Ultra-Processed Foods Linked To Brain Changes That Drive Overeating

 Overview of Ultra-Processed Foods (UPF)

- UPFs may cause the brain to overeat.

- Study involved brain scans of nearly 30,000 middle-aged adults.

- Found structural brain changes related to hunger and cravings.

Key Findings from Research

- Eating UPFs linked to changes in brain areas affecting feeding behavior, emotion, and motivation.

- Higher UPF intake connected to increased thickness in the bilateral lateral occipital cortex, indicating altered processing of visual food cues.

- UPFs associated with structural changes in hypothalamus, amygdala, and right nucleus accumbens, leading to overeating cycles.

- Increased UPF consumption linked to systemic inflammation and poor metabolic markers (CRP, triglycerides, HbA1c).

Expert Insights

- Dr. Joseph Mercola states findings are unsurprising, referencing past research on UPFs affecting insulin signaling in the brain.

- The brain requires insulin for energy; insufficient insulin impairs appetite control.

- UPFs are designed to be hyper-palatable, stimulating dopamine pathways and reinforcing consumption behavior.

- Breakdown of insulin signaling leads to difficulty in feeling full, increasing cravings.

Direct Effects on the Brain

- UPFs contain additives that might alter brain function through non-obesity-related pathways.

- Emulsifiers in UPFs could disrupt neurotransmitters and gut microbiota, leading to neuroinflammation.

- Study controlled for various factors including nutrient content and lifestyle habits.

Implications of the Findings

- Research challenges the notion that obesity is solely linked to calorie intake.

- Emphasizes that the type of food matters significantly in eating behavior.

- Validates feelings of loss of control around UPFs, indicating it’s not an individual failing.

Definition and Regulatory Implications

- UPFs are industrial products containing non-home cooking ingredients (e. g. , high-fructose corn syrup, stabilizers).

- Prior research links UPFs to increased mortality risk and health conditions.

- Researchers advocate for regulatory changes to improve public health.

Study Limitations

- While associations between UPFs and brain changes were found, causation is not definitively proven.

- Researchers noted that food processing may only be part of a larger issue, requiring further studies for causation proof.

Fauci Files Reveal Pfizer Helped Biden Rig 2020 Election

 Pfizer secretly colluded with Joe Biden's team to help him rig the 2020 election against Trump, according to new Fauci documents. In his new book, "On Call," Fauci admits that Albert Bourla, the CEO of Pfizer, called him the night after Biden was declared the winner of the election, to inform him of Pfizer's "Game-changing results" from the rigged mRNA trial. "On November 7, after the absentee ballots were counted, Joe Biden was declared the winner of the presidential election. It was the very next night that Albert Bourla, Pfizer's CEO, called me away from my neighbors' fire pit to inform me about the game-changing results from the Pfizer mRNA vaccine trial. I finally thought we had truly turned a corner in defeating this terrible disease." Today reports: In another interesting tidbit, Fauci discusses Trump's FDA Commissioner Stephen Hahn declaring that he would not go along with the Trump Administration's plan to roll out the vac...

Republicans Withdraw $1 Billion From BlackRock Due To Its ESG Policies

  Multiple U.S. states governed by Republicans are withdrawing state funds from BlackRock's management, as they disapprove of the ESG investment policies of the world's top asset manager, the Financial Times reports. In recent weeks, Louisiana, South Carolina, Utah, and Arkansas have announced they would divest funds from... For months now, Republican states have said they would not do business anymore with asset managers who have ESG-aligned investment policies, which, the states say, show that those financial firms are boycotting the oil and gas industry. Texas is leading the campaign against this movement The Lone Star State published a list of financial firms that could be banned from doing business with Texas, its state pension funds, and local governments. https://oilprice.com/Latest-Energy-News/World-News/Republicans-Withdraw-1-Billion-From-BlackRock-Due-To-Its-ESG-Policies.html

The Biden-Harris White House Has An Iranian Spy Leaking U.S. Intelligence In It

 The question is, how did classified intelligence from the United States, showing Israeli military movements that suggest broader action against Iran, get to Tehran? The answer raises uncomfortable questions for the Biden-Harris White House, which has opposed Israel every step of the way in responding to Hamas, Hezbollah, and Iran. Defying Biden got Israel the entire leadership of Hezbollah and Hamas, with the ultimate threat still looming: Iran and its nuclear program. Operations against Iran are being assessed also because Iran has started firing ballistic missiles into Israel, targeting civilian centers across the country. If Israel is close to launching a broader offensive against Iran, leaking U.S. intelligence would be a way to both try and deter Israel and give more warning to Iran. In 2012, similar allegations were made against the Obama administration when U.S. intelligence leaks showed that Israel was working towards using "Azerbaijan as a base of operations in the event...
