Sunflower Seeds: Benefits, Calories, and the Salt Problem

Sunflower seeds are a staple snack in Vietnam, especially at Tet, when a bowl of them sits on almost every table. They are genuinely nutritious, and one of the best food sources of vitamin E. The catch is in how they are usually sold: roasted in the shell with a lot of salt. Here is the full picture.

The numbers

Per 28g of kernels (shelled): roughly 165 calories, 5.5g protein, 2.4g fibre, 14g fat, mostly unsaturated.

The standout is vitamin E. A 28g serving covers close to half of the daily need, more than almost any other common food. Sunflower seeds also provide selenium, magnesium and B vitamins.

What they are good for

Vitamin E. An antioxidant that helps protect cells. Sunflower seeds and almonds are the two easiest ways to get it from food.

Healthy fat and plant protein. Like pumpkin seeds, they add filling protein and unsaturated fat to a snack or a meal.

Selenium and magnesium. Two minerals many diets fall short on.

The salt problem

This is the part that matters for how most people eat them. The roasted, in-shell sunflower seeds sold for Tet are usually heavily salted, and the salt sits on the shell, so you take it in every time you crack one with your teeth. Over an afternoon of snacking that adds up to a lot of sodium.

Three simple fixes: - Choose unsalted or lightly salted packs, and check sodium on the label. - Buy shelled kernels for everyday use; they are easier to portion and add to food. - Portion them out rather than eating from a large bowl, which is where the hours of grazing happen.

How to eat them

• Portion: about 28g of kernels, roughly 165 calories.
• Add to food: scatter on salads, stir into oat porridge or yogurt, or add to a trail mix.
• Storage: the oils in sunflower seeds turn rancid if left warm and open. Keep them airtight and cool.

Who should take care

• Anyone watching salt or blood pressure: choose unsalted.
• Kidney patients on restricted diets should check with their doctor, as seeds contribute phosphorus and potassium.
• Seed allergy: rare, but avoid if you react.
