When is a Vegetable Not a Vegetable?

When is a vegetable not a vegetable? When it's a potato, according to a new US government proposal to reclassify the starchy staple that has infuriated lawmakers in rural districts.

US senators Susan Collins and Michael Bennet -- a Maine Republican and a Colorado Democrat -- are spearheading a bid to convince government officials to back away from plans to call the root vegetable a grain, a move they fear would hurt farming.

"Since the inception of the US Department of Agriculture, it has classified potatoes correctly as a vegetable," Collins and Bennet said in a letter to both the USDA and the Department of Health and Human Services.

The proposals for stripping the potato of its "vegetable" status appear in the forthcoming Dietary Guidelines for Americans 2025–2030, produced jointly by the two departments, AFP reported.

Americans eat more potatoes than any other vegetable -- 50 pounds per person per year, according to USDA figures -- although almost half of those come in frozen form, for example as fries.

Nutritionists painted a grim picture of the country's consumption habits in a 2019 government study, estimating that just a tenth of adults eat enough vegetables.

And experts disagree on whether potatoes should count toward an individual's vegetable intake, as they are high in carbohydrates, which can cause spikes in blood sugar levels.

The senators pointed to a 2013 National Library of Medicine study that asserted that potatoes "should be included in the vegetable group because they contribute critical nutrients."

"There is no debate about the physical characteristics of the potato and its horticultural scientific classification. Unlike grains, white potatoes are strong contributors of potassium, calcium, vitamin C, vitamin B6, and fiber," they argued.

The senators said a change in the classification would confuse consumers, retailers, restaurateurs and growers.

Potato farming contributes $540 million in annual sales to the economy of Collins's state, according to online publication The Maine Wire, with 6,100 jobs linked to the industry.

Should You Stretch before Exercise? After? Never? Here’s What to Know

For many people of a certain age, high school gym class began with reaching for their toes. Then, over the years, we were told it was better to stretch after exercise.

It turns out, both those things can be true, but the differing advice has created some confusion.

Stretching can help make you more flexible, improve range of motion in your joints — and feel good. David Behm, who researches human kinetics at Memorial University of Newfoundland in St. John’s, Canada, offers this advice on when to stretch and how to do it safely:

Warm up first

It’s almost always good to stretch, but it’s better if you warm up first, said Behm, author of "The Science and Physiology of Flexibility and Stretching." He recommends a light aerobic activity such as jogging, walking or cycling for five or 10 minutes.

Follow that with some static stretching, the traditional way of reaching and holding a position (think back to that gym class). You can then do activity-specific dynamic stretching, in which you warm up the muscles with repetitive movements like leg lifts.

Behm says one minute is "the magic number" for how long to do static stretching per muscle group without fatigue.

Expand your definition of 'stretching'

Should you always stretch before exercising? If it's traditional stretching, not necessarily.

The better question, Behm says, is, "Should people increase their range of motion? Should people have better flexibility? And that is yes, because it helps prevent injuries. It helps with health. But you don’t have to stretch to achieve that."

Resistance training, for instance, can be an effective form of stretching, he said. Doing a chest press increases range of motion in your deltoids and pecs, whether with barbells, dumbbells or machines, so there is no need to stretch beforehand. Just make sure to start with a small amount of weight to warm up and then add more to train.

"You probably don’t have to do extra stretching unless you’re a gymnast, a figure skater, or even a golfer who needs a great range of motion through that swing," Behm said.

Nor do you need to stretch first if you’re going for a leisurely run. Simply start with a slow jog to warm up and then increase the pace.

Don't do it if it hurts

After exercise, "light stretching is OK, as long as you don't reach a point where you're feeling pain," Behm said. Since your muscles will be warm by that point, overdoing it makes you more likely to injure yourself.

Foam rollers can help with muscle recovery and have been shown to increase range of motion as well as stretching.

Do some static stretching before sports

If you’re playing a sport, Behm said, static stretching beforehand helps reduce muscle and tendon injury.

"If you’re going to do an explosive movement, change of direction, agility, sprint, any of these explosive activities that involve your muscles and tendons," he said, "you’re going to be stronger if you do static stretching."

People can especially get in trouble when they go back to a sport they used to play, whether it's tennis, surfing or any sort of team activity.

Also, stretch both sides equally. Lacking flexibility on one side also can lead to injury.

Sounds simple. Why all the confusion? Different studies over the years have either encouraged or discouraged stretching before exercise. Behm says that partly because some studies didn't reflect real-life conditions, or were designed with elite athletes in mind, not regular people.

"If you’re Usain Bolt, it makes a difference," said Behm. Not so much for the rest of us.
