Dr. Marvin Singh’s Top 10 Foods for Gut Health

Marvin Singh, MDI advise my patients that adhering to a healthy diet is one of the main lifestyle choices that they can make to improve gut health. A gut-healthy diet doesn’t need to be complicated. There are many gut-healthy foods out there that most people should be able to easily integrate into their diet. These foods are rich in a combination of nutrients like antioxidants, vitamins, minerals, polyphenols, and omega-3s. Here are my 10 favorite foods for gut health:

  1. Arugula

A member of the bitter greens family, arugula is loaded with calcium, potassium, folate, and a host of other vitamins and minerals. Arugula is also a cruciferous vegetable, which means it’s packed with fiber and prebiotic material to sustain gut health. Arugula adds a flair of spice to foods. You can put it in a salad or mix it with your favorite dish.

  1. Cilantro

Considered a super-herb by some health experts, cilantro has the ability to support detoxification and balance blood sugar. Cilantro is chock-full of immune-supporting antioxidants, like vitamin C, vitamin A, and quercetin. You can add this flavorful herb as a garnish to a salad or any kind of dish.

  1. Asparagus

Asparagus is a prebiotic-rich food, which means it provides nourishment for beneficial gut bacteria. This vegetable is also one of the few dietary sources of glutathione, an antioxidant concentrated in the liver that helps remove waste from the body. You can grill, sauté, or steam asparagus, or even add it chopped to a salad.

  1. Bok Choy

A cruciferous vegetable, bok choy contains gut-healthy vitamins and minerals and is a good source of manganese, folate, and sulforaphane. Sulforaphane activates the protein Nfr2, which in turn activates certain antioxidant genes in the body.

  1. Ginger

Ginger’s anti-inflammatory and antioxidant properties make it a potent digestive aid that people have used for centuries to improve gastrointestinal comfort. In addition to easing nausea, ginger can be used to alleviate gas, bloating, and stomach pains.

  1. Kimchi

A staple of Korean cuisine, kimchi is a side dish of salted and fermented vegetables like napa cabbage and Korean radish, prepared with healthy seasonings like spring onions, garlic, ginger, and chili powder. Fermented foods like kimchi help to modulate the body’s immune system and inflammatory pathways.

  1. Okinawan sweet potato

Okinawan sweet potatoes, which have a rich purple color, contain a high amount of antioxidants. In fact, they have more antioxidants than blueberries, and in test-tube studies, antioxidants in purple sweet potatoes were shown to aid in the growth of a specific type of beneficial gut bacteria.

  1. Blueberries

Blueberries contain blue-purple pigments called proanthocyanidins that are superb for brain health. Blueberries are also packed with fiber—about 6 grams per cup.

  1. Turmeric

This flavorful, golden spice inhibits the production of pro-inflammatory genes and blocks the inflammatory response pathway, which leads to several full-body benefits, from supporting immunity to promoting gut comfort.

  1. Walnut

Walnuts are a good source of vitamin E and contain polyphenols, a category of plant compounds that offers various health benefits and are thought to boost digestion and brain health, as well as protect against heart disease, type 2 diabetes, and even certain cancers. Aside from their rich nutritional profile, walnuts are versatile. You can eat them as a snack, or toss them in a salad.

Patient Care Is Our Priority

Medical organizations throughout North America understand that our rigorous certification standards prove that ABPS Diplomates are capable of delivering the best patient care possible.

Far too often, medicine is led by less than 5% of non-practicing physicians taking away and replacing the voice of the 95% of physicians practicing and placing patient safety and care first on the front lines every day. The American Board of Physician Specialties has raised the standards in physician board certification not only in the quality of their boards of certification, but in hearing and allowing for the voice of those active physicians caring directly for patients. Having been a part of the ABPS over the last 28 years has allowed me to grow as a woman leader in a field often wrought with challenges. It helped me and others raise the bar of the standards of care in my specialty, Emergency Medicine, through their Board Certification in Emergency Medicine (BCEM). ABPS also helped raise the standards of care for 21st century medicine through their certifications in other specialties, particularly in Integrative Medicine & Disaster Medicine. Having physician voices heard matters to medicine and is essential in the betterment of patient safety and care.

On October 18, 2007, President George W. Bush released Homeland Security Presidential Directive 21 (HSPD-21), calling on our nation, among other initiatives, to “collectively support and facilitate the establishment of a discipline of disaster health”. It is a great testament to the wisdom and foresight of the American Board of Physician Specialties that it immediately set to work and created, within the short span of only one year, an educational blueprint and set of certification examinations, both written and oral, for a new subspecialty of disaster medicine—and it is why I chose to be part this vital initiative and this wonderful organization. This is but one of the many innovative programs initiated by the American Board of Physician Specialties over the years, and why I am proud to support its work on behalf of our nation’s public health.

When the American Board of Physician Specialties offered to host the American Board of Integrative Medicine, ABPS became a landmark organization working to move medicine into the twenty first century. Certifying physicians who have completed rigorous academic training in Integrative Medicine ensures that the field of Integrative Medicine will continue to develop academically, clinically, and professionally. The leadership of ABPS continues to impress me - they are diligent in constantly innovating to provide certifications for physicians who want to advance their careers and their areas of expertise. I am honored to be a part of this organization.

There are many ways board certification advances a physician career. ABPS Board examination verifies your accuracy, precision, and reflects your mastery of your residency training verifying your expertise. ABPS Board certification demonstrates your level of expertise beyond your practice experience, primary education degrees, and training which are necessary for insurance reimbursement and practice privilege requirements. Attaining your ABPS Board Certification will clarify your purpose, secure your practice growth, and expand into leadership positions. Board certification can serve as an indication of a physician’s commitment to medicine, beyond the minimal standards and competency of training, their measurement to quality of care, and attaining an award for excellence.

When I think historically, advancement in medicine and patient safety and care has been driven by the diversity of people and scientific thought. That’s what I found at the ABPS and more. For over 60 years that is just who we are. I found a physician certifying body that provides a choice and voice to all physicians ensuring that patients are always placed first.

When I decided to pursue a full time role as a physician executive it was important to me to obtain additional professional training, education and work experience. Board certification through the ABPS in Administrative Medicine is validation of my efforts and a demonstration of dedication to professional development. We need more physicians to become full time health care executives, knowing there is a board certification option in Administrative Medicine encourages physicians to take the leap from full time clinical practice to healthcare organizational leadership.

Richard Paula, MD
Administrative Medicine
The American Board of Physician Specialties has provided me with the opportunity to demonstrate mastery of internal medicine through board certification. As a hospitalist, board certification is an expected credential, and hospitals recognize the American Board of Physician Specialties (ABPS) as one of the three standard credentialling bodies for Internal Medicine. Additionally, the ABPS has helped me develop leadership skills as a Board member and Committee Chairperson. ABPS has also helped me sharpen critical thinking skills as a test question developer and reviewer. The Allopathic (MD) and Osteopathic (DO) physicians in the ABPS are lifelong learners and frequently pursue multiple board certifications. I enjoy the camaraderie of my peers in ABPS.
