In this age, there are tremendous amounts of chemicals and additives that all work together to inhibit hormones, fertility, thyroid, metabolism, cognitive function, neurological health, immune system, energy, strength, agility, nutrient absorption, etc. We should do everything we can to escape this toxic load by diligently reading ingredient labels, being aware of packaging, etc. Earlier generations didn’t have to worry about these things to such a degree. It is also important for us to examine natural “foods” - not just any additives, but the foods themselves. This way we can avoid “foods” that naturally contain anti-nutrients that contribute to this toxic burden already heaped upon us from added chemicals (often hidden, or very difficult to escape). And we can replace them with powerful foods that actually strengthen us and heal us, and even help lighten the toxic load!
In light of these goals, another great food to include in your regular diet is the pineapple. It is very low in anti-nutrients, and it has been linked to improvements in almost everything mentioned in the first sentence of this article. For example, notice pineapples aids the thyroid:
“Pineapple juice supplementation activates thyroid gland and attenuates hyperlipidemia [lowers blood cholesterol] in rats…This study aimed to assess the antioxidant activity of the pineapple crude juice extracted from the whole fruit, and its effect in stimulating thyroid hormones synthesis in hypothyroid rats…Supplementation of euthyroid [normal thyroid] rats with pineapple juice for 8 weeks reduced the body weight and elevated serum T3 and T4 levels, compared to normal controls. While, supplementing hypothyroid rats with the pineapple juice normalized serum levels of T3, free cholesterol and its percentage of esterification, LDL-C, HDL-C, atherogenic index and LCAT activity, as well as serum, heart and hepatic MDA concentration and GPX activity. The histological examination of thyroid tissue sections of hypothyroid supplemented rats revealed an improvement in the cellular architecture of the thyroid gland epithelium lining the follicles and partial filling of the follicular lumen with colloid. Pineapple juice attenuates the excessive methimazole induced oxidative stress and consequent hyperlipidemia, also, activates the thyroid gland functions, suggesting its benefit as therapeutic supplement or as an adjunct in hypothyroidism therapy.”

Pineapples contain an enzyme (bromelain) that aids in digestion, cancer-prevention (e.g., Cancer Lett. 2010 Apr 28), and so much more:
“Bromelain belongs to a group of protein digesting enzymes obtained commercially from the fruit or stem of pineapple…In vitro and in vivo studies demonstrate that bromelain exhibits various fibrinolytic [prevents blood clots], antiedematous [relieves edema or excessive water retention], antithrombotic, and anti-inflammatory activities. Bromelain is considerably absorbable in the body without losing its proteolytic activity and without producing any major side effects. Bromelain accounts for many therapeutic benefits like the treatment of angina pectoris [chest pain due to coronary heart disease], bronchitis, sinusitis, surgical trauma, and thrombophlebitis, debridement of wounds…It also relieves osteoarthritis, diarrhea, and various cardiovascular disorders. Bromelain also possesses some anticancerous activities and promotes apoptotic cell death…Evidence has suggested that bromelain counteracts some of the effects of certain intestinal pathogens like Vibrio cholera and Escherichia coli, whose enterotoxin causes diarrhoea in animals…”(Biotechnol Res Int. 2012; 2012)Not only does bromelain aid in the healing of sport’s injuries, etc., but it has also been found to limit the decreases in testosterone associated with intense exercise:“Bromelain, a mixture of proteases obtained from pineapples, has been demonstrated to reduce exercise-induced muscle damage and inflammation, enhancing recovery…This investigation aimed to establish if markers of muscle damage and testosterone were influenced by acute bromelain supplementation in competitive cyclists taking part in a six-day cycle stage race. Testosterone concentrations were significantly lower on the final day of racing (P = 0.03, d = 1.3) and there was a trend for bromelain to maintain testosterone concentrations across the race period (P = 0.05, d = 1.04-1.70) when compared to placebo. Fatigue rating was lower in the bromelain group on day four of racing (P = 0.01). Consecutive days of competitive cycling were associated with increased markers of muscle damage and a reduction in circulating testosterone across the race period. Bromelain supplementation reduced subjective feelings of fatigue and was associated with a trend to maintain testosterone concentration.”

Repeatedly, we find that “tropical fruits” possess amazing, beneficial health properties. They often inhibit heavy metal toxicity, and are anti-inflammatory.
One cup of pineapple contains 131% of the RDI of vitamin C. It is well-known that this is beneficial for our immune system, iron absorption, feelings of well-being, etc. One cup of pineapples also contains 76% of the RDI for manganese. Manganese protects against free radicals, helps prevent osteoporosis and inflammation, regulates sugar levels, insures optimal brain, muscle, and nerve functions, supports bone mineral density, etc. It has been found to promote pubertal development and testosterone in young, male rats.
Pineapples also strengthen the immune system. Notice:
“This randomized, controlled trial examined the effects of canned pineapple consumption on immunomodulation, nutritional status, and physical health of ninety-eight (98) school children… Group A (33) includes subjects who were not given canned pineapple, Group B (33) includes those who were given 140 g, and Group C (32) includes those given 280 g of canned pineapple for nine weeks… Results showed a decrease in incidence of viral and bacterial infections for both Group B and Group C (normal and underweight) after canned pineapple consumption…”
