Sweet, Sour, Salty and...Fat? Scientists Add a New Basic Taste
The thousands of taste buds on a human tongue each contain as many as 100 taste receptors. The interaction between those receptors and the chemicals in our food determine the taste of that hamburger or salad you’re having for lunch.
Our sense of taste has long been broken into four basic categories — sour, sweet, salty and bitter. A fifth basic taste was added more recently: umami, which means “delicious” in Japanese but refers to a meaty or savory flavor sensation. Now researchers claim there’s a sixth basic taste.
Scientists at Purdue University have published a new study in the journal Chemical Sense that they say provides evidence that chemicals called nonesterified fatty acids (NEFA) — in other words, fat — causes a taste sensation that is different from the other five tastes. The researchers have proposed that the new taste be referred to as “oleogustus.” “Oleo” is the root word for oily or fatty in Latin and “gustus” means taste.

The researchers emphasize that they are talking about a taste, not just the creamy mouth feel you get from eating a rich piece of meat or a dish loaded in butter.
The fat that delivers that creamy, smooth feeling is a triglyceride, made up of three different fatty acids, they explain. Oleogustus — a gag-inducing taste on its own, but much more appetizing in combination with other flavors — comes from only one of those fatty acids that breaks off from the larger molecule in the food or as you’re chewing.
This finding has the potential to generate big changes in the food industry. Understanding the taste component of fat can do more than add to our knowledge of how our brain and digestive system interact. It may also help the food industry create more appealing, and potentially healthier, products.

Maybe Don’t Count Out Obamacare Repeal Just Yet
Sen. Bill Cassidy (R-LA) told reporters on Friday that he’s getting close to securing enough votes to pass the last-ditch ACA repeal and replacement bill he’s put forth with Sens. Lindsey Graham (R-SC), Dean Heller (R-NV) and Ron Johnson (R-WI).
“I am pretty confident we’ll get there on the Republican side,” Cassidy said. “We’re probably at 48-49 [votes] and talking to two or three more.” And Senate Majority Leader Mitch McConnell has asked the Congressional Budget Office to estimate the effects of the Cassidy-Graham bill, which would speed up the scoring process.
Of course, those last two or three votes have been the challenge for the GOP all along, and they may not be any easier to round up this time. Sen. Rand Paul (R-KY), who voted for a prior repeal bill, said Friday that he won't support this one. Plus, opponents are already stepping up their criticisms about the effects of the bill. And time is running out: Cassidy and his colleagues only have until September 30 to pass the bill this year under a process that would require only 50 supporters in the Senate. So while the Obamacare repeal may still have life, it remains a longshot.
Orrin Hatch Signals Just How Complicated Tax Reform Will Be
GOP leaders said Wednesday that they'd issue a more detailed framework of their tax overhaul the week of September 25. But while lawmakers are eager to get more details about the outline being hashed out by the so-called Big Six team of negotiators, Republicans are still divided on key elements of the plan — going from blueprint to bill is bound to be a contentious process.
In his opening remarks at a Senate Finance Committee hearing today on individual tax reform, Sen. Orrin Hatch (R-UT) said the plan from the Big Six — of which he is one — "will not dictate the direction" the tax-writing committee takes. "Anyone with any experience with the Senate Finance Committee knows that we are not anyone’s rubber stamp," he said. "If a bill – particularly on something as consequential as tax reform – is going to pass in this committee, the members of the committee will have to be involved in putting it together."
Oh, and remember: Republicans also need to agree on a budget before they can push through tax reform without Democratic votes.
Aging Baby Boomers Drive Down the Uninsured Rate
About 10,000 boomers turn 65 every day, becoming eligible for Medicare on their birthdays. The Census Bureau says that the sheer number of boomers entering Medicare is affecting the uninsured rate for the whole population. That rate fell to 8.8 percent in 2016, down from 9.1 percent a year earlier, with most of the decline driven by the aging of the post-war generation. (Wall Street Journal)
Social Security Kept 26.1 Million Out of Poverty Last Year
Social Security kept more than 26 million people out of poverty last year, according to a new report from the Census Bureau. Refundable tax credits such as the one for earned income kept 8.2 million people out of poverty, while food stamps lifted 3.6 million above the line, housing subsidies reduced the number of poor people by 3.1 million and unemployment insurance kept 680,000 out of poverty. Overall, the Census Bureau reported, the poverty rate was 12.7 percent, while a more sophisticated alternative measure that factors in government programs for low-income families put the rate at 13.9 percent, down from 14.5 percent in 2015.
