There are plenty of reasons it’s important to maintain a healthy weight, and now you can add one more to the list: It may be good for your brain. Researchers have found that having a higher body mass index, or BMI, can negatively impact cognitive functioning in older adults.
Neu5Gc, a non-human sialic acid sugar molecule common in red meat that increases the risk of tumor formation in humans, is also prevalent in pig organs, with concentrations increasing as the organs are cooked, a study has found. The research suggests that Neu5Gc may pose a significant health hazard among those who regularly consume organ meats from pigs.
High cholesterol might harm more than our cardiovascular systems. New research using animal models suggests that high cholesterol levels trigger mitochondrial oxidative stress on cartilage cells, causing them to die, and ultimately leading to the development of osteoarthritis.
It’s not a fad diet, it is an actual diet — as in the way a person eats normally — and it may do more than just help your waistline. The Mediterranean diet can improve your mind, as well your heart.
A diet high in saturated fat can make your brain struggle to control what you eat. If people are looking to lose weight, stay clear of saturated fat. Consuming these types of fatty food affects a part of the brain called the hypothalamus, which helps regulate hunger.
Eating a type of powdered food supplement, based on a molecule produced by bacteria in the gut, reduces cravings for high-calorie foods such as chocolate, cake and pizza, a new study suggests. Scientists asked 20 volunteers to consume a milkshake that either contained an ingredient called inulin-propionate ester, or a type of fibre called inulin.
A direct and positive link between pupils’ breakfast quality and consumption, and their educational attainment, has for the first time been demonstrated in a ground-breaking new study carried out by public health experts at Cardiff University. The study of 5000 9-11 year-olds from more than 100 primary schools sought to examine the link between breakfast consumption and quality and subsequent attainment in Key Stage 2 Teacher Assessments* 6-18 months later.
Want fries with that diet soda? You aren’t alone, and you may not be “saving” as many calories as you think by consuming diet drinks. A new study that examined the dietary habits of more than 22,000 U.S. adults found that diet-beverage consumers may compensate for the absence of calories in their drinks by noshing on extra food that is loaded with sugar, sodium, fat and cholesterol.
Just like attempts at influencing hairstyles or clothing can backfire, adults who try to guilt middle-schoolers into exercising won’t get them to be any more active. The study found students who don’t feel in control of their exercise choices or who feel pressured by adults to be more active typically aren’t.
Biologically active molecules released by digesting bread and pasta can survive digestion and potentially pass through the gut lining, suggests new research. The study reveals the molecules released when real samples of bread and pasta are digested, providing new information for research into gluten sensitivity.
If you enjoy a daily soda, or other tasty sugar filled drink, you may want to put it down. New research shows that a daily sugar-sweetened beverage habit may increase the risk for non-alcoholic fatty liver disease (NAFLD). The study comes from researchers at the Jean Mayer USDA Human Nutrition Research Center on Aging (USDA HNRCA) at Tufts University and is bad news for anyone who loves sugary drinks.
You don’t need a crazy diet to lose weight. In fact, your typical fad diet won’t help you keep weight off long term and could be harming your health. If you want to know the secrets of healthier eating, think of the kitchen fruit bowl. A fruit bowl makes fruit more convenient, attractive, and normal to eat than if the same fruit were in the bottom of the refrigerator.
More bad news on the obesity front and strangely enough, on the popular diet front too — at least for diets like atkins. New research shows that even short term high-fat diets can change your metabolism. So while you might think that you can get away with eating fatty foods for a few days without it making any significant changes to your body, think again.
In a bid to help physicians guide obese and overweight patients who want to try a commercial weight-loss program, a team of Johns Hopkins researchers reviewed 4,200 studies for solid evidence of their effectiveness but concluded only a few dozen of the studies met the scientific gold standard of reliability.
You’ve probably heard of all sorts of diets, paleo, low-fat, low-carb, atkins, but now microbes may just be the next diet craze. Researchers have programmed bacteria to generate a molecule that, through normal metabolism, becomes a hunger-suppressing lipid (fat). Mice that drank water laced with the programmed bacteria ate less, had lower body fat and staved off diabetes — even when fed a high-fat diet — offering a potential weight-loss strategy for humans.
Think of it as interval training for the dinner table. Proponents of fasting style diets will be first to tell you there are health benefits, heck we’ve even covered some of the science here at the labs. Well new research shows that putting people on a intermittent fasting (or IF) diet may mimic some of the benefits of actual fasting, and that (ironically enough given their popularity) adding antioxidant supplements counteracts those benefits.
What started as an evolutionary protection against starvation has become a biological “bad joke” for people who need to lose weight. The human body doesn’t distinguish between dieting and possible starvation, so when there is a decrease in calories consumed, human metabolism increases its energy efficiency and weight loss is resisted.
While most research regarding fat loss focuses on the risks of being overweight, a new study shows that fasting, low-carb diets, or high-intensity exercise have specific health benefits. Specifically, researchers have found that a compound produced by the body when dieting or fasting can block a part of the immune system involved in several inflammatory disorders such as type 2 diabetes, atherosclerosis, and Alzheimer’s disease.
Does it seem like no matter what you do, you still can’t shed the pounds? You know what to eat, how to eat and workout regularly, but the weight just won’t go away, well you may not be alone. There are many different medical conditions that limit your ability to lose weight, but thankfully science has now found how to use your brain to shed the weight.
Losing the weight, some of us never seem to be able to do it. Whether it is poor choice in diet, a medical condition, or just a sedentary lifestyle, people everywhere are finding they can’t shed the pounds. Now there is a new drug that promises help in the weight loss department and works like nothing we’ve seen used for weight loss yet. The compound effectively stopped weight gain, lowered cholesterol, controlled blood sugar and minimized inflammation in mice, making it an excellent candidate for a rapid transition into human clinical trials.
