Water is, of course, important. Making up around two-thirds of our body weight, water carries nutrients and waste products around our bodies, regulates our temperature, acts as a lubricant and shock absorber in our joints and plays a role in most chemical reactions happening inside us.
We’re constantly losing water through sweat, urination and breathing. Ensuring we have enough water is a fine balance, and crucial to avoiding dehydration. The symptoms of dehydration can become detectable when we lose between 1-2% of our body’s water and we continue to deteriorate until we top our fluids back up. In rare cases, such dehydration can be fatal.
“One of fallacies of the 8×8 rule is its stark over-simplification of how we as organisms respond to the environment we’re in,” says Rosenburg. “We ought to think of fluid requirement in the same way as energy requirement, where we talk about the temperature we’re in and level of physical activity were engaged in.”
Most experts tend to agree we don’t need to be concerned about drinking an arbitrary amount of water per day: our bodies signal to us when we’re thirsty, much like they do when we’re hungry or tired. The only health benefit of drinking more than you need, it seems, will be the extra calories you expend by running to the loo more often.
The problem, he said, is not only what people are eating, but it’s also what they’re not eating. The study estimated that globally, 3 million deaths were attributed to too much sodium — but another 3 million deaths were attributed to a lack of adequate whole grains, and another 2 million deaths were attributed to a lack of adequate fruit.
Afshin said countries where people eat a Mediterranean diet — high in heart-healthy fats and fiber — scored the best using the researchers’ model, with Israel ranking No. 1 in terms of the least number of diet-related deaths. France and Spain ranked second and third, respectively, according to the research. Afshin defined the Mediterranean diet as one with a high intake of fruits, vegetables, nuts and healthy oils, such as olive oil.
The United States ranked No. 43.
Uzbekistan, a former Soviet republic where refined carbohydrates such as bread and pasta are staples, scored the worst, with a death rate of 891 per a population of 100,000.
Do you really know what you are eating for dinner tonight?
A study by the University of Guelph looked at samples of sausage collected by the Canadian Food Inspection Agency (CFIA) from 100 grocery stores across Canada. They found that 14 per cent of them contained meat from a source other than what was labeled.
Sausages labelled as beef were found to have sheep, pork, or chicken. Some chicken sausages were found to have turkey.
One concern is that the source of the mystery meat cannot be traced.
Increasingly researchers are finding that your intestines not only digest food, but may also regulate mood, emotion, and play a central role in your body’s response to disease.
What you eat feeds every single cell in your body.
Sushrut Jangi, The Boston Globe:
Avoid processed deli meats and red meat while feeding the dense jungle of bacteria in the colon with fibers, fruits, and vegetables. Siegel says unhealthy and sedentary lifestyles rife with fast foods and processed meats are contributing to the rise in colon cancer among young people. A lot of people go to the deli and buy very expensive turkey breast and think they are eating healthy, Siegel says. Shifting away from the standard Western diet to the Mediterranean diet — composed primarily of plant-based foods, olive oil, fish, and mixed nuts — supports both gut health and a healthy heart. Sprinkling food with curcumin — the activated ingredient in turmeric — may dampen inflammation. Routine exercise staves off obesity, which does wonders for the gastrointestinal tract and reduces cancer risk. While particular diets are effective in treating specific gut conditions, consult with a gastroenterologist or nutritionist before pursuing anything radical.
Regardless of who issues them, guidelines for health promotion and disease prevention universally recommend diets that are largely plant-based, meaning those that include plenty of fruits, vegetables, grains, beans, and nuts. The U.S. dietary guidelines also recommend foods in the “protein” category. Grains, beans, and nuts are good sources of protein, but the guidelines use “protein” to mean low-fat dairy, lean meats, and fish. Recommended eating patterns include all these foods, relatively unprocessed, but with minimal addition of salt and sugars. Such patterns provide nutrients and energy in proportions that meet physiological needs but also minimize the risk of obesity, type 2 diabetes, and other chronic diseases. One more definition: “Patterns” refer to diets as a whole, not to single foods. No one food makes a diet healthful. The healthiest diets include a wide variety of foods in each of the recommended categories in amounts that balance calories.
