Nitrates, naturally found in green leafy vegetables and beets, can help us do the same amount of work using less oxygen. This allows athletes to exercise at a higher power output for the same amount of breath.

Drinking beet juice can reduce the oxygen cost of exercise. What about eating whole beets?
Whole beets can improve running performance. Physically fit study participants ate a cup and a half of baked beets (about a can of beets) 75 minutes before running a 5K. During the last mile of the race, the beet group pulled ahead, compared to the placebo group, who were given berries instead. While the beet group ran faster, their heart rate wasn’t any higher.

They ran faster with less effort.

Berries are a great choice for athletes, too, and not just for races. We should eat berries on days we train, as they help speed up recovery.

If nitrates are so good for us, why not just take them in a pill? Nitrate supplements have questionable safety for long-term use. Non-vegetable sources of nitrates may also have detrimental health effects, so if we want to improve our performance and our health, we should ideally obtain nitrates from whole vegetables.

Note, as I discuss in my book How Not to Age, the nitrate strategy may only be safe in the context of a plant-based diet.

A new study has found a potential link between artificial sweeteners and accelerated cognitive decline, especially in people under 60 and those with diabetes.

Researchers followed over 12,000 adults for eight years and found that those who consumed the most sugar substitutes—like aspartame, saccharin, xylitol, erythritol, acesulfame-K, sorbitol, and tagatose—had a 62% faster decline in memory and thinking skills compared to those who consumed the least.

People consuming the highest amounts (around 191 mg/day) showed signs of brain aging equivalent to an extra 1.6 years, even after accounting for factors like age, smoking, and medical conditions. While the study doesn’t prove causation, the results raise serious concerns about long-term artificial sweetener use, especially in midlife—a critical period for setting the trajectory of brain health.

Interestingly, the link was strongest in younger adults and those with diabetes, highlighting the need for further research into how these sweeteners might affect brain function and why certain groups are more vulnerable.

🔍 While more controlled studies are needed to understand the biological mechanisms, experts suggest it may be wise to limit artificial sweetener intake—not just for metabolic health, but potentially for brain health as well.
