2. Bacon
The salty cured pork varietal, bacon, is a high-purine food that is proven to increase uric acid levels in the blood and cause gout attacks. Not only that, but your average package of bacon generates loads of unhealthy saturated fats (70% of your daily recommended value per 100g) and artery-blocking cholesterol (36% of your daily recommended value). While it packs a strong punch of protein, the fat and cholesterol combined with over 1,700mg of sodium per 100g, makes bacon an ingredient that increases your risk for heart disease the more you eat it.
