Lamb and chickpeas cover zinc and fermentable fiber — the latter backed by the Lancet's landmark fiber series — while harissa, turmeric and garlic do the flavor lifting in a slow, brick-red braise.

Lamb is one of the most reliable dietary zinc sources, and the zinc in red meat is absorbed considerably better than the zinc in grains and legumes, where phytates get in the way. Why care? Zinc deficiency measurably impairs immune cell function — the foundational work on human zinc deficiency and immunity laid this out decades ago (Molecular Medicine, 2008) — and older adults are among the groups most likely to run low. None of which makes lamb a supplement; it makes it a dense, bioavailable food source, which is usually the better deal anyway.
The chickpeas may quietly be the healthiest thing in the pot. The Lancet's landmark series of systematic reviews and meta-analyses on carbohydrate quality found that people eating the most fiber — with legumes among the best-performing sources — had 15 to 30 percent reductions in all-cause mortality, coronary heart disease and type 2 diabetes incidence (Lancet, 2019), with supporting randomized-trial data on weight and cholesterol. The spices ride along with weaker but real literatures: black pepper's piperine boosts absorption of turmeric's curcumin roughly twenty-fold (Planta Medica, 1998), and garlic preparations lower blood pressure in hypertensive adults in meta-analysis (Journal of Nutrition, 2016) — both findings from doses well above what one serving of tagine provides.
Lamb shoulder brings the zinc plus the collagen that a two-hour braise converts into body. Chickpeas supply the fermentable fiber your gut bacteria actually use, alongside plant protein. Turmeric plus the black pepper already in the pot covers the curcumin-piperine pairing; garlic, crushed and rested before it is fried, brings the allicin. Harissa and dried apricots pull the dish between heat and sweetness, and almonds finish it with crunch and a little extra magnesium.

Serves 4–6, ideally with flatbread or couscous. Like most braises it improves overnight as the spices settle in.
