Eating Walnuts May Do Wonders For Gut And Heart Health

Love munching on walnuts? Here's good news for you. According to a latest study, walnuts may do wonders for the good bacteria in your body, and boost both gut and heart health. The study was published in the Journal of Nutrition. The positive changes in the gut microbiome were associated with improvements in some risk factors for heart disease, the study revealed. "Substantial evidence shows that small improvements in diet greatly benefit health. Eating two to three ounces of walnuts a day as part of a healthy diet could be a good way to improve gut health and reduce the risk of heart disease," said study researcher Kristina Petersen from Penn State University in the US.

About 42 participants with overweight or obesity, between the ages of 30 and 65, were recruited for the study. Before the study began, participants were placed on an average American diet for two weeks. Followed by the "run-in" diet, participants were randomly assigned to one of three study diets, all of which consisted of less saturated fat than the run-in diet.

The diets included one that incorporated whole walnuts, one that included the same amount of alpha-linolenic acid (ALA) and polyunsaturated fatty acids without walnuts, and one that partially substituted oleic acid (another fatty acid) for the same amount of ALA found in walnuts, without any walnuts. It must be noted that in all the three diets, walnuts or vegetable oils replaced saturated fat, and all participants were made to follow each diet for six weeks with a break between diet periods.

Researchers collected fecal samples 72 hours before the participants finished the run-in diet and each of the three study diet periods. Through the sample, they analysed the bacteria in gastro-intestinal tract.

"The walnut diet enriched a number of gut bacteria that have been associated with health benefits in the past," Petersen said. "One of those is Roseburia, which has been associated with protection of the gut lining. We also saw enrichment in Eubacteria eligens and Butyricicoccus," Petersen added.

After the walnut diet, significant associations between changes in gut bacteria and risk factors for heart disease were also observed.

The researchers said that Eubacterium eligens was inversely associated with changes in several different measures of blood pressure. Greater numbers of Eubacterium eligens was linked with greater reductions in those risk factors.

How to Optimize Your Omega-6 to Omega-3 Ratio

Today, most people are eating a lot of omega-6 fatty acids.

At the same time, the consumption of animal foods that are high in omega-3s is the lowest it has ever been.

Scientists suspect that a distorted ratio of these polyunsaturated fatty acids may be one of the most damaging aspects of the Western diet.

Why Care About Omega-6 and Omega-3 Fatty Acids?

Omega-6 and omega-3 fatty acids are called polyunsaturated fats because they have many double bonds (poly=many).

Your body doesn’t have the enzymes to produce them, so you must get them from your diet.

If you don't get any from your diet, you develop a deficiency and become sick. That is why they are termed "essential" fatty acids.

However, these fatty acids are different than most other fats. They are not simply used for energy or stored, they are biologically active and have important roles in processes like blood clotting and inflammation.

But omega-6s and omega-3s don't have the same effects. Scientists believe omega-6s are pro-inflammatory, while omega-3s are anti-inflammatory.

Of course, inflammation is essential for your survival. It helps protect your body from infection and injury, but it can also cause severe damage and contribute to disease when it’s chronic or excessive.

In fact, chronic inflammation may be one of the leading drivers of the most serious modern diseases, including heart disease, metabolic syndrome, diabetes, arthritis, Alzheimer's and many types of cancer.

Scientists have hypothesized that a diet high in omega-6s but low in omega-3s increases inflammation, while a diet that includes balanced amounts of each reduces inflammation.

Those who follow a Western diet are typically eating way too much omega-6s relative to omega-3s. Many believe this is a serious health problem.

An omega-6 to omega-3 ratio that is too high may contribute to excess inflammation in the body, potentially raising the risk of various diseases.

How Much Omega-6 Did Non-Industrial Populations Eat?

According to Dr. Stephan Guyenet, typical omega-6 to omega-3 ratios for pre-industrial populations ranged from 4:1 to 1:4.

Hunter-gatherers who ate mostly land animals consumed these fats at ratios of 2:1 to 4:1, while the Inuit, who ate mostly omega-3 rich seafood, had a ratio of 1:4. Other pre-industrial populations were somewhere in between.

Anthropological evidence also suggests that the ratio human beings evolved eating was somewhere around 1:1, while the ratio today is about 16:1.

