The alkaline diet is a myth!

The diet dogma pervades, this time it’s with the alkaline diet that promotes eating “alkaline” foods to help prevent the blood from becoming too acidic.

I recently listened to an online webinar given by a so-called nutrition “expert” who has studied many nutrition modalities and was promoting the notion of eating alkaline foods, mainly fruits and vegetables and some grains and legumes, in order to keep your blood pH healthy. Although she didn’t explicitly say this, her message was quite clear that she was not a fan of eating meat, dairy, or fermented foods because they are very “acidic.” She also mentioned that studies have shown that cancer cells grow in more acidic environments.

Dietary patterns associated with autism spectrum disorder more than specific gut microbiome associations

April is World Autism Awareness Month which raises awareness about these conditions that impact communication, social interaction and behavior affecting about 1 in 160 children worldwide and 1 in 44 in the US.

There is a growing interest in the role diet plays in behavior, yet current studies have yielded inconsistent results directly linking the gut microbiome as the cause of certain behaviors such as anxiety and depression.

Probiotics vs prebiotics: which is better for gut health?

There has been a recent explosion in research that shows that our gut flora is linked to so many diseases-- cancer, autism, diabetes, heart disease, Alzheimer’s-- and the list goes on and on.

The microbes that inhabit our guts consist of about two million genes compared to only about 22,000 genes humans have, and they’re constantly affecting our health.

You can think of our gut microbiome as a rainforest. The more variety and number of species that inhabit our guts, the healthier the ecosystem of our intestinal flora will be.

Diet and food components shape the gut microbiome

The gut microbiota is linked to so many aspects of our health, and several recent studies have observed an imbalanced gut microbiota, also called dysbiosis, in conjunction with various non-infectious diseases such as obesity, diabetes, cardiovascular diseases and gastrointestinal disorders such as irritable bowel disease.

Luckily there are tangible ways we can change our gut microbiota composition. Diet has been shown to greatly impact the gut microbiota composition, which consequently also affects the production of beneficial short chain fatty acid production, intestinal barrier function and immune health.

Mediterranean diet: why would it be beneficial for the elderly?

A new study performed in the elderly from five European countries reveals that following a Mediterranean diet may positively affect the gut microbiota and health in this population.

Diet plays a crucial role in our overall and microbiome health, and the elderly are particularly vulnerable to suffering age-related health complications which could be related to changes in their diets.

Personalized nutrition still has a way to go

Personalized nutrition is still in its infancy but it is an increasingly important area of research that may one day help us better plan nutritional interventions to ensure a better response from patients.

When we’re faced with the question of which diet is best for our personal health, the answer isn’t easy. The individual response to dietary interventions varies greatly, and the gut microbiota likely plays a major role. However, several factors influence gut microbiota composition such as genetics, long-term dietary habits, hygiene, geographical location, exercise, as well as antibiotic and probiotic use making it a difficult area to study. Personalized nutrition studies aim to predict clinical response to dietary interventions based on the microbial composition, yet few studies have been conducted in humans.

A study casts doubt on the contribution of altered gut microbiota in autism spectrum disorder-related behaviors

There is a growing interest in the role diet plays in behavior, yet current studies have yielded inconsistent results around directly linking the gut microbiome as the cause of certain behaviors such as anxiety, depression and autistic behavior. A recent study tries to tackle the question of whether the gut microbiome is directly linked to autism spectrum disorders.

April is World Autism Awareness Month, a period for raising awareness about the conditions that impact communication, social interaction and behavior and affect about 1 in 160 children worldwide and 1 in 44 in the US.

Calorie restriction leads to weight loss but may promote pathogenic bacteria

Restrictive diets in terms of calories and nutrients are widespread among people. Although this type of diets could help with weight loss in the short term, their long-term effects on the gut microbiome and overall health remain unknown.

How diet affects a person’s weight appears to be much more complex than previously thought due to the potential role the gut microbiome plays in nutrient absorption, energy production, inflammation and metabolism.

