Nuts offer numerous health benefits, from supporting a healthy heart to potentially protecting against cancer – find out which nut is packed full of calcium, which has the lowest fat and calorie content and which makes the perfect addition to a plant-focused diet.

What are nuts?

Nuts are nutrient dense, edible seed kernels encased in a hard shell; and include almonds, hazelnuts, walnuts and pistachios, as well as cashews, pine nuts, pecans, macadamias and Brazil nuts. Although chestnuts (Castanea sativa) are tree nuts, they differ from the other common varieties because they are starchier and lower in fat. Often thought of as a ‘nut,’ peanuts are technically legumes, just like peas and beans.

Top 10 healthiest nuts

1. Almonds

Sweet tasting almonds have a number of health benefits.

A 30g serving of almonds provides:

  • 184 kcals/760 kJ
  • 6.3g protein
  • 16.7g fat
  • 1.3g saturated fat
  • 11.5g mono-unsaturated fat
  • 3.1g poly-unsaturated fat
  • 2.1g carbohydrates
  • 2.2g fibre
  • 72mg calcium
  • 81mg magnesium
  • 7.19mg vitamin E
  • 14mcg folate

Packed with heart-friendly monounsaturated fat, fibre and vitamin E, almonds have the highest calcium content of a nut – we need this mineral for robust bones, as well as for the correct function of our nerves and muscles. The beneficial fat and high fibre content of almonds means they help to manage cholesterol levels for heart health.

Eating skin-on almonds may provide even greater benefits; supporting gut health by promoting the growth of beneficial strains of bacteria, including Lactobacillus and Bifido-bacteria. The skin is also full of protective compounds called flavonoids which have antioxidant benefits.

Selenium is a mineral that acts as a protective antioxidant, it supports immunity and helps wounds heal. You only need one to three Brazil nuts a day to get all the selenium you require, because we only need this mineral in very small amounts. Also containing vitamin E and the polyphenols ellagic and gallic acid, Brazil nuts enhance our defence mechanisms and help regulate blood lipids.

Eating walnuts appears to not only benefit us but our gut bacteria too, this was seen in an eight week study which followed 194 healthy adults who consumed 43g of walnuts each day. The findings showed an increase in the number of beneficial gut bacteria and especially in those that produce the short chain fatty acid butyrate, which among other benefits has anti-inflammatory and anti-cancer properties.
