Epistemology VI: Epidemiology
Epidemiology originally largely meant studying how infectious diseases spread, and that ' s still a major concern of epidemiologists. However, it also includes the study of any and every environmental or behavioral factor affecting human health. For example, the finding that smoking tobacco causes lung cancer (not to mention a bazillion other diseases) is an epidemiological finding. Epidemiology is largely an observational science, given the ethical prohibition against exposing humans to potentially hazardous conditions for experimental purposes. That ' s not to say it hasn ' t been done, with the victims being ...

Calorie Restriction as an Adjuvant Cancer Treatment
Calorie restriction and intermittent fasting have been extensively studied in the context of aging, and most of the age-slowing interventions so far tested in animal studies are derived in some way from a knowledge of the stress response mechanisms triggered by a lowered calorie intake. The long term effects of calorie restriction and fasting in short-lived species are quite different from those in long-lived species: only the short-lived species exhibit a meaningful extension of life span, as much as 40% in mice. Yet the short-term effects on metabolism and cellular mechanisms are very similar. The beneficial response to ...

7 Tips on How to Train Your Brain and Improve Your Memory
You're reading 7 Tips on How to Train Your Brain and Improve Your Memory, originally posted on Pick the Brain | Motivation and Self Improvement. If you're enjoying this, please visit our site for more inspirational articles.
Our memory is the part of the brain where we encode, store
and retrieve information. There are two types: our short term (or working
memory) and long-term memory. Short-term memory is how we remember things
temporarily, and it is thought that we can hold around seven items here at any one
time. When we no longer need this information however, it leaves us – unless it
makes it to our long-term memory...

Avoiding nuts and seeds for better gut health? You shouldn ’t
Nuts and seeds are important components of a healthy diet. But if you have diverticula — little pouchlike structures that sometimes form in the muscular wall of the colon and bulge outward — you may worry about nuts or seeds getting stuck in those little pockets, which can cause a painful infection called diverticulitis.
Take heart. While it was once believed that nut and seed consumption could lead to diverticulitis, the link is unproven.
In fact, quite the opposite is true. Nuts and seeds are rich in fiber, which is important for gut health and keeping you regular.
How much fiber do you need daily? If you’re over 5...

Common Dietary Supplements Have Little to No Effect on Mortality
Yet another sizable study has shown that common dietary supplements have little to no effect on late life mortality. This finding of course has to compete with the wall to wall marketing deployed by the supplement market. Researchers have been presenting data on the ineffectiveness of near all supplements of years, but it doesn't seem to reduce the enthusiasm for these products. In the past it was fairly easy to dismiss all supplements as nonsense, or at the very least causing only marginal effects that were in no way comparable to the benefits of exercise and calorie restriction, but matters are now becoming more complex....

Digesting the latest research on eggs
Eggs are back in the news — again. A study from the March 2019 JAMA found that higher intakes of cholesterol and eggs were associated with a greater risk of cardiovascular disease (CVD) and death.
The researchers reported that ingesting an additional 300 milligrams of cholesterol per day raised this risk, as did eating an average of three to four eggs per week.
Should we finally resign ourselves to taking our toast without a sunny-side-up yolk? Not so fast.
What did the study find?
Human diets are complex and notoriously hard to study. This is one reason why health headlines are often maddeningly contradictory.

Planet-friendly, plant-based home cooking
With all the news about the health and environmental advantages of eating less meat, many people are trying to eat more plant-based meals. But where do you begin?
Instead of trying to cook an entire vegetarian meal from scratch, start with one small step and build from there, says Dr. Rani Polak, founding director of the Culinary Healthcare Education Fundamentals (CHEF) coaching program at Harvard’s Institute of Lifestyle Medicine. “For example, buy some canned beans. You can then make a simple bean salad with a little olive oil and lemon juice. Or if you have a favorite recipe for beef stew, try swapping in beans for ...

Is there a place for coconut oil in a healthy diet?
Coconut oil has seen a surge in popularity in recent years due to many touted health benefits, ranging from reducing belly fat to strengthening the immune system, preventing heart disease, and staving off dementia. These claims are often backed by celebrity endorsements and bolstered by proponents of popular diets such as ketogenic and Paleo, with little support from scientific evidence. On the flip side, and further adding to the confusion, you also may have seen headlines calling out coconut oil as “pure poison,” implying that it shouldn’t be consumed at all. Given these contradictory claims, a question of much pub...

Benefits of a healthy diet — with or without weight loss
This study, called OMNI Heart (Optimal Macronutrient Intake to Prevent Heart Disease) examined 164 overweight and obese adults with prehypertension or Stage 1 hypertension, and replaced some of the carbohydrates in the DASH diet with either healthy protein (from fish, nuts, beans, and legumes) or unsaturated fats (from olive oil, nuts, avocado, and nut butters). Again calories were kept neutral to avoid weight gain or loss. Results showed that substituting healthy protein or healthy fats for some of the carbohydrate lowered LDL (bad) cholesterol, blood pressure, and triglycerides even further than the DASH diet alone.

Cracking the coconut oil craze
If you Google “coconut oil,” you’ll see a slew of stories touting the alleged health benefits of this solid white fat, which is easy to find in supermarkets these days. But how can something that’s chock-full of saturated fat — a known culprit in raising heart disease risk — be good for you?
Coconut does have some unique qualities that enthusiasts cite to explain its alleged health benefits. But the evidence to support those claims is very thin, says Dr. Qi Sun, assistant professor in the Department of Nutrition at the Harvard T.H. Chan School of Public Health.
“If you want to lower your risk of heart disease...

Eat better, live longer
In this study, researchers analyzed patient surveys between 1990 and 2012, food availability data from the Food and Agriculture Organization of the United Nations, and data on cardiovascular deaths in 2015. They estimated that the biggest contributors to the premature cardiovascular deaths of more than 220,000 men and about 190,000 women were due to
high consumption of salt and trans fat (a particularly unhealthy form of unsaturated fat commonly found in processed foods as “partially hydrogenated oils”)
low consumption of nuts, seeds, vegetables, and whole grains.
And here’s why it matters: Cardiovascular disease i...

Attention shoppers: Be wary of health claims on food packaging
If you’re like most nutrition-minded shoppers, the word “healthy” on the front of a package can be a big draw. “When you’re stuck in a situation where processed foods are the only thing available to you, it can be helpful to know which foods are healthier than others,” says Dr. Walter Willett, chair of the department of nutrition at the Harvard T.H. Chan School of Public Health.
Yet these days you’re on shaky nutritional ground if you rely on front-of-package claims like “healthy” and “natural” to determine which soup, sauce, cereal (or other canned, bottled, boxed, or bagged food) is the best choice...
