Knives In The Dishwasher – What’s The Correct Way?

There are a lot of differing opinions about how to put knives in the dishwasher. But is the correct way the safest way, or should they even be in the dishwasher at all?

A debate has broken out on the mildlyinfuriating subreddit on the proper way to get knives clean. Common sense should tell you when putting knives in the dishwasher to put the pointy side down because it's safer, but you'd think that having them face up would get them cleaner. There's even some dishwasher manuals that say you should have the pointy side up. One commenter said "I don't want the last bit of dirty water on the part that actually get used, I'm an adult and can avoid cutting myself."

Putting the knives pointy side down seems like the safer way to go so you don't stab yourself on one, but maybe the Florida climate I live in makes for a second reason. After the steak knives have been through the dishwasher a few times, they have little rust spots on them. So instead of debating pointy side up, or pointy side down - maybe don't put them in the dishwasher at all.

Another reason that came up in the discussion was that the detergents used in the dishwasher could dull the knife over time. Maybe. What I do know is that you should never put your knives in the sink when you're done using them. More items could be placed on top of the knives and then when you fill the sink with water to do the dishes, you could reach down and stab yourself with one. That has actually happened to me and tore my finger up. Quite a bit of blood.

If you've ever worked in a commercial kitchen, you know you don't put the knives in the dishwasher AND you don't put them in the sink. You wash and dry them when you're done using them. But that's for the food prep knives. What about butter and steak knives? I'm going to err on the side of caution and put all the utensils handle side up. Knives, forks, spoons, all of them. I'm not taking any chances.

As it turns out, people who live to 100 have certain things in common. It used to be that living to be 100 years old was very rare. You almost never heard of it happening. But, times are changing. In fact, according to experts, more people are projected to join the centenarian club in the next few decades than ever before.

Before we get into the things that people who live to 100 have in common, let's look at general trends. According to the latest projections from the experts at the U.S. Census Bureau, the number of Americans ages 100 and older is expected to more than quadruple over the next three decades. That's huge. Specifically, the number of people age 100 and older in America is projected to go from an estimated 101,000 in 2024 to roughly 422,000 in 2054. Currently, people who are 100 or older, often called centenarians, consist of just 0.03% of the overall U.S. population. That percentage is expected to increase to 0.1% in 2054. So, it will still be rare, but not nearly as rare. The centenarian trend has actually been going strong for a while. Over the past three decades, the U.S. centenarian population has almost tripled in size.

So, who makes up these folks who are living to be 100 and older? According to Census information, in 2024, 78% of centenarians are women and 22% are men. Their projections have women making up 68% of centenarians in three decades, with men making up 32%. Also, in 2024, according to the Census Bureau, 77% of centenarians are White, while 8% are Black, 7% are Asian, 6% are Hispanic and 1% or fewer are multiracial. In three decades, Census information projects that white adults will comprise 72% of the 100 and older club, Asians will make up 5%, Hispanics will comprise 11% and Blacks will make up 10%.

It's not just in America, either. According to recent data from the U.K.'s Office for National Statistics (ONS), 15,120 centenarians were living in England and Wales in 2022, which was a 3.7% increase from 2021. That was also the highest number of centenarians ever counted for the area and an impressive 100% increase from 2002 numbers. By 2030, more 21,000 centenarians are expected to be in the U.K., according to additional research.

So, what are some simple things that people who live to 100 do? Read on for a tally. Genetics is a part of it, but it's not all of it. It's a fallacy to think that just because someone has "good genes," they can live totally rough their whole life and not suffer any consequences. Sure, having good genes is nice, but there are some simple things that people who live to 100 do, so why not give these a try?

A new study published in the journal eBioMedicine looked at the DNA and lifestyle of seven centenarians to see what they had in common to live so long. The researchers found that people in the 100+ age group, not surprisingly, had a strong immune system that had allowed them to fight off a lot of illnesses. It helped them stay alive longer.

If having a good immune system isn't in your genres, according to the experts at Harvard, you can boost your immune system by eating a healthy diet with fruits and vegetables. Another way is to exercise regularly and have a healthy weight. A few other ways include getting enough sleep, only drinking in moderation, not smoking, staying up to date with immunizations and avoiding stress.

According to a recent study published in the National Library of Medicine, "The age at which 20% of each of the centenarian groups experienced morbidity was significantly delayed by between 18 and 24 years." That means these people got chronic illnesses much later than their peers. It helped them live longer.

This one shouldn't be a surprise. According to a National Institutes of Health study, 2.5 hours of moderate activity a week could increase your life by 3.4 years. Studies also show that places around the world with the most centenarians are often in places with rural communities, where they are up and walking around instead of sitting at a desk. So, get out and move.

Keeping their weight in check is apparently another commonality with people who make it to 100 years old. In a Harvard-Salk Institute paper about longevity, they note, "At present, calorie restriction remains the most robust [i.e., evidence based] strategy for extending health and lifespan in most biological models tested." So, eat, but do so mindfully. They also eat healthy, which goes along with longevity.

As they say, people need people. According to a research study via PNAS.org, having real, quality social ties with friends and family has been associated with better health. Also, being socially isolated has been associated with an increased risk of inflammation in people of different ages. So, don't be such a hermit.

According to a study published in the National Library of Medicine, "While there is no definitive scientific evidence linking directly spirituality and longevity some research suggests that spiritual practices and beliefs may have indirect effects on physical and mental health, which could potentially contribute to longer life spans." So, it's not a sure thing. But, it appears having beliefs and spirituality is something that many people over 100 share. Pray up, my friend.

A recent study published in GeroScience shows that those 100 years of age and older have some similarities in their blood. According to research, they have lower, but not super low, levels of creatinine, glucose and uric acid. Talk to your doctor about ways to get your blood to those levels, and talk to you doctor about any changes you plan to make to your lifestyle and diet, of course.
