linked to cancer in animals. It is also absorbed through the gastrointestinal tract and may have dangerous effects on the brain and nervous system. The best way to avoid blue color is to buy foods from small farmers who use natural colorings. If you are unable to find such foods, then avoid eating blue-colored foods as much as possible.
Blue color is not good for eyes
The blue color is rare in nature, and even the sky isn’t always a bright blue. It usually looks hazy and grey, or sometimes white. It’s also a pretty rare color in human eyes. In fact, many people don’t even have a word for it.
Arshad was curious about how people could have such different colored eyes, so he asked his science teacher to explain why. She explained that not everyone has the same eye color; it depends on various factors, including how the iris scatters light and how much pigment the iris contains.
In Russian, Uruguayan Spanish, and some other languages, there is no single word for blue but rather different words for light blue (goluboy; Celeste) and dark blue (sinii; Azul). The shade of blue that you choose can have a huge impact on your designs and will influence how they are perceived by the public. For example, light blues can be refreshing and friendly, while dark blues are more serious and strong.
