Meh (with all due respect to you).
I’ve been consuming Splenda since it came on the market. My stomach is fine and I’m not fat.
Obesity from consuming Splenda is far less a concern than having a damaged intestinal flora. That could leave you wide open to opportunistic infections of drug resistant bacteria.
These are already happening at a ridiculously high rate in the US.
“Each year in the United States, at least 2 million people become infected with bacteria that are resistant to antibiotics and at least 23,000 people die each year as a direct result of these infections. Many more people die from other conditions that were complicated by an antibiotic-resistant infection.” - CDC information