Although these populations had a lower life expectancy than modern people, some researchers estimate that chronic lifestyle diseases, such as heart disease and diabetes, were much less common.

Not only did pre-industrial populations get much less omega-6 from their diets, they also got more physical exercise, ate less sugar and didn’t have access to modern junk food.

All of these factors could explain their lower rates of modern lifestyle diseases. However, the effect cannot be solely attributed to a lower intake of omega-6 fatty acids.

People who ate a pre-industrial diet had an omega-6 to omega-3 ratio of about 4:1 to 1:4, most falling somewhere in between. The ratio today is 16:1, much higher than what people are genetically adapted to.

The Problem With the Western Diet
Western populations are eating large amounts of processed seed and vegetable oils. Some of these oils are loaded with omega-6s.

The technology to process these oils didn’t exist until about 100 years ago, and people have not had time to genetically adapt to the high amounts of omega-6.

In the graph below, you can see the dramatic increase in soybean oil consumption in the US, from zero to 24 pounds (11 kgs) per person per year. This amounted to a whopping 7% of total calories in the year 1999 .

Soybean oil is currently the biggest source of omega-6 fatty acids in the US because it is really cheap and found in all sorts of processed foods.

In the graph below, you can see how the amount of omega-6 fatty acids found in body fat stores has increased by more than 200% (3-fold) in the past 50 years alone.
 
Thus, the fats people are eating today are leading to actual changes in their bodies, both in terms of their body fat stores and cell membrane health.

A high amount of omega-6 in cell membranes is strongly associated with the risk of heart disease, which makes perfect sense given their potential pro-inflammatory effects :

However, no high-quality controlled studies have investigated the effects of omega-6 acids on heart disease .

Also, controlled studies show that linoleic acid — the most common omega-6 fatty acid — doesn’t increase levels of inflammatory markers .

In fact, it remains unclear whether a high intake of omega-6 fatty acids has any effects on the risk of chronic lifestyle diseases.

On the other hand, lots of evidence supports the positive health effects of omega-3 fatty acids. For example, their heart benefits are significant.

Omega-3s may also improve all sorts of mental disorders like depression, schizophrenia and bipolar disorder 

Nonetheless, excessive intake of polyunsaturated fatty acids, including omega-3 and omega-6, has several risks. The double bonds in the fatty acid molecules are very reactive.

They tend to react with oxygen, forming chain reactions of free radicals. These free radicals can cause cell damage, which is one of the mechanisms behind aging and the onset of cancer .

If you want to improve your ratio of omega-6 to omega-3, it’s probably a bad idea to eat a lot of omega-3 to compensate. Having a relatively low, balanced amount of each is best.

The consumption of vegetable oils high in omega-6 has increased dramatically in the past 100 years. Scientists believe this may cause serious harm.

Avoid Vegetable Oils High In Omega-6

The single most important thing you can do to reduce your omega-6 intake is avoid processed seed and vegetable oils that are high in omega-6, as well as the processed foods that contain them.

Here is a chart with some common fats and oils. Avoid all that have a high proportion of omega-6 

You can see that butter, coconut oil, lard, palm oil and olive oil are all relatively low in omega-6.

In contrast, sunflower, corn, soybean and cottonseed oils contain the highest amounts.

For more information on healthy cooking oils, read this article.

It's important to realize that benefiting from a diet low in omega-6 fatty acids is a long-term process and requires permanent lifestyle changes.

Most people store immense amounts of omega-6 fatty acids in their body fat, and it can take a while to get rid of them.

If you are concerned about omega-6 fatty acids, use vegetable oils that contain low amounts of omega-6 fatty acids, such as olive oil. Also, consider taking omega-3 supplements or eating fatty fish twice per week.

The most important thing you can do to reduce omega-6 intake is to eliminate processed vegetable oils from your diet, as well as the processed foods that contain them.

Eat Animal Foods That Are High In Omega-3

Animal foods are among the best sources of the preformed omega-3 fatty acids EPA and DHA.

One problem today is that animals are usually fed grain-based feeds containing soy and corn.

This reduces their omega-3 contents, so the polyunsaturated fats in the meat are mostly omega-6 .

