Does sugar cause cancer? Another dumb myth to be debunked

Despite the widespread belief that sugar may cause cancer, there is no strong clinical evidence to support this link. While some research, like a 2017 Nature Communications paper, suggests a connection, these findings are inconclusive and don’t constitute a general claim that sugar causes cancer. Cancer is a complex disease with over 200 types, each with different causes. Lifestyle changes, like avoiding smoking and maintaining a healthy diet, can reduce cancer risk. However, the Warburg effect posits that cancer could have a unique sugar metabolism, which presents a potential research avenue for treatments. It’s important to manage sugar intake for other health reasons, but currently, sugar avoidance is not proven to prevent or treat cancer.

Severe COVID linked to risk of neurologic and psychiatric disorders

Recent research indicates that people who have been hospitalized with severe COVID-19 face a doubled risk of psychiatric or neurologic disorders one year post-infection compared to those never infected. This contrasts with mild COVID cases, which show no increased risk or even reduced risk when compared to non-COVID individuals. This evidence underscores COVID’s long-term impact on mental health, highlighting the importance of vaccines in preventing severe disease outcomes.

Do supplements prevent cancer or heart disease

Do supplements prevent cancer or heart disease? No evidence

The US Preventive Services Task Force (USPSTF) found insufficient evidence to recommend supplements for cancer and heart disease prevention, except for cases with specific medical needs. Expensive supplements generally result in “very expensive urine,” with no benefit for those without nutrient deficiencies. The USPSTF’s evaluations, which influence healthcare coverages, are based on high-quality clinical studies, leaving most supplements without support for their claimed benefits.

Don’t misinterpret FDA agreeing to dismiss lawsuit on ivermectin

Dorit Rubinstein Reiss, a UC Hastings Law Professor, critiques the FDA’s decision to settle a lawsuit demanding the removal of their anti-ivermectin statements. She argues the FDA should not have conceded to the misleading narrative that ivermectin is effective against COVID-19, emphasizing the importance of authority in issuing public health recommendations. The settlement has been misrepresented by anti-vaccine activists to challenge FDA’s credibility, despite their maintained stance that ivermectin is unsupported for treating COVID-19.

COVID vaccination lowers cardiovascular and stroke risk

Recent studies confirm COVID-19 vaccination significantly reduces the risk of cardiovascular events like heart attacks and strokes. A Korean study showed a 58% decrease in such risks post-vaccination, corroborating similar findings from previous U.S. research. The evidence is clear: vaccinations are crucial in preventing severe post-COVID complications and saving lives.

Study shows that Viagra may reduce risk of Alzheimer’s disease

Recent research supports the potential of Viagra (sildenafil) in reducing Alzheimer’s disease risk, revealing a 54% and 30% decreased incidence in two medical databases and a biologically plausible mechanism for protection against AD. However, further research is necessary, especially clinical trials, to confirm these findings and examine effects in women and the role of sexual activity.

Bivalent COVID vaccines are not linked to stroke — new research

Recent research shows that bivalent mRNA COVID vaccines do not increase stroke risk, a claim previously unverified large-scale studies. The paper in JAMA examined 5.4 million records, finding no significant stroke risk after COVID vaccines but indicated risks associated with flu vaccines, contradicting most prior research. Further analysis is called for to resolve confusion.

COVID vaccines and prion disease — zombie trope debunked

For over two decades, various discredited anti-vaccine claims have reemerged, such as the assertion that COVID vaccines lead to prion diseases. Prion diseases, several of which exist, are always fatal and typically result from misfolded proteins. Despite concerns during the UK mad cow disease outbreak, no evidence links vaccines to an increased incidence of prion diseases. Recently, anti-vaccine proponents have misinterpreted data to suggest a link between mRNA COVID vaccines and prion diseases, yet no biologically plausible mechanism supports this. Vaccination data shows no increase in prion diseases, reinforcing the safety of COVID vaccines.

Measles outbreaks in the USA are a public health problem

Physicians are concerned about recent measles outbreaks in the USA, citing misinformation as a contributing factor. Lack of public memory of measles’ severity, due to vaccine success, has lowered vigilance. Highly contagious, measles’ complications can be severe including death, with no cure but the highly effective MMR vaccine. Low vaccination rates and anti-vaccine sentiments risk exacerbating these outbreaks, undermining herd immunity and public health.
