Bone Broth: The Ancient Remedy That Science Now Confirms Works

LAGOS — Bone broth has been a staple of Nigerian cooking for generations. From nkwobi and isi ewu in the east, to ofe onugbu and pepper soup across the country, Nigerians have long simmered bones and connective tissue into rich, nourishing broths. Now science is confirming what grandmothers always knew: bone broth is genuinely good for you.

A growing body of research highlights the health benefits of regularly consuming bone broth. It is rich in collagen, glycine, proline, and minerals including calcium, magnesium, and phosphorus. Each of these nutrients plays an important role in maintaining healthy joints, bones, skin, and digestion.

Nutritionist Dr. Chioma Obi explained the core benefits in an interview published this week. She said bone broth is one of the most nutrient-dense foods available, particularly for people who cannot afford expensive supplements. “It is cheap, it is natural, and it is everywhere in Nigerian cooking. We just need to understand what it is doing for us,” Obi said.

One of the most significant benefits is for joint health. The collagen in bone broth breaks down into gelatin during cooking, which provides amino acids that the body uses to maintain cartilage in joints. Regular consumption has been associated with reduced joint pain, particularly in people with arthritis or high-impact lifestyles.

Gut Health and Digestion

Bone broth is also rich in gelatin, which supports the lining of the digestive tract. People with digestive disorders including irritable bowel syndrome have reported improvement after incorporating bone broth into their diets regularly. The glycine in broth also supports the production of stomach acid, which improves nutrient absorption.

In addition, bone broth supports better sleep. Glycine has been shown in clinical studies to improve sleep quality when consumed before bedtime. It reduces core body temperature slightly and helps regulate the sleep-wake cycle. A bowl of pepper soup in the evening may be more than just comfort food.

Furthermore, bone broth contains glutamine, an amino acid that supports immune function. During periods of illness or high physical stress, the body’s demand for glutamine increases significantly. Bone broth provides a readily available source that is easy to absorb even when appetite is low.

How to Get the Most From Bone Broth

Dr. Obi said the key to nutritious bone broth is long, slow cooking. The longer the bones simmer, the more nutrients are extracted from the marrow and connective tissue. She recommends simmering bones for a minimum of six hours, with twelve hours producing an even richer broth.

Adding a splash of vinegar, even a small amount of palm wine vinegar, helps draw minerals out of the bones during cooking. Onions, garlic, uziza leaves, and other traditional Nigerian additions not only improve flavour but add their own nutritional benefits to the final product.

For Nigerians managing arthritis, joint pain, digestive problems, or sleep difficulties, Dr. Obi recommends incorporating bone broth into the diet two to three times per week. She said it is one of the most affordable and culturally appropriate health interventions available to Nigerians across all income levels.
