Alzheimer’s Is Best Prevented

Pre- and probiotics — Eat prebiotic foods such as onions, garlic, leeks, asparagus and bananas, and probiotic fermented foods like yogurt, kefir, kimchi and sauerkraut. Alternatively, take a probiotic supplement. Beneficial bacteria such as Bifidobacteria and Lactobacillus, and beneficial yeast like Saccharomyces boulardii, can all help rein in the endotoxin production through competitive inhibition.
Limit sugar and refined carbohydrates — High intake of sugar and refined carbohydrates can feed harmful bacteria in the gut and promote inflammation, potentially increasing endotoxin production.
Avoid resistant starches — Other carbs to avoid would be resistant starches from legumes, beans, lentils, most grains, green bananas, sushi rice and pasta. Oatmeal can also cause trouble for many. You’ll know it’s incompatible with you if you get gas and/or constipation, or if it slows your digestion. Oatmeal is also high in linoleic acid (LA), which is why I avoid it.

If you have small intestinal bacterial overgrowth (SIBO), you may also need to avoid starches like rice and cooked potatoes, as you have inhibited ability to break down the starch into glucose. As a result, these kinds of starches may impede your recovery.

Eat plenty of antioxidant-rich whole foods — Foods rich in antioxidants, such as berries, leafy greens, and other colorful fruits and vegetables, can help reduce oxidative stress and inflammation in the gut, thereby supporting gut health and reducing endotoxin production.
Choose healthy fats such as those found in avocados, coconut oil, organic grass fed butter and ghee to help reduce gut inflammation.
Optimize your omega-3 level — Consuming omega-3 fats from sources like fatty fish (salmon, mackerel, sardines) may help reduce gut inflammation and promote a healthy gut microbiome.
