Is The Paleo Diet Heart Healthy – Also known as the “caveman diet,” the increasingly popular paleo diet is said to be good for weight loss, gut health, blood pressure control, and other factors. However, it can also increase the risk of heart disease, according to new research.
Intended to replicate the more “natural” diet people followed in the Stone Age, the Paleo diet emphasizes eating meat, vegetables, nuts and some fruit, while cutting out grains, legumes, dairy, salt, refined sugar and refined oils.
Is The Paleo Diet Heart Healthy
In a recent study conducted at Edith Cowan University in Australia, scientists looked at 44 adults who had been dieting for at least a year, along with another 47 who followed a traditional Australian (Western) diet. Among other things, the researchers found that people in the paleo group had significantly higher levels of an organic compound known as trimethylamine-n-oxide (TMAO) in their bloodstream. TMAO is produced in the gut, and high levels have previously been linked to heart disease.

It is thought that increased levels of TMAO are likely related to higher concentrations of the bacteria that produce the compound, which are also found in paleo diets. The abundance of these bacteria may in turn be due to the lack of whole grains in the diet.
“The Paleo diet excludes all grains, and we know that whole grains are a fantastic source of resistant starch and many other fermentable fibers that are vital for the health of your gut microbiome,” says lead scientist Dr. Angela Genoni. “Since TMAO is produced in the gut, a lack of whole grains may change bacterial populations enough to allow more production of this compound.”
In addition, it was noted that the high amount of red meat included in the diet provided the necessary compounds for the production of TMAO, as well as increased the intake of potentially harmful saturated fat to about twice the recommended level. Populations of beneficial bacteria, on the other hand, are lower in the paleo group, leading to an increased risk of other health problems.

New research has found that people who follow the Paleolithic or Paleolithic diet have high levels of a blood biomarker linked to heart disease. The finding raises some concerns about this type of diet, which researchers say is not balanced enough to ensure good health.
Paleo Diet Myths (with Infographic)
The Paleolithic diet—often known as the Paleo diet, for short—claims to mimic what the ancestors of modern humans ate.
People following a paleo diet have a high intake of meat, fruits, vegetables, nuts, and seeds, but no dairy, legumes, or whole grains.
This type of diet is surrounded by controversy and researchers debate whether it is safe and healthy.
For example, a 2016 study suggests that the Paleo diet may protect against heart attacks and cardiovascular disease by increasing blood levels of a protective molecule.

Another study the same year made the exact opposite finding, concluding that this type of diet leads to unhealthy weight gain and increases the risk of diabetes and cardiovascular problems.
Now, research from a team in Australia shows more evidence to suggest that people following paleo diets may be putting their heart health at risk.
The researchers come from four different research institutions in Australia: the Faculty of Medicine and Health Sciences and the Faculty of Science, both at Edith Cowan University, Joondalup. Curtin University School of Molecular and Life Sciences at Bentley. PathWest Laboratory Medicine, in Nedlands; and CSIRO Health and Biosecurity, in Adelaide. The researchers’ findings were published in the European Journal of Nutrition.
The researchers—led by Angela Genoni, Ph.D. — worked with 44 participants who followed paleo diets as well as 47 participants who followed standard diets that met national dietary guidelines.
The Paleo Diet And Why It Really Works?
The follow-up period was over a year, during which the researchers collected biological samples from all participants, assessed their diet and compared the results between the paleo group and the control group.
In addition, to be more precise in their assessment, the researchers divided the participants who followed the paleo diet into two additional groups, according to their specific preferences:
The researchers found that in the older groups, subjects had increased blood levels of a compound that experts have linked to heart disease: trimethylamine N-oxide.
Trimethylamine N-oxide is first formed in the gut, and its levels depend on a person’s diet and the bacteria that inhabit their gut, among other factors.

“Many proponents of the paleo diet claim that the diet is good for gut health, but this research suggests that when it comes to [trimethylamine N-oxide] production in the gut, the paleo diet may have adverse health effects heart. ” .” Angela Genoni, Ph.D.
“We also found that populations of beneficial bacterial species were lower in Paleolithic groups associated with reduced carbohydrate intake, which may have implications for other chronic diseases in the long term,” he adds.
Guenoni and his team argue that people on paleo diets have such high levels of trimethylamine N-oxide because they don’t consume whole grains. They are an excellent source of dietary fiber and help reduce the risk of cardiovascular problems.
“We found that lack of whole grains [was] associated with [trimethylamine N-oxide] levels, which may provide a link [to] the reduced cardiovascular disease risks we see in populations with high whole grain intakes,” says Genoni.
The Paleo Diet
“The Paleo diet excludes all grains, and we know that whole grains are a fantastic source of resistant starch and many other fermentable fibers that are vital for the health of your gut microbiome,” continues the lead researcher.
Additionally, the researchers point out that participants in the paleo diet groups also had higher concentrations of gut bacteria—
“Since [trimethylamine N-oxide] is produced in the gut, a lack of whole grains can change the bacterial populations enough to allow more production of this compound,” explains Genoni.
“Also, the paleo diet includes larger portions of red meat per day, which provides the precursors for [trimethylamine N-oxide] production,” he notes, “and paleo followers consume twice the recommended levels of saturated fat. worry.”

In the conclusion of their research paper, the researchers warn that cutting out whole grains from the diet can seriously affect gut health, with implications for heart health as well. They also say further research is needed on the role of vegetables and saturated fat in regulating key biological mechanisms in the gut. The Paleo diet is a nutrient-dense whole foods diet based on eating a variety of quality meats, seafood, eggs, vegetables, fruits, nuts and seeds. It improves health by providing a balanced and healthy diet, avoiding most processed and refined foods and empty calories.

Whether you want to lose weight, manage diabetes, reduce your risk of cancer and heart disease, reduce autoimmune disease, improve performance, or simply want to live your best possible health, a diet rich in all the micronutrients that the body needs while also skipping foods known to be problematic for health is your best bet. What does this diet look like? It is based on the most nutrient dense foods available to us, such as organ meats, seafood and a huge variety and large amounts of vegetables, with other quality meats, fruits, eggs, nuts, seeds, healthy fats, probiotics and fermented foods. herbs and spices to round it out. At the same time, foods known to cause inflammation, disrupt hormones, or negatively impact gut health are omitted, including all grains, most legumes, conventional dairy, and all processed and processed foods. Yes, this is the Paleo standard.
Over the past decade, Paleo has evolved from a relatively illegal movement into a diet that dominates news headlines, bestsellers, and even grocery store shelves. But despite its popularity, the scientific rationale for Paleo remains highly misunderstood and misrepresented. For example, we may know that grains are off-limits, that vegetables are fantastic, and that dietary fat is nothing to fear (despite years of low-fat pressure from various health authorities), but

Do these instructions exist? Here’s a hint: the answer has nothing to do with replicating what our early ancestors ate and everything to do with what modern science says is best for our bodies!
