Selenium is the single most critical mineral for thyroid function, and most Indians are deficient in it — Indian soils are selenium-poor, which means our vegetables and grains carry very little. The thyroid gland has the highest selenium concentration of any organ in the body because selenium is needed to convert inactive T4 into active T3. Without enough of it, even people taking levothyroxine may continue to feel sluggish because the conversion isn't happening properly. Here's the remarkable part: just 2 Brazil nuts provide the entire daily selenium requirement (55-70mcg).
This salad combines Brazil nuts with pumpkin seeds (zinc for thyroid receptor function), sunflower seeds, iron-rich spinach, and a simple lemon-olive oil dressing. It takes 10 minutes, needs no cooking, and all the selenium and Vitamin C stay fully intact. Assemble it at breakfast and eat it at lunch — it holds well for a few hours undressed.
Ingredients
How to Make It
Wash the spinach leaves thoroughly and tear into bite-sized pieces. Pat dry or use a salad spinner — wet leaves dilute the dressing and make everything watery.
Roughly chop the Brazil nuts into chunky pieces. Don't powder them; keeping them chunky is better for texture and you'll enjoy the meal more. If using raw pumpkin seeds, dry roast them for 2 minutes in a pan — the flavour improves noticeably.
Slice cucumber into half-moons. Halve the tomatoes. Grate the raw beetroot on the coarse side of a grater.
Whisk together lemon juice, olive oil, rock salt, black pepper, and jeera powder in a small bowl to make the dressing.
In a large salad bowl, combine the spinach, cucumber, tomatoes, and grated beetroot. Toss gently.
Pour the dressing over the salad and toss to coat everything evenly.
Scatter the chopped Brazil nuts, pumpkin seeds, and sunflower seeds on top just before serving — adding them before dressing makes them soggy.
Serve immediately. Once dressed, this salad doesn't keep well — make it fresh and eat it fresh.

Health Benefits
The selenium in Brazil nuts (68-91mcg per nut) directly supports the conversion of T4 to T3 — the active thyroid hormone that drives metabolism, energy, and temperature regulation. Without adequate selenium, hydrogen peroxide accumulates in thyroid cells, accelerating the destruction seen in Hashimoto's. Clinical trials show selenium supplementation reduces thyroid antibody levels (TPO-Ab) by 21-40% in Hashimoto's patients. Zinc in pumpkin seeds supports thyroid hormone synthesis and binding. Beetroot contains nitrates that improve blood flow, and spinach provides iron — though those with hypothyroidism should cook spinach rather than eat it raw to reduce its mild goitrogenic effect.
Pro Tips
- →Strictly limit Brazil nuts to 2-4 per day. They're extraordinary for selenium, but eating 10 or more daily can cause selenium toxicity — hair loss and nerve damage are the symptoms, ironically the same as thyroid disease. Two nuts is all you need.
- →Use freshly squeezed lemon juice, not bottled — pasteurisation destroys most of the Vitamin C in commercial bottled juice.
- →If you have Hashimoto's, consider lightly steaming the spinach before adding to the salad. Cooking reduces goitrogens by 30-40% for people with autoimmune thyroid conditions.
- →This salad is best at lunch, not dinner — raw fibre is easier on digestion when your digestive system is most active.
Variations
- 1Add 1 boiled egg to each serving for additional selenium (14mcg per egg) and complete protein — a simple upgrade that makes this a full meal.
- 2Replace spinach with rocket (arugula) or watercress for a peppery flavour with equally strong thyroid-supportive micronutrients.
- 3Add ¼ avocado for healthy monounsaturated fat that improves absorption of fat-soluble nutrients.
