1. Protein Quality Matters More Than You Think
That protein shake might look impressive on the label, but your body only builds with what it can use. It needs a full set of essential amino acids, and not every food delivers them equally. Animal proteins, like eggs, meat, and dairy, come ready to absorb, while plant proteins are often tied up in fibers and compounds that limit bioavailability.
When one amino acid is missing, the body can’t complete the repair process, so the extras get wasted. For balance, pair grains with legumes or mix plant and animal proteins.

2. Can Food Mimic Ozempic’s Weight-Loss Power?
As drugs like Ozempic reshape the fight against obesity, a new question has emerged: can diet alone replicate their effects?
Scientists say foods packed with fiber and polyphenols — think fruits, veggies, legumes, and nuts — can spark the same “I’m full” signal that popular weight-loss drugs do. When these foods reach your gut, they’re converted into short-chain fatty acids that naturally boost GLP-1, the hormone that calms hunger and steadies blood sugar.
Here’s the twist: how and when you eat also matters. Eating earlier in the day, or starting meals with protein and veggies before carbs, may amplify GLP-1’s effects. It’s less about restriction and more about rhythm — fueling your body the way it’s wired to feel satisfied.

NUMBER OF THE WEEK
A recent study published in the Sleep Advances journal analyzed objective sleep data from over 1,000 Australians using under-mattress sensors during the daylight saving time (DST) transition period.
Researchers found that on the night when we "lose" that hour, Australians in DST zones got 24 minutes less sleep — a disruption that echoes the body's struggle to adjust to the abrupt shift in our internal clocks. It's a reminder of how DST tinkers with our circadian rhythms, potentially leading to fuzzy focus, irritability, and even dips in productivity the next day.

4. Healthy Fats Could Keep Alzheimer’s at Bay
Scientists at the University of Missouri may have uncovered something big: a high-fat, low-carb ketogenic diet might actually protect the brain from Alzheimer’s — particularly in women carrying the APOE4 gene, which raises risk for the disease. In their study, female mice on a keto plan showed stronger brain energy and healthier gut bacteria than those eating carbs.
Some brains can’t use glucose efficiently as fuel. Ketones, produced during a keto diet, step in as a cleaner backup source. Since Alzheimer’s usually appears after 65 and can’t be reversed, experts say it’s smart to protect brain health early — and a keto diet might help keep the mind clear longer.

5. Mediterranean Diet Eases Psoriasis Symptoms by 75%
A 16-week clinical trial found that nearly half of adults with mild to moderate psoriasis who followed a Mediterranean diet achieved a 75% reduction in symptoms, while no such change appeared in the control group. Participants also reported better sleep, lower anxiety, and improved quality of life, even without weight loss.
Researchers attribute the benefits to the diet’s anti-inflammatory and antioxidant power. Packed with fruits, vegetables, olive oil, fish, and nuts, the Mediterranean pattern may calm immune overactivity and reduce oxidative stress, tackling psoriasis from within rather than through calorie restriction.
