Think of it as another example of a refined palate. The ability to make speech sounds such as “f” and “v” is due to diet-led changes in humans’ bite, researchers say. The range of speech sounds people can make was generally thought to be fixed since modern humans appeared about 300,000 years ago, but this new study challenges that theory. The findings suggest that sounds such as “f” and “v” — common in many modern languages — are a relatively recent development linked to humans’ eating habits. The teeth of adult humans used to meet in an edge-to-edge bite in order to cope with harder and tougher foods. As softer foods became available, the overbite that had previously disappeared by adulthood remained, with upper teeth slightly in front of lower teeth, the researchers explained. This enabled the emergence of a new class of speech sounds called labiodentals, now used in half of the world’s languages. These sounds are made by touching the lower lip to the upper teeth, as when pronouncing the letter “f.” “In Europe, our data suggests that the use of labiodentals has increased dramatically only in the last couple of millennia, correlated with the rise of food processing technology such as industrial milling,” said study co-first author Steven Moran, a linguist at the University of Zurich in Switzerland. “The influence of biological…  read on >

You’ll find plenty of nutrient-enriched flavored waters on grocery shelves, but are they any better for your diet than a glass of water with a squeeze of lemon? Many drinks promise health benefits, from more energy and better exercise performance to a stronger immune system. The latest fad is alkaline water, with claims that its manipulated pH has health benefits. But none of the claims of enhanced water products have been substantiated with serious research. In fact, Coca-Cola, parent company of Vitaminwater, voluntarily agreed in 2016 to remove claims from its labels to end a lawsuit brought by the Center for Science in the Public Interest seven years earlier. Drilling down into what’s inside the bottle brings up other concerns. Some products contain unnecessary nutrients. For example, most people who perform average amounts of exercise don’t need to replace electrolytes the way athletes do, and don’t need enhanced “sports” waters and other drinks, but there’s no science to support that either. Other products contain excessive amounts of some nutrients. Among 46 drinks tested in one study, most had at least one nutrient in excess of the daily required amount. Yet other than vitamin D, most Americans aren’t lacking in vitamins, and getting an abundance of certain nutrients can pose health risks. Of greater concern, whether you’re limiting calories to lose weight or want to eat…  read on >

(HealthDay News) — Overeating on a regular basis can lead to weight gain. About 25 percent of adults eat 1,300 calories weekly from food they buy or get free at work, the Academy of Nutrition and Dietetics says. The academy recommends limiting these workplace snacks: French fries. Pizza. Cookies and brownies. Soft drinks. Potato chips.

It’s hard to keep up with the findings from studies on the health effects of saturated fat — you know, the fat typically found in animal foods, from red meat to whole milk. But one thing’s certain. For every study that finds saturated fats unhealthy, there’s another showing that its role in heart disease and other chronic conditions is still open for discussion. For example, two studies published in 2016 were somewhat contradictory. The first, based on previously unpublished data from a Minnesota trial nearly 50 years earlier, found that replacing saturated fats like butter with vegetable oils high in linoleic acid, such as corn oil, didn’t lower the risk of death from heart disease or other causes. The second study, done at Harvard, followed more than 126,000 people, some for up to 32 years. It said replacing saturated fat is important, but what you replace it with counts just as much. The benefits of unsaturated fats high in omega-3 fatty acids, which are found in walnuts, flax seeds, soybean oil and fish, far outweigh the omega-6 fatty acids in corn oil, that study concluded. More recently, 2018 research from UTHealth in Houston looked at the saturated fats in dairy foods — from whole milk to cheese to yogurt — and found no link between their consumption and heart disease or stroke. So what should…  read on >

Celebrate spring with farm-fresh foods that usher in the season — asparagus, peas and watercress. They’re low in calories, have fresh flavor and are the perfect way to energize for warmer weather. Asparagus is the quintessential spring vegetable, high in iron, folate and vitamins K and A. Quick to cook and easy to pair with flavorful ingredients, asparagus can be a tasty side dish or the starring ingredient in a risotto or pasta main course. Asparagus is also great for digestive health, because it’s a pre-biotic, meaning it feeds the helpful bacteria that live in your gut. These good bacteria are responsible for everything from signaling your immune system and keeping digestion in check to producing vital B vitamins. When shopping for asparagus, look for spears that are free of blemishes and dry spots, and tips that are closed and firm. Use asparagus promptly — it can spoil quickly. Peas are high in fiber, vitamins C, K and B, and are easy to incorporate into many dishes. Watercress is a crunchy green with vitamin C, beta carotene, lutein, zeaxanthin and some B vitamins. It adds a peppery flavor to dishes and salads. Here’s a twist on a classic spring dish that showcases all these veggies and is deliciously creamy. Lighter Pasta Primavera 4 ounces whole-grain pasta 1 tablespoon extra-virgin olive oil 6 asparagus spears 1…  read on >

