Health Benefits of English Walnuts

Numerous health benefits are associated with eating English walnuts. They support heart health by enhancing the lipid profile, reducing inflammation, and lowering the risk of artery plaque development due to their high PUFA content, particularly omega-3 fatty acids. Additionally, the  urolithins, byproducts of walnut polyphenol breakdown by the gut flora, can have anti-cancer benefits.

Research has  shown that English walnut consumption is associated with better cognitive function and a lower risk of neurodegenerative disorders like Alzheimer’s disease. By improving the composition and functionality of the gut bacteria, these nuts can  improve gut health, which has positive effects on metabolic and weight control.

Chemical Composition of English Walnuts

The nutritional value of English walnuts is highly regarded. They contain a plethora of vital macro- and micronutrients, which contribute to their properties that support good health. Proteins, dietary fiber, and healthy fats—primarily polyunsaturated fatty acids (PUFAs), especially alpha-linolenic acid (ALA), an omega-3 fatty acid—are included in the macronutrients. One of the few plant-based sources of omega-3 fatty acids, which are crucial for optimum human health, are English walnuts.

These nuts are loaded with minerals like magnesium, copper, and manganese, as well as vitamins like vitamins E and B.  They are also abundant in vitamins such as folates, riboflavin, and thiamine. English walnuts  contain a variety of bioactive substances, including phytosterols, flavonoids, and polyphenols, along with  ellagitannins and ellagic acid, which are substances with anti-inflammatory and antioxidant activities.

Physiological Properties of English Walnuts

English walnuts have a variety of physiological effects. The body transforms the high ALA content of these foods into the longer-chain omega-3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), which are essential for preserving cellular membrane integrity, decreasing inflammation, and promoting heart and brain health.

The gut bacteria convert the polyphenols, mostly ellagitannins, into urolithins. The antioxidant, anti-inflammatory, and anti-proliferative properties of urolithins protect against numerous disorders, including cancer and heart disease. English walnuts contain phytosterols, which compete with cholesterol for absorption in the digestive system and lower blood cholesterol levels.

Optimal Dosage of English Walnuts

Although there is no established dose for the consumption of English walnuts, the American Heart Association  advises consuming 42.5 grams (or 1.5 ounces) of nuts daily, or around a handful of walnuts. This amount is thought to offer enough nutrients to promote health without adding too many calories to your diet.

Side Effects

English walnuts are often well accepted by our body, however ,due to their high fiber content, frequently eating them can cause digestive distress. They can also cause allergies in some sensitive people, which can range in severity from moderate to severe as with all nut products.

Potential Substance Interactions of English Walnuts

Scientific research has no reports of any major drug interactions associated with English walnuts. However, if you are  using anticoagulant medicines, you  should use caution while consuming walnuts due to their high PUFA content, particularly omega-3 fatty acids, which can enhance the effects of these medications.

Responsible Use

With their outstanding nutritional profile and various health advantages, English walnuts are a beneficial supplement to a balanced diet. It is  important to eat them sensibly, taking your  unique health conditions into consideration, keeping an eye out for any allergic responses, and assessing their calorie content in relation to your entire food intake.

Future studies will investigate  potential contraindications or drug interactions and  validate these advantages in more extensive clinical trials. English walnuts should, like all foods, be a component of a balanced diet and a healthy way of life.
