A recent study published on Medical News Today suggests that eating eggs just once a week may be linked to a reduced risk of developing Alzheimer’s disease.
The study found that individuals who consumed at least one egg per week had a 47% reduced risk of Alzheimer’s compared to those eating eggs less than once a month. The researchers also observed less buildup of toxic proteins associated with Alzheimer’s in the brains of those who ate eggs more regularly.
While eggs have been a subject of debate regarding cholesterol and heart disease, current research generally indicates that for most healthy individuals, moderate egg consumption (up to 7 eggs a week) does not significantly increase the risk of heart disease. However, individuals with specific health conditions like diabetes or high cholesterol may need to monitor their intake more closely.
It’s important to remember that a varied, nutrient-dense diet rich in whole foods is crucial for overall brain health and reducing the risk of various chronic diseases.

Yes, solar panels generally generate more electricity in strong sunlight. Here’s why:
See less* More Photons: Solar panels work by converting light (photons) into electricity through the photovoltaic effect. Stronger sunlight means a higher intensity of light, which translates to more photons hitting the solar cell’s surface. More photons mean more electrons are dislodged from the atoms in the solar cell material, leading to a greater flow of electric current.
* Direct Relationship: The short-circuit current (a measure of current output) from a solar cell is directly proportional to the light intensity. So, if the sunlight intensity doubles, the current output will also roughly double.
* Optimal Conditions: Solar panels typically achieve their peak performance under conditions of about 1000 W/m² of sunlight, which is characteristic of clear, sunny days with direct sunlight. This is often referred to as “peak sun hours.”
However, there are some nuances:
* Temperature: While strong sunlight provides more photons, it also increases the temperature of the solar panel. Solar panels are actually more efficient in cooler temperatures. Excessive heat can decrease their efficiency, even if the sunlight is intense. Manufacturers specify a “temperature coefficient” which indicates how much power output will drop per degree Celsius above 25°C.
* Indirect Sunlight: Solar panels can still generate electricity from indirect or diffuse sunlight (e.g., on cloudy days), but their output will be significantly lower (sometimes 10-25% of their peak output) compared to direct sunlight.
* Angle of Incidence: The angle at which sunlight strikes the panel also plays a crucial role. Panels are most efficient when the sun’s rays hit them perpendicularly. This is why solar panel installations often consider optimal tilt angles and some advanced systems use trackers to follow the sun’s path throughout the day.
* Panel Quality and Technology: Modern solar panels, especially monocrystalline ones and those with half-cut cell technology, are designed to perform better in lower light conditions and to mitigate the impact of partial shading.
In summary, for maximum electricity generation, solar panels thrive on strong, direct sunlight, ideally combined with cooler temperatures.
