Aside from the UCLA study data, avocados are one of the rare fruit that contain an excellent source of healthy fat. They are fantastic as part of a salad, because the fat within the avocado greatly increases your body’s ability to absorb the nutrition in the rest of your food.
Many nutrients require fat to transport them into the body, which is the biggest problem with low-fat diets that can leave you malnourished. Eating avocado in combination with other fruit and vegetables, has been shown to increase your absorption of lutein four times over, your absorption of alpha-carotene, eight times over, and boost your absorption of beta-carotene, a whopping 13 times over! Beta-carotene has excellent anti-cancer properties, so being able to increase its absorption is very important.
Avocados are also rich in the amino acid tryptophan, with a side order of vitamin B6 and folic acid. These key nutrients are used in the synthesis of serotonin, which is the feel-good neurotransmitter in your brain. Serotonin is vitally important when it comes to elevating your mood and fending off depression. As you will see in the psychology section of this book, your mood can have a drastic impact upon survival rates, so never underestimate the value of looking after your emotional health.
Finally, avocado contains natural antibiotic and antifungal chemicals.
