One of the questions I get asked the most is where to turn for reliable sources of nutrition information. Well, from now on I will have this handy guide to direct them to. I’ve broken it down into categories so you can browse depending on what you are looking for. To make this list, the vast majority of the dietary information published must be based on quality scientific evidence. No one can be 100% accurate 100% of the time, but you must be handing out valid information on nutrition for at least ~90-95% of your content to remain on the list. The people listed here regularly discuss topics within the full context of available data, do not cherry-pick their sources and include those that may challenge their beliefs, interpret relevant clinical trials accurately and take into account their limitations, and frequently cite valid and credible sources.
This map shows dietary macronutrient composition per person. The dietary energy consumption per person is the amount of food, in kcal per day, for each individual in the total population.
Pamela Ronald studies the genes that make plants more resistant to disease and stress. In an eye-opening talk, she describes her decade-long quest to help create a variety of rice that can survive prolonged flooding. She shows how the genetic improvement of seeds saved the Hawaiian papaya crop in the 1950s and makes the case that it may simply be the most effective way to enhance food security for our planet’s growing population.
With the rising popularity of low carb/paleo type diets has come a curious unintended consequence: expecting mothers receiving a false positive on their Gestational Diabetes Mellitus (GDM) test
Gestational Diabetes Mellitus (GDM)
GDM is diabetes (“Type 4 Diabetes”) diagnosed in the second or third trimester of pregnancy that is not obviously type 1 or 2 . Women with diabetes in the first trimester would be classified as having type 2 diabetes . The essential contributing factor to GDM is pancreatic insufficiency . Basically, your pancreas is not making enough insulin for your body to overcome the increased insulin resistance due to the placental hormones of pregnancy and increased maternal adipose tissue, which could potentially cause your blood glucose levels to remain high.
GDM = weak pancreas. Not making enough insulin for you and the baby.
There have been a fair number of epidemiological trials that show light (up to 2/day) to moderate (up to 4/day) drinking is associated with reduced risk of coronary heart disease (CHD) and increased longevity [1,2,3]. Anything above 4 drinks a day and you are increasing your risk of cancer, liver disease, stroke, etc . This is what we call a J-shaped curve. At a lower dose we see benefits but as the dose gets higher we see relative risk increase.
Do you remember your English classes back in high school? The teacher would assign you some droll book to read and warn you of an impending test on said book. The night before the exam, you would sit down and Google as hard as you could to try and find the Cliffs Notes. Upon finding one, you would read through the summaries and hope it was enough to pass the test. This strategy would usually yield mediocre results. A passing grade but nothing too fancy. Sometimes, this strategy would earn you a big old F.
Some science writers never grew out of the Cliffs Notes phase and employ this strategy when reporting on journal articles. They will read through the abstract, the summary of a paper, and base their article on that single paragraph. Just like your high school English tests, these articles end up misinterpreting and misrepresenting the full context of the study.
So you're walking down the aisle of your local grocery store and you pass by the eggs. Other than there being approximately 30 different brands, you notice some of them carry this fancy 'natural' label (and probably cost $2 more per dozen). So what does this ambiguous label mean anyway?
Natural vs. artificial flavorings, what’s the deal?
Both of these are terms regulated by the FDA (the term "all-natural" is a different story). The definition of a natural flavoring is anything derived or extracted from a "spice, fruit or fruit juice, vegetable or vegetable juice, edible yeast, herb, bark, bud, root, leaf or similar plant material, meat, seafood, poultry, eggs, dairy products, or fermentation products thereof, whose significant function in food is flavoring rather than nutritional" . An artificial flavor is anything that is not derived from the items listed above, but rather
I consider America to be a very hospitable place, which is why I'm thrilled to see the US welcoming measles back into the country after 20 years of banishment. Good to have you back measles! You've been missed.
Plus, I think the red splotches all over your body make for a bold fashion statement.
Normally I never get sucked into the comment flame wars on FaceBook. I usually read them for amusement and never write anything myself. The trolls got me this time.
I happened to be looking through the comments on an anti-vaccination thread. In these threads, people never link to any legitimate scientific sources to back up their arguments. It just so happened that one woman attempted to back up her anti-vaccination beliefs by providing a link to an FDA document that she says provides "pretty incriminating evidence AGAINST vaccine safety". Stunned by seeing a link to a credible source, I decided to read this document to see if her claims were justified. Below is the exchange that took place.
