What to avoid while on antibiotics?

Foods that must be avoided while on antibiotic treatment include grapefruit, foods rich in calcium, and alcohol. Grapefruit contains compounds known as furanocoumarins, which interfere with how the liver and intestines break down the medicine and filter out toxins.

What are the long term effects of antibiotics?

Disruption in host-microbe dialog can not only disrupt digestion, cause diarrhea and ulcerative colitis, but new research is also linking it to immune function, obesity, food absorption, depression, sepsis, asthma and allergies.

Do antibiotics damage human cells?

“Clinical levels of antibiotics can cause oxidative stress that can lead to damage to DNA, proteins and lipids in human cells, but this effect can be alleviated by antioxidants,” said Jim Collins, Ph.

How do antibiotics inhibit the growth of bacteria?

Often called bacteriostatic antibiotics, they prevent nutrients from reaching the bacteria, which stops them from dividing and multiplying. Because millions of bacteria are needed to continue the disease process, these antibiotics can stop the infection and give the body’s own immune system time to attack.

How do antibiotics not harm human cells?

The result is a very fragile cell wall that bursts, killing the bacterium. No harm comes to the human host because penicillin does not inhibit any biochemical process that goes on within us. Bacteria can also be selectively eradicated by targeting their metabolic pathways.

Why do antibiotics work on prokaryotes and not eukaryotes?

Antibiotics are simply chemicals that kill prokaryotic cells but do not harm eukaryotic cells. They are natural chemicals produced by fungi and bacteria that act to control their bacterial competitors. … Streptomycin does not stop protein synthesis in eukaryotic cells because it does not bind to eukaryotic ribosomes.