The news isn’t shy in reporting the effects of being obese, high blood pressure, and diabetes (just to name a few). However, new research demonstrates that obesity does not always go hand in hand with metabolic changes in the body that can lead to diabetes, heart disease and stroke. Determining how and why may help reduce or eliminate the health risks in other people dealing with obesity.
Since the noticeable expansion of most of the worlds waistlines, people have come to lay the blame (amongst other things) almost squarely on fast food and ever increasing portion sizes. While the world and it’s leaders are dealing with this mysterious problem by trying to help push fast food chains in the direction of change, it might be surprising to know that according to new research, fast food portion sizes have changed little since 1996.
We’ve seen it on the news, we’ve probably even read some articles about it, the “western” diet is awful. Yet, despite the warnings, Americans as a whole still eat awfully. Unfortunately, the health effects are very real and a new study shows that it may not just be effecting an expected mothers health, it may be harming the unborn child as well.
In a new study, researchers have identified a key molecular mechanism behind the health benefits of dietary restriction — or reduced food intake without malnutrition. Also known as calorie restriction or simply a diet, dietary restriction is best known for its ability to slow aging in laboratory animals. The findings here show that restricting two amino acids, methionine and cysteine, results in increased hydrogen sulfide (H2S) production and protection against ischemia reperfusion injury, or damage to tissue that occurs following the interruption of blood flow as during organ transplantation and stroke. Increased H2S production upon dietary restriction was also associated with lifespan extension in worms, flies, and yeast.
Thanks to the internet age we have lost touch with the fact that there is a human out there reading these words. Because of this, the golden rule –treat others the way you want to be treated — went out the window. Making fun of “fat” people now seems to be a internet hobby and that insensitivity can (and does) bleed over into “normal” non-internet life. Now a new study shows that women whose loved ones are critical of their weight tend to put on even more pounds, which is probably no surprise to people who have experienced this behavior.
It seems like we’ve been on a weight loss campaign here at the labs, but there just has been so much new and interesting research on the subject to report on; this is no exception. Researchers have uncovered the mechanism by which white fat cells from humans (an important distinction) gets reprogrammed to become browner.
There is a heir of mystery surrounding weight loss and fat in general. Have you ever heard you have all the fat cells you’ll ever have — that’s false by the way. Then there is fad diets like gluten free — proven to do nothing unless you actually have a diagnosed gluten allergy — or adkins, but now researchers believe they’re on track to solve the mystery of weight gain – and it has nothing to do with indulging in holiday eggnog.
Free radicals, said in the right crowd and you might hear someone scream for their life. Of course, to be perfectly transparent antioxidants have already shown to be bad in plenty of cases, so maybe it’s just bad PR. Still they were long assumed to be destructive to tissues and cells causing a host of age related problems with them. Well new research is showing that “free radicals” generated by the cell’s mitochondria—the energy producing “powerhouse” structures in the cell—are actually beneficial to healing wounds.
Trying to drop the weight, but find yourself picking up more of it? Is your diet failing because you are so hungry you could eat a horse? Well a new study offers some, maybe obvious, but nevertheless helpful insights to help you wrangle in that waist line. A healthy diet will help you drop the weight, but if you aren’t sure what a healthy diet contains that might be a problem. If you are trying to cut the weight, but can’t fight the hunger you might just need to try beans!
The Mediterranean diet, it may have broad health benefits [let’s face it we can’t seem to escape the push for it here in the US], but a new study suggests that it doesn’t impart the same health benefits for everyone. In fact, new research shows that its impact on cognitive decline differs among race-specific populations.
Cholesterol, it’s bad for the heart. We know LDL bad, HDL good, eat healthier or ruin your arteries. I’m sure most of us have seen the public service announcements [at least here in the states]. But if that wasn’t a good enough reason for people to watch their cholesterol then how about cancer?An association between high blood cholesterol and breast cancer has been found in a study of more than 1 million patients over a 14 year time period in the UK.
Afraid to go into public because you think those double doors might be a little narrow for you? Are you pretty sure you have feet, even though you haven’t seen them for awhile now? Did you recently find something you think may have been a twinkie at one point in your folds? If you answered yes to any of these questions, then science might be able to help.
Believe it or not weight gain is complex –or at least the biological aspect of it– for example hormones control our appetite and even the uptake of food. In recent years, science has taken on the seemingly insurmountable quest of investigating these physiological functions and finding a medical way to fight the ever growing obesity epidemic.
Okay boys and girls, time to grab those love handles and hold on tight, because it’s another round of weight loss science fact. With a little luck [and a little reading] you won’t be holding them for long. With that let’s just jump right in, for those who are not in “the know” there are two types of fat: white adipose tissue and brown adipose tissue. The normal person’s body will preferentially choose white adipose tissue over brown. I’ll let you guess which one is the better of the two.
You, yes you! Put down the Big Mac, come on you can do it. Now, let’s get back to our roots. It’s time to go hunter gatherer on your ass. In fact, you might as well dust off your loincloths and pull out your clubs, because paleo here we come.
Do you have some of that unwanted belly fat? Do you get nervous that you will exceed the weight limit in an elevator? Do you want to eat everything in sight, but still lose the weight? Too bad, that is marketing, not science and if you want to lose the weight science can help, not so much the guy talking on the screen.
Fad diets, miracle weight loss super foods, and vaccines! Oh my! We live in the information age, a time where webMD will tell me what kind of cancer I am suffering from today and Dr. Oz will be more than happy to give me advice on the 5 superfoods I should include in my diet so I can live to see a healthy 160.
