Dietician says these 4 foods are non-negotiable for good health

It’s easy to get lost in waves of this diet and that superfood, and still end up deficient in . But some foods are foundational: they reliably deliver fiber, vitamins, minerals, and bioactive compounds in forms our bodies recognize and use.

Registered dietitian Shyla Cadogan recently distilled her daily essentials into the acronym BBEG—Berries – Beans – Eggs – Greens—as four foods she considers indispensable for long-term health. In her October 14 Instagram video, she explained why each of these foods deserves a permanent place on your plate.



Scientific literature backs up the importance of such core food groups. For instance, diets rich in vegetables, legumes, and fiber-associated foods show reduced risks of chronic disease and support gut health. Below are the four non-negotiables, as per Cadogan

Berries

Cadogan encourages daily berry consumption—whether raspberries, blackberries, or blueberries (she favors wild blueberries, which she claims have double the antioxidant capacity). Berries are rich in polyphenols, anthocyanins, vitamin C, and fiber, giving them potent antioxidant and anti-inflammatory potential. They are frequently cited in dietary patterns (like MIND or Mediterranean) for brain and cardiovascular protection.

Beans (legumes)

Cadogan suggests adding a serving of beans daily to boost fiber and cover nutrient gaps. She specifically notes that cooking and then cooling beans increases resistant starch type 3 (RS3), which ferments in deeper parts of the colon and supports gut health. Legumes are a core part of healthy dietary patterns, contributing plant protein, fiber, folate, magnesium, and more. They help regulate blood sugar, lower LDL cholesterol, and support gut microbiome health.

Eggs

Cadogan emphasizes that eggs are nutrient-dense: they supply choline (important for brain health), complete protein, healthy fats, and a range of vitamins and minerals. Eggs provide a "complete" protein with all essential amino acids, and choline is relatively scarce in many diets. They also carry fat-soluble vitamins and carotenoids (when eggs are from hens fed well). Because eggs are so nutrient-dense per calorie, they’re useful especially in restricted diets.

They also carry fat-soluble vitamins and carotenoids (when eggs are from hens fed well).

Greens (leafy & cruciferous vegetables)

Cadogan advises consuming greens daily, ideally multiple times, including leafy and cruciferous varieties. She points to their fiber, vitamins, minerals, and antioxidant strength. Vegetables—especially dark greens—are foundational in virtually all healthy diet indices. They provide micronutrients (vitamins A, K, folate, minerals), fiber, and phytonutrients (e.g. glucosinolates in cruciferous types) that support detoxification and reduce cancer risk. Raw, cooked, steamed—mix it up, as different preparations release different compounds. Some greens (like spinach) are high in oxalates—if you have kidney stone history, balance intake with low-oxalate greens.
