Nutrigenomics is the study of how food affects the expression of genes. Some foods are known to be particularly powerful in their ability to influence gene expression, and incorporating them into your diet may have a range of health benefits.

Here are some examples of powerful nutrigenomic foods:

1. Blueberries: Blueberries are high in antioxidants, which have been shown to reduce oxidative stress and inflammation, and improve cognitive function. They have also been found to have an effect on gene expression related to insulin signaling and glucose metabolism.

2. Cruciferous vegetables: Vegetables like broccoli, cauliflower, and Brussels sprouts contain compounds called glucosinolates, which have been shown to have anti-cancer effects. These compounds work by affecting the expression of genes involved in cell proliferation and apoptosis.

3. Green tea: Green tea contains a compound called epigallocatechin gallate (EGCG), which has been shown to have anti-cancer, anti-inflammatory, and neuroprotective effects. EGCG has also been found to affect gene expression related to fat metabolism and insulin sensitivity.

4. Garlic: Garlic contains a compound called allicin, which has been shown to have anti-inflammatory and anti-cancer effects. Allicin has also been found to affect gene expression related to cholesterol metabolism and immune function.

5. Turmeric: Turmeric contains a compound called curcumin, which has been shown to have anti-inflammatory and anti-cancer effects. Curcumin has also been found to affect gene expression related to oxidative stress, inflammation, and immune function.

It's important to note that while these foods have been found to have powerful nutrigenomic effects, they should be consumed as part of a balanced diet, rather than relied upon as a sole source of nutrients.
