United States: It does indeed already often taste so much worse, yet perhaps there is an even greater reason not to drink instant coffee.
Chinese scientists claim that they have discovered a correlation between instant coffee and a disease that makes the central vision blurry or distorted.

They discovered that instant coffee lovers had up to 7 times increased chances of developing the disorder as compared to drinkers of other coffees.
It is a disorder known as age-related macular degeneration (AMD), in which the small central portion of the retina wears out, and it causes people to have impossibility reading, driving, and recognizing faces, Daily Mail reported.
Scientists suspect the association to be associated with the processing of instant coffee, which liberates a chemical referred to as acrylamide, which can be considered to enter the bloodstream and harm the retina.
“People at high risk of age-related macular degeneration should avoid instant coffee,” the expert noted.
Those with a family history of the disease, the overweight, smokers, and people with high blood pressure are all at risk of contracting the disease.
Individuals who have blue or green eyes are also at a higher risk of getting it since their eyes have lesser pigment; hence, they are able to damage the eyes better than individuals with dark eyes.
However, the authors of the study warn that it was an observational study and does not demonstrate that consumption of instant coffee can lead to AMD.
Other research findings have, in fact, indicated that coffee may pause the incidences of AMD.
A 2023 study of 67,000 adults associated coffee consumption with getting nerve fiber layers thicker in the eye, which protects vision.
The new research, however, is among the few to investigate different kinds of coffee, as Daily Mail reported.
The paper employed the data on the individuals of the UK Biobank and the FinnGen consortium that records genetic data on individuals in Britain and Finland.
The researchers did not specifically examine whether an individual consumed instant coffee; they applied a different methodology, which is based on genes.
