Between juice bars and high-powered home juicing machines, drinking your fruits and veggies has certainly gone mainstream. Depending on the specific mixes you sip — a vegetable blend, for instance — juice can be a filling snack when you’re on the go. But is juicing a way to lose weight and boost health? Some juicing proponents claim that your body can better absorb nutrients in juice form. But there’s no scientific evidence of this — or that drinking only the juice of a fruit or vegetable is any healthier than eating the fruit or vegetable itself. Another claim is that juicing gives your system a break from digesting fiber. But the fact is that most Americans fail to get enough fiber in their daily diet. There’s also a lot of talk about juicing to get rid of toxins. But many health experts say the body removes toxins on its own. Juices may have some long-term health benefits — grapefruit, lemon, celery and red grape juices have all been the subject of research. But while experts agree that juices are a good way to get more fruits and vegetables into your diet, they shouldn’t be the only source of nutrients, as in a juice fast. No juice is a weight-loss miracle, and fruit juice in particular can cause spikes in blood sugar. Some fruit-based smoothies can… read on >

Twenty-three more illnesses caused by an E. coli outbreak tied to tainted romaine lettuce were reported by U.S. health officials on Wednesday. That brings the total number of cases to 172, the U.S. Centers for Disease Control and Prevention said. But there was potential good news: The outbreak, tied to lettuce grown near Yuma, Ariz., might be nearing its end. That’s because “romaine lettuce from the Yuma growing region is past its shelf life and is likely no longer being sold in stores or served in restaurants,” the CDC noted. “The last shipments of romaine lettuce from the Yuma growing region were harvested on April 16, 2018, and the harvest season is over.” In fact, the agency said the newest cases all occurred among people who first reported becoming ill two to three weeks ago. That’s “still within the window when contaminated romaine was available for sale,” the CDC said, and “the latest reported illness started on May 2.” The outbreak has been caused by a particularly virulent strain of E. coli O157:H7. Of the 157 cases reported with good information, 75 (48 percent) have resulted in hospitalization, and 20 people have developed a dangerous form of kidney failure. “This is a higher hospitalization rate than usual for E. coli O157:H7 infections, which is usually around 30 percent,” the agency noted. So far there has… read on >

While allergists have long known that farm life helps prevent allergies in kids, new research shows the benefit might even extend to adults who live near a farm. The findings “are indicative of potentially beneficial health effects of living in close proximity to farms,” said a team led by Dr. Lidwien Smit, of Utrecht University in the Netherlands. One U.S. expert said the study supports what’s known as the “hygiene hypothesis.” This theory holds that early exposure to immune-system allergy triggers — called antigens — actually helps prime the body against developing allergies. This theory was supported “when it was demonstrated that children growing up on farms developed less asthma and atopic diseases later in life,” noted Dr. Alan Mensch, a pulmonologist at Plainview and Syosset Hospitals on Long Island, N.Y. “This included allergies to grass, dust mites, and even cats and dogs,” he said. But is there any benefit to simply living near livestock farms for people who aren’t farmers or ranchers? To find out, Smit’s group surveyed 2,500 adults between 20 and 72 years old who lived in rural areas near farms. The Dutch team found that nearly 30 percent of the adults had allergies. Of these people, nearly 12 percent were allergic to grass, nearly 12 percent were allergic to house dust mites, around 5 percent were allergic to cats and about… read on >

The so-called “Paleo” diet, which cuts out a number of food groups to bring about weight loss, has been around for several years now and at first blush may sound like just another fad. But some recent scientific studies since the diet became popular have found that the regimen that makes up the diet’s requirements could have merit. A Paleo diet requires people to eat foods similar to those available to humans during the Paleolithic period, which dates from 10,000 to 2.5 million years ago, according to the Mayo Clinic. The diet typically includes foods that could be obtained by hunting and gathering — lean meats, fish, fruits, vegetables, nuts and seeds — and limits foods that became common with the advent of farming, such as dairy products, grains and legumes. This premise, however, is challenged by some experts who say that comparing modern conditions to those of our ancient ancestors is not realistic. Nevertheless, one possible benefit is that the Paleo diet can improve risk factors for metabolic syndrome, a condition that can lead to diabetes, heart disease and other chronic illnesses. One research review in the American Journal of Clinical Nutrition found that the Paleo diet did a better job of reducing waist circumference, blood pressure, cholesterol and fasting blood sugar than diets based on general health guidelines. Another study published in the… read on >

Your parents’ advice to eat your vegetables has solid science behind it. Filling half your plate with non-starchy selections, as well as some fruit, provides a high volume of low-calorie food that can tame hunger as it delivers important nutrients. A study done at Cleveland’s Case Western Reserve University School of Medicine provides more good news — the higher the ratio of vegetables and fruits to other foods you eat, the better you’re able to ward off heart disease and metabolic disease, a risk factor for diabetes. To get the widest range of nutrients, experts say to pick a rainbow — a mix of vegetables and fruits in every color. If you have to narrow down choices, put dark green and yellow-orange vegetables at the top of the list. That means choices like sweet potatoes, carrots and squash along with leafy greens, broccoli and Brussels sprouts. Citrus fruits and various berries are great fruit choices. If you’re on a tight budget, look for veggies that deliver the most nutrients dollar-for-dollar, according to a report in the Journal of the Academy of Nutrition and Dietetics. Based on data from the U.S. Department of Agriculture, the researchers identified the most nutrient-dense vegetables, offering essentials like fiber; vitamins A, C and E; and the minerals calcium, iron, magnesium and potassium. The results showed that tomato juices and tomato… read on >