In their largely unprocessed forms, foods from the earth, trees, or animals are healthful by definition. So why, you might ask, would the producers of foods such as cranberries, pears, avocados, or walnuts fund research aimed at proving that these particular foods—rather than fruits, vegetables, or nuts in general—have special health benefits? Marketing, of course. Every food producer wants to expand sales. Health claims sell.
According to the Center for Disease Control and Prevention (CDC), more than one-third (37%) of adults in the U.S. will eat fast food on any given day. And it’s killing them.
What’s more, the higher their income, the more likely they were to consume fast food.
The percentage of adults who ate fast food rose with increasing income. About 32 percent of people who earn less than 130 percent of the federal poverty line — $32,630 a year for a family of four — ate fast food daily.
But 42 percent of people above 350 percent of the poverty line — $112,950 a year or more for that size family — were daily consumers.
A new study suggests that regular use of artificial sweeteners may impair blood-sugar control. The latest findings suggest consuming even less than half the amount approved by health authorities is not safe.
For the study, participants who don’t normally use the sweeteners were assigned to use 45 per-cent of the Health Canada acceptable daily intake (ADI). After only 14 days, these participants experienced an 18 per-cent reduction in insulin sensitivity, a risk factor for type-2 diabetes.
Sucralose, aspartame, acesulfamepotassium, cyclamate and saccharin are zero-calorie sweeteners approved in Canada.
Cyclamate (brand names Sucaryl, SugarTwin, Sweet’NLow) and saccharin are not allowed to be added to foods; they’re sold only as tabletop sweeteners.
Acesulfame potassium, aspartame and sucralose are allowed to be added to all sorts of foods including yogurt, baked goods, pancake syrup, ketchup, chewing gum, fruit juice and soft drinks. Sucralose (Splenda) and aspartame (Equal) are also available as tabletop sweeteners.
Health Canada considers these five artificial sweeteners safe when consumed in amounts up to the acceptable daily intake (ADI). The ADI is the maximum amount thought safe to consume each day over a lifetime.
According to a study published in the journal Molecules, researchers found that six common artificial sweeteners approved by the Food and Drug Administration and 10 sport supplements that contained them were found to be toxic to the digestive gut microbes of mice.
Researchers from Ben-Gurion University of the Negev in Israel and Nanyang Technological University in Singapore tested the toxicity of aspartame, sucralose, saccharine, neotame, advantame, and acesulfame potassium-k. They observed that when exposed to only 1 milligram per milliliter of the artificial sweeteners, the bacteria found in the digestive system became toxic.
“This is further evidence that consumption of artificial sweeteners adversely affects gut microbial activity which can cause a wide range of health issues,” Ariel Kushmaro, a professor in BGU’s department of biotechnology engineering, said in a press release.
Alcohol is linked to more than 200 health conditions, including liver cirrhosis and some cancers.
Alcohol kills three million people worldwide each year — more than AIDS, violence and road accidents combined, the World Health Organization said Friday, adding that men are particularly at risk.
The UN health agency’s latest report on alcohol and health pointed out that alcohol causes more than one in 20 deaths globally each year, including drink driving, alcohol-induced violence and abuse and a multitude of diseases and disorders.
Men account for more than three quarters of alcohol-related deaths, the nearly 500-page report found.
In the study of 68,273 Swedish men and women aged 45 to 83 years who were followed for 16 years, participants who most closely followed an anti-inflammatory diet had an 18% lower risk of all-cause mortality, a 20% lower risk of cardiovascular mortality, and a 13% lower risk of cancer mortality, when compared with those who followed the diet to a lesser degree. Smokers who followed the diet experienced even greater benefits when compared with smokers who did not follow the diet.
Anti-inflammatory foods consist of fruits and vegetables, tea, coffee, whole grain bread, breakfast cereal, low-fat cheese, olive oil and canola oil, nuts, chocolate, and moderate amounts of red wine and beer. Pro-inflammatory foods include unprocessed and processed red meat, organ meats, chips, and soft-drink beverages.
