Hanfsamen im All – Geschälte Hanfnüsse als Snack für Astronauten!

Gestern erreichte uns aus Kanada, von der jährlichen Konferenz der Canadian hemp trade association (CHTA), eine bahnbrechende Neuigkeiten.
Der kanadische Astronaut und Commander, der im Dezember startenden sechs monatigen ISS Mission, Chris Hadfield, wird geschälte Hanfsamen als Snack mit ins All nehmen.
Genauer gesagt handelt es sich um das kanadische Produkt “Holy Crap“. Dieses besteht aus einer Mischung von geschälten Hanfnüssen, Chia Samen, Buchweizen, Cranberries, kleinen Apfelstückchen und Zimt. Alle Zutaten stammen aus kontrolliert biologischem Anbau.
Damit ein Produkt überhaupt als “Astronautennahrung” geeignet ist, muss es verschiedene Kriterien erfüllen. Neben der Haltbarkeit von mindestens einem Jahr, ist es besonders wichtig, dass es den Körper mit wichtigen Nährstoffen versorgt, um die Astronauten bei ihrer harten Arbeit im Orbit bei Kräften zu halten.
Was könnte da besser geeignet sein als, als eine Mischung mit Hanfsamen. Das perfekte Verhältnis von Omega-3 und Omega-6 Fettsäuren stärkt Körper und Geist, Proteine geben Energie für den Tag.
Ein weiterer Vorteil von Hanfnüssen ist, dass sie glutenfrei und vegan sind, keine der üblichen Nussallergene enthalten und roh verzehrt werden können.
Nicht nur für Astronauten im All, sondern auch für uns “Erdlinge” das perfekte Lebensmittel.
Hier der Originaltext der Presseerklärung:

The world’s most amazing breakfast cereal
Wins a spot on the International Space Station

The Canadian Space Agency announced on August 28th that Hapi
Foods cereal, will be shipped in December 2012 to the International
Space Station with Canadian Astronaut and Mission Commander
Chris Had­eld where he will live and work for six months as part of
the crew of Expedition 34/35.

Food in space

Provisions delivered to the ISS need to meet a number of criteria, to
ensure that it is safe for astronauts to consume while on orbit. There
are no refrigeration or freezer capabilities on the ISS therefore food
needs to have a shelf-life of at least one year. Commercially available
products have undergone shelf-life testing and food processing
facilities use various safety and quality assurance programs to ensure
commercially available items are safe for consumption. “On a
long-duration space mission, snacks can be a great morale booster,”
said Had­eld. “Sharing this food will not only lift our spirits, but it
will also give me the chance to tell the crew a little bit about the
diversity and richness of the natural and cultural landscapes of Canada.”

Approximately one year before launch, Had­eld met with NASA and CSA
nutrition experts to determine his space menu. Together they reviewed
personal preferences and nutritional value requirements for a hard day’s
work in orbit. Just like on Earth, astronauts eat three times a day and
have one or two snacks daily.

The organic breakfast cereal phenomenon provides:

More energy
Plant-based protein carries you through to lunch

Increased concentration
Perfect ratio of omega -3 and -6 fuels your brain

Stabilized blood sugar
Soluble and insoluble ­bers slow down the metabolism of starch in your body

• Energy intake is often 30-40% below WHO recommendations.

• Often there are negative changes in overall nutrition status during a flight.

• Space environment results in physiological changes that can alter nutritional status

• The diets of crew members are not taken lightly. Dietitians plan meals
and every variable is tested to make sure that the meal plan is as ideal
as possible.

• Even with every possible measure put into place, body weight, total
bone mineral content, and bone mineral density decreased during the
flight. Vitamin D concentration in crew bone was decreased, and bone
re-absorption increased, by long exposure to microgravity. Antioxidant
capacity decreased during flight, leading to increased susceptibility to
genetic damage from radiation.


• Another challenge that the HRP must work to overcome is developing
shelf-stable food products that require minimal effort to prepare and
offer crew members an enjoyable eating experience. As future missions
require longer stays in space, food scientists expect the issues of
space food shelf life and palatability to receive more research


• Although the menu of crew members has come a long way, they are still
faced with a number of obstacles to having appetizing and nutritious meals.

• Astronauts usually loose weight during spaceflight so having foods
that are dense in energy and nutrients is important as extra stressors
are added to the body during flight.

• Because “space food” must, for the most part, be shelf stable there
are many methods of processing and preservation applied to foods brought
on board. There are some fresh, refrigerated, frozen and natural form
foods brought (foods that would be more nutritionally beneficial) but
there is also rehydratable foods, thermostabilized foods, intermediate
moisture foods and irradiated foods.

Many of the processing methods used to create a shelf stable product
will greatly decrease the quality and quantity of nutrients present in
food. With the astronauts being under increased nutritional need during
their missions they need foods that will not only be shelf stable and
easy to travel with but also exceptionally high in calories and
essential nutrients. Holy Crap is unprocessed in any way and also shelf
stable, easy to pack and hydrate, and created with some of the most
nutrient dense foods on the planet so it is an ideal food for space
missions. Foods that are in their natural form, and plant based are
naturally higher in antioxidants which is important for crew members as
they are exposed to higher levels of radiation during missions. This
could leave them at risk for genetic damage. It is important that crews
are eating as many unprocessed plant based products as possible during
their missions for this very reason. An excellent form of fibre, but
also gentle on the digestive tract, and not over stimulating is
important during missions as health is a top priority. It is also an
ideal source of essential amino acids and fatty acids which will be
metabolized and utilized in the body very effectively.
