Paired with exercise diet is the number one important element when it comes to longevity
A healthy diet when paired with anything is the best for longevity
There is significant evidence to back the fact that when you pair a healthy diet with exercise your health will be increased. In particular a healthy diet and exercise can actually increase the cognitive function of your brain. ( short-term healthy lifestyle program combining mental and physical exercise, stress reduction, and healthy diet was associated with significant effects on cognitive function and brain metabolism. Reduced resting activity in left dorsolateral prefrontal cortex may reflect greater cognitive efficiency of a brain region involved in working memory.)
Brain health is very important for longevity. There’s no point in living a long time if your brain hasn’t got the ability to sustain you. Degeneration of the brain is the number one fear for anybody when it comes to longevity. For good reason too, it is basically our main driver. Without a healthy brain we are fairly useless. As such it is very important to make sure your brain health is good.
Not only that but a well balanced diet in which you are consuming high amounts antioxidant vitamins can lower your risk of stroke, if your diet is lacking in them according to observational studies. (In observational studies (case-control or cohort design), people with high intake of antioxidant vitamins by regular diet or as food supplements generally have a lower risk of myocardial infarction and stroke than people who are low-consumers of antioxidant vitamins.)
Balance is king
The most important thing when it comes to diet is balance. There’s not one single diet our there be it; Ketogenic, Vegan, Vegetarian, Omnivore or Carnivore diets. The single diet that is the most effective is one that is high in vitamins. Contains all of your essential amino acids. Gives you approximately 1g of protein per 1lb of body weight and is whole food based. A diet with whole foods is far more beneficial to one that is only supplemented. Bare in mind even grassfed beef contains some form of supplementation. B12 is injected to ensure adequete levels, and most milk and cereals are fortified with vitamin d, calcium and iron. There is nothing wrong with this, it is more of a fail safe. What is wrong is only relying on multivitamins and eating processed foods with no nutritional value.
