Most people assume that eating for long-term health means overhauling their entire diet, investing in expensive supplements, or following elaborate meal plans that require hours of preparation. Dr. Amir Khan, a general practitioner who regularly shares evidence-based health advice on his Instagram, suggests the reality can be considerably simpler. He has been drawing attention to two common, inexpensive foods that carry a surprisingly powerful combination of nutrients linked to reduced risk of heart disease and certain types of cancer. Neither requires a trip to a specialty grocery store. One is a vegetable most people already keep in their refrigerator, and the other is a breakfast staple that has been sitting quietly in pantries for decades.
The first food Dr. Khan highlights is carrots. What makes them particularly valuable from a health standpoint is not just one compound but the layered interaction of several. Carrots are rich in pectin, a type of soluble fiber that performs two useful functions simultaneously: it feeds the beneficial bacteria living in the gut, and it slows the rate at which sugar and cholesterol are absorbed through the intestinal wall. Both of these effects have meaningful downstream consequences for metabolic health, cardiovascular function, and the inflammatory environment of the body. But the headline nutrient in carrots, according to Dr. Khan, is beta-carotene, the powerful antioxidant responsible for their distinctive orange color.
The body converts beta-carotene into vitamin A, which supports both healthy vision and a well-functioning immune system. Beyond those well-known roles, beta-carotene has been specifically linked in research to a reduced risk of heart disease and certain cancers, making it one of the more clinically significant antioxidants found in everyday food. Dr. Khan recommends eating carrots as a snack paired with hummus, a combination that also adds protein and healthy fats to the mix. For those who want to incorporate more carrots into their diet in other ways, they work well added to salads, stews, and casseroles, or blended into a smooth cream soup that preserves most of their nutritional value.

The second food Dr. Khan recommends is oats, and the case for them is equally compelling. “Oats are full of antioxidants and beneficial plant compounds called polyphenols,” he explains. What makes oats particularly distinctive in the world of whole grains is that they contain a specific antioxidant found almost nowhere else in nature, called avenanthramide. This compound does something rather remarkable: it stimulates the production of nitric oxide molecules in the body, which help relax and widen blood vessels, a mechanism that can directly contribute to lower blood pressure over time. The cardiovascular implications of that effect alone would make oats worth eating regularly, but avenanthramide has an additional benefit that tends to surprise people. It also has anti-inflammatory properties, which means it can help relieve itchy or irritated skin, a connection between diet and dermatology that most people never think about.
Oats are also an excellent source of beta-glucan, a well-studied form of soluble dietary fiber with a strong track record in clinical research. Beta-glucan has been shown to meaningfully reduce LDL cholesterol levels, the type associated with increased cardiovascular risk, which is one of the primary reasons oats appear so frequently in dietary guidelines for heart health. Some research also indicates that regular oat consumption supports healthy digestion and can help address constipation, making a morning bowl of oatmeal one of the more efficient single-food choices available for anyone looking to cover multiple health bases simultaneously.
What is striking about both of Dr. Khan’s recommendations is how far they are from anything exotic or trend-driven. Carrots and oats are among the most widely available, affordable, and shelf-stable foods in any grocery store, and yet their health credentials are backed by decades of research. In a wellness landscape dominated by expensive supplements, proprietary blends, and constantly rotating superfoods, there is something genuinely useful about a practicing physician pointing back to the basics. Pairing either food with other nutrient-dense ingredients, the way Dr. Khan suggests doing with carrots and hummus, amplifies their benefits without adding complexity.
Beta-carotene is actually fat-soluble, which means the body absorbs significantly more of it when carrots are eaten alongside a small amount of fat, so pairing them with hummus or a drizzle of olive oil is not just a flavor choice but a genuinely smarter nutritional strategy. Avenanthramide, the unique antioxidant in oats, is also what makes colloidal oatmeal so effective as a topical skin treatment in lotions and creams for conditions like eczema and poison ivy rash, which means the same compound that helps your blood vessels works from the outside in as well. And carrots were not always orange: until the 17th century, most cultivated carrots were purple, yellow, or white, and the orange variety was selectively bred in the Netherlands, reportedly as a tribute to the Dutch royal House of Orange.
