Reading this column, Richard D. Louis Post Dispatch (In the United States), he writes: “I am 82 years old and in good health compared to most men my age.
“Spirulina – I recently started adding half a teaspoon to my breakfast. What are your thoughts on that?
“Green tea – I started drinking it because it was supposedly beneficial. How can a person know if it is useful or not?
“Because I have osteopenia, my endocrinologist wants me to eat more protein and reduce the amount of green leafy vegetables.
“Have you written an article about the nutritional value of beans?
“You write pretty clearly, so it’s easy to understand the subject. It wouldn’t surprise me if your minor is English or literature.”
You seem to be taking good care of yourself, Richard. Let’s solve your questions.
Spirulina is a type of blue-green algae that is aquatic organisms that produce energy from the sun.
A recent review in the journal molecules gives spirulina a nourishing thumbs up.
It is high in protein and other essential nutrients, including vitamin B12, which is often lacking in plant-based diets.
Spirulina also contains a number of compounds that help the body fight inflammation and boost the immune system.
Extracts of blue-green pigments are approved by the US Food and Drug Administration (FDA) as natural color additives for a variety of foods and confectionery.
And get this, NASA used spirulina as a nutritional supplement for astronauts.
However, some caveats remain.
People with autoimmune disorders such as multiple sclerosis or taking immunosuppressive drugs should avoid spirulina supplements because of its immunostimulating effect.
Pregnant and breastfeeding women and young children should avoid it, as some unregulated products may contain unwanted contaminants.
How can you tell if green tea is beneficial?
As we know that seat belts save lives.
Research shows that green tea (and other types of tea) camellia sinensis herb) may help lower blood pressure and cholesterol, and may even protect against cancer and other chronic diseases.
By the way, green, black and oolong teas are from the same plant; they are just handled differently.
Yes, I wrote a column recently on the value of beans.

Thanks for the compliment, but my minor was cowboys, not English literature.
As a sophomore (college sophomore) I had hopes of becoming a sophomore teacher before I majored in food science and nutrition.
Perhaps this limit in education has helped. – by Barbara Intermill/Tribune News Service