It’s now well known that diet greatly influences the gut microbiome, and more recently research has shed light on how the gut microbiome is altered in obese vs normal weight individuals.

Long-term diet may affect the inflammatory effects of the gut microbiome more than specific foods alone

The purpose of the article is to uncover how dietary components and long-term dietary patterns interact with and influence gut microbiota composition and function and intestinal inflammation.

As the saying goes, an apple a day keeps the doctor away, but figuring out exactly how long-term dietary patterns affect the gut microbiome’s role in regulating inflammation has not been quite as clear for researchers.

Diet has been shown to play a role in both IBD and IBS symptoms and possibly disease progression

Protein consumption, the gut microbiota and health

Diet greatly influences gut microbiota composition, and evidence shows how the way gut microbiota metabolizes our food may be more relevant than the actual food we eat.

With so many diets and trends– high fat, low fat, low carb, Paleo, vegan, etc.– it’s hard to know which diet is best for our health. Diet greatly influences gut microbiota composition, and evidence shows how the gut microbiota metabolizes our food may matter as much as what we eat.

Cooking food alters the gut microbiome

Can cooking certain foods influence the gut microbiota? A team of researchers has set out to discover whether heat, which changes the properties of different foods, also affects the gut microbiota.

Studies have shown that diet, such as Paleo, high fat vs low-fat diet or Western diet, greatly impacts the gut microbiota composition even more than genetics. Surprisingly, little is known how cooking certain foods might alter the gut microbiota. Since heat changes the chemical and physical properties of foods, researchers wondered if this too affects the gut microbiota.

How to take care of your digestive health: regular fermented milk consumption can improve mild digestive symptoms

Occasional gastrointestinal symptoms are common in the otherwise healthy population. Most symptoms respond to dietary changes presumably via changes in the gut microbiota. Evidence shows that diet has a major impact on the gut microbiota and overall gastrointestinal health, and dietary interventions, such as consuming probiotics, especially Bifidobacterium, and the low oligo-, di-, and monosaccharide and polyol (FODMAP) diet, are recommended for different disorders. Physical activity may also improve the gut microbiota composition and appears to reduce digestive complaints, yet many studies analyzing the effects of diet and lifestyle are limited.

How diet affects menstrual pain

Diet and lifestyle have a major impact on your hormones and levels of inflammation all of which can in turn affect your period and menstrual pain. Most people blame their hormones directly for their period problems, but in reality, following an anti-inflammatory diet can be just as effective as taking ibuprofen (Motrin) or paracetamol (Advil). In fact, several studies have shown that an anti-inflammatory diet can be very effective at reducing menstrual and endometriosis pain.

The 15 best prebiotic foods for gut health

The importance of maintaining a healthy gut microbiome has been gaining more attention. 

The gut microbiome contains trillions of microorganisms, most of which are bacteria, and plays a major role in various aspects of our health. 

Probiotics and fiber have gotten a lot of fanfare lately when it comes to gut health, but in order to feed the “good bugs” or beneficial bacteria in our intestines, we also need to eat adequate prebiotics. 

Unlike probiotics, prebiotics are not live microorganisms, and although most prebiotics are different types of fiber, not all prebiotics are fiber. So what are they?

How to heal your gut

Ever since I was a little kid I have had stomach issues- vomiting, susceptible to stomach bugs, gas, bloating, etc. You name it, I’ve experienced it.

Unfortunately, as I grew older into my adult years, I didn’t outgrow my sensitive stomach. I finally went to a gastroenterologist who concluded that despite my symptoms of heartburn, gas, bloating and diarrhea, all I had was a mild case of acid reflux for which he prescribed me stomach acid blocking medicine.

I left his office infuriated because I knew that an antacid would not solve my underlying digestive issues, so I started to do my own research about digestive health and the gut microbiome and the role diet and lifestyle play in overall gut health, which has led me to publish various peer review articles about the gut microbiome and overall health. With some dietary and lifestyle changes I healed my gut which has greatly impacted my overall health and energy levels.
