Those who want to eat healthily and do a bit of research on the subject will sooner or later come across the term “superfoods”. Whether avocados, acai berries or chia seeds, many foods are promoted as true nutritional powerhouses. But what exactly is behind this trend?
In fact, there are many foods that contain particularly high amounts of vitamins, minerals, antioxidants or healthy fatty acids. They can be a valuable addition to a balanced diet and help provide the body with important nutrients.
This article takes a closer look at what superfoods actually are and presents 10 superfoods that are an ideal addition to a healthy lifestyle.
What are superfoods?
The term “superfood” is neither legally defined nor protected. It generally refers to foods that contain particularly high amounts of valuable nutrients compared to other foods.
Superfoods are not necessarily exotic. Although many nutrient-rich foods such as goji berries, spirulina or moringa come from other continents, everyday foods such as almonds, blueberries and broccoli can also be classified as superfoods.
Typical characteristics of superfoods include:
- High levels of vitamins and minerals
- Rich in antioxidants
- Contain healthy fatty acids
- Good source of fibre
- High nutrient density with comparatively few calories
It is important to understand that a single food cannot compensate for an unhealthy diet. Superfoods work best as part of a varied and balanced diet.
10 superfoods and their properties at a glance
Not every superfood provides the same health benefits. While some foods stand out because of their high levels of vitamins and antioxidants, others are valued for their healthy fats, fibre or plant-based protein. The following overview presents some of the healthiest foods and highlights the special properties that make them valuable components of a balanced diet.
Extra virgin olive oil
Extra virgin olive oil is a key component of the Mediterranean diet and has long found its way into kitchens around the world. Besides its intensely fruity flavour, it is particularly appreciated for its health benefits.
Extra virgin olive oil is cold-pressed using a mechanical process, which helps preserve its valuable compounds. This “green gold” is characterised by a high content of unsaturated fatty acids. These are known to support healthy cholesterol levels and have a positive effect on heart health. In addition, olive oil is rich in antioxidants such as polyphenols, which protect cells from free radicals. They also have strong anti-inflammatory properties.
Chiaseeds
Originally from South America, chia seeds are among the most nutrient-dense seeds available. They provide:
- Omega-3 fatty acids
- Plant-based protein
- Calcium
- Magnesium
- Fibre
One of their most remarkable characteristics is their ability to absorb many times their own weight in liquid. As a result, the seeds expand and promote a long-lasting feeling of fullness.
Avocado
With its high content of monounsaturated fatty acids, avocado is particularly popular in vegan diets. It is also rich in vitamins K and E, folate, potassium and fibre. These valuable nutrients play an important role in maintaining heart health.
Due to its high fat content, avocado provides lasting satiety and represents a healthy source of fat.
Broccoli
This familiar vegetable is available in almost every supermarket. It is hardly surprising that broccoli is considered healthy, as it is one of the healthiest vegetables of all.
It contains:
- Vitamin C
- Vitamin K
- Folate
- Potassium
- Fibre
In addition, broccoli provides phytochemicals such as sulforaphane, which offer strong protection for the body’s cells.
Gojiberries
Goji berries are usually sold dried. These small red berries originate from China, which is also where their name comes from. “Goji” means “happiness” in Chinese.
In recent years, goji berries have become popular in many countries as an exceptional superfood. This is mainly due to their high content of vitamins C and A, antioxidants, calcium and iron. These nutrients help protect cells from free radicals, have anti-inflammatory properties and support oxygen transport in the blood.
Walnuts
Walnuts are particularly popular during the Christmas season as a healthy and flavourful snack. Compared with other nuts, they have the highest content of omega-3 fatty acids. They are also packed with vitamins A, B, C and E, antioxidants and valuable minerals such as calcium, magnesium, potassium, iron and phosphorus.
However, walnuts are also very high in fat. Despite their many vitamins and minerals, they should therefore be consumed in moderation. As a rule of thumb, a handful of walnuts per day is an ideal addition to a balanced diet.
Oats
Oats are available almost everywhere and are very inexpensive. For this reason, they are often underestimated as a superfood. However, they are a highly nutritious addition to a healthy lifestyle. This is mainly due to their valuable nutrients:
- High-quality fibre
- Plant-based protein
- Iron
- Magnesium
- Zinc
Particularly valuable are the so-called beta-glucans. These plant fibres can help positively influence cholesterol levels and provide long-lasting satiety.
Salmon
Salmon is considered particularly valuable because of its high content of omega-3 fatty acids.
Its most important nutrients include:
- Omega-3 fatty acids EPA and DHA
- High-quality protein
- Vitamin D
- Vitamin B12
- Selenium
Omega-3 fatty acids play an important role in heart health, brain function and numerous metabolic processes. Just one or two meals containing salmon per week can make a valuable contribution to nutrient intake.
Turmeric
Turmeric is one of the best-known spices in traditional Asian cuisine. Its most important compounds include:
- Curcumin
- Antioxidants
- Essential oils
- Manganese
- Iron
Curcumin in particular has been the subject of scientific research. It possesses antioxidant properties and may help protect cells against oxidative stress.
Spinach
Spinach is another vegetable that can be classified as a superfood. Thanks to its high levels of iron, vitamins K and C, magnesium and folate, it is considered a true nutritional powerhouse.
In addition, spinach contains numerous phytochemicals that contribute to overall health.
