A randomized, double-blind trial in 21 Danish hospitals assessed whether sodium bicarbonate, administered during in-hospital arrest, improved sustained return of spontaneous compared to placebo.

Among adults, no significant differences were observed in the rates of sustained return of spontaneous circulation, 30-day survival, or favorable outcomes.

These findings do not support the routine use of sodium bicarbonate for in-hospital cardiac arrest and are consistent with current advanced life support guidelines.

Eat breakfast, then lunch, and your blood sugar may barely climb. Skip breakfast, eat the same lunch, and it can climb a good deal higher. The thing that changed wasn't the food. It was the morning.

This comes from a small study in healthy adults. Each person was given an identical lunch on two days, once after breakfast and once after skipping it. The rise in blood glucose after the skipped-breakfast lunch was much larger, 3.2 versus 0.9 mmol/L on average. Same meal, same people. The only thing that differed was whether anything came before it. It is a small study, so it is best held as a signal rather than a settled rule.

The insulin response looked similar on both days, which hints that insulin is not what's driving this. The leading explanation is free fatty acids. Going without food for a few hours tends to raise them, and muscle that is running on fat appears to take up less glucose. So lunch arrives and more of that sugar may stay in circulation, because the tissue that would normally absorb it is busy burning fat instead. Eat breakfast and fatty acids stay lower, which seems to leave muscle readier to handle the incoming sugar.

There is a separate piece of evidence worth knowing, though it is in a different group. In people with type 2 diabetes, a dose of arginine before lunch cut the post-lunch glucose rise by about half. Arginine triggers insulin, but it is an amino acid, not a meal, no carbohydrate involved. That points to the effect being about the state the body is in beforehand rather than how the food is digested. Worth being clear that this was a diabetic population, separate from the healthy adults in the first study.

One honest limit. These are small, acute studies measured over single afternoons. Nobody has shown that eating breakfast every day lowers long-term blood sugar or disease risk through this mechanism, and the wider research on breakfast is genuinely mixed. Treat this as interesting physiology, not a diet rule.

What it does suggest is that a single meal's glucose response may not be fixed. The same lunch might do two different things in the same body depending on what came before it. The number on a food label or a glycemic index chart could be only part of the story, with the state you were already in making up the rest.

Researchers scanned the brains of 25 first-time fathers during the first 24 weeks after childbirth and found that fatherhood triggers a major neurological remodeling process: some parts of the brain saw a reduction in the volume of grey matter while other parts grew in size.

When you microwave food in a plastic container, three things move from the container into your food: plasticizers like phthalates, residual monomers like bisphenol A, and tiny particles of the plastic itself. This happens at temperatures most people use every day. The amount is measurable in laboratory studies. Whether it matters for your health at typical exposure levels is genuinely uncertain. The honest framing is the one that doesn't oversell either direction.

The "microwave-safe" label tells you something specific. It tells you the manufacturer has determined the container won't melt, warp, or deform under typical microwave use, and that any migrating substances stay below the FDA's specific migration limits for food contact materials. It does not tell you that nothing leaves the container. The FDA standard (21 CFR 177) is built around specific migration limits, not around zero migration. Compliance means migration stays below the legal threshold. It does not mean migration is absent.

What the studies show:
Lim and colleagues (2009, Journal of Toxicology and Environmental Health) tested polycarbonate bottles by microwaving them with steamed rice or cooked pork to 100°C for 9 minutes. Bisphenol A migration into the food rose from 6 to 18 parts per billion in the rice and 5 to 15 parts per billion in the pork. These levels were well below the regulatory limit of 600 parts per billion. The migration was real and measurable. The doses were not.
Hussain and colleagues (2023, Environmental Science and Technology) measured microplastic and nanoplastic release from polypropylene containers and reusable food pouches under different conditions. Microwave heating released the most particles per square centimeter compared to refrigeration or room-temperature storage. Some containers released up to 4.22 million microplastics and 2.11 billion nanoplastics per square centimeter of plastic surface within three minutes of microwave heating. The estimated daily intake came out to about 20 nanograms per kilogram of body weight for infants drinking microwaved water. Nanograms. The cytotoxicity demonstrated in the same study was at concentrations far higher than typical real-world exposure.

A second 2024 paper (Jin et al., Journal of Hazardous Materials) found hot water exposure released comparable or greater quantities of particles than microwave heating in their setup. Heat is the variable. The microwave is one source of heat among several.

Five things that scale migration from any plastic container into food:

First, heat. Higher temperature means more migration, full stop.
Second, fat content of the food. Phthalates and BHT are lipid-soluble. Fatty foods pull more out than aqueous foods.
Third, acidity. Tomato sauce, citrus, and vinegar accelerate migration relative to neutral foods.
Fourth, container age and condition. Microscratches from dishwashing and repeated heating cycles create more surface area and more particle release.
Fifth, duration of contact. Long storage allows continued migration even at room temperature.
What this does not mean: it does not mean microwaving food in plastic is poisoning you. The doses measured in real-world conditions are typically well below regulatory limits, and the daily intake estimates are in nanograms per kilogram per day. Phthalate exposure is associated with adverse outcomes in epidemiological studies, but the dominant exposure routes are personal care products, dust, and food packaging in general, not specifically microwave heating.

What this does mean: the label "microwave-safe" is not the assurance most people read it as. Migration into food is happening every time you microwave plastic. The magnitude depends on heat, fat content, acidity, container age, and time. Standard food-grade glass and ceramic are essentially inert under kitchen conditions and don't migrate meaningfully at any temperature with typical foods. The swap from plastic to glass for reheating removes the variable entirely.

The label is about whether the container survives. Whether anything leaves the container is a separate question.