Has your hectic lifestyle turned you into someone who gulps down meals? People who eat quickly tend to eat moreand have a higher body mass index (a measure of body fat based on height and weight) than those who eat slowly. People who eat slowly feel full sooner and eat less in the process. Part of the reason for this is the time it takes for your brain to get key messages from your digestive system. Conventional wisdom says that’s about 20 minutes, and one study found that slowing down to 30 minutes is even more effective. But that means you have to find ways to really stretch out your meals. Tricks like eating with your non-dominant hand can help a lot, but eating fast can be a hard habit to break. One high-tech solution is a commercially available smart fork, a utensil that registers your eating speed and sends a signal, with a vibration and a flash of light, if you eat too quickly. Participants in an experimental study found that it was comfortable to hold and did a good job of making them more aware of their eating speed. But you can also try to slow down on your own with a regular fork: Just put it down and count to 10 between each and every bite. Reinforce the slower eating habit with…  read on >

You know that too much salt contributes to high blood pressure, but you might not realize how easily eating out could put you and your kids at risk. Many entrees at leading restaurants and fast food places contain almost a full day’s allotment of salt, according to the U.S. Centers for Disease Control and Prevention. Remember, that’s 2,300 milligrams, or about one teaspoon. With many Americans eating out an average of five times a week, all that salt adds up. And the more salt you eat, the greater the odds for high blood pressure (hypertension), a major contributor to heart disease and stroke. By some estimates, the average American takes in 50 percent more salt than the daily limit, and this excess starts in childhood. Kids between 6 and 10 years of age take in 2,900 mg a day, while teens top out at about 3,700 mg. Studies done around the world have looked at salt consumption and high blood pressure. A study of 500 people, aged 18 to 40, found that the more restaurant meals people ate every week, the higher their odds of pre-hypertension. Young people with even a slightly elevated blood pressure level are at very high risk of full-blown hypertension. About 80 percent of the salt consumed has been added by manufacturers of processed foods or at restaurants. While the salt…  read on >

Foods high in antioxidants — like kale, broccoli and blueberries — could be your ticket to better health, as long as you don’t cook the nutrition out of them. Some like it hot, but not the delicate pigments that give antioxidant-rich veggies their rich colors and health benefits. Choose cooking methods that provide gentle, quick or low heat. For instance, quickly sauteeing vegetables with olive oil for five to eight minutes over medium-high heat will cook them through without destroying all the nutrients. Another option is light roasting at 400 degrees for less than 10 minutes. Gentle baking for less than 30 minutes at 350 degrees will also do the trick. Blending is a fast, no-cook trick that makes these nutrients easier for your body to absorb. Try blending berries, yogurt and a few ice cubes with greens, such as kale and spinach, for a double antioxidant hit for breakfast. For foods with water-soluble nutrients, such as vitamin C, cook with the least amount of water possible. Put just one inch of water in a stockpot, then bring to a boil, add your sliced veggies and cover. Steam three to four minutes until tender-crisp, then serve. Remember that you don’t have to sacrifice flavor to preserve nutrients. This kale recipe is a tasty example. Parmesan Kale 2 teaspoons canola or grapeseed oil 5 ounces chopped…  read on >

With research finding that the body prefers calcium from food, not supplements, it can be a challenge to meet daily requirements if you’re lactose-intolerant. On average, adults need about 1,000 milligrams of calcium a day. Fortunately, there are choices within many food groups that deliver on calcium. Leafy greens are a great calcium source, and at the top of the list are cooked spinach, collard and turnip greens. Salad lovers, reach for raw kale. Calcium Content in Greens Cooked spinach, collard greens and turnip greens, 1 cup: 200 mg Raw kale, 1 cup: 90 mg Among legumes, beans and white beans in particular are calcium-rich, as are green soybeans, better known as edamame. Some brands of firm tofu made with calcium sulfate have more than half the daily requirement in a serving — check nutrition labels before you buy. Calcium Content in Legumes Cooked white beans, 1 cup: 160 mg Green soybeans, 1 cup: 260 mg Firm tofu, 3.5 ounces: up to 650 mg Some seeds and nuts also pack in calcium along with their unique mix of healthy fats, protein and carbohydrates. Choices include sesame seeds and tahini (sesame seed butter), chia seeds and amaranth, a seed that cooks up like a grain. Enjoy almonds as a snack or spread almond butter on your morning toast. Calcium Content in Seeds and Nuts Sesame seeds,…  read on >

People taking blood pressure medications have faced a frightening and bewildering series of pharmaceutical recalls in recent months, as trace amounts of cancer-causing chemicals have been discovered in individual batches of drugs. But experts from the nation’s leading heart groups are urging patients to remain calm, even as the recall list continues to grow. The trace amounts of carcinogens being found in these drugs don’t appear to pose an immediate cancer risk, and there are plenty of other medications on the market to help keep your blood pressure under control, said Craig Beavers. He is a member of the American College of Cardiology (ACC) Cardiovascular Team Council. The recalls center around generic versions of angiotensin II receptor blocker (ARB) drugs. Losartan, valsartan and irbesartan are the ARB drugs for which specific lots have been recalled. “Medications in the ARB class are used primarily for hypertension and for heart failure, and the good news is there are a lot of other alternatives,” said Beavers, an assistant professor with the University of Kentucky College of Pharmacy. Concerned patients should talk to their doctor or pharmacist about transitioning to an alternative, said Dr. Robert Carey. He is an American Heart Association (AHA) spokesman and co-lead for high blood pressure guidelines issued jointly by the AHA and ACC. Most importantly, people should not just stop taking their blood pressure…  read on >