(HealthDay News) — Electrolytes are naturally occurring minerals that contain an electric charge. They are found in your blood, urine, other bodily fluids and tissues. Examples contained in certain foods and beverages include: sodium, calcium, potassium, chorine, phosphate and magnesium. Electrolytes influence your body’s water balance. The U.S. National Library of Medicine says electrolytes also are important because they help: Balance your body’s acid/base (pH) level. Move nutrients into your cells. Move waste from your cells. Ensure that your nerves, muscles, heart and brain work properly.

New research sheds light on why some people’s blood pressure is especially sensitive to salt. The research team previously discovered that a natural gene variation that occurs in 48 percent of people increases a person’s chances of having blood pressure that’s sensitive to salt. Their new study revealed how this gene variant prevents the body from eliminating excess salt. The gene variant causes a sodium (salt) transporter called NBCe2 to overwork, bringing too much sodium filtered in the kidney back into the body, particularly after a high-salt meal. That means that consuming too much salt could be especially dangerous for people with this gene variant. Blood pressure that’s sensitive to salt can be difficult to diagnose and treat, according to the researchers, because about 14 percent of people can have normal blood pressure and still be salt-sensitive. About three out of 10 people are sensitive to salt and their inability to eliminate excess salt puts them at increased risk of heart attack, stroke, kidney failure and blindness, according to study senior author Robin Felder, from the department of pathology at the University of Virginia School of Medicine, and colleagues. “It’s important for the body to get rid of excess sodium because having too much sodium in the body causes the body to retain water, which can raise blood pressure and significantly shorten one’s lifespan,” Felder… read on >

The crunchy goodness of peanuts, walnuts, cashews and other nuts may be just what the cardiologist ordered, new research suggests. The study couldn’t prove cause-and-effect. However, the analysis of health data on more than 61,000 Swedes aged 45 and older found regularly eating nuts was tied to lower risks for heart failure and an irregular heartbeat, known as atrial fibrillation (“a-fib”). One U.S. heart expert said it’s fine to include the food in your diet. “There certainly is no harm, as nuts — in moderation — are a healthy sort of protein compared to other diets and possibly can be associated with better cardiovascular health,” said Dr. Rachel Bond. She helps direct women’s heart health at Lenox Hill Hospital in New York City. In the new study, a team led by Susanna Larsson of the Karolinska Institute in Stockholm tracked the health of the study participants for 17 years or until death, whichever came first. After factoring out age and gender, along with several other well-known heart risk factors — lifestyle, overall diet, diabetes and family history — high nut consumption was tied to lower odds for a-fib and heart failure. The more often people ate nuts, the lower their risk of a-fib, the investigators found. Specifically, the risk of the stroke-linked heart rhythm disorder was 3 percent lower among those who ate nuts one… read on >

It’s no secret that weight gain results from consuming too many calories. But at its core is an imbalance of healthy and unhealthy habits. On one side of the scale — the healthy side — are foods such as whole grains, fruits and vegetables, lean protein and plant-based fats. On the other side are the not-so-healthy options — sugary foods, those high in saturated fats, and packaged and processed foods. It’s not just the foods, though, that can cause weight issues. Unhealthy behaviors play a role, too. That’s because they can lead you to take in more calories, sometimes without even realizing it. A group of researchers in Spain identified key habits that promote a poor-quality diet. Things like frequenting fast-food restaurants, snacking from vending machines and eating while watching TV. But the researchers also determined that significant weight gain usually isn’t due to just one bad habit, but rather to a combination. To learn more, they followed 1,600 people for up to four years, focusing on the effects of seven specific unhealthy habits: Not planning how much you’re going to eat. Consuming pre-cooked or canned food. Buying snacks. Eating in fast-food restaurants. Not choosing low-calorie foods. Not removing visible fat from meat or skin from chicken. Eating while watching TV or sitting on the sofa. The more of these unhealthy habits people had, the… read on >

Forget what a hot chili pepper can do to your stomach: A new case report suggests that eating some of the hottest ones may give you a headache that can send you to the emergency room. A young man was taking part in a hot chili pepper eating contest and ate a particularly potent type called the Carolina Reaper, according to doctors from Bassett Medical Center in Cooperstown, N.Y. Some call the Reaper the world’s hottest chili pepper. The man immediately suffered dry heaves and over the next several days experienced intense neck pain and headaches, each of which lasted just a few seconds. After finally seeking emergency care, the man was tested for a number of neurological conditions, but all the results came back negative. However, a CT scan revealed that several arteries in the man’s brain had narrowed, leading to a diagnosis of thunderclap headache due to reversible cerebral vasoconstriction syndrome (RCVS). The syndrome doesn’t always have an obvious cause, but can occur as a reaction to certain prescription medications or illegal drugs, according to the report in the April 9 issue of the journal BMJ Case Reports. The researchers said this is the first such case linked with eating hot chili peppers, but they noted that consuming cayenne pepper has long been associated with a sudden narrowing of the coronary artery and… read on >