Therefore, if you can afford it, grass-fed meat is definitely optimal. However, even conventionally raised meat is healthy, as long as it is not processed .

Even some conventionally raised meats like chicken and pork may be high in omega-6. If you want to decrease your omega-6 intake as much as possible, choose meats from the leaner parts of those animals.

It’s also a good idea to buy pastured or omega-3 enriched eggs, which are higher in omega-3s, compared to eggs from hens raised on grain-based feeds.

One effective way to increase your omega-3 intake is to eat seafood once or twice per week. Fatty fish like salmon are particularly good sources.

If you eat a lot of conventionally raised meats and/or don't eat much seafood, consider taking a fish oil supplement. Cod liver oil is a good choice that contains added vitamins D and A.

There are also some plant sources of omega-3, including flax and chia seeds. However, these contain a type of omega-3 called ALA. The human body is inefficient at converting ALA into the active forms — EPA and DHA .

For this reason, animal sources of omega-3s, such as fish and grass-fed animals, are usually better choices. However, vegan-friendly supplements containing EPA and DHA from algae are available.

You can increase your intake of omega-3 fatty acids by taking supplements or eating grass-fed meat or fatty fish.

The Bottom Line

Scientists suspect that a high intake of omega-6 fatty acids, relative to omega-3, may promote several chronic diseases.

However, there is still no compelling evidence to support this theory. More high-quality studies are needed to investigate the potential health effects of excessive omega-6 fat intakes.

If you are concerned, this is a simple guide to optimize your balance of the omega fats:

Avoid vegetable oils high in omega-6 (and the processed foods that contain them.
 Eat plenty of omega-3 rich animals, including something from the sea at least once or twice a week.
If needed, supplement with an omega-3 source like fish oil.

Eat right amount of good fat to stay healthy

How much one should eat to stay fit, healthy and disease-free? Consume between 20-35 percent of your calories from dietary fat, increase consumption of omega-3 fatty acids and limit the intake of saturated and trans fats, according to a research.

According to a latest paper from the US-based Academy of Nutrition and Dietetics, dietary fat for the healthy adult population should provide 20-35 percent of energy, with an increased consumption of n-3 polyunsaturated fatty acids and limited intake of saturated and trans fats.

"Nutritionists can help people understand that a total diet approach is more beneficial than simply reducing dietary fat and replacing it with carbohydrates, as a high intake of refined carbohydrate can also negatively affect health," said the study published in the Journal of the Academy of Nutrition and Dietetics.

The paper recommended a food-based approach through a diet that includes regular consumption of fatty fish, nuts and seeds, lean meats and poultry, low-fat dairy products, vegetables, fruits, whole grains and legumes.

A simple and effective way to improve health is to eat more fish, nuts and seeds and to consume fewer desserts and convenience foods, it added.

"Fat is a critical nutrient, and certain types of fat, such as omega-3s and omega-6s, are needed forgood health. For this and other health reasons, a fat-free diet is not recommended," it noted.

Fish is an excellent source of the omega-3s EPA and DHA while flax, walnuts and canola oil are good sources of ALA omega-3.

Different foods provide different types of fat. Some fats improve your health (omega-3s help your heart and brain) while some are detrimental to your health (trans fat increases heart disease risk factors), the paper said.

Eating oily fish can prevent oral and skin cancers

Omega-3 fatty acids, contained in oily fish such as salmon and trout, selectively inhibit growth and induce cell death in early and late-stage oral and skin cancers, a new study suggests.

In vitro tests showed omega-3 fatty acids induced cell death in malignant and pre-malignant cells at doses which did not affect normal cells, suggesting they have the potential to be used in both the treatment and prevention of certain skin and oral cancers.

Omega-3 polyunsaturated fatty acids cannot be made by humans in large quantities and so we must acquire them from our diet.

The scientists  were studying a particular type of cancer called squamous-cell carcinoma (SCC).

Squamous cells are the main part of the outermost layers of the skin, and SCC is one of the major forms of skin cancer.

However, squamous cells also occur in the lining of the digestive tract, lungs, and other areas of the body.   Oral squamous cell carcinomas (OSCC) are the sixth most common cancer worldwide and are difficult and very expensive to treat.
