fried foods

Fried food increases cardiovascular mortality risk – sorry KFC

As part of my ongoing series of articles that review interesting new studies, this week, I’m going to look at a new study that shows that fried food may be linked to increased risks of death from cardiovascular disease.

Now, some of you may be scratching your head and saying, “I’m sorry ye old feathered dinosaur, but tell me something I don’t know.” That’s the thing about science, we may think we know that eating a bucket of fried chicken or fish and chips is “bad” for you, but we can’t be sure until we have published studies that give us statistically powerful results.

Despite the beliefs by nearly everyone, including physicians, that fried food is directly linked to cardiovascular disease, studies have been inconclusive in establishing that link. A recent large prospective cohort study in Europe showed no link between fried food and coronary heart disease. The link between fried food and anything is hardly settled science, despite the conventional wisdom.

And since nearly 25-36% of Americans consume fast food, which presumably includes a lot of fried food, researchers wanted to reduce as many confounders as possible by narrowing the study group to women of a certain age.

And that’s what we have from a new study published in January 2019. Let’s take a look at the study and discuss what it may mean.Read More »Fried food increases cardiovascular mortality risk – sorry KFC

salt

Salt and cardiovascular health – not as evil as we once thought

If you are worried about your cardiovascular health, one of the things you want to avoid is salt. This was based on ancient research that seems to show even moderate salt intake could do all kinds of bad things for your cardiovascular system.

I was always skeptical of these claims because if you’ve got a healthy set of kidneys, the body has an amazing ability to regulate salt levels in the body. Of course, maybe there is some level of salt consumption that increases the blood pressure, cause retention of water, and other issues that lead to cardiovascular issues.

Recently, a very large prospective epidemiological study examined levels of salt consumption versus cardiovascular events. What did they find? Only high levels of salt consumption are linked to cardiovascular health.Read More »Salt and cardiovascular health – not as evil as we once thought

mediterranean diet

Mediterranean diet and cardiovascular diseases study retracted – “aw nuts”

Although I think that most diets are bogus and healthy outcomes are not very well supported by scientific research, I have been a proponent of the so-called Mediterranean diet. It seems to have been linked to lower risks of cancer, cardiovascular disease, and some other chronic health conditions.

The claims of researchers who stated that the so-called Mediterranean diet, rich in plants, olive oil, fish, nuts, and other foods, was linked to lower risks of cardiovascular disease. It was a pivotal and robust cohort study, a powerful form of epidemiological study that sits near the top of the hierarchy of medical research, that influenced a lot of recommendations about the proper diet for people. The study was so powerful that I switched to that diet personally.

But lucky for the planet, science is self-correcting, and some aspects of the original study caused concerns, and the Mediterranean diet study was retracted and republished with corrections.

Does this mean that the Mediterranean diet was and is bogus? No, but let’s take a look at the whole story.Read More »Mediterranean diet and cardiovascular diseases study retracted – “aw nuts”

dietary supplements

Dietary supplements make costly urine – not helpful for CVD

I have never been a fan of dietary supplements pushed by Big Supplement, the less regulated, less evidence-based, more pseudoscientific mirror image of Big Pharma. Recently, a meta-review published in a respected journal examined whether there were any causal links between various dietary supplements and cardiovascular disease (CVD). They only found one, folic acid, that might have an effect on CVD, but, in that case, causality might not be so clear.

Just to be perfectly clear, no one on the side of real science-based medicine would dismiss using dietary supplements to treat chronic medical conditions. Many people have had surgeries, illnesses, and other medical conditions where certain supplements are necessary for the patient to survive. But these are highly specific requirements, not general quack claims that taking supplements will somehow miraculously treat colds and flues, prevent cancer, or some other nonsense.

Essentially, if you’re taking dietary supplements for no medical reason other than you believe it makes you healthier, let’s stick to facts – all that you are doing is having your kidneys create some very costly urine. Human physiology, based on a couple of billion years of evolution, automatically regulates its needs for micronutrients – excess amounts do not stick around to make you healthier, it just becomes a component of your pee.

It’s time to take a look at this article about dietary supplements and cardiovascular disease. Maybe I’ll convince you to save some money each month, and spend it on something like investing in a better diet.Read More »Dietary supplements make costly urine – not helpful for CVD

statins prevent cardiovascular death

Statins prevent cardiovascular deaths – a new systematic review

Now for something completely different, let’s not talk about vaccines – we’re going to discuss statins! There have been more and more robust studies that statins prevent cardiovascular events, including death. Nevertheless, statins have been controversial, and are used by the alternative medicine (not medicine) lovers as an example of all kinds of medical malfeasance.

As I’ve mentioned before, I hang out on Quora answering questions about a lot of topics, mostly vaccines and cancer. But I also occasionally answer questions about statins, and I regularly state that statins prevent cardiovascular events. And just as regularly, I’ll get nasty comments (see Note 1) claiming everything from my being a Big Pharma shill to I don’t know anything about anything.

So let’s take a look at this new systematic review, and try to put to rest the nonsensical dismissal of the claim that statins prevent cardiovascular events, including death. Read More »Statins prevent cardiovascular deaths – a new systematic review

coffee health effects

Coffee health effects – what does the best science say

Coffee is one of the most consumed beverages worldwide, with tea being number one. And as I have mentioned previously, I am an unrepentant coffee lover. Over the years, there have been a number of claims about coffee health effects, both positive and negative, many without any solid scientific evidence in support.

Claims about coffee health effects goes back centuries. These claims were often confusing and contradictory. How many “studies” have we read about that said drinking it was good for your heart. Or bad for your heart. Or it prevented cancer. Or it increased your risk of cancer.

Part of the confusion is that the popular press, with its strange dependence on false equivalence, often presents two contradictory scientific studies as equivalent, even if they aren’t. Well, we’re going to look at a powerful new study that examined health outcomes that can be related to coffee. Let’s see what they say.Read More »Coffee health effects – what does the best science say

Lions, tigers and ebola–oh my!

ebolavirusUnless you’ve been living under a rock (which is admittedly difficult), you might be aware of the Ebola virus. And that it has entered the USA–one patient, not exactly an epidemic. And, according to public health officials, about 10 people are at risk from the disease from contact with this “patient zero” in the USA. Despite these minuscule, small, tiny numbers, you’d think America is facing a disaster of epic proportions.

Not so fast. I’m not saying we should ignore this disease, or minimize it’s danger, but seriously, in the grand scheme of the world, is this something to actually worry about? I have completely ignored the disease, other than mocking homeopaths for attempting to cure the disease, because there are so many infectious diseases that are actually more scary than Ebola.

Let’s get some facts then.Read More »Lions, tigers and ebola–oh my!

Vitamin supplements do not lower risk of cancer and heart disease

pile-of-supplementsVitamin and mineral supplements are important to maintaining proper levels of these nutrients when they aren’t obtained from the diet. Generally, if a human consumes a diet of broad based foods, there is little need for supplementation, unless they are afflicted with a chronic medical disorder which requires additional nutrients.

Vitamins and minerals do not have an impact on the immune system. Numerous articles have been published in peer-reviewed journals that have found very little evidence that supplements can lower risk of heart disease or one of the over 200 forms of cancer. What we need next, in the hierarchy of scientific evidence, is a systematic review published in an important journal.

And we got one.Read More »Vitamin supplements do not lower risk of cancer and heart disease
