It should be noted that, while espresso has a reputation for being stronger, a single shot or 1. Espresso is more concentrated, though, as noted by Food and Wine , so sticking to the traditional portion size makes a single shot a wiser choice. A Harvard University study published in Diabetologia in observed men and women over the course of four years and found that those who gradually increased their intake of coffee reduced their risk of getting type 2 diabetes by 11 percent.
Conversely, those who decreased their intake saw their risk increase by 17 percent. Not a bad reason to drink espresso every day, huh? While one might assume it's the caffeine that's effectively at work, this has yet to be proven. Healthline cited a study that notes how "drinking caffeinated coffee over a long period of time may also change its effect on glucose and insulin sensitivity.
Still, this does not mean that a diabetic can and should freely chug their favorite coffee drinks. A study by the American Diabetes Association found that regular coffee drinkers with type 2 diabetes saw a big spike in blood sugar after drinking coffee. Multiple studies have shown a correlation between caffeine intake and memory retention, according to New Scientist.
Neuroscientist Michael Yassa conducted a study, cited by New Scientist , involving individuals who only consumed small amounts of caffeine.
They looked at images, and then were given a pill — either milligrams of caffeine about two shots of espresso or a placebo. New Scientist reported, "Receiving the caffeine after studying the images helped to isolate the effect of caffeine on memory, as you wouldn't expect alertness to matter at this point.
Ultimately, Yassa deduced that caffeine helped to boost long-term memory by helping with memory consolidation, or "the process of strengthening memories between acquiring them and retrieving them," as defined by New Scientist.
What's more, a study published in the Journal of Alzheimer's Disease in found that caffeine seemed to have a "protective effect" regarding the occurrence of Alzheimer's disease and other types of dementia — and research, cited by Healthline , showed a link between caffeine consumption and a decreased rate of Parkinson's disease.

Even the lead researcher admitted that people metabolize coffee differently, per Inc. Despite these rather significant caveats, there is still ample evidence that there is a positive correlation between moderate caffeine intake and one's heart health.

And because espresso is served without any added sugar, high blood sugar levels can be kept in check. Earlier, it was mentioned that some of the nutrients in espresso are antioxidants.
Put simply, antioxidants are molecules that neutralize free radicals before they harm healthy cells of the body. Free radicals may cause damage to the various parts of the cells, especially the DNA.
Since espresso is loaded with free radical-fighting antioxidants, drinking it on a regular basis may help fend off certain types of cancer.
