Avoid red meat, eggs, and high fat dairy products. Avoid immune-depressant substances such as coffee, tea, tobacco, alcohol and recreational drugs. And, indeed, an extremely healthy active person may not need to supplement his diet all the time. Again, as in all things, commonsense and discrimination should be operative words in choosing what supplements to take. Again, trust your intuition and discrimination and read the literature carefully to ensure that these products will be of benefit to you.
Every tradition encourages exercise.
From the age-old and contemporary practices of yoga, the oriental martial arts, running, swimming, dancing, skiing, or just plain walking, exercise is good for mind and body. At the mental level, exercise provides a focus for our concentration, and an outlet for expressing pent-up emotions. Exercise when practised as an art can be an exquisite meditation, the ultimate harmonization of mind and body. At the body level, movement benefits the immune system, strengthens the cardiac system and can increase flexibility, agility and coordination. We all know the above, and yet many of us, including myself, do not exercise as optimally as we could.
