However, I would like to say a few words, filial piety to the elderly, want to let the elderly live well in their later years, the most important thing is to nourish the heart, followed by health, then food supplement, and finally medicine supplement.

Food is important, but not the most important. There is not a song that sings well, "if you love me, stay with me;" If you love me, you will hug me. "

The same is true for the elderly. If you love him, play with him, listen to his nagging, walk hand in hand, inherit his ambition, do your duty and make him happy. Even vegetarianism is good for the elderly.

When it comes to spirulina, it is actually just a plant. Low-grade cyanobacteria, single-celled filaments, non-toxic and edible. Other algae foods include kelp (brown algae), cabbage (green algae), Nostoc commune (blue algae) and seaweed (red algae).

Although I have been dealing with algae and sent spirulina to the elderly, I seldom eat it myself. I try to eat more local vegetables to bask in the sun.

A light diet, radish and cabbage, ensures a safe life.
