5 Foods to Boost Your Eye Health

You’ve likely been told at one time or another that if you want healthy eyes, you need to eat carrots. And while the old adage has some truth to it because the beta carotene in carrots is converted to vitamin A – a vitamin that is needed for optimum eye health — there are other, and perhaps even better foods to eat. Here are some of those foods:

1. Spinach

Spinach as well as other dark, leafy greens like kale contain two antioxidants stored in the macula which is that part of the retina that shields the eyes from damaging light. These antioxidants are lutein and zeaxanthin. Lutein is a deep yellow pigment found in the leaves of plants, and zeaxanthin a carotenoid found in the retina of the eye and in many plants like spinach.

And since the eye has a particularly high metabolic rate – as in, they ust a lot of energy – there is an added need for antioxidant protection.

Fear of exclusion contributes to spread of fake news, research finds

WASHINGTON — Both conservative and liberal Americans share fake news because they don’t want to be ostracized from their social circles, according to research published by the American Psychological Association.

“Conformity and social pressure are key motivators of the spread of fake news,” said lead researcher Matthew Asher Lawson, PhD, an assistant professor of decision sciences at INSEAD, a business school in France. “If someone in your online tribe is sharing fake news, then you feel pressure to share it as well, even if you don’t know whether it’s false or true.”

The research was published in the Journal of Experimental Psychology: General.

The proliferation of fake news contributes to increasing political polarization and distrust of democratic institutions, according to the Brookings Institution. But fake news doesn’t always proliferate due to dark motives or a call for action. The researchers began studying the issue after noticing people in their own social networks sharing fake news seemingly without malicious intent or ideological purpose.

“Political ideology alone doesn’t explain people’s tendency to share fake news within their social groups,” Lawson said. “There are many factors at play, including the very basic desire to fit in and not to be excluded.”

One experiment analyzed the tweets and political ideology of more than 50,000 pairs of Twitter users in the U.S., including tweets sharing fake or hyper-partisan news between August and December 2020. (Political ideology was determined through a network-based algorithm that imputes ideology by looking at the types of accounts Twitter users follow.) The number of tweets between pairs of Twitter users in the same social circles were measured. Twitter users were less likely to interact with each other over time if one of them shared a fake news story and the other did not share that same story. The same effect was found regardless of political ideology but was stronger for more right-leaning participants.

A second experiment analyzed 10,000 Twitter users who had shared fake news in the prior test, along with another group that was representative of Twitter users in general. Twitter users who had shared fake news were more likely to exclude other users who didn’t share the same content, suggesting that social pressures may be particularly acute in the fake news ecosystem.

Across several additional online experiments, participants indicated a reduced desire to interact with social connections who failed to share the same fake news. Participants who were more concerned about the social costs of not fitting in were also more likely to share fake news.

While fake news may seem prolific, prior research has found that fake news only accounts for 0.15% of Americans’ daily media consumption, and 1% of individuals are responsible for 80% of fake news sharing. Other research found that election-related misinformation on Twitter decreased by 73% after Donald Trump was banned from the platform.

Many complex factors contribute to people’s decisions to share fake news so reducing its spread is difficult, and the role of social media companies isn’t always clear, Lawson said.

“Pre-bunking” methods that inform people about the ways that misinformation spreads and highlighting the importance of the accuracy of news can help reduce the spread of fake news. However, finding ways to ease the social pressure to conform in online spaces may be needed to start winning the war on misinformation, Lawson said.

Nasal augmentation, also known as rhinoplasty, is a surgical procedure that enhances the shape and size of the nose. It is a popular cosmetic surgery that can improve the appearance of the face and boost self-confidence. Nasal augmentation can also improve the function of the nose by correcting breathing problems caused by structural defects.

There are two types of nasal augmentation procedures: open and closed. Open rhinoplasty involves making an incision in the columella, the tissue that separates the nostrils. This allows the surgeon to lift the skin and tissue of the nose, giving them a better view of the nasal structure. Closed rhinoplasty involves making incisions inside the nostrils, making it a less invasive procedure. Both techniques have their own benefits and risks, and the choice of technique depends on the individual's needs.

The surgeon will typically use either autologous tissue, synthetic material, or a combination of both to augment the nose. Autologous tissue, such as cartilage from the septum or ear, provides a natural-looking and long-lasting result. Synthetic material, such as silicone implants or Gore-Tex, can also provide a satisfactory result but carries a higher risk of complications such as infection and extrusion.

Recovery from nasal augmentation typically takes one to two weeks. Patients may experience bruising, swelling, and discomfort, but these symptoms can be managed with pain medication and ice packs. Patients should avoid strenuous activity and wearing glasses or sunglasses for at least six weeks after surgery. The final result of the surgery may not be fully visible for several months as the swelling subsides and the tissues settle.

In conclusion, nasal augmentation is a safe and effective procedure that can improve the appearance and function of the nose. It is important to choose a skilled and experienced surgeon to ensure the best possible outcome. Patients should also have realistic expectations and understand the risks and benefits of the procedure before undergoing surgery.
