By comparing how gut microbes from human vegetarians and grass-grazing baboons digest different diets, researchers have shown that ancestral human diets, so called “paleo" diets, did not necessarily result in better appetite suppression. The study reveals surprising relationships between diet and the release of hormones that suppress eating.
Perhaps one of the keys to good health isn’t just what you eat but how you taste it. Taste buds may in fact have a powerful role in a long and healthy life – at least for fruit flies. Researchers found that suppressing the animal’s ability to taste its food –regardless of how much it actually eats – can significantly increase or decrease its length of life and potentially promote healthy aging.
There is bad news for those who believe drinking red wine is protecting their hearts and extending their lives. A study found that a plant compound in grapes—resveratrol—may not provide such health benefits. The nine-year study found resveratrol had no significant effect on longevity, inflammation, cardiovascular disease, or cancer.
These days, more and more people seem to have food allergies, which can sometimes have life-threatening consequences. Scientists report the development of a new type of flour that someday could be used in food-based therapies to help people better tolerate their allergy triggers, including peanuts.
Eating more fruits and vegetables may reduce the risk of stroke worldwide, according to new research. The beneficial effects applied consistently to men and women, stroke outcome and by type of stroke.
If wine leaves a bitter, cotton-like coating on the tongue, neither the sense of taste nor the sense of smell is responsible. The traditional oak barrel character, also called barrique character, is perceived via the trigeminal nerve, which is responsible for, among other things, pain and temperature perception.
Activity in areas of the brain related to reward and self-control may offer neural markers that predict whether people are likely to resist or give in to temptations, like food, in daily life, according to research.
New research has helped unpick a long-standing mystery about how dietary fiber suppresses appetite. In a study led by Imperial College London and the Medical Research Council (MRC), an international team of researchers identified an anti-appetite molecule called acetate that is naturally released when we digest fiber in the gut. Once released, the acetate is transported to the brain where it produces a signal to tell us to stop eating.
520 million years ago, the first known animal heart, the heart of an ancient shrimp, was formed. Now, it, and its vascular system, have been found to be more complex than that of modern shrimp, researchers report.
We should eat even more vegetables than our governments— and moms— said. A recent study found that eating seven (or more) servings of veggies and fruits a day extends life by what the authors bill as a “staggering” 42 percent.
Be sure to pick up a watermelon—or two—at your local grocery store. It could save your life. A new study found that watermelon could significantly reduce blood pressure in overweight individuals both at rest and while under stress.
Improved thinking. Decreased appetite. Lowered blood pressure. The potential health benefits of dark chocolate keep piling up, and scientists are now homing in on what ingredients in chocolate might help prevent obesity, as well as type-2 diabetes. They found that one particular type of antioxidant in cocoa prevented laboratory mice from gaining excess weight and lowered their blood sugar levels.
Researchers at King’s College London and Imperial College London have discovered that people with fewer copies of a gene coding for a carb-digesting enzyme may be at higher risk of obesity. The findings suggest that dietary advice may need to be more tailored to an individual’s digestive system, based on whether they have the genetic predisposition and necessary enzymes to digest different foods.
Scientists at Plant & Food Research, working together with researchers at The University of Auckland and the National Cancer Institute of The Netherlands, have discovered specific plant compounds able to inhibit transport mechanisms in the body that select what compounds are absorbed into the body,and eventually into cells. These same transport mechanisms are known to interfere with cancer chemotherapy treatment.
Lab tests at Texas A&M AgriLife Research have shown that treatments with peach extract inhibit breast cancer metastasis in mice. AgriLife Research scientists say that the mixture of phenolic compounds present in the peach extract are responsible for the inhibition of metastasis, according to the study.
The health benefits of eating dark chocolate have been extolled for centuries, but the exact reason has remained a mystery. Now, researchers are reporting that certain bacteria in the stomach gobble dark chocolate and ferment it into anti-inflammatory compounds that are good for the heart.
A new study raises questions about current guidelines which generally restrict the consumption of saturated fats and encourage consumption of polyunsaturated fats to prevent heart disease. Researchers analyzed existing cohort studies and randomized trials on coronary risk and fatty acid intake. They showed that current evidence does not support guidelines that restrict the consumption of saturated fats in order to prevent heart disease.
The uplifting effects of energy drinks are well advertised, but a new report finds consumption among teenagers may be linked with poor mental health and substance use. Researchers are calling for limits on teen’s access to the drinks and reduction in the amount of the caffeine in each can.
A randomized placebo-controlled study by the University of Oxford suggests that higher levels of omega-3 DHA, the group of long-chain fatty acids found in algae and seafood, are associated with better sleep. The researchers explored whether 16 weeks of daily 600mg supplements of algal sources would improve the sleep of 362 children.
Beer drinkers know that hops are what gives the drink its bitterness and aroma. Recently, scientists reported that the part of hops that isn’t used for making beer contains healthful antioxidants and could be used to battle cavities and gum disease.
Some children who outgrow one type of food allergy may then develop another type of allergy, more severe and more persistent, to the same food. A new study by pediatric allergy experts suggests that healthcare providers and caregivers carefully monitor children with food allergies to recognize early signs of eosinophilic esophagitis (EoE), a severe and often painful type of allergy that has been increasing in recent years.
Increasing the number of calories consumed by patients with amyotrophic lateral sclerosis (ALS) may be a relatively simple way of extending their survival. A phase 2 clinical trial led by Massachusetts General Hospital physicians found that ALS patients receiving a high-calorie, high-carbohydrate tube-feeding formula lived longer with fewer adverse events than participants who received a standard formula designed maintain their weight.
“Sprouted” garlic—old garlic bulbs with bright green shoots emerging from the cloves — is considered to be past its prime and usually ends up in the garbage can. But scientists are reporting that this type of garlic has even more heart-healthy antioxidant activity than its fresher counterparts.
University of Adelaide research has shown for the first time that grape seed can aid the effectiveness of chemotherapy in killing colon cancer cells as well as reducing the chemotherapy's side effects. The researchers say that combining grape seed extracts with chemotherapy has potential as a new approach for bowel cancer treatment - to both reduce intestinal damage commonly caused by cancer chemotherapy and to enhance its effect.
Declines in the underlying brain skills needed to think, remember, and learn are normal in aging. Therapies to improve the cognitive health of older adults are critically important for lessening declines in mental performance as people age.
