The three biggest risk factors for dementia


Researchers have identified modifiable factors like diabetes, air pollution, and alcohol as significantly increasing dementia and Alzheimer’s disease risks. Additionally, genetic factors affecting brain regions were noted, although they cannot be modified. The study emphasizes the complexity of these diseases and suggests healthy diet, active lifestyle, and social interaction as potential risk mitigators.

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.

DNA fragments in COVID vaccines aren’t linked to cancer


     2   5  7SharesFlorida Surgeon General, Joseph Ladapo, MD, Ph.D., has continued to claim That COVID vaccines may be contaminated with DNA that can lead to various health issues like cancer. I have debunked this, but still, more and more anti-vaccine activists push… Read More »DNA fragments in COVID vaccines aren’t linked to 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.


measles vaccinations

Measles surges in the USA — we need more vaccinations


Despite the near eradication of measles in the USA, cases are surging due to insufficient vaccinations. Measles is a serious respiratory disease with possible deadly complications for children, particularly those under 12 months old who cannot be vaccinated. The CDC has responded to the 64 cases reported in 2024 with vaccination advisories. Vaccination remains the safest, effective prevention, disproving anti-vaccine claims linking MMR to autism. International travel has been linked to most U.S. cases; hence, vaccination is critical for those traveling.

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

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.
